WATER VAPOR: A BY-PRODUCT OF UNVENTED ROOM HEATERS
Water vapor is a by-product of gas combustion. An unvented room heater produces approximately one (1) ounce (30 mL) of water for every 1,000 BTUs (.3 Kw) of gas input per hour. An unvented room heater is intended as a supplemental heater rather than a primary heat source. In most supplemental heat applications, the water vapor does not create a problem.
In most applications, the water vapor enhances the low humidity atmosphere experienced during cold weather.
The following steps will help ensure that water vapor does not become a problem:

1. Be sure the heater is the proper size for the application, including adequate combustion air and circulation air.
2. If there is high humidity, a dehumidifier may be used to help lower the water vapor content of the air.
3. Do not use an unvented room heater as the primary heat source.

AIR FOR COMBUSTION AND VENTILATION
CAUTION: This heater shall not be installed in a room or space unless the required volume of indoor combustion air is provided by the method described in the National Fuel Gas Code, ANSI Z223.1/NFPA54, the International Fuel Gas Code, or applicable local codes.
PRODUCING ADEQUATE VENTILATION
All spaces in homes fall into one of the three following ventilation classifications:

1. Unusually Tight Construction
2. Unconfined Space
3. Confined Space
   The information on pages 8 through 10 will help you classify your space and provide adequate ventilation.

Confined and Unconfined Space
A confined space as a space whose volume is less than 50 cu. ft. per 1,000 BTU/hr (4.8 m^3 per kw) of the aggregate input rating of all appliances installed in that space and an unconfining space as a space whose volume is not less than 50 cu. ft. per 1,000 BTU/hr (4.8 m^3 per kw) of the aggregate input rating of all appliances installed in that space. Rooms connecting directly with the space in which the appliances are installed*, through openings not furnished with doors, are considered a part of the unconfined space.
This heater shall not be installed in a confined space or unusually tight construction unless provisions are provided for adequate combustion and ventilation air.

• Adjoining rooms are connecting only if there are doorless passageways or ventilation grills between them.

Unusually Tight Construction
The air that leaks around doors and windows may provide enough fresh air for combustion and ventilation. However, in buildings of unusually tight construction, you must provide additional fresh air. Unusually tight construction is defined as construction where:
a) walls and ceilings exposed to the outside atmosphere have a continuous water vapor retarder with a rating of one perm (6×10-11kg per pa-sec-m2) or less with openings gasketed or sealed and
b) weather stripping has been added on windows that can be opened and on doors and
c) caulking or sealants are applied to areas such as joints around window and door frames, between sole plates and floors, between wall-ceiling joints, between wall panels, at penetrations for plumbing, electrical, and gas lines, and at other openings.
If your home meets all of the three criteria above, you must provide additional fresh air.
See “Ventilation Air From Outdoors” (page 10). If your home does not meet all of the three criteria above, proceed to “Determining Fresh-Air Flow For Heater Location”.

DE TERMINING FRESH-AIR FLOW FOR HEATER LOCATION
Determining if You Have a Confined or Unconfined Space
Use this worksheet to determine if you have a confined or unconfined space.
Space: Includes the room in which you will install heater plus any adjoining rooms with doorless passageways or ventilation grills between the rooms.

1. Determine the volume of the space Length × Width × Height = cu. ft. (volume of space) Example: Space size 20 ft. (length) × 16 ft.(width) × 8 ft. (ceiling height) = 2560 cu. ft. (volume of space)
   If additional ventilation to adjoining room is supplied with grills or openings, add the volume of these rooms to the total volume of the space.

2. Divide the space volume by 50 cu. ft. to determine the maximum BTU/hr the space can support.
   ___ (volume of space) ÷ 50 cu. ft.= (Maximum BTU/hr the space can support)
   Example: 2560 cu. ft. (volume of space) ÷ 50 cu. ft. = 51.2 or 51,200 (maximum BTU/hr the space can support)

