SAFETY INFORMATION
WARNINGS
IMPORTANT: Read this owner’s manual carefully and completely before trying to assemble, oper­ate, or service this heater. Im­proper use of this heater can cause serious injury or death from burns, fire, explosion, electrical shock, and carbon monoxide poisoning.
DANGER: Carbon monoxide
poisoning may lead to death!
Carbon Monoxide Poisoning: Early signs
of carbon monoxide poisoning resemble the flu, with headaches, dizziness, or nau­sea. If you have these signs, the heater may not be working properly. Get fresh air at once! Have heater serviced. Some people are more affected by carbon monoxide than others. These include pregnant women, people with heart or lung disease or ane­mia, those under the influence of alcohol, and those at high altitudes.
Propane/LP Gas: Propane/LP gas is odor-
less. An odor-making agent is added to pro­pane/LP gas. The odor helps you detect a propane/LP gas leak. However, the odor added to propane/LP gas can fade. Propane/LP gas may be present even though no odor exists.
Make certain you read and understand all warnings. Keep this manual for reference. It is your guide to safe and proper operation of this heater.
WARNING: Any change to this heater or its controls can be dangerous.
WARNING: Do not allow fans to blow directly into the heater. Avoid any drafts that alter burner flame patterns. Ceiling fans can create drafts that alter burner flame patterns. Altered burner patterns can cause sooting.

AIR FOR COMBUSTION AND VENTILATION
WARNING: This heater shall not be installed in a confined space or unusually tight construction unless provisions are provided for adequate combustion and ven­tilation air. Read the following in­structions to insure proper fresh air for this and other fuel-burning appliances in your home.
Today’s homes are built more energy effi­cient than ever. New materials, increased insulation, and new construction methods help reduce heat loss in homes. Home owners weather strip and caulk around windows and doors to keep the cold air out and the warm air in. During heating months, home owners want their homes as airtight as possible.
While it is good to make your home energy efficient, your home needs to breathe. Fresh air must enter your home. All fuel-burning appliances need fresh air for proper com­bustion and ventilation.
Exhaust fans, fireplaces, clothes dryers, and fuel burning appliances draw air from the house to operate. You must provide ad­equate fresh air for these appliances. This will insure proper venting of vented fuel­burning appliances.
PROVIDING ADEQUATE VENTILATION
The following are excerpts from National Fuel Gas Code, NFPA 54/ANS Z223.1, Sec­tion 5.3, Air for Combustion and 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 5 through 7 will
help you classify your space and provide adequate ventilation.
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 x 10 per pa-sec-m2) or less with open­ings gasketed or sealed
b. weather stripping has been
added on openable windows and doors
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
From Outdoors
If your home does not meet all of the three criteria above, proceed to
and

Confined and Unconfined Space
The National Fuel Gas Code ANS Z223.1 defines a confined space as a space whose volume is less than 50 cubic feet per 1,000 Btu per hour (4.8 m3 per kw) of the aggre­gate input rating of all appliances installed in that space and an unconfined space as a space whose volume is not less than 50 cubic feet per 1,000 Btu per hour (4.8 m3 per kw) of the aggregate input rating of all appliances installed in that space. Rooms communicating 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 communicating only if there are doorless passageways or ventila­tion grills between them.

DETERMINING 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 x width x height). Length x Width x Height = _________________cu. ft. (volume of space)
Example:
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 cubic feet to determine the maximum Btu/Hr the space can support.
_____________________(volume of space) ÷ 50 cu. ft. = (Maximum Btu/Hr the space can support)
Example:
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 Gas fireplace logs _____________________ Btu/Hr Other gas appliances* + _____________________ Btu/Hr Total = _____________________ 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:
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 adjoin-
ing room or add ventilation grills between rooms. See Ventilation Air From Inside Building, page 7.
B. Vent room directly to the outdoors. See Ventilation Air From Outdoors, page 7. 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.
Space size 20 ft. (length) x 16 ft. (width) x 8 ft. (ceiling height) = 2560 cu. ft. (volume of space)
2560 cu. ft. (volume of space) ÷ 50 cu. ft. =51.2 or 51,200 (maximum Btu/Hr the space can support)
Example:
Gas water heater 30,000 Btu/Hr Vent-free heater + 30,000 Btu/Hr Total = 60,000 Btu/Hr
51,200 Btu/Hr (maximum the space can support) 60,000 Btu/Hr (actual amount of Btu/Hr used)
WARNING: If the area in which the heater may be operated is smaller than that defined as an unconfined space or if the building is of unusually tight construction, provide adequate combustion and ventilation air by one of the methods described in the
National Fuel Gas Code, ANS Z223.1, Section 5.3

