APPLIANCE ENCLOSURE
Before finishing enclosure around appliance,
inspect all joints around outer surround. Any
gaps between nailing flanges and framing
should be sealed with noncombustible insula-
tion or caulking.
If appliance is mounted on a raised platform,
it must be a continuous surface and not
on blocks without a solid surface. This will
prevent the entry of cold air by means of con-
duction through the total bottom of appliance
(see Figure 34).
