room.
• Installation of this heater must conform with local

codes or, in the absence of local codes, with the

National Fuel Gas Code, ANSI Z223.1/NFPA 54.
• This heater creates warm air currents. These

currents move heat to wall surfaces next to the

heater. Installing the heater next to vinyl or cloth

wall coverings or operating the heater where im-

purities in the air such as tobacco smoke exist,

may discolor walls.
• Do not use a blower insert, heat exchanger

insert or other accessory not approved for use