This fresh air would come from an adjoining unconfined space. When ventilating to an adjoining unconfined space, you must pro­vide two permanent openings: one within 12" of the ceiling and one within 12" of the floor on the wall connecting the two spaces (see options 1 and 2, Figure 8). You can also remove door into adjoining room (see op­tion 3, Figure 8). Follow the National Fuel
Gas Code, NFPA 54/ANS Z223.1, Section
5.3, Air for Combustion and Ventilation for
required size of ventilation grills or ducts.
OWNER’S MANUAL
WARNING: 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.
Ventilation Air From Outdoors
Provide extra fresh air by using ventilation grills or ducts. You must provide two per­manent openings: one within 12" of the ceiling and one within 12" 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, Section 5.3, Air for Combustion and Ventilation for required size of ventilation
grills or ducts.
IMPORTANT:

CONNECTING TO GAS SUPPLY
WARNING: This appliance re­quires a 3/8" NPT (National Pipe Thread) inlet connection to the pressure regulator.
WARNING: A qualified service person must connect heater to gas supply. Follow all local codes.
CAUTION: Never connect heater directly to the propane/LP supply. This heater requires an ex­ternal regulator (not supplied). In­stall the external regulator between the heater and propane/LP supply.
The installer must supply an external regu­lator. The external regulator will reduce incoming gas pressure. You must reduce incoming gas pressure to between 11 and 14 inches of water. If you do not reduce incom­ing gas pressure, heater regulator damage could occur. Install external regulator with the vent pointing down as shown in Figure
20. Pointing the vent down protects it from freezing rain or sleet.
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" or greater diameter to allow proper gas volume to heater. If pipe is too small, undue loss of pressure will occur.
Installation must include a equipment shutoff valve, union, and plugged 1/8" NPT tap. Locate NPT tap within reach for test gauge hook up. NPT tap must be upstream from heater (see Figure 21).
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.
Pressure Regulator
3/8" NPT Pipe Nipple
CAUTION: Use pipe joint seal­ant that is resistant to liquid pe­troleum (LP) gas.
We recommenc that you install a sediment trap in supply line as shown in Figure 21. Locate sediment trap where it is within reach for cleaning. Install in piping system between fuel supply and heater. Locate 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.
IMPORTANT:
Hold pressure regulator with wrench when connecting it to gas piping and/or fittings.

THERMOSTAT
CONTROL
OPERATION
The thermostatic control used on this heater differs from standard thermostats. Standard thermostats simply turn on and off the burner. The thermostat used on this heater senses the room temperature. The thermostat adjusts the amount of gas flow to the burner. This increases or de­creases the burner flame height. 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 heat level between HI and LO.
Note:
The thermostat sensing bulb mea­sures the temperature of air near the heater cabinet. This may not always agree with room temperature (depending on housing construction, installation loca­tion, room size, open air temperatures, etc.). Frequent use of your heater will let you determine your own comfort levels.
MANUAL LIGHTING
PROCEDURE
1. Remove front panel (see Figure 2,
page 4).
2. Follow steps 1 through 5 under Light-
ing Instructions, page 14.
3. With control knob pressed in, strike
match. Hold match to pilot until pi­lot lights.
4. Keep control knob pressed in for 30
seconds after lighting pilot. After 30 seconds, release control knob. Now follow step 8 under Lighting Instruc- tions, page 14.
5. Replace front panel.
INSPECTING BURNER
Check pilot flame pattern and burner flame pattern often.
PILOT FLAME PATTERN
Figure 26 shows a correct pilot flame pat­tern. Figure 27 shows an incorrect pilot flame pattern. The incorrect pilot flame is not touching the thermocouple. This will cause the thermocouple to cool. When the thermocouple cools, the heater will shut down.
If pilot flame pattern is incorrect, as shown in Figure 27
• turn heater off (see To Turn Off Gas to Appliance, page 14)
• see Tr oubleshooting, pages 17 through 19

