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. Do not use alternates. For this heater, the
regulator must be set to supply 11" water column (W.C.)
outlet pressure (.40 psig). 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. Contact the
factory for the service center closest to you, phone number
(909) 981-5343.

TECHNICAL INFORMATION
HOW MUCH HEAT DO I REQUIRE?
For economy, it is important to match input to that
required. But heat requirements often vary. For ex-
ample, it usually takes a lot more heat to get things warm
than it does to keep them that way. Likewise, outside air
temperature usually changes during the day so you may
need more heat at night than you do in the daytime. An
approximation of the heat required can be found by using
the chart below.
