Inspecting Burners - Procom PCSD25T Owner's Operation And Installation Manual

The Thermo Feature on the transmitter op-
erates the appliance whenever the ROOM
TEMPERATURE varies a certain number of
degrees from the SET TEMPERATURE.
This variation is called the "swing" or tem-
perature differential. The normal operating
cycle of an appliance may be 4 times per
hour depending on how well the room or
home is insulated from the cold or drafts.
The factory setting for the "swing number" is
2. This represents a temperature variation of
+/-2°F (1°C) between SET temperature and
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 24 or service.
WARNING: Only a qualified service person should service and
repair heater. This includes maintenance requiring replacement or
alteration of components.
Figure 26 shows a correct pilot flame pattern.
Figure 27 shows an incorrect pilot flame pat-
tern. The incorrect pilot flame is not touching
the thermocouple. This will cause the ther-
mocouple to cool, which shuts the heater off.
If pilot flame pattern is incorrect, as shown
in Figure 27
• turn heater off (see To Turn Off Gas to Ap-
pliance, page 19 or 20)
• see Troubleshooting pages 26 through 28.
WARNING: If yellow tipping
occurs, your heater could pro-
duce increased levels of carbon
monoxide. If the burner flame
pattern shows yellow tipping,
follow instructions at bottom of
this page.

ROOM temperature, which determines when
the fireplace will be activated. The transmitter
has ON and OFF manual functions that are
activated by pressing either button on the
face of the transmitter. When a button on the
transmitter is pressed the word ON or OF will
appear on the LCD screen to show while the
signal is being sent. Upon initial use, there
may be a delay of three seconds before the
remote receiver will respond to the transmitter.
This is part of the system's design.
Notice: Do not mistake orange flames with
yellow tipping. Dirt or other fine particles enter
the heater and burn causing brief patches of
orange flame.
