Description

• The ODSR Series “A” fireplaces are clean-faced, solid fuel, woodburning fireplaces.

Precautions

MHSC Fireplaces and component parts have been highly tested and will operate safely when installed in accordance with instructions provided in this manual.
Carefully read and understand all instructions before beginning installation.

If you notice any damage to fireplace or component parts, immediately report damage to your MHSC dealer.
Only use MHSC components or the warranty will be voided and a fire hazard may be created. MHSC warranty will be voided by and MHSC disclaims any responsibility for the following actions:

• Installation of any damaged fireplace or chimney component;
• Modification of fireplace, chimney assembly or anycomponent parts thereof; (except for chase flashings as detailed in MHSC Chimney Top installation instructions).
• Installation other than as instructed by MHSC; or
• Installation and/or use of any component part not manufactured or approved by MHSC in combination or assembly with a MHSC fireplace system, notwithstanding any independent testing laboratory or other third party approval of such component parts or accessory.

Any such action may possibly cause a fire hazard.
Consult local building codes to ensure that you are in compliance before installing the fireplace.
Fireplaces must be vented to the out-of-doors.
WARNING: To avoid the risk of damaging fireplace materials and increasing the risk of spreading a fire, do not use the fireplace to cook or warm food.
Do not obstruct or modify air inlets/outlets in any manner.
Do not install combustible materials on any of the fireplace surround.
Burn only solid wood fuel or gas logs.
Do not install a solid fuel burning insert or other products not specified for use with this fireplace.
These fireplaces are not approved for installation in mobile homes.This fireplace is not designed to be water tight.
Therefore, when installing this unit against an exterior wall, the wall must be finished before setting unit in place.

Moisture Resistance

• This outdoor fireplace will shed moderate amounts of water, but is not waterproof. Water and condensing water vapor may enter the chase under certain conditions.
• The fireplace will not perform as an exterior wall. Moisture penetration must be considered for construction that places the fireplace in structure walls or on moisture sensitive surfaces.
• When installed on exterior walls: MHSC recommends the fireplace chase be constructed outside the structure’s weather envelope. Where the platform meets the wall, use a flashing detail similar to that required for attached decks. Chase platforms, including hearths should slope away from the structure at 1/4 in per foot. The fireplace can be shimmed level.
• When installed on surfaces where water may collect or cause damage: MHSC recommends a slope of 1/8 into 1/4 in per foot towards the drain port suggested. The fireplace can be shimmed level.
• Hearths should slope away from the front of the fireplace and chase at 1/8 in to 1/4 in per foot. Metal safety strips must be on top of any combustible hearth materials used for moisture management.

Drafts

• The fireplace should not be located in areas that create drafts (ie: frequently opened doors and central heating air inlets/outlets) that hamper the normal flow of air into the fire.

Gas Logs

• If you plan to install a gas log, the gas line should be installed before framing the fireplace.
• The gas line must be installed by a certified gas line installer.

Cleaning

There are three methods of cleaning the polished stainless steel of your outdoor fireplace;

1. Warm, soapy water – to loosen any dirt film
2. Glass cleaner with ammonia
3. Stainless steel cleaner available at hardware stores

Regardless of which method is used, remember that anything with too much abrasive may dull the finish.

Chimney Installations

Chimney Requirements – Offset Installations

Notes: G + H cannot exceed 20 feet.
Air Space Clearances: SK8 (2-wall) = 1¹⁄₂” and “S” Series (3-wall) = 2″

Illustration Key

The following safety rules apply to offset installations (letters correspond with illustration above):

• A. Height of the chimney is measured from the hearth to the chimney exit.
• B. Do not use more than 4 elbows per chimney.
  • Attach the straps of the return (top) elbow to a structural framing member.
  • The offset (first) elbow of any pair does not have straps.
• C. The chimney cannot be more than 30° (45° in Canada) from the vertical plane in any installation*.
• D. The maximum length of the angled run of the total chimney system is 20 feet. (G plus H cannot exceed 20 feet.)
• E. A chimney support (Model SKCS8) is required every 6 feet of angled run of chimney. Chimney supports are required for every 30 feet and 60 feet (SK8 pipe) or 20 feet and 40 feet (3-wall pipe) of vertical chimney height above the hearth.
  • Determine the offset distance of your chimney arrangement from the centerline of the fireplace to the centerline of the chimney where it is to pass through the first ceiling.
  • Note: This offset distance may not be your full offset distance. See Examples 2 and 3.

