Louisville Tin and Stove BFT201 - Manual (Page 4)

7) Installation and repair should be done by a qualified technician. The heater should be inspected before use and
at least annually by a professional service technician. More frequent cleaning may be required due to excessive
lint from carpeting, bedding, material, etc. It is imperative that control compartments, burners, and circulating air
passageways of the heater be kept clean.
8) “WARNING: Any modifications to this heater or its controls can be dangerous”.
9) Do not use this heater if any part has been under water. Immediately call a qualified service technician to inspect
the heater and to replace any part of the control system and any gas control which has been under water.
10) Due to high surface temperatures, keep children, clothing, and furniture away.
11) Do not install this heater in a recreational vehicle.
12) Never use a match, candle, flame or other source of ignition to check for gas leaks. Use only soapy water or
liquid detergent.
13) Before cleaning or servicing, turn off the gas and allow heater to cool.
14) Do not put objects around the heater that will obstruct the flow of combustion and ventilation air.
15) When installing the heater allow adequate accessibility clearances for servicing and proper operation.
16) Keep appliance area clear and free from combustible materials, gasoline and other flammable vapors and liquids.
17) Do not install in a residential or commercial garage.
18) WARNING: Do not use a blower or other accessory not approved for use with this heater.
19) WARNING: Failure to keep the primary air opening(s) of the burner(s) clean may result in sooting and property
damage.
20) This appliance is intended for supplemental heating.

FRESH AIR FOR COMBUSTION, VENTILATION AND HEAT DISTRIBUTION
With todays energy efficient homes, it is possible to make your home so air tight that it can result in stale air, dry rot, mold
development and host of other related problems. Gas burning appliances need fresh air for combustion as well as for
good distribution of heated air throughout the home. The following guide provides good general rules for classifying and
properly ventilating most homes.
“This heater shall not be installed in a confined or unusually tight construction unless provisions are provided for
adequate combustion and ventilation air.”
“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/NFPA 54, the International Fuel Gas Code, or
applicable local codes.”
“WARNING: If the area in which the heater may be operated does not meet the required volume for indoor combustion
air, combustion and ventilation air shall be provided by one of the methods described in the National Fuel Gas Code,
ANSI Z223.1/NFPA 54, the International Fuel Gas Code, or applicable local codes.”
“A confined space is a space whose volume is less than 50 ft³ per 1000 Btu/hr (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 ft³
per 1000 Btu/hr (4.8 m³ per kw) of the aggregate input rating of all appliances installed in that space. Rooms communi-
cating directly with the space in which the appliances are installed, through openings not furnished with doors, are
considered a part of the unconfined space.”
Use the following example to determine if the heater is being installed in a confined or unconfined space.
STEP 1. First find the cubic feet of area to be heated length x width x height. NOTE: Include any adjoining rooms that
cannot be separated by closing a door or that have a air exchange grille that cannot be closed between rooms.
EXAMPLE: Area size 25 ft. x 15 ft. x 7-1/2 ft. = 2,812.5 cubic feet.
STEP 2. Divide area cubic feet by 50. EXAMPLE: 2,812.5 ÷ 50 = 56.25. Multiply this number by 1,000 for total Btu input
room can support. E XAMPLE: 56.25 x 1,000 = 56,250 Btu.
STEP 3. List all gas burning appliances in this area and total the combined Btu input. EXAMPLE:
Cozy vent free heater…………………….. 20,000 Btu
Gas water heater………………………….. 58,000 Btu
Gas range (all burners & oven on)……….. 28,000 Btu
106,000 Btu
