IN A POSITION MARKED "HI", "MD", "LO"or "PILOT". NEVER
SET CONTROL KNOB BETWEEN LOCKED POSITIONS. POOR
COMBUSTION AND HIGHER LEVELS OF CARBON MONOXIDE
MAY RESULT.
•
Installation of 4 D-cell batteries is required for fan
operation. Battery box is located on lower back panel of
heater. Follow instructions on battery cover for correct
battery installation. See figure 2.
•
Heater can also be powered by electrical adapter,
F276127. Required adapter to be 6 volt DC up to 800 mil-
liamp current with positive tip polarity. See figure 2.

•
When not in use, the gas must be turned off at the
LP-gas supply cylinder. As stated before allow heater
to use up propane in supply line until heater shuts off.
When the LP-gas supply cylinder is not disconnected
from the heater, the heater and the cylinder must be
stored outdoors, in a well ventilated space, out of reach
of children, and must not be stored in a building, garage
or any other enclosed area.
•
Indoor storage of the heater is permissible only if the
cylinder is disconnected and removed from the heater.
Cylinders must be stored outdoors out of the reach of
children and must not be stored in a building, garage or
any other enclosed area.
MaInTenanCe:
Always keep the heater area clear and free from combustible
materials, gasoline and other flammable vapors and liquids.
Keep the vent areas (slots in the bottom and the top at the front
of heater) clear at all times.
Visually inspect the pilot flame and burner periodically during
use. The pilot flame should be blue in color (not yellow) and will
extend beyond the thermocouple. The flame will surround the
thermocouple just below the tip, see Figure 3. A slight yellow
flame may occur where the pilot flame and main burner flame
meet. The burner(s) should be bright orange (with a slight blue
color around the border, a red-orange haze that is visible on the
ceramic tile is acceptable) and without a noticeable flame.
A blue flame that rolls out at the top of the ceramic tile indicates
an accumulation of dust, lint or spider webs inside the casing
assembly and main burner assembly. If the pilot is yellow or the
burner has a noticeable flame, cleaning may be required. Use
the following procedure to inspect the casing assembly and main
burner assembly.
It is necessary to periodically check the burner(s) orifice and
burner venturi tube to make sure they are clear of insects/nests or
spider webs that may accumulate over time. A clogged tube can
lead to a fire.