Planning Information

• Preplanning an installation is very important to ensure safety and to save time and money.
• An installer must predetermine where a fireplace will be set and how the chimney system will be run.

Moisture Resistance

• This outdoor fireplace will shed moderate amounts of water, but is not waterproof. Water and condensing water vapor may enter the chase under certain conditions.
• The fireplace will not perform as an exterior wall. Moisture penetration must be considered for construction that places the fireplace in structure walls or on moisture sensitive surfaces.
• When installed on exterior walls: MHSC recommends the fireplace chase be constructed outside the structure’s envelope. Where the platform meets the wall, use a flashing detail similar to that required for attached decks. Chase platforms, including hearths should slope away from the structure at 1/4 in per foot.
• The fireplace can be trimmed level.
• When installed on surfaces where water may collect or cause damage: MHSC recommends a slope of 1/8 in to 1/4 in per foot towards the drain port suggested. The fireplace can be shimmed level.
• Hearths should slope away from the front of the fireplace and chase at 1/8 in to 1/4 in per foot. Metal safety strips must be on top of any combustible hearth materials used for moisture management.

Mounting the Fireplace

A fireplace may only be mounted on the following surfaces:

1. A flat combustible surface.
2. A raised wooden platform.
3. A concrete block or other solid object placed beneath each of the four (4) corners of the fireplace.

The fireplace must be spaced 1/2″ (13 mm) from a combustible back wall and 1/2″ (13 mm) from a combustible side wall or support. (Fig. 21)

Planning the Chimney Run

Determine how the chimney will be run, length of run and chimney components required to complete the job. (Fig. 6) Never install a chimney below minimum heights.
In planning a chimney system, it is important to know:

1. The height of a chimney is measured from the hearth to the exit point on the termination.
2. A chimney cannot be offset more than 30° from a vertical plane.
3. A chimney may run straight up or it may be necessary to offset it to avoid obstructions.
4. The maximum length of an angled run (total chimney system) is 20′ (6 m).
5. No more than 2 offsets (4 total 30° elbows in U.S./or 2 total 45° elbows in Canada) per fireplace may be used.
6. A guy wire stabilizer is required for chimneys extending more than 6′ (1.8 m) above a roof line.

The Ten Foot Rule

Major U.S. building codes specify a minimum chimney height above the roof top. The “Ten Foot Rule” is a fire safety rule and not a draft rule. To ensure proper draft, it is recommended that you always meet or exceed the “Ten Foot Rule,” especially when installing a termination on a high pitch roof. (Fig. 9)

The key points of the “Ten Foot Rule” are:

1. If the horizontal distance from the chimney to the peak of the roof is 10′ (3 m) or less, the top of the chimney must be at least 2′ (610 mm) above the peak of the roof, but never less than 3′ (914 mm) in height above the highest point where it passes through the roof.
2. If a horizontal distance from the chimney to the peak of the roof is more than 10′ (3 m), a chimney height reference point is established on the surface of the roof a distance of 10′ (3 m) from the chimney in a horizontal plane. The top of the chimney must be at least 2′ (610 mm) above the reference point, but never less than 3′ (614 mm) in height above the highest point where it passes through the roof.

Chimney Supports

The chimney system is supported by the fireplace for vertical chimney heights less than 30′ (9 m) above the hearth. Chimney supports are required if the vertical height exceeds 30′ (9 m) with SK8 chimneys or 20′ (6 m) with 3-wall chimneys. Locate chimney supports at ceiling holes or other structural framing at 30′ (9 m) (SK8) or 20′ (6 m) (3-wall) heights. Spacing between chimney supports must not exceed 30′ (9 m) (SK8) or 20′ (6 m)(3-wall). Use Chimney Support Model SKCS8. (Note : The SKCS8 can not be mounted directly to the fireplace.) Support provided by elbow straps fulfills the support requirement only if they are spaced as previously described. (A chimney support is 2¹⁄₂” (64 mm) long when installed.)

Angled chimney runs require a support every 6′ (1.8 m) in addition to the elbow straps. Chimney supports are used for this function. (Fig. 10)

Chase Installation

• A chase is a vertical boxlike structure which encloses the fireplace and/or chimney. Chases are typically built on the outside of the house with fireplace opening cut into the outer wall of a room. (Fig. 5)
• If you need help in determining fireplace location or how the chimney system should be run, contact your MHSC dealer for assistance.

