SAFETY INFORMATION Continued 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.
SAFETY INFORMATION Continued 6. Do not add extra logs or ornaments such as pine cones, vermiculite, or rock wool. Using these added items can cause sooting. Do not add lava rock around base. Rock and debris could fall into the control area of fireplace. 7. To prevent the creation of soot, follow the instructions in Cleaning and Maintenance, page 21. 8. Before using furniture polish, wax, carpet cleaner, or similar products, turn heater off.
Local Codes Safety Device Continued State of Massachusetts: The installation must be made by a licensed plumber or gas fitter in the Commonwealth of Massachusetts. Sellers of unvented propane or natural gas-fired supplemental room heaters shall provide to each purchaser a copy of 527 CMR 30 upon sale of the unit. Vent-free gas products are prohibited for bedroom and bathroom installation in the Commonwealth of Massachusetts.
AIR FOR COMBUSTION AND VENTILATION Continued 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.
AIR FOR COMBUSTION AND VENTILATION Continued Example: 40,000 Gas water heater _______________ Btu/Hr 33,000 Vent-free fireplace +______________ Btu/Hr 73,000 Total =______________ Btu/Hr 4. Compare the maximum Btu/Hr the space can support with the actual amount of Btu/Hr used.
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 fireplace. Follow all local codes.
Installation Trim Hanging Screws Continued Rail Hood Hanging Notches on Trim Screw Figure 5 - Installing Hood Assembling and attaching OPTIONAL perimeter trim (Included with Mantel Accessory) IMPORTANT: If you are recessing the firebox in a wall, do not attach trim at this time. See Built-In Fireplace Installation, page 11. Note: The instructions below show assembling and attaching trim to fireplace. 1. Remove packaging from three pieces of trim. 2.
Installation Continued Conventional Fireplace Installation Conventional installation of this fireplace involves installing fireplace along with the corner, face, or cabinet mantel with hearth base accessories against a wall in your home. Follow the instructions in this section to install the fireplace in this manner. 1. Assemble cabinet mantel, hearth base, and trim accessories. Assembly instructions are included with each accessory. 2.
5. Carefully insert fireplace into rough opening. 6. Attach flexible gas line to gas supply. See Connecting Fireplace to Gas Supply, page 14. 7. Attach fireplace to wall studs using nails or wood screws through holes in nailing flange (see Figure 15). 8. Check all gas connections for leaks. See Checking Gas Connections, page 15. 9. Plug electrical cord into electrical outlet installed in step 2. 10. Install trim after final finishing and/or painting of wall (see Figure 7, page 9).
Installation Installing Gas Piping to Fireplace Location Continued Mantel Clearances for Built-In Installation If placing mantel above built-in fireplace, you must meet minimum clearance between mantel shelf and top of fireplace opening. Notice: If your installation does not meet the minimum clearances shown, you must do one of the following: • raise the mantel to an acceptable height • remove the mantel NOTICE: Surface temperatures of adjacent walls and mantels become hot during operation.
Installation Continued 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 17. Pointing the vent down protects it from freezing rain or sleet. CAUTION: Use only new, black iron or steel pipe.
Installation Continued CONNECTING Fireplace to Gas Supply Installation Items Needed • 5/16" hex socket wrench or nut-driver • Phillips screwdriver • sealant (resistant to propane/LP gas, not provided) 1. Remove fireplace screen. Remove two screws that hold fireplace screen in place for shipping. These screws are located near top of screen. Discard screws. Lift fireplace screen up and pull out to remove. 2. Remove screws that attach log base assembly to fireplace (see Figure 19).
Installation Open Continued CAUTION: Make sure external regulator has been installed between propane/LP supply and fireplace. See guidelines under Connecting Fireplace to Gas Supply, page 14.
