B. Exterior Chase Installation: (See Figure 4). A chase is an enclosure built specifically to house a chimney. The interior of a chase is open from Model 51ZC to the roof, eliminating the need to cut through ceilings and the roof. Normally, a chase is built through the wall, and the Model 51ZC is located in the bottom of the chase, with the front of the unit flush with the interior wall. Chases are commonly veneered on the outside with brick, stone or wood to give the appearance of a conventional fireplace flue. Occasionally, they are built inside and boxed in, similar to a stairwell. When making a chase installation, it is important to read the chimney manufacturer’s instructions prior to building, as there are specific requirements for bracing a free standing flue that must be planned for. There are also occasions where offsets are used within a chase to accommodate unusual building designs, or to locate the Model 51ZC further into a room.

Floor Protection: or Hearth Protector
Floor protection must be 3/8″ minimum thickness non-combustible material or equivalent.
How to use alternate materials and how to calculate equivalent thickness.
An easy means of determining if a proposed alternate floor protector meets requirements listed in the appliance manual is to follow this procedure:
1. Convert specification to R-value: R-value is given–no conversion is needed. K­ factor is given with a required thickness (T) in inches: C-factor is given: R=1/C
2. Determine the R-value of the proposed alternate floor protector. Use the formula in step (1) to convert values not expressed as “R” For multiple layers, add R-values of each layer to determine the overall R-value.
3. If the overall R-value of the system is grater than the R-value of the specified floor protector, the alternate is acceptable.

Example: The specified floor protector should be 3/4″ thick material with a K-factor of 0.84. The proposed alternate is 4″ brick with a C-factor of 1.25 over 1/8″ mineral board with a K-factor of 0.29.

Step (a): Use formula above to convert specification to R-value. R= 1/K x T = 1/0.84 x .75 = 0.893

Step (b): Calculate R of proposed system. 4″ brick of C=1.25, therefore Rbrick = 1/C = 1/1.25 =0.80 1/8″ mineral board of K = 0.29, therefore Rmin.bd. =1/029 x0.125 = 0.431

Step (c): Compare proposed system R of 1.231 to specified R of 0.893. Since proposed system R is greater than required , the system is acceptable.

Definitions: Thermal conductance = C = Btu = W (hr)(ft²)(°F) (m²)(°K)

Thermal conductance = K = (Btu)(inch) = W = (Btu) (hr)(ft²)(°f) (m)(°K) (hr)(tf)(°F)

Thermal conductance = R = (ft²)(hr)(°F) = (m²)(°K)

Install in accordance with 24 CFR, Part 3280 (HUD).

FRAMING CONSTRUCTION AND INSTALLATION
Except as noted, the 51ZC can be installed almost anywhere you desire. There are, however, a few clearance and framing restrictions that must be followed. (See Page 10 Figure 9), and (Page 11 Figure10) to make sure that these clearance restrictions are met. It is much wiser to place your Model 51ZC correctly at the start.
You must ensure that the floor is of adequate strength to accept the load of this unit. If inadequate, the floor will require additional support, such as bracing. NOTE: A wooden base constructed of plywood or 2″ x 4″ boards is required in order to get proper clearance above the extended hearth (millboard, rock stone, etc.).
Good planning is essential for a satisfactory installation, therefore, at this point you should have decided where the 51ZC is to be located and the route the chimney will follow to the roof-straight up or chase. If you cannot decide the best route, contact your Dealer for assistance with the planning.

The base for the Model 51ZC must be level with or slightly higher than the “finished” hearth height dimension (A) Figure 6.

Framing must be accomplished after the Model 51ZC is set in place. The chimney can be installed after framing, but installation is considerably more difficult and in some cases, impossible. Therefore, it is recommended that the chimney be installed prior to framing when a choice exists. Figure 5 on the previous page shows framing location examples with depth dimensions for some typical configurations. These are finished measurements so install accordingly.
NOTE: Before framing, combustible floor coverings (carpets, tiles, etc.) must be removed to outer
dimensions of the unit framing, including the 16″ x 37 1/2″ area for the hearth extension.

