Cautions; All Systems Working Together; Troubleshooting - Desa PG15EA Service Manual

CAUTIONS

1. Before servicing, disconnect the heater from
the electrical power source by removing the
electrical plug from the wall receptacle.
Note: When certain tests require electrical power
to be applied, connect electrical power only for
the time necessary to complete the test.
2. Do not bypass safety devices except when
instructed to do so during troubleshooting
procedures.
3. If replacement parts are necessary, do not
substitute with non-factory parts (use only
factory authorized replacement parts).
4. Make sure all electrical connections are secure
and correct prior to connecting heater to a
grounded electrical power source.
ALL SYSTEMS WORKING
TOGETHER
There are three basic systems within the heater, the
heating system, air system and safety system.
A tubular heating element (A) warms the sur-
rounding air.
A fan (B) on one end of a motor (C) draws air into
the product. This air is directed over the heating
element to create warm heated air out.
An over temperature switch (D) shuts the heater off
in the abnormal event a motor were to fail.
A tip over switch (E) shuts the heater off in the
event the product is tipped over.
