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:­The­heater­can­be­used­outdoors,­but­may­experence­
nuisance shutoffs due to certain wind conditions.
•­
When­the­heater­is­cold­or­at­room­temperature,­it­will­
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
qualified­service­technician.
•­
When­the­unit­is­lit,­there­should­be­about­a­quarter­
inch border around the tile that will not turn bright
orange. This is normal.
•­
When­operating­the­heater­for­the­first­time,­the­top­
area of the reflector may discolor. This is also normal
and is no reason for concern.
•­ The­protective­grill­on­the­front­of­this­heater­is­coated­
with­a­special­high-temperature­resistant­paint.­When­
the heater is used for the first time, the grill may give
off noticeable smoke or fumes. This is normal and will
not­occur­during­subsequent­uses.­The­fumes­are­not­
harmful.
•­
When­operating­the­heater­at­altitudes­over­7,000­FT.­
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(based­on­"HI"­and­"LO"­settings).
•­
When­moving­heater­when­lit­or­bumping­heater­setting­
it down, the tip over switch may shut off heater. If this
happens, re-light.
•
Due to natural operation of small tanks, condensation
may build up on tank and drip on surface under heater.