Installation

Insulating Fireplace Enclosure for Cold Climates

If you live in a cold climate, it is not required but highly recommended that you insulate fireplace enclosure to eliminate cold air penetration as much as possible.

Insulate base of fireplace with noncombustible insulation rated for a minimum of 300°F. Insulating is very important for outside wall installations over a concrete slab. If fireplace is installed on a platform, insulation should be placed on top of the platform before fireplace is set. (Fig. 11)

When a fireplace is installed in a chase or on an outside wall, enclosure should be treated like any outside wall in a home. Insulation should be installed on the inside wall as well as the outside wall(s). In a chase, it is also a good idea to install a firestop at the first ceiling level above the fireplace and enclose the chase with sheeting material. Insulation may then be installed above sheeting material to assure the spacearound the fireplace is totally protected. (Fig. 5) When installing the chimney, DO NOT caulk between outer pipe and firestop. It is vital that some air be allowed to flow through this very thin gap.

CAUTION

• WHEN INSTALLING A FIREPLACE IN AN INSULATED ENCLOSURE, BE SURE ALL REQUIRED AIR SPACES ARE MAINTAINED. (Fig. 21)

Framing

• Framing can be constructed before or after the fireplace is set in place, however, most installers build the frame before setting the fireplace.
• Frame fireplace with 2 x 4 lumber or heavier materials.
• Refer to framing dimensions in Figures 1, 2, 3 or 4 for basic fireplace specifications.

Note

• Framing should be positioned to accommodate wall covering and fireplace facing material.

Chimney Setup

Since you have already preplanned the chimney run, you should know exactly how the installation is to be accomplished — how much pipe is required, the number of elbows, if any, and type of termination to be used.

CAUTION: REPORT TO YOUR DEALERS ANY PARTS DAMAGED IN SHIPMENT, SPECIFICALLY CHECK THE END CONNECTION OF CHIMNEY SECTIONS AND ELBOWS.

NOTE: Fireplaces may use MHSC model SK8, or Model S (three wall) chimney systems. The ODSR Series “A” Fireplace will accept the SK8 chimney system as is; but a TWABR adapter collar is required when using the Model S (triple wall) chimney system. The installation procedure described in this manual applies only to the SK8 system. Either chimney system may be used, but may not be mixed.

Straight-Up Chimney Installation

• To mark the centerline of the flue, put the fireplace in final position and measure out from the wall: 9¹⁄₄” (235 mm).
• Mark a spot on the ceiling directly above the fireplace.
• Draw a line parallel to the back wall through this mark. (Fig. 12)
• Using a plumb bob positioned directly over center point of fireplace flue collar, mark the ceiling to establish the chimney center point. (Fig. 12)

Offset Installation

In order to clear an obstruction, it may be necessary to offset chimney from vertical. This is accomplished by using MHSC elbows. Use the 30° Offset Elbow table on to determine proper offset and parts required. Each offset requires two (2) elbows. The second elbow is equipped with support straps. It is very important to install the second elbow in each offset as close to the ceiling or support as possible so that the elbow straps can be secured to framing members to help support the weight of the chimney.

• Determine offset distance of your chimney arrangement from centerline of fireplace to the centerline of chimney where it is to pass through ceiling.
• Locate center point of the chimney on ceiling as though a straight up chimney arrangement is to be used. Measure your offset dimension from straight up chimney center point on ceiling.

Ceiling Chimney Hole/ Possible Obstructions

The size of the hole in ceiling will vary with the angle at which the chimney passes through ceiling. Drive a nail up through ceiling at marked chimney center point. Go to floor above and see where hole will becut. Check to see where existing ceiling joists and other possible obstructions are located…i.e. wiring, plumbing etc… If necessary, reposition chimney and/or fireplace to avoid obstructions.

Cutting the Hole

• Cover fireplace collar opening and cut proper sized chimney hole in chimney. The SK8 pipe allows you torun pipe through a typical 16” on center joist without cutting joists.

Framing the Ceiling Hole

• Frame the ceiling chimney hole as shown in Figure 14. It is good practice to use framing lumber that is the same size as the ceiling joists; this is a requirement at attic level.

