Hearth Requirements

The Radiance Unvented heater must be installed on rigid flooring. If the appliance is installed on any com- bustible surface other than wood flooring, such as carpet or tile, a metal or wood panel must be installed to extend the full length and width of the unit. There are no other hearth or floor protection requirements.

WARNING

•Do not install this heater in a bathroom or bed- 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 with this heater.
