OUTDOOR INSTALLATION (Outdoor Shelter Installation in Canada, see page 15)

For outdoor installation with an exhaust grill, the heater must be placed in a suitable area on a level, noncombustible surface. Do not install the heater under an overhang with clearances less than 3 feet from the top of the heater. The area under an overhang must be open on three sides.

IMPORTANT!

In an outdoor installation it is important to ensure water is diverted from overhanging eves with a proper gutter/drainage system. The heater must be set on a level foundation for proper drainage.

Under certain conditions, “heavy rains or unusually high winds”, it may be necessary to install an outdoors vent. In this situation, use Outdoor Vent Kit, P/N 460424, (see below).

This unit shall not be operated outdoors at temperatures below -20oF.