With the floor protector or hearth extension material specified as one layer of 2″ thick brick with a K factor of 5.0, you may use alternate materials as long as the K factor (s) is calculated as follows:
Formula: Required thickness = (K of alternate material/K of millboard) X (thickness of millboard) Example: An alternate inorganic non-combustible millboard with a K of .9375 would require a thickness
as follows: Required thickness = .9375.0o x 2 inch
= 3/8 inch

Page 16

K Factors of Alternate Materials:

Material Ceroform 126 Limestone Concrete Sandstone Marble

K .21 8.0 8.0
13.0 18.0

Required Thickness 1/8″ 3.2″ 3.2″ 5.2″ 7.2″

Hearth extension or floor protector thickness above four (4) inches is generally not acceptable due to cost, floor load capacity, and look. The alternate we recommend is using Ceroform No. 126 millboard 1/8″ thick minimum and putting any type decorative brick or stone (any thickness) on top of it.

The K factor represents the thermal conductivity of a material and is the time rate of heat flow through a homogeneous material under steady-state conditions, through unit area, per unit temperature gradient in the
direction perpendicular to a surface.

9. The next step is the electrical installation. NOTE: An electrician must wire the 51ZC into the home wiring system using No. 15 AWG (with ground wiring) as minimum in accordance with local wiring codes.

CAUTION: Stove is plugged into cabinet receptacle.

A. Remove brass trim. B. Remove top panel and right side panel. C. Now an electrician must do the wiring.

9. Finish the wall around the 51ZC using brick, rock, sheetrock, paneling, or any type finishing material. CAUTION: Do not block any openings designed into the unit.
10. Install a mantel above the unit if desired. Note that a combustible mantel must be positioned at least 30 1/2″ above the top of the stove.
11. The 51ZC and Model 51,T51,74 or T-74 fireplace are now ready for use. Refer to the stove owners manual for operation, safety, and chimney maintenance. Refer to the back of this manual for 51ZC warranty registration information.

Page 17

CLEANING THE UNIT
A. The unit should be lightly sanded with fine sandpaper or steel wool, then repainted or touched up with high temperature black paint.
B. If the unit is located in a moist or damp location, check thoroughly for signs of condensation during times when the unit is not in use.
C. When the heating season is over, the unit can be cleaned out completely with a wire brush or cloth to help eliminate ash and burned wood smell.
SAFETY PRECAUTIONS
1. Use smoke detectors around the stove as well as in sleeping areas. 2. Keep a fire extinguisher rated for Class “A” fires near the stove. 3. Check with your insurance company to be sure your policy covers the installation and use of a wood burning
appliance. 4. Creosote-Formation and Need for Removal: When wood is burned slowly, it produces tar and other organic
vapors, which combine with expelled moisture to form creosote. The creosote vapors condense in the relatively cool chimney flue of a slow-burning fire. As a result, creosote residue accumulates on the flue lining. When ignited this creosote makes an extremely hot fire. The connector and/or chimney should be inspected at least once every two months during the heating season to determine if a creosote buildup has occurred. If creosote has accumulated, it should be removed to reduce the risk of a chimney fire. 5. Locate furniture and any other combustibles away from the stove. 6. Store firewood at a safe distance from the stove. 7. Disposal of Ashes: Ashes should be placed in a metal container with a tight fitting lid. The closed container of ashes should be placed on a non-combustible floor or on the ground well away from all combustible materials, pending final disposal. If the ashes are disposed of by burial in soil or otherwise locally dispersed, they should be retained in the closed container until all cinders have thoroughly cooled. 8. Always exercise caution when using your fireplace. Be particularly careful when there are children around an operating fireplace.
CAUTION: NEVER use gasoline, gasoline-type lantern fuel, kerosene, charcoal lighter fluid or similar liquids to start or “freshen-up” a fire in the fireplace. Keep all such liquids well away from the stove when it is in use. All fluids of this type give off highly volatile fumes and can and WILL EXPLODE! Don’t take a chance with the safety of your home and family.