The following table gives firestop spacer model numbers:

Size of Chimney

| Angle of Chimney at Ceiling

Fig. 13 Ceiling chimney hole sizes necessary for installing firestop spacer.

The inside dimension of the frame must be the same as the hole size selected from Figure 13 in order to provide required the 1¹⁄₂” (38 mm) of air space between the outside diameter of the chimney and the edges of the framed ceiling hole.

Positioning, Safety Strips, Securing the Fireplace

• Slide fireplace into position.
• Lift the fireplace front slightly and slide the metal safety strips under front bottom edge about 1¹⁄₂” (38 mm), allowing the remainder to extend in front of firebox. Over- lap strips at least 1/2″ (13 mm) to provide a positive joint. (Flat safety strips are packed with fireplace.) (Fig. 15)
• Safety strips are used to ensure that any combustible materials in front of the fireplace are protected even though a noncombustible hearth extension is required.
• If fireplace is to be elevated above the floor, a “Z” shaped metal safety strip must be fabricated and used to protect combustible surfaces in front of the fireplace.
• This “Z” shaped safety strip is not provided but must be fabricated of metal with each horizontal leg at least 1¹⁄₂” (38 mm) wide and equal in length to the metals strips provided with the fireplace.
• NOTE: Safety strips are not required over noncombustible floors where all supports at the base of the fireplace are noncombustible.
• Four (4) nailing flanges are incorporated on each corner of the surround. Bend the nailing flanges out, level the box, then secure it firmly in place by nailing the flanges to the framing members as shown in Figure 16.

Installing Outside Air Kit

An outside air kit is not installed in all ODSR Series “A” Fireplaces. If desired, or if local codes mandate the use of an air kit, then an AKU1 is required . If the outside air kit is to be used, the AKU1 MUST be installed BEFORE the fireplace is enclosed. Refer to the AKU1 instructions for field installation.

Installing the Chimney System

• Start by attaching the first chimney section to the collar on top of the fireplace.
• Install the pipe as pictured in Figure 17. When you get a good lock, you will hear the pipe clearly snap together. Once sections are snap-locked in place, it is extremely difficult to get them apart.
• Make sure the pipe is firmly snapped and locked together as each pipe section is mounted.
• When installing elbows, only outer pipe will snaplock.
• Middle pipes simply slide into position. Be sure to always attach straps on upper elbow to a structural framing member. (Fig. 18)
• Continue installing the pipe as required until pipe is installed up through the ceiling. At this point, you must install a firestop spacer.

Installing the Firestop Spacer in the Ceiling Hole

• A firestop spacer is used to keep pipe spaced properly and required for safety.
• Nail the firestop spacer (at each corner) to the framing members of the ceiling hole.
  • NOTE: A firestop spacer is not required at the roof.
• Hole sizes listed in Figure 13 for angled firestop spacers provide minimum required air space to chimney pipe for ceiling thickness up to 8″ (203 mm).
• When combined thickness of ceiling material, ceiling joists and flooring material exceeds 8″ (203 mm), adjustments must be made in framing to assure that minimum air spaces to the chimney are maintained.

Proper Firestop Spacer Installation

• Figure 19 shows different installation procedures for both an area that is an attic and an area that is not an attic.
• If the area above the ceiling is not an attic, position the firestop spacer with the flange on the ceiling side and the angled portion extending up into the hole.
• If the area above the ceiling is an attic, position the firestop spacer with the flange on the top of the framed hole and the angled portion extending down into the hole.
• Firestop spacers are not available for nor are they required on vertical walls.
• DO NOT put any sealant around the area where the outer pipe slides through the firestop spacer. If you seal this area, it may cause a fire hazard.

Canadian Requirements for Insulation Shield

• In Canada, an attic insulation shield is required to prevent attic insulation from contacting the chimney section.
• Framing dimensions for the chimney hole should measure 14¹⁄₂” x 14¹⁄₂” (368 x 368 mm). An attic shield MUST be installed on top of attic joists (above the floor level). (Fig. 20)
• Install the attic insulation shield with the flanges on its base extending down into the framing hole. Nail each corner of attic insulation shield to the framing membersof the ceiling hole using 8d nails. Attic shields are not required at the roof.

Continue Installing Pipe to Complete Run

• Continue attaching pipe sections to complete system to next level always being careful that the pipe is firmly snapped locked in place before proceeding to next pipe section.

