SERVICING

A hazardous condition may result if a heater is used that has
been modified or is not functioning properly. When the heater is
working properly:
• The flame is contained within the heater.
• The flame is essentially blue with perhaps some yellow
tipping.
• There is no strong disagreeable odor, eye burning or other
physical discomfort.
• There is no smoke or soot internal or external to the heater.
• There are no unplanned or unexplained shut downs of the
heater.
The parts lists and wiring diagram show the heater as it was
constructed. Do not use a heater which is different from that
shown. In this regard, use only the hose, regulator and cylinder
connection fitting (called a POL fitting) supplied with the heater.
IMPORTANT: Match the color stripe on the hang tag attached
to the hose assembly with the color on the label located near the
propane inlet fitting on the heater. Do not use alternates. For this
heater, the regulator must be set as shown in "specifications".
If there is any uncertainty about the regulator setting, have it
checked.
A heater which is not working right must be repaired, but only by
a trained, experienced service person.
In-warranty products will be repaired with no charge for either
parts or labor. Please include a brief statement indicating date,
place of purchase, the nature of the problem and proof of
purchase.
Out of warranty products will be repaired with a charge for parts
and labor.
HEATER ELEVATION ADJUSTMENT

located at the exhaust end of the control box.

heater is running or hot. Adjustments to elevation should
only be made after the heater has cooled to touch.

the adjustment screw knob counterclockwise and lift the
