NOTICE:
Risk of appliance freezing!
▶ In areas where outside temperature is routinely below 32°F
(0 °C) and the heater is to be installed on the inside of an
exterior wall, a minimum 2" air gap or rigid insulation
between the heater back and the wall is recommended.
If wall is sheathed with plaster or drywall, it is recommended
that two support boards, either 1"x 4" or 1/2" (minimum)
plywood first be attached across a pair of studs, see fig. 27,
page 36.
▶ Secure the wall mounting bracket provided with the heater
to a wall surface. The heater must be kept level on the wall
surface, see fig. 28, page 36.
