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 insulation 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 conduction through the total bottom
of appliance (see Figure 31).
