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 hangtag 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.