3. Add the BTU/hr of all fuel burning appliances in the space.
   Vent-free heater BTU/hr
   Gas water heater* ____BTU/hr
   Gas furnace ____BTU/hr
   Vented gas heater ____BTU/hr Example:
   Gas heater logs __BTU/hr Gas water heater 30,000 BTU/hr
   Other gas appliances+ BTU/hr Vent-free heater + 26,000 BTU/hr
   Total = BTU/hr Total = 56,000 BTU/hr
   Do not include direct-vent gas appliances. Direct-vent draws combustion air from the
   outdoors and vents to the outdoors.
   4. Compare the maximum BTU/hr the space can support with the actual amount of BTU/hr used.
   BTU/hr (maximum the space can support)
   BTU/hr (actual amount of BTU/hr used).
   Example : 51,200 BTU/hr (maximum the space can support) 56,000 BTU/hr (actual amount of BTU/hr used)
   The space in the above example is a confined space because the actual BTU/hr used is more than the maximum BTU/hr the space can support.
   You must provide additional fresh air. Your options are as follows:
   a) Rework worksheet, adding the space of an adjoining room. If the extra space provides an unconfined space, remove door to adjoining room or add ventilation grills between rooms. See “Ventilation Air From Inside Building,” page 10.
   b) Vent room directly to the outdoors. See “Ventilation Air From Outdoors”, page 10.
   c) Install a lower BTU/hr heater if lower BTU/hr size makes room unconfined. If the actual BTU/hr used is less than the maximum BTU/hr the space can support, the space is an unconfined space.
   You will need no additional fresh air ventilation.

Ventilation Air From Inside Building
This fresh air would come from adjoining unconfined space. When ventilating to an adjoining unconfined space, you must provide two permanent openings: one within 12 in. of the wall connecting the two spaces (see options 1 and 2, Fig. 1). You can also remove door into adjoining room (see option 3, Fig. 1).
Follow the National Fuel Gas Code NFPA 54/ANS Z223.1. Air for Combustion and Ventilation for required size of ventilation grills or ducts.

Ventilation Air From Outdoors
Provide extra fresh air by using ventilation grills or duct. You must provide two permanent openings: one within 12 in. of the ceiling and one within 12 in. of the floor.
Connect these items directly to the outdoors or spaces open to the outdoors. These spaces include attics and crawl spaces.
Follow the National Fuel Gas Code NFPA 54/ANS Z223.1. Air for Combustion and Ventilation for required size of ventilation grills or ducts.
IMPORTANT: Do not provide openings for inlet or outlet air into attic if attic has a thermostat-controlled power vent. Heated air entering the attic will activate the power vent. Rework worksheet, adding the space of the adjoining unconfined space. The
combined spaces must have enough fresh air to supply all appliances in both spaces.

Before cutting, drilling or hammering verify their location. If needed, contact your electrician, plumber or service person.
Use only the last hole on each end of mounting bracket to attach bracket to wall. Attach mounting bracket to a wall only in one of two ways:

1. Attaching to wall stud: This method provides the strongest hold. Insert wood screws (ST.8*45-16) through mounting bracket and into wall studs.
2. Attaching to expansion bracket: This method allows you to attach mounting bracket to hollow walls (wall areas between studs) or to solid walls (concrete or masonry).
   Decide which method better suits your needs. Either method will provide a secure hold for the mounting bracket.

Marking Screw Locations

1. Tape mounting bracket to wall where heater will be located. Make sure mounting bracket is level.

2. Mark screw locations on wall (See Fig. 16).
   Note: Mark only last hole on each end of mounting bracket. Insert (2) wood screws (ST.8*45-16) total through these holes only.

3. Remove tape and mounting bracket from wall.

Attaching Mounting Bracket To Wall
Note: Expansion bracket, wood screws (ST.8*45-16), and wall hanging spacers are in hardware package.
The hardware package is provided with heater.
Attaching to Wall Stud Method
For attaching mounting bracket to wall studs:

1. Drill holes at marked locations using 9/64-inch drill bit.
2. Place mounting bracket onto wall. Line up last hole on each end of bracket with holes drilled in wall.
3. Insert wood screws (ST.8*45-16) through bracket and into wall studs.
4. Tighten wood screws (ST.8*45-16) until mounting bracket is firmly fastened to wall studs.
5. Check that the bracket is secure before mounting heater!

Attaching to Expansion Bracket Method
For attaching mounting bracket to hollow walls (wall areas between studs) or solid walls (concrete or masonry):

1. Drill holes at marked locations using 5/16-inch drill bit.
   For solid walls (concrete or masonry), drill at least 1 inch deep.