PREVENTIVE MAINTENANCE/ SAFETY PRECAUTIONS
CHIMNEY
A. The chimney should be cleaned as necessary to remove creosote, soot, leaves, bird’s nests, etc.
CREOSOTE-FORMATION AND NEED FOR REMOVAL
When wood is burned slowly, it produces tar and other organic vapors, which combine with expelled moisture to form creosote. The creosote vapors condense in the relatively cool chimney flue of a slow-burning fire. As a result, creosote residue accumulates on the flue lining. When ignited this creosote makes an extremely hot fire.
The chimney connector and chimney should be inspected at least once every two months. More frequent inspection and cleaning may be necessary. Under certain conditions of use creosote build-up may occur rapidly.
Creosote is caused by low temperatures in the chimney, which is controlled by the operator of the stove.
B. A neglected chimney can eventually cause a draw restriction or can ignite and burn hot enough to cause damage to the chimney.
C. For proper inspection the chimney should be cleaned.
CHIMNEY CLEANING:
1. Access-Chimneys must be installed so that access is provided for inspection and cleaning.
2. When to Clean-The chimney should be inspected at least once every two months during the heating season to determine if creosote or soot has built up. Check spark arrestor screens every 2-4 weeks. If creosote or soot has accumulated, it should be removed to reduce the risk of chimney fire.
3. How to Clean-Have your chimney cleaned by a professional chimney sweep if you have doubts about your ability to clean it, using a plastic, wood, or steel brush. Do not use a brush that will scratch the stainless steel liner of your chimney. Scrub the spark arrestor with a wire brush.
To remove the chimney cap for cleaning, unscrew the four screws that attach the cap’s support legs to the cap base. The top cleanout cap can be removed once the screws are unscrewed. Remember to replace the screws when you are through cleaning the chimney. 4. No Chemical Cleaners-Do not use chemical chimney cleaners. Their use does not eliminate the need for mechanical cleaning and they may be highly corrosive. 5. In Case of Fire-If a flue fire occurs, close all appliance draft openings and call your Fire Department. Do not use the chimney again until it is inspected for possible damage. 6. Chimney Protection-Painting. To increase chimney life, coat all exterior metal parts with high temperature rust-proof paint. This is highly recommended, particularly in areas near the ocean. Wash the metal with a vinegar and water solution before painting.

CAUTION
YOUR CHIMNEY OR FLUE MUST BE CORRECTLY SIZED. A CHIMNEY OR FLUE THAT IS TOO SMALL OR LARGE IN DIAMETER, OR TOO SHORT, CAN CAUSE YOUR STOVE TO SPILL SMOKE WHEN DOOR IS OPENED.
SECTION I
INTRODUCTION
Your new MODEL 21 is a non-catalytic unit designed to meet the most stringent emissions standards without the use of a catalytic combustor. This effect is achieved through the use of secondary air which is mixed with primary air in the unit’s firebox.
For peak performance, we suggest the use of hard seasoned natural wood, loading wood length way from front to rear.
NOTE: Soft woods such as pine, create more creosote, clogging of chimney and produce a less efficient burn performance.
You should not burn trash or garbage, artificial or paper logs, gift wrapping, treated or painted wood or any type of coal.
DO NOT USE CHEMICALS OR FLUIDS TO START THE FIRE. DO NOT BURN GARBAGE OR FLAMMABLE FLUIDS.”
The primary air, which is controlled by the user, burns the wood. Secondary air is admitted into firebox through secondary air tubes at top of the firebox. This secondary air burns impurities in the smoke released from initial wood burning. The temperature necessary for this combustion is maintained through the firebrick refractory. If any more technical information is necessary, contact your local dealer.
A factory-built prefabricated chimney may be used for your unit when installed in compliance with the manufacturer’s specification and uniform building code.
These units may also be used with optional room air blower. To order optional motor assemblies you must specify the stove model number and give one of the following part number:
*Model 21 Motor Assembly–MA5126715
For operation and use of these electrical assemblies, see instructions provided with the motor assembly kits.

SECTION II
MASONRY INSERT INSTALLATION
The Model 21 may be installed using an all masonry fireplace built in accordance with the Uniform Building Code and National Fire Protection Association (NFPA). The first step in this type of installation is to determine the acceptability of fireplace and chimney for use with a woodstove. Both construction and condition of fireplace are important considerations when installing a woodstove. The chimney should extend at least 3′ above roof and at least 2′ above any point of the roof within 10′.
CAUTION
REMEMBER TO HAVE YOUR CHIMNEY INSPECTED FOR LEAKS AND BLOCKAGE BEFORE YOU INSTALL YOUR STOVE. DO NOT CONNECT THIS UNIT TO A CHIMNEY FLUE SERVING ANOTHER APPLIANCE.

