LOCATION AND SPECIAL PRECAUTIONS
The wall furnace should be located near the center of
the house for best heat distribution.
If the area where the appliance is to be installed contains
carpeting, tile or combustible materials, other than wood
flooring, the appliance shall be installed on a metal plate,
wood panel or other non-combustible materials. The use
of ceramic or quarry tile is acceptable and will provide a
surface that is easily cleaned. This material is to extend
the full width and depth of the appliance. If side or rear
warm air outlets are being installed, see figure 14 – 18,
See page 16 and 17.
