Electronic Ignition System This heater has an electronic ignitor to light heater fuel supply. www.desatech.com 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 fuel-burning appliances. PROVIDING ADEQUATE VENTILATION The following are excerpts from National Fuel Gas Code, ANSI Z223.1/NFPA 54, 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 6 through 8 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 10-11 kg per pa-sec-m2) or less with openings gasketed or sealed and b. weather stripping has been added on openable windows and 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 8. If your home does not meet all of the three criteria above, proceed to Determining Fresh-Air Flow For Heater Location, below. Confined and Unconfined Space The National Fuel Gas Code, ANSI Z223.1/NFPA 54 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. * 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 work sheet to determine if you have a confined or unconfined space. www.desatech.com 119426-01A AIR FOR COMBUSTION AND VENTILATION Continued Space: Includes the room in which you will install fireplace 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: Space size 20 ft. (length) x 16 ft. (width) x 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. Multiply the space volume by 20 to determine the maximum Btu/Hr the space can support. ___________ (volume of space) x 20 = (Maximum Btu/Hr the space can support) Example: 2560 cu. ft. (volume of space) x 20 = 51,200 (maximum Btu/Hr the space can support) 3. Add the Btu/Hr of all fuel burning appliances in the space. Vent-free fireplace ____________ 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. Example: 40,000 Btu/Hr Gas water heater ____________ 33,000 Btu/Hr Vent-free fireplace +_ __________ 73,000 Btu/Hr Total =_ __________ 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) 73,000 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. B. Vent room directly to the outdoors. See Ventilation Air From Outdoors, page 8. C. Install a lower Btu/Hr fireplace, 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. 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, ANSI Z223.1/NFPA 54 Section 5.3 or applicable local codes. VENTILATION AIR Ventilation Air From Inside Building 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 2). You can also remove door into adjoining room (see option 3, Figure 2). Follow the National Fuel Gas Code, ANSI Z223.1/NFPA 54, Section 5.3, Air for Combustion and Ventilation for required size of ventilation grills or ducts. 12" Ventilation Grills Into Adjoining Room, Option 1 Ventilation Grills Into Adjoining Room, Option 2 Or Remove Door into Adjoining Room, Option 3 12" Figure 2 - Ventilation Air from Inside Building 119426-01A www.desatech.com AIR FOR COMBUSTION AND VENTILATION Continued 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, ANSI Z223.1/NFPA 54, Section 5.3, 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 thermostatcontrolled power vent. Heated air entering the attic will activate the power vent. Outlet Air Ventilated Attic Outlet Air To Attic To Crawl Space Inlet Air Inlet Air Ventilated Crawl Space Figure 3 - Ventilation Air from Outdoors Installation NOTICE: This heater is intended for use as supplemental heat. Use this heater along with your primary heating system. Do not install this heater as your primary heat source. If you have a central heating system, you may run system’s circulating blower while using heater. This will help circulate the heat throughout the house. In the event of a power outage, you can use this heater as your primary heat source. WARNING: A qualified service person must install heater. Follow all local codes. NOTICE: State or local codes may only allow operation of this appliance in a vented configuration. Check your state or local codes. WARNING: Make sure the selector switch is in the OFF position before installing heater (Remote-Ready Models Only). WARNING: Before installing in a solid fuel burning fireplace, the chimney flue and firebox must be cleaned of soot, creosote, ashes and loose paint by a qualified chimney cleaner. Creosote will ignite if highly heated. A dirty chimney flue may create and distribute soot within the house. Inspect chimney and firebox flue for damage. If damaged, repair flue and firebox before operating heater. WARNING: Seal any fresh air vents or ash clean-out doors located on floor or wall of fireplace. If not, drafting may cause pilot outage or sooting. Use a heat-resistant sealant. Do not seal chimney flue damper. WARNING: Never install the heater • in a bedroom or bathroom unless installed as a vented appliance, see page 12 (Remote-Ready Models Only) • in a recreational vehicle • where curtains, furniture, clothing or other flammable objects are less than 42" from the front, top or sides of the heater • in high traffic areas • in windy or drafty areas www.desatech.com 119426-01A Installation Continued CAUTION: This heater creates warm air currents. These currents move heat to wall surfaces next to heater. Installing heater next to vinyl or cloth wall coverings or operating heater where impurities (such as, but not limited to, tobacco smoke, aromatic candles, cleaning fluids, oil or kerosene lamps, etc.) in the air exist, may discolor walls or cause odors. Important: Vent-free heaters add moisture to the air. Although this is beneficial, installing heater in rooms without enough ventilation air may cause mildew to form from too much moisture. See Air for Combustion and Ventilation, page 6. CHECK GAS TYPE Use the correct type of gas (natural or propane/LP). If your gas supply is not the correct gas type, do not install heater.

