Inspecting Burners - Procom PFS PCS100T Owner's Operation And Installation Manual

The thermostatic control used on this model
differs from standard thermostats. Standard
thermostats simply turn the burner on and off.
The thermostat used on this heater senses the
room temperature. At times the room may ex-
ceed the set temperature. If so, the burner will
shut off. The burner will cycle back on when
Shutting Off Heater
Turn control knob clockwise
OFF position.
1. Remove screen by lifting and pulling
forward.
2. Follow steps 1 through 5 under Lighting
Instructions, page 18.
3. With control knob in PILOT position, strike
match, and hold near pilot. Press in control
knob; pilot should light.
IMPORTANT: Owner's should check pilot flame pattern and burner flame pattern often.
Incorrect flame patterns indicate the need for cleaning (see Care and Maintenance,
page 21) or service.
WARNING: Only a qualified service person should service and
repair heater. This includes maintenance requiring replacement or
alteration of components.
Figure 24, page 21, shows a correct pilot
flame pattern. Figure 25, page 21, 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, as shown in
Figure 25, page 21,
• turn heater off (see To Turn Off Gas to Ap-
pliance, page 19)
• see Troubleshooting pages 23 through 26.
