GENERAL INFORMATION:
• This heater is safe for indoor use in small recreational
enclosures, having means for providing combustion
air and ventilation, such as enclosed porches, cabins,
fishing huts, trailers, tent trailers, tents, truck caps and
vans. It may be used for emergency indoor heating and
in commercial enclosures, having means for providing
combustion air and ventilation, such as construction
trailers or temporary work enclosures.
Note: The heater can be used outdoors, but may
experience nuisance shutoffs due to certain wind
conditions.
• When the heater is cold or at room temperature, it
will take a few minutes for the burner tile to turn
bright orange. This is normal and the heater is working
properly. If burner tile is visibly flaming, turn heater off
and call a qualified service technician.
• When the unit is lit, there should be about a quarter
inch (1/4”) border around the tile that will not turn
bright orange. This is normal.
• When operating the heater for the first time, the top
area of the reflector may discolor. This is also normal
and is no reason for concern.

• When moving heater when lit or bumping heater setting
it down, tip over switch may shut off heater. If this
happens, re-light.
