OPERATION
THERMOSTATIC CONTROL OPERATION (SELECT MODELS)
The control knob can be set to any comfort level between
"HIGH" (5) and "LOW"(1) (See Fig. 25).The thermostat used on
this heater senses the room temperature. At times the room may
exceed the set temperature. When this begins to happen, the
burner will begin to modulate the BtuH down until the unit meets
the desired heat setting and shuts off. When the room
temperature drops below the desired heat setting, the burner will
cycle back on. The unit may start at a lower BtuH rate if the room
is still warm.
MANUAL CONTROL OPERATION
Manual valves remain burning at the desired setting until
manually turned to OFF "
INSPECTING BURNERS
Check pilot flame pattern daily when in use and at least yearly by a qualified service agency.
PILOT FLAME PATTERN
Fig. 26 shows a correct pilot flame pattern. Fig. 27 shows an incorrect pilot flame pattern. The
incorrect pilot flame is not touching the thermocouple. This will cause the thermocouple to cool,
which shuts the heater off. If pilot flame pattern is incorrect:
• turn heater off (see "To Turn Off Gas to Appliance" on page 19)
• see Troubleshooting pages 23 through 26.