Chimney Supports

If chimney supports are required, they are installed the same as elbows. Nail chimney support straps to adjacent structural framing, as shown on Figure 10. Bend straps as necessary and make sure they are secure so they will support the weight of the chimney. A chimney support is 2¹⁄₂” (64 mm) long when installed.
Consider this dimension when determining how many straight chimney sections are needed.

NOTE

• Chimney supports are generally used in long runs in a chase installation.

Additional Ceilings

• If you encounter additional ceilings, repeat same steps required for first ceiling installation. Refer to firestop illustration on Figure 19.

Penetrating the Roof

• Run pipe to roofline. Since chimney system must be vented to the out-of-doors, you must use an approved MHSC termination.
• If a chase is used, refer to the installation manual providedwith the termination cap.

Locate Chimney Centerpoint On Roof

• Use same procedure detailed in locating centerpoint of the flue system.
• Drive a nail up through roof at the center point. This will determine center point on outside of the roof.

Cut and Frame Roof Hole

• Size of roof hole varies with the type of chimney termination installed. Refer to installation instructions provided with MHSC chimney termination to find correct size of roof hole.
• There must be a 1¹⁄₂ (38 mm) air space between outermost portion of chimney sections and any adjacent combustible surfaces. (Combustible surfaces include burnable materials such as: ceiling members, joists, flooring, combustible insulation and roof structures.)
• WARNING: DO NOT PACK REQUIRED AIR SPACES WITH INSULATION OR OTHER MATERIALS.
• Mark an outline of the roof hole around the center of the point nail.
• NOTE: Hole dimensions given in the chimney top installation instructions are horizontal dimensions; therefore, the hole size must be marked on the roof accordingly.
• Cover the opening of the installed chimney so debris cannot get into the system.
• Cut and frame the hole. It is good practice to use framing lumber that is the same size as the rafters. Install the frame securely because the chimney top and flashing anchored to the frame must be able to withstand heavy winds.

Install Remainder of Chimney Sections

• Since you have already preplanned the height of your termination according to the Ten Foot Rule, continue to install pipe to the predetermined height.
• Check the chimney top installation instructions fordetails on how high above the roof top the chimney sections (all pipes) should extend.

Installing Top Housing or Termination

• Follow the installation instructions provided with the chimney termination you have selected.

Installing Chimney In a Chase

• Refer to Figure 5 for an illustration of a typicalchase installation.
• CAUTION: Treatment of firestop spacers and construction of chase may vary with type of building.
• These instructions are not a substitute for local building codes. You must check your local building codes to determine specific requirements for your city or state.

NOTE

• Other building materials may be required in addition to MHSC Firestop Spacers.

Finishing

CAUTION: All joints between the finished wall and the fireplace surround (top/sides) must be sealed with non-combustible material to prevent cold air leakage into the room. Only noncombustible material may be applied to the facing of the fireplace surround. (Black painted area) (Fig. 21)

Finish Wall

• Finish the wall with material of your choice. Do not install a combustible mantel shelf less than 12″ (305 mm) from the top of the fireplace opening. Donot install a mantel face plate less than 6″ (159 mm) from top of fireplace opening. (Fig. 23).
• If a combustible material is used below a flat mantel shelf, consult your local building codes for minimum clearance from top of fireplace opening to bottom of mantel shelf.
• All joints (top, bottom and sides) where wall or decorative facing material meets fireplace surround must be completely sealed with a noncombustible material. (Figs. 22 and 23)

NOTE: No side wall protection is required for fireplaces installed at 45° to two (2) side walls (corner installation).
Often a decorative surround or vertical portion of the mantel is desired. If this is constructed of any combustible material it must be within the safe zone indicated in Figure 24.

Side Wall Protection

Adjacent combustible side walls that are within the minimum dimensions shown in Figure 24 of fireplace opening must be protected with MHSC Wall Shield Model SP40 or a specifically built wall shield described below.
The special wall shield design described in Figure 20 is an alternate method of adding protection to side walls and can be used in place of the SP40 with the same wall clearances specified for the SP40. Rt must =1.85 minimum.

Examples of wall shield insulation:

1. Manville – CERAFORM 126, K=.27, 1/2 inches thick
2. MHSC – EH2416, K = .458, 1 inch thick required.

Hearth Installation

A hearth extension is required to protect a combustible floor in front of the fireplace. Refer to Figure 24 for minimum dimensions and mounting detail.

