Product Features
The ceramic plaque heaters covered by this
service manual have many features that assure
customer satisfaction and comfort.
•
Infra-red Heat: The glowing ceramic burner
plaques give off infra-red radiant light which
travels through the air and heats nearby
objects.
•
Variable Heat Output: The non-thermostat
heaters can be adjusted to one of three
alternative heat settings to provide user
comfort. The thermostat heaters can be
adjusted to the desired heat setting to per-
mit economical use. In the event of a power
outage, the heater can be operated manu-
ally on high or low.
•
Piezo Electric Ignition: The heater can be
started and operated without matches or
other external means. The pilot is ignited by
a spark created from the piezo ignitor when
the control knob is depressed and turned to
the “PILOT” position.
•
Oxygen Depletion System: The heater is
designed to shut off if the oxygen level in
the room falls to an unacceptable level.