2. Fold wall expansion bracket as shown in (See Fig. 17).

3. Insert wall expansion bracket (wings first) into hole. Tap expansion bracket flush to wall.

4. For thin walls (1/2 inch or less), insert expansion bracket tool into expansion bracket. Push expansion bracket tool to “pop” open expansion bracket wings (See Fig. 18). IMPORTANT: Do not hammer expansion bracket tool!
   For thick walls (over 1/2 inch thick) or solid walls, do not pop open wings.

5. Place mounting bracket onto wall. Line up last hole on each end of bracket with expansion bracket.

6. Insert expansion bracket screws (ST4.8*15-16) through wall mounting bracket and into expansion brackets.

7. Tighten expansion bracket screws (ST4.8*15-16) until mounting bracket is firmly fastened to wall.

8. Check that the bracket is secure before mounting heater!

Attaching Wall Hanging Spacers to Heater
WARNING: Failure to properly install the wall hanging spacers may result in property damage, personal injury or even death.

1. Locate spacer mounting holes on the lower right/left sections of the heater back panel.
2. Secure (2) wall hanging spacers to heater back panel using (2) wall hanging spacer screws (M4*25) (See Fig. 19a).

Placing Heater On Mounting Bracket

1. Locate two horizontal slots on back panel of heater.
2. Place heater onto mounting bracket. Slide horizontal slots onto stand-out tabs on mounting bracket. Be sure spacers rest evenly against wall (See Fig. 19b).

CONNECTING TO GAS SUPPLY
WARNING: A qualified service technician must connect heater to gas supply. Follow all local codes.
IMPORTANT: This appliance requires a 3/8-inch NPT (National Pipe Thread) inlet connection to the pressure regulator. Never connect the heater to private (non-utility) gas wells, commonly known as wellhead gas.
WARNING: Do not overtighten gas connections.
CAUTION: Use only new, black iron or steel pipe. Internally tinned copper tubing may be used in certain areas. Check your local codes. Use pipe of 1/2-in. diameter or greater to allow proper gas volume to heater. If pipe is too small, undue loss of pressure will occur.
CAUTION: Check your gas line pressure before connecting heater to gas line. Gas line pressure must be a minimum 6” WC for NG & 11″ WC for LP with a max pressure of 9” WC for NG & 14″ WC for LP. If gas line pressure is higher, the unit will not work and heater regulator damage could occur.
CAUTION: Never connect heater directly to an LP supply. This heater requires an external regulator (not supplied). Install the external regulator between the heater and gas supply.
CAUTION: Avoid damage to regulator. Hold gas regulator with wrench when connecting into gas piping and/or fittings.
CAUTION: Use pipe joint sealant that is resistant to gas (Propane or Natural Gas).

Typical Inlet Pipe Diameters
Use 3/8-inch black iron pipe or greater. Installation must include an equipment shutoff valve, union, and plugged 1/8-inch NPT tap.
Locate NPT tap within reach for test gauge hook up. NPT tap must be upstream from heater (see Fig. 20).
IMPORTANT: Install an equipment shutoff valve in an accessible location. The equipment shutoff valve is for turning on or shutting off the gas to the appliance.
Apply pipe joint sealant lightly to male threads. This will prevent excess sealant from going into pipe. Excess sealant in pipe could result in clogged heater valves.

Install sediment trap in supply line as shown (See Fig. 20). Place sediment trap where it is within reach for cleaning. Place sediment trap where trapped matter is not likely to freeze. A sediment trap traps moisture and contaminants.
This keeps them from going into heater controls.
If sediment trap is not installed or is installed wrong, heater may not run properly.

CHECKING GAS CONNECTIONS

WARNING: Test all gas piping and connections for leaks after installing or servicing. Correct all leaks immediately.
WARNING: Never use an open flame to check for a leak. Apply a 50/50 mixture of liquid soap and water to all joints. If bubbles form, there may be a leak. Correct all leaks immediately.
Pressure Testing Gas Supply Piping System
Test Pressures In Excess Of 1/2 PSIG ( 3.5kPa )

THERMOSTATIC CONTROL OPERATION (SELECT MODELS)
The thermostat used on this heater senses the room temperature. At times the room may exceed the set temperature. If so, the burner will shut off.
The burner will cycle back on when room temperature drops below the set temperature. The control knob can be set to any comfort level between “HIGH” (5) and “LOW”(1) (See Fig. 25).