BURNER FLAME PATTERN
Figure 28 shows a correct burner flame pattern. Figure 29 shows an incorrect burner flame pattern. The incorrect burner flame pattern shows yellow tipping of the flame. It also shows the flame higher than one inch above the log.
Note:
When using the heater the first time, the flame will be yellow for approximately one hour until the log cures.
WARNING: If yellow tipping
occurs, your heater could pro­duce increased levels of carbon monoxide. If burner flame pat­tern shows yellow tipping, follow instructions at bottom of this page.
NOTICE: Do not mistake orange flames with yellow tipping. Dirt or other fine particles enter the heater and burn causing brief patches of orange flame.
If burner flame pattern is incorrect, as shown in Figure 29
• turn heater off (see To Turn Off Gas to
Appliance, page 14)

CLEANING AND MAINTENANCE
WARNING: Turn off heater
and let cool before cleaning.
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, pet hair, bedding material, etc.
CLEANING BURNER INJECTOR HOLDER AND PILOT AIR INLET HOLE
The primary air inlet holes allow the proper amount of air to mix with the gas. This pro­vides a clean burning flame. Keep these holes clear of dust, dirt, lint, and pet hair. Clean these air inlet holes prior to each heating season. Blocked air holes will create soot. We recommend that you clean the unit every three months of during operation and have heater inspected yearly by a qualified service person.
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. Your local computer store, hard­ware store, or home center may carry com­pressed air in a can. 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.
1. Shut off the unit, including the pilot. Allow the unit to cool for at least thirty minutes.
2. Inspect burner, pilot, and primary air inlet holes on injector holder for dust and dirt (see Figure 30).
3. Blow air through the ports/slots and holes in the burner.
4. Check the injector holder located at the end of the burner tube again. Remove any large particles of dust, dirt, lint, or pet hair with a soft cloth or vacuum cleaner nozzle.
5. Blow air into the primary air holes on the injector holder.
6. In case any large clumps of dust have now been pushed into the burner repeat steps 3 and 4.
Clean the pilot assembly also. 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 Figure 31). With the unit off, lightly blow air through the air inlet hole. You may blow through a drinking straw if compressed air is not available.

LIMITED WARRANTY
COMFORT GLOW VENT-FREE RESIDENTIAL GAS HEATERS
DESA International warrants this product to be free from defects in materials and components for two (2) years from the date of first purchase, provided that the product has been properly installed, operated and maintained in accordance with all applicable instructions. To make a claim under this warranty the Bill of Sale or cancelled check must be presented.
This warranty is extended only to the original retail purchaser. This warranty covers only the cost of part(s) required to restore this heater to proper operating condition. Warranty part(s) MUST be obtained through authorized dealers of this product and/or DESA International who will provide original factory replacement parts. Failure to use original factory replacement parts voids this warranty. The heater MUST be installed by a qualified installer in accordance with all local codes and instructions furnished with the unit.
This warranty does not apply to parts that are not in original condition because of normal wear and tear, or parts that fail or become damaged as a result of misuse, accidents, lack of proper maintenance or defects caused by improper installation. Travel, diagnostic cost, labor, transportation and any and all such other costs related to repairing a defective heater will be the responsibility of the owner.
TO THE FULL EXTENT ALLOWED BY THE LAW OF THE JURISDICTION THAT GOVERNS THE SALE OF THE PRODUCT; THIS EXPRESS WARRANTY EXCLUDES ANY AND ALL OTHER EXPRESSED WARRANTIES AND LIMITS THE DURATION OF ANY AND ALL IMPLIED WARRANTIES, INCLUDING WARRANTIES OF MERCHANTA­BILITY AND FITNESS FOR A PARTICULAR PURPOSE TO TWO (2) YEARS FROM THE DATE OF FIRST PURCHASE; AND DESA INTERNATIONAL’S LIABILITY IS HEREBY LIMITED TO THE PURCHASE PRICE OF THE PRODUCT AND DESA INTERNATIONAL SHALL NOT BE LIABLE FOR ANY OTHER DAMAGES WHATSOEVER INCLUDING INDIRECT, INCIDENTAL OR CONSEQUENTIAL DAMAGES.
Some states do not allow a limitation on how long an implied warranty lasts or an exclusion or limitation of incidental or consequential damages, so the above limitation on implied warranties, or exclusion or limitation on damages may not apply to you.
This warranty gives you specific legal rights, and you may also have other rights that vary from state to state. For information about this warranty write:
