• A periodic sniff test around the heater or at the heater’s
joints; i.e. hose, connections, etc., is a good safety
practice under any conditions. If you smell even a small
amount of gas, CONTACT YOUR FUEL GAS SUPPLIER
IMMEDIATELY. DO NOT WAIT!
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 when
connected to a disposable 1-lb. propane cylinder and
for indoor use 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 experi-
ence 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 or-
ange. 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.
• The protective grill on the front of this heater is coated
with a special high-temperature resistant paint. When
the heater is used for the first time, the grill may give
off noticeable smoke or fumes. This is normal and will
not occur during subsequent uses. The fumes are not
harmful.
• 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 set-
ting and the supply cylinder size. Up to 3 to 6 hours
on a 1 lb. cylinder. Up to 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 hap-
pens, re-light.
•
Due to natural operation of small tanks, condensation
may build up on tank and drip on surface under heater.
