CLEANING AND
MAINTENANCE

SERVICING
To assure safety, proper function and longevity
of the heater, regular maintenance is required.
The frequency of maintenance will depend on the
usage of the unit. Review the following concern-
ing the criteria for a properly functioning heater.
Failing to follow proper, regular maintenance will
void warranty.
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 burn-
ing 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: Do not use alternates. For this
heater, the regulator must be set as shown in Speci-
fications, page 2. If there is any uncertainty about
the regulator setting, have it checked.
