heater is installed outside. See Fig. 1.
FIG. 1
3. This heater may be installed either indoors or
outdoors. For indoor installations, the heater must
be vented to outside. See Figs. 2 & 3 on page 7 for
chimney set-up and installation.
4. The heater may be ducted. Use only 20 ft. flexible
duct, Part #24220, and duct adapter, Part #24221.
Both parts are optional accessories. Do not use any
other length of duct, field fabricated ducts, or
adapters, stove pipes, etc. Locate the duct under
suitable wind barrier materials for jobsite
requirements.

of any combustible vegetation and other combustible
materials when the heater is used.
11. Eventually, like all electrical/mechanical devices, the
thermostat can fail. Thermostat failure may result in
an underheating condition. The thermostat should be
tested to make sure it turns the heater on and off
within a temperature differential of ±3°F.
12. Take time to understand how to operate and maintain
the heater by using this Owner’s Manual. Make sure
you know how to shut off the power supply to the
