GENERAL INFORMATION:
This heater is safe for indoor use in small recre-
ational 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 in commercial
enclosures, having means for providing combustion air
and ventilation, such as construction trailers or tempo-
rary 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 prop-
erly. 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 operating the heater at altitudes over 7,000
FT. above sea level, the unit may not burn as bright
as in lower altitudes. This is normal. At higher
altitudes, the heater may shut-off. If this happens,
provide fresh air, wait 5 minutes and re-light. Due to
local atmospheric conditions heater may not re-light.
Operating time will vary depending on the heater
setting and the supply cylinder size. 3 to 6 hours on
a 1 lb. cylinder. 48 to 110 hours on a 20 lb. cylinder
(based on “HI” and “LO” settings).
When moving heater when lit or bumping heater
setting it down, tip over switch may shut off heater. If
this happens, re-light.
Due to natural operation of small tanks, condensa-
tion may build up on tank and drip on surface under