1. The hearth must be of masonry construction and must extend a minimum of 16″ in front of firebox opening and a minimum of 8″ to either side of the firebox opening. (See Figure 1).
2. If there is not minimum hearth protection from the front of firebox opening and front of masonry hearth, a floor protector must be used in front of hearth to protect combustible materials. The floor protector must be 3/8″ minimum thickness non- combustible material or equivalent.(See Page 5).

Page 5

Floor Protection:

When installing freestanding heater, a floor protector must be use. Floor protector must be 3/8″ minimum thickness non-combustible material or equivalent.

How to use alternate materials and how to calculate equivalent thickness

An easy means of determining if a proposed alternate floor protector meets requirements listed in the appliance manual is to follow this procedure:

1. Convert specification to R-value: R-value is given–no conversion is needed. K-factor is given with a required thickness (T) in inches: C-factor is given: R=1/C
2. Determine the R-value of the proposed alternate floor protector. Use the formula in step (1) to convert values not expressed as “R” For multiple layers, add R-values of each layer to determine the overall R-value.
3. If the overall R-value of the system is grater than the R-value of the specified floor protector, the alternate is acceptable.
Example: The specified floor protector should be 3/4″ thick material with a K-factor of 0.84. The proposed alternate is 4″ brick with a C-factor of 1.25 over 1/8″ mineral board with a K-factor of 0.29.
Step (a): Use formula above to convert specification to R-value. R= 1/K x T = 1/0.84 x .75 = 0.893
Step (b): Calculate R of proposed system. 4″ brick of C=1.25, therefore Rbrick = 1/C = 1/1.25 =0.80 1/8″ mineral board of K = 0.29, therefore Rmin.bd. =1/029 x0.125 = 0.431
Step (c): Compare proposed system R of 1.231 to specified R of 0.893. Since proposed system R is greater than required , the system is acceptable.

NOTE: If the three suggested installations have been chosen, certain steps must be followed when installing heater into a masonry fireplace.
When positioning heater, the following conditions MUST be met! (See Figure 2).
1. The front of damper opening must be positioned BEHIND back edge of the lintel to ensure proper draft. (See Figure 2).
2. Center heater in fireplace opening.

MOUNTING THE TRIM PANELS
After unit is positioned as shown in (Figure 2), mark mounting position of trim panels as follows:

1. Place side trim panels in place, flat against the face of the fireplace. Mark down front edge of trim panel with a pencil to make a vertical reference line. (See Figure 3).
2. Place top (long) trim panel in place on top of unit. The panel should be flat against the outside face of fireplace and standing vertically. Mark along lower edge of trim panel with a pencil to make a reference line for mounting.

FIGURE 3

MOUNTING TRIM PANELS

3. Slide unit out of the fireplace far enough to work behind trim panel reference lines. 4. Mount side trim panels. (See Figure 3).
a. Position trim panel on reference line. b. Drill mounting holes in center of trim panels mounting brackets to allow for adjustment in and out if
necessary. c. Mount trim panel using self-tapping screws provided. 5. Place top panel back on reference mark. Take top trim panel mounting bracket supplied with unit. Position bracket so it overlaps rear lip of top trim panel. Drill mounting holes in top of stove using holes in bracket as guide. Tighten down screws. 6. Now, follow installation procedures in the listed direct connect or positive connect kit you are using and install heater connect kit in the fireplace. 7. Slide unit back into fireplace. Check to be sure that trim panels are properly positioned and lie flat against front of fireplace. If one or more of the panels is out of position, slide unit out and reset by loosening mounting screws and repositioning in slot. 8. Reinstall top trim panel by sliding rear lip of top trim panel underneath front lip of mounting bracket already secured to top of unit. NOTE: Mount top trim panel so that it sits in front of top of side trim panels. 9. Obtain brass trim kit provided with unit and slip over top and sides of trim panels. (Top ends of brass may need to be trimmed to fit).