MANUAL CONTROL OPERATION
Manual valves remain burning in the desired setting until manually turned to OFF ” “(See Fig. 25).
INSPECTING BURNERS
Check pilot flame pattern daily when in use and at least yearly by a qualified service agency.
PILOT FLAME PATTERN
Fig. 26 shows a correct pilot flame pattern. Fig. 27 shows an incorrect pilot flame pattern. The incorrect pilot flame is not touching the thermocouple. This will cause the thermocouple to cool, which shuts the heater off.
If pilot flame pattern is incorrect:

• turn heater off (see “To Turn Off Gas to Appliance” on page 19)
• see Troubleshooting pages 23 through 26.

BURNER FLAME PATTERN
Fig. 28 shows a correct burner flame pattern. Fig. 29 shows an incorrect burner flame pattern with lifting, and excessive flame height.
If burner flame is incorrect:

• turn heater off (see “To Turn Off Gas to Appliance”, page 20).
• see Troubleshooting, pages 23 through 26.

NOTE: Ambient flame burners produce both a blue and yellow flame. An excessively high yellow colored flame may be caused by airborne dust, dander, pet hair, etc. Additionally, an excess amount of Mercaptane in the fuel can result in an orange or yellow colored flame.
When this heater is set for use on propane gas, the upper one third of the flame may be bright yellow.
When this heater is set for use on natural gas, a slight yellow tipping of the flame may occur.

CARE AND MAINTENANCE

NOTE: Before servicing you will need to remove the front panel of the heater. There are 4 Philips head screws, 2 on the left side and 2 on the right, securing the front panel to the heater (See Fig. 30). Always allow the unit to cool for at least thirty minutes before attempting to remove the front panel. WARNING: Turn off heater, unplug electrical cord and let cool before servicing.

CAUTION: You must keep control areas, burner, and circulating air passageways of heater clean. Inspect these areas of heater before each use. Have heater inspected yearly by a qualified service person. Heater may need more frequent cleaning due to excessive lint from carpeting, bedding material, pet hair, etc.
WARNING: Failure to keep the primary air opening(s) of the burner(s) clean may result in sooting and propery damage.

CLEANING ODS/PILOT AND BURNER
Use a vacuum cleaner, pressurized air, or a small, soft bristled brush to clean burner ports, orifice and primary burner. Look into burner opening and ensure that it is clean.
CLEANING BURNER PILOT AIR INLET HOLE
We recommend that you clean the unit every three months or after 2,500 hours of operation. We also recommend that you keep the burner tube and pilot assembly clean and free of dust and dirt. To clean these parts we recommend using compressed air no greater than 30 PSI. You can use a vacuum cleaner in the blow position. If using compressed air in a can, please follow the directions on the can.
If you don’t follow directions on the can, you could damage the pilot assembly.
CAUTION: Never use a wire, needle, or similar object to clean ODS/pilot. This can damage ODS/ pilot unit.

1. Shut off the unit, including the pilot. Allow the unit to cool for at least thirty minutes.
2. Remove 4 screws – 2 screws on each side of the front panel.
3. Pull front panel forward.
4. Blow air through the ports/slots and holes in the burner. Also clean the pilot assembly. A yellow tip on the pilot flame indicates dust and dirt in the pilot assembly. There is a small pilot air inlet hole about two inches from where the pilot flame comes out of the pilot assembly (see Fig. 26 & 27 on page 19). With the unit off, lightly blow air through the air inlet hole. You may blow through a drinking straw if air is not available.
5. Replace front panel when completed, using the screws removed.

CLEANING CABINET AIR PASSAGEWAYS
Use a vacuum cleaner or pressurized air to clean.
CLEANING FAN (Select Models)
Carefully use a vacuum cleaner or compressed air to keep fan compartment and blades free of dust and debris.
NOTE: The fan motor is pre-lubricated for extended bearing life and requires no further lubrication.
CLEANING EXTERIOR
Use a soft cloth dampened with a mild soap and water mixture.
Wipe the cabinet to remove dust.
