NEVER LEAVE THE HEATER UNATTENDED WHILE BURNING! NEVER LEAVE THE HEATER UNATTENDED WHILE BURNING! NEVER LEAVE THE HEATER UNATTENDED WHILE BURNING!
Caution: Do not try to adjust heating levels by using
the propane tank shut-off valve.
:
Warning
DO NOT OPERATE HEATER UNLESS CONTROL
KNOB IS LOCKED 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.
•
To shut off heater, shut off propane at supply tank,
allow heater to use-up propane in supply line until
heater shuts off, then slightly push down and turn
Control Knob clockwise to "OFF" position.
•
CAUTION: After turning heater off, wire guard will
remain hot. Allow to thoroughly cool before storing.
•
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 2. 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.
1 Allow heater to thoroughly cool before performing any
maintenance.
2 Remove disposable 1 lb. cylinder(s) from heater or turn
OFF gas supply at remote cylinder valve, and disconnect
hose from heater.
3 Remove wire guard from front of heater by gently
bending to remove from holes in front cover.
4 Remove (4) screws securing back cover to heater. Lift up
slightly to release (2) plastic hooks on top of back cover.
5 Remove back cover.
6 Remove (3) screws attaching lower baffle to expose
burner air openings.
7 Inspect interior of casing assembly for accumulation
of dust, lint or spider webs. If necessary, clean interior
of casing assembly with a vacuum cleaner or apply air
pressure. Do not damage any components within casing
assembly when you are cleaning.
8 Inspect and clean main burner orifice located at bottom
of burner venturi tube, by using a vacuum or apply air
pressure at orifice opening.
9 Inspect and clean pilot (mounted to bracket) by using a
vacuum or apply air pressure through the holes in the
pilot indicated by the arrows in Figure 2.
WARNING: Never use needles, wires, or similar
cylindrical objects to clean the pilot to avoid damaging
the calibrated ruby that controls the gas flow.
10 Apply air pressure into ceramic tile of burner(s) assembly
and the venturi tube (with [2] air openings) to remove
dust, lint or spider webs.
11 Reinstall lower baffle with (3) screws
12 Slide back cover over (2) plastic hooks on top of heater.
Make sure rear cover aligns with plastic side covers.
Install (4) screws to hold in place.