NOTE: Hearth Extension must not cover the air inlet opening of a fireplace.

The hearth extension described in Figure 24 must be a durable noncombustible material with a minimum (total) Rt value of 1.09; refer to Figure 25 for examples. The overall height (above a combustible floor), depth and width must be as indicated, with the extension centered to the fireplace opening.

The top of insulation must be covered with a noncombustible decorative covering or a piece of .018” minimum sheet metal, to protect hearth extension material. (Fig. 24) Secure the hearth extension to the floor to prevent shifting, using trim molding or other similar means at three (3) outer edges. Seal crack between the fireplace hearth and hearth extension with noncombustible material. (Figs. 24 and 26)

COMMON MATERIALS AND FACTORS

WARNING: HEARTH EXTENSION MUST BE INSTALLED IN ACCORDANCE WITH FIGURE 25 AND MUST NOT COVER THE BOTTOM FRONT OPENING OF THE CIRCULATING MODEL.

Alternate noncombustible materials may be used providing the (total) thermal resistance (Rt value) of the alternate material employed is greater than or equal to R= 1.09. Thermal resistance (R) or thermal conductivity (K), may be obtained from manufacturer of the material.

• Factors are related by the formula K = 1/R.
• T = given thickness
• R = thermal resistance for a given thickness (T)
• K = thermal conductivity

Noncombustible material with a lower R value may be used, provided thickness of material is sufficiently greater to maintain an equivalent (total) thermal resistance (Rt).

Example of Determining Hearth Extension Equivalents

To determine the thickness required for any new material:

Example for Common Brick

• T (new) = 5.0/0.458 x 0/50 in. = 5.46 in. (new required thickness).

Installing Line for Gas Logs

• MHSC fireplaces are designed to accept a 1/2″ (13 mm) gas line for installation of an approved gas appliance.
• (MHSC manufactures a wide variety of gas logs for use in MHSC Fireplaces.)
• Be sure to have the appliance installed in accordance with building codes.
• Gas connection may enter from either left or right side of the fireplace.
• Locate appropriate gas line in the outer casing of fireplace and remove insulation from gas line tube. (Fig. 27)
• From inside the fireplace, locate the knockout on the firebrick — be sure you are on the appropriate or “gas line” side of the fireplace. Using a flat bladed screwdriver or small chisel and hammer, carefully tap around the knockout until it loosens and falls out.
• Install 1/2″ (13 mm) certified gas pipe through opening.
• After gas pipe installation is complete, use insulation that was removed from gas line tube to repack space around the pipe. Material should be inserted from outside of the fireplace and packed tightly to totally seal between the pipe and tube.
• NOTE: Gas pipe should not come in contact with any wood structures until it has reached a point at least one (1) inch away from fireplace side.
• NOTE: When installing an ANSI Z21.11.2 ventless appliance the finishing material used for the mantel must be rated at 250°F or greater.
• BTU input of a gas appliance installed in fireplace should be rated less than 100,000 BTU/Hr.
• Gas pipe installation is intended for connection to a decorative gas appliance only when (1.) incorporating an automatic shutoff device and (2.) complying with the Standard for Decorative Gas Appliances for Installation in Vented Fireplaces (ANSI Z21.60) or
• Gas-Fired Log Lighters for Woodburning Fireplaces.
• Decorative gas appliance should be installed in accordance with the National Fuel Gas Code, ANSI Z223.1/ NFPA 54 (latest edition).

CAUTION: WHEN USING DECORATIVE GAS APPLIANCE, FLUE DAMPER MUST BE SET IN FULLY OPEN POSITION. IF YOU HAVE GLASS DOORS ON THE FIREPLACE, THEY MUST ALSO BE FULLY OPENED.
WARNING: DO NOT OPERATE AN UNVENTED GAS LOG SET IN THIS FIREPLACE WITH THE CHIMNEY REMOVED.
WARNING: WHEN INSTALLING AN UNVENTED AS LOG SET, THE MHSC MODEL CABL OR CABR 4″ ADJUSTABLE HOOD MUST BE USED.

If installing an unvented gas log set, refer to statement below:

• Only unvented gas logsets which have been found to comply with the Standard for Unvented Room Heaters, ANSI Z21.11.2, are to be installed in this fireplace.