Page 9

10. If direct connect or positive connect kit is not used, follow instructions in mounting trim panels, steps 1-4c on page 8.
11. Mount top trim panel by drilling mounting holes in center of trim panel mounting brackets, with top end side of top panel overlapping side panel.
12. Using insulation provided, peel and stick to back of panels overlapping fireplace dimensions by 1″ on each side and top. (See Page 8, Figure 3).
13. Next using high heat silicone or furnace cement run heavy bead of caulking around where panels meet stove. (See Figure 4).
14. Slide the unit back into fireplace. Check to be sure that trim panels (and brass) are properly positioned and lie flat against front of fireplace. If panels are out of position, slide unit out and reset by loosening mounting screws and repositioning in the slot. Using the bar, lift stove in front. Place insulation across front and the surface of hearth or bottom of fireplace, to make complete seal.
15. To check seal of panels, use candle flame and go around entire area sealed by silicone and insulation. If flame leans toward inside of fireplace, add additional insulation. This ensures an airtight seal.

FINAL CHECK

FIGURE 4

1. Recheck specified clearances.

2. Remove all foreign material from firebox area.

3. Open the primary air draft.

4. Plug power cord into a 115V AC outlet if optional motor is being used. Do not run cord under unit or in high traffic areas.

5. Place crumpled pieces of newspaper in the stove. Light it and close door. Ensure that the stove draws properly through primary draft.

6. Check for smoke leaks around door.

7. Open door and check for smoke escaping from front of stove. Smoking usually indicates a defective or poorly positioned chimney. Some chimneys with a marginal draft can be preheated by lighting newspaper and holding it near open damper with a poker or fire tong. Once the chimney heats up, a proper draft can usually be obtained.

If a thorough review of the Troubleshooting Guide in the manual does not reveal the problem, contact your dealer for assistance.

Floor Protection:

Floor protection must be 3/8″ minimum thickness non-combustible material or equivalent.

How to use alternate materials and how to calculate equivalent thickness

An easy means of determining if a proposed alternate floor protector meets requirements listed in the appliance manual is to follow this procedure:

1. Convert specification to R-value: R-value is given–no conversion is needed. K-factor is given with a required thickness (T) in inches: C-factor is given: R=1/C
2. Determine the R-value of the proposed alternate floor protector. Use the formula in step (1) to convert values not expressed as “R” For multiple layers, add R-values of each layer to determine the overall R-value.
3. If the overall R-value of the system is grater than the R-value of the specified floor protector, the alternate is acceptable.
Example: The specified floor protector should be 3/4″ thick material with a K-factor of 0.84. The proposed alternate is 4″ brick with a C-factor of 1.25 over 1/8″ mineral board with a K-factor of 0.29.
Step (a): Use formula above to convert specification to R-value. R= 1/K x T = 1/0.84 x .75 = 0.893
Step (b): Calculate R of proposed system. 4″ brick of C=1.25, therefore Rbrick = 1/C = 1/1.25 =0.80 1/8″ mineral board of K = 0.29, therefore Rmin.bd. =1/029 x0.125 = 0.431
Step (c): Compare proposed system R of 1.231 to specified R of 0.893. Since proposed system R is greater than required , the system is acceptable.

FINAL CHECK
1. Recheck specified clearances. 2. Remove all foreign material from firebox area. 3. Open primary air draft. 4. Plug power cord into a 115V AC outlet when using with optional motor. Do not run cord
under unit or in high traffic areas. 5. Place crumpled pieces of newspaper in the stove. Light it and close the door. Ensure that
stove draws properly through primary draft. 6. Check for smoke leaks around the door.
CAUTION
Open the door and check for smoke escaping from the front of stove. Smoking usually indicates a defective or poorly positioned chimney. Some chimneys with a marginal draft can be preheated by lighting newspaper and holding it near open damper with a poker or fire tong. Once the chimney heats up, a proper draft can usually be obtained.
If a thorough review of the Troubleshooting Guide in the manual does not reveal problem, contact your dealer for assistance.
CAUTION
The unit is painted with a specially formulated high temperature paint that cures during the first two or three firings. You may notice a slight smoking effect and an odor of burning paint when you build the first fires. This is normal and is not a cause for alarm. In some cases, these fumes will activate a smoke alarm. Opening a window near the unit will allow these fumes to escape. DO NOT build a large, roaring fire until this curing is complete or heater finish may be damaged.

PEDESTAL

This model is designed for connection to any listed 2100º UL103 HT chimneys and parts. Follow chimneys manufacturer’s instructions carefully.

