It is best to provide outside clean air to heater inlet and adequate ventilation to heated areas. The
hose assembly shall be protected from traffic, damage, building materials and contact with hot sur-
faces.
Check all connections for leaks.
Turn off fuel supply and burn out leftover fuel in hose when heater is not in use.
Heater can be ducted up to 200 ft of
straight
27” duct. For every 90˚ bend cut the total length in
half.
If the heater is ducted it may be necessary to adjust the air flow switch (located inside control box)
by turning adjusting screw CCW until the light on the control box turns on.
If the heater is equipped with a Hi/Lo Fire Thermostat, place the thermostat inside the area to be
heated, then set desired temperature. Heater will cycle from high to low fire.
