SAFETY INFORMATION
Continued
8. This heater needs fresh, outside air ventilation
to run properly. This heater has an Oxygen
Depletion Sensing (ODS) safety shutoff sys-
tem. The ODS shuts down the heater if not
enough fresh air is available. You must provide
a minimum 10 square inches (6.5 square cm)
of ventilation air for adequate combustion.
9. If heater shuts off, do not relight until you
provide fresh, outside air. If heater keeps
shutting off, have it serviced.
10. Keep all air openings in front and bottom of
heater clear and free of debris. This will insure
enough air for proper combustion.
11. Do not use heater if any part has been under
water. Immediately call a qualified service
technician to inspect the room heater and to
replace any part of the control system and any
gas control which has been under water.
12. When heater is placed on the ground, make sure
the ground is level and keep any objects at least
24" (60 cm) from the front of the heater. This
heater is equipped with a tip over switch that
will shut the heater off if the heater tips over.
However, do not leave heater unattended or
where children may cause the heater to tip over.
Never operate the heater while sleeping!
13. Gas pressure at heater is regulated and fixed
at 11" W.C. When using a remote hose con-
nection do not regulate or reduce propane tank
supply pressure to heater!
14. Regulator in heater must always be in place
during operation.
15. Turn off and let cool before servicing. Only
a qualified service person should service and
repair heater.
16. Turn off propane/LP supply when not in
use.
17. Check heater for damage before each use. Do
not use a damaged heater.
18. Do not alter heater. Keep heater in its original
state.
19. Do not use heater if altered.
20. Before using the heater provide adequate
ventilation. An area of 10 square inches (6.5
square cm) of opening of a window or roof
vent is needed for adequate combustion and
ventilation air.

21. This heater is safe for indoor use in small
recreational enclosures, having means for pro-
viding 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/LP
cylinder and for indoor use in commercial
enclosures, having means for providing com-
bustion air and ventilation, such as construction
trailers or temporary work enclosures.
22. When the heater is cold or at room tempera-
ture, 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.
23. When the unit is lit, there should be about a
quarter inch border around the tile that will
not turn bright orange. This is normal.
24. 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.
25. When operating the heater at altitudes over
7,000 feet (2,100 m) 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 relight heater.
26. Operating time will vary depending on the
heater setting and the supply cylinder size.
3 to 6 hours on a 1 lb. (0.45 kg) cylinder. 48
to 110 hours on a 20 lb. (9 kg) cylinder (based
on HI and LO settings).
27. Moving heater when lit or bumping heater
while setting it down may cause tip over
switch to shut off heater. If this happens relight
heater.
Install and use heater with care. Follow all lo-
cal codes. In the absence of local codes, use the
latest edition of National Fuel Gas Code, ANSI
Z223.1/NFPA 54*.