This room heater must be converted to (1) a chimney complying with the requirements for

Type HT chimneys in the Standard for chimneys, Factory-Built, Residential, Type and

Building Heating Appliance, UL 103, or (2) a code approved masonry chimney with a flue

liner.

Page 30

Floor Protection:

Floor protection must be 3/8″ minimum thickness non-combustible material or equivalent.

How to use alternate materials and how to calculate equivalent thickness

An easy means of determining if a proposed alternate floor protector meets requirements listed in the appliance manual is to follow this procedure:

1. Convert specification to R-value: R-value is given–no conversion is needed. K-factor is given with a required thickness (T) in inches: C-factor is given: R=1/C
2. Determine the R-value of the proposed alternate floor protector. Use the formula in step (1) to convert values not expressed as “R” For multiple layers, add R-values of each layer to determine the overall R-value.
3. If the overall R-value of the system is grater than the R-value of the specified floor protector, the alternate is acceptable.
Example: The specified floor protector should be 3/4″ thick material with a K-factor of 0.84. The proposed alternate is 4″ brick with a C-factor of 1.25 over 1/8″ mineral board with a K-factor of 0.29.
Step (a): Use formula above to convert specification to R-value. R= 1/K x T = 1/0.84 x .75 = 0.893
Step (b): Calculate R of proposed system. 4″ brick of C=1.25, therefore Rbrick = 1/C = 1/1.25 =0.80 1/8″ mineral board of K = 0.29, therefore Rmin.bd. =1/029 x0.125 = 0.431
Step (c): Compare proposed system R of 1.231 to specified R of 0.893. Since proposed system R is greater than required , the system is acceptable.

SECTION VI OPERATION
This section of the manual is to help you get the maximum efficiency and maximum smoke (particulate) reduction from your heater. If you should experience any difficulty or have any questions concerning your heater, contact your dealer for assistance. The manufacturer recommends that for maximum performance burn dried natural seasoned hard wood.
Build a fire for maximum efficiency. These models burn wood and extract heat so efficiently, a large fire is not necessary. A large fire not only wastes energy, it usually results in the home being too warm for comfort.
The following steps will serve as a guide for operating your stove.
BUILDING A FIRE
1. Open door. 2. Open primary air control under hearth, push in. To close pull all the way out. 3. Twist two pieces of non-colored newspaper into a roll and place them on the floor of firebox. 4. These models are not designed for the use of grates, andirons or other methods of supporting
fuel. NOTE: Do not use grate or elevate fire. Build wood fire directly on inner bottom of fire
box. 5. Lay several pieces of dry kindling on top of newspaper. 6. Place three or four small pieces of firewood, 2-3″ in diameter, on top of kindling. 7. Light newspaper in the front. Close and latch door. Don’t leave fire unattended at this point.
The draft system of heater should start quickly. It may be necessary to preheat chimney to get the draft started. To do this, open door and add newspaper to top rear of wood. Light or let this paper ignite and allow to burn while holding door slightly cracked. Once draft has started, close and lock door. You are over heating the unit if the chimney and or connector glows red. 8. After embers and a coal bed have been established, load heater with dried natural seasoned hard wood.
NOTE: THE FUELING DOOR MUST REMAIN CLOSED DURING OPERATION. NOTE: If optional blower is being used on the Model 21. Your stove is equipped with a
automatic thermostat. When the stove gets hot enough, the thermostat will activate the room air blower. Set fan speed according to desired heat output. NOTE: When refueling or removing ashes turn “OFF” room air blower. Be sure to turn room air blower back on when finished. NOTE: Do not run power cord underneath heater or in walk way or heavy traffic areas.

MAINTENANCE
DOOR GASKET REPLACEMENT (COLD HEATER)
To replace deteriorated gaskets, following steps must be taken to ensure proper installation of gaskets.
1. Obtain proper gaskets and silicone glue from your local dealer. 2. Using pliers, remove any worn and deteriorated gaskets. 3. Using a scraper, wire brush and sandpaper or steel wool, clean glue and gasket residue from door frame. 4. Measure and cut gaskets to length. Care should be taken not to stretch gaskets. What you want is a full and
loose gasket weave after attachment to framing. 5. Obtain silicone glue and run a 3/16″ bead inside door frame. 6. Obtain gasket (s) and place in gasket channel areas starting at lower right corner, see below. Use a
technique which assures that gasket is applied in a loose like manner. DO NOT STRETCH GASKETS. 7. After gasket (s) are applied to glue, use your finger and go over all gasket gently pressing gasket to the
channel. Use same pressure against gasket so that final result is an evenly applied gasket. 8. Leave door open and allow at least two (2) hours for glue to dry. 9. Once gaskets are checked, heater is ready for use. 10. This should be done annually. Allowing gaskets to deteriorate can cause over-firing and shorten burn time.