This heater requires an external regulator (not supplied). Install the external regulator between the heater and propane/LP supply. For propane/LP units, 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" 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 14. 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" diameter or greater to allow proper gas volume to heater. If pipe is too small, undue loss of volume will occur. Propane/LP Supply Tank WARNING: Never connect natural gas fireplace to private (non-utility) gas wells. This gas is commonly known as wellhead gas. Installation Items Needed Before installing heater, make sure you have the items listed below. • external regulator (supplied by installer) • piping (check local codes) • sealant (resistant to propane/LP gas) • equipment shutoff valve * • test gauge connection * • sediment trap • tee joint • pipe wrench • approved flexible gas line with gas connector (if allowed by local codes) (not provided) * A CSA design-certified equipment shutoff valve with 1/8" NPT tap is an acceptable alternative to test gauge connection. Purchase the optional CSA design-certified equipment shutoff valve from your dealer. See Accessories, page 42. 14 External Regulator Vent Pointing Down Figure 14 - External Regulator With Vent Pointing Down www.desatech.com 119426-01A Installation Continued Installation must include an 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 Figures 15 or 16, depending on your model). IMPORTANT: Install equipment shutoff valve in an accessible location. The equipment shutoff valve is for turning on or shutting off the gas to the appliance. Check your building codes for any special requirements for locating equipment shutoff valve to fireplaces. Apply pipe joint sealant lightly to male NPT threads. This will prevent excess sealant from going into pipe. Excess sealant in pipe could result in clogged heater valves. WARNING: Use pipe joint sealant that is resistant to liquid petroleum (LP) gas. We recommend that you install a sediment trap in supply line as shown in Figures 15 or 16, depending on your model. 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. CAUTION: Avoid damage to regulator. Hold gas regulator with wrench when connecting it to gas piping and/or fittings (Thermostatically-Controlled Models Only). CAUTION: Avoid damage to gas control. Hold gas control with wrench when connecting it to gas piping and/or fittings (Remote-Ready Models Only). 119426-01A Propane/LP From External Regulator (11" W.C.** to 14" W.C.

Yellow flame on rear burner is normal. NOTICE: Do not mistake orange flames with yellow tipping. Dirt or other fine particles are burned by heater, causing brief patches of orange flame. If front burner flame pattern is incorrect, as shown in Figure 39 • turn heater off (see To Turn Off Gas to Appliance, page 21 [Thermostat-Controlled Models] or page 23 [Remote-Ready Models]) • see Troubleshooting, page 28 Figure 38 - Correct Front Burner Flame Pattern Yellow Tipping At Top of Blue Flame Figure 39 - Incorrect Front Burner Flame Pattern 26 Cleaning and Maintenance WARNING: Turn off heater and let cool before cleaning. CAUTION: You must keep control areas, burners 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. WARNING: Failure to keep the primary air opening(s) of the burner(s) clean may result in sooting and property damage. 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 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 40, page 27). 3. Blow air through the ports/slots and holes in the burner. www.desatech.com 119426-01A Cleaning and Maintenance Continued 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 2" from where the pilot flame comes out of the pilot assembly (see Figure 41). 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. LOGS • If you remove logs for cleaning, refer to Installing Logs, page 18, to properly replace logs. • Replace log(s) if broken or chipped (dime-sized or larger). main burner Periodically inspect all burner flame holes with the heater running. All slotted burner flame holes should be open with yellow flame present. All round burner flame holes should be open with a small blue flame present. Some burner flame holes may become blocked by debris or rust, with no flame present. If so, turn off heater and let cool. Remove blockage, blocked burner flame holes will create soot.

Thermostat sensing bulb needs to be repositioned (Thermostat-Controlled Models Only) 1. Reposition thermostat sensing bulb (see Optional Positioning of Thermostat Sensing Bulb, page 32) 2. Move hand-held remote control unit farther away from the heater 119426-01A 2. Hand-held remote control is too close to heater (RemoteReady Models Only) www.desatech.com 31 Optional Positioning of Thermostat Sensing Bulb (Thermostat-Controlled Models Only) For Masonry and Factorybuilt Metal Fireplace If your log set cycles to pilot, but the room temperature drops to a lower than ideal comfort level before the log set comes back on, you may want to reposition the thermostat sensing bulb. The thermostat sensing bulb is located on the gas valve assembly. This location allows the thermostat to keep the room temperature at an ideal comfort level for most fireplace applications. For positioning the thermostat sensing bulb elsewhere, an adhesive-backed mounting clip is available (see Figure 42). Tools needed: 5/16" hex driver or socket 1. Locate the gas valve assembly and thermostat sensing bulb (see Figure 43). 2. With 5/16” hex driver or socket, loosen the thermostat screw. Carefully slide the thermostat sensing bulb out of the retaining clamp (see Figure 44). Note: Do not remove the screw. Make sure you tighten the screw after removing the thermostat sensing bulb. IMPORTANT: Do not force or bend the thermostat sensing bulb or capillary. 3. The thermostat sensing bulb may be located to the lower right front side of fireplace. Determine location of sensing bulb, but do not mount sensing bulb until step 4. If you have a masonry fireplace, see Figure 45 for location. If you have a factory-built metal fireplace, see Figure 46 for location. If your fireplace has glass doors, position sensing bulb directly behind door gap on right bottom side (see Figure 47).

The mounting clip must be a minimum of 3" from bottom of fireplace to prevent crimping of capillary. Once you have decided on a location, clean the area thoroughly. Remove the paper backing from the adhesive on back of mounting clip. Press the clip into the new location so that the thermostat sensing bulb will be positioned vertically with the capillary at the bottom (see Figure 48). Slide the thermostat sensing bulb into the clip. IMPORTANT: Do not crimp capillary.