! NOTE: A chimney cap should be installed to prevent moisture from entering chimney, to prevent sparks and
burning materials from escaping chimney and to keep birds and foreign materials from entering.

• NOTE: Some areas may require an approved spark arrestor.
  CLEANING THE HEATER
  A. The heater should not be cleaned with any type of detergent as most all detergents have an oil base and cannot be painted over.
  B. The heater should be lightly sanded with fine sandpaper or steel wool, then repainted or touched up with high temperature paint.
  C. If the heater is located in a moist or damp location, check thoroughly for signs of condensation during times when heater is not in use.
  D. When heating season is over, heater should be cleaned out completely with a wire brush or cloth to help eliminate ash and burned wood smell.
  CARE OF GLASS DOOR
  The glass door on your heater permits you to enjoy the beauty of the fire while retaining efficiency of your heater. Although brand of glass used in heater door has well established and recognized heat resistant and strength characteristics, it can be broken through improper care. To achieve maximum utility and safety of your glass door, we advise that you observe following use and safety tips:
  1. Inspect glass regularly for cracks or breaks. If you detect a crack or break extinguish fire immediately and return door to your dealer for glass replacement before further use.
  2. Do not slam heater door or otherwise impact glass. When closing door, make sure that no logs or other objects protrude or impact against glass.
  3. Do not clean glass with materials which may scratch it (such as steel wool) or otherwise damage glass. Scratches on the glass can develop into cracks or breaks.
  The glass can be cleaned with a commercial oven cleaner, providing it does not contain abrasives. A build-up on glass that has been there for a considerable length of time can be burned off with a propane
  Page 42

SECTION VIII
WOOD HEATER SAFETY
Certain safety hazards are inherent in any wood heater installation. You should be aware of these so that a safe and proper installation can be made.
1. FAULTY CHIMNEY: An older masonry chimney should be thoroughly checked to be sure there are no holes or weak spots which could allow sparks or hot gases to escape.
2. HEAT CONDUCTION: Placing combustible materials too close to a heater or chimney can be a fire hazard.
By keeping these particular hazards in mind as you install and use your room heater you can ensure a safe, reliable installation.
The chimney and chimney connector should be inspected once every two months. Any build-up of soot should be removed to prevent risk of a chimney fire. To remove chimney or chimney connector, remove screws or fasteners then remove pipe and clean with steel brush. Replace chimney or chimney connector. Replace screws and/or fasteners.
CAUTION
NEVER USE GASOLINE, GASOLINE TYPE LANTERN FUEL, KEROSENE, CHARCOAL LIGHTER FLUID OR SIMILAR LIQUIDS TO START OR “FRESHEN UP” A FIRE IN THE HEATER. KEEP ALL SUCH LIQUIDS WELL AWAY FROM STOVE WHEN IT IS IN USE. ALL FLUIDS OF THIS TYPE GIVE OFF VOLATILE FUMES AND CAN AND WILL EXPLODE! DON’T TAKE A CHANCE WITH SAFETY OF YOUR HOME AND FAMILY.
CAUTION: Never remove ashes from heater with blower running.
DISPOSAL OF ASHES: Ashes should be placed in a metal container with a tight fitting lid. The closed container of ashes should be placed on a noncombustible floor or on the ground, well away from all combustible materials pending final disposal. If ashes are disposed of by burial in soil or otherwise locally dispersed, they should be retained in closed container until all cinders have thoroughly cooled.
CREOSOTE–FORMATION AND NEED FOR REMOVAL: When wood is burned slowly, it produces tar and other organic vapors, which combine with expelled moisture to form creosote. The creosote vapors condense in the relatively cool chimney flue of a slow-burning fire. As a result, creosote residue accumulates on flue lining. When ignited this creosote makes an extremely hot fire.
