MAINTENANCE
GENERAL VENT
MAINTENANCE
Conduct an inspection of the venting system semi-
annually. Recommended areas to inspect as follows:
1) Check the Venting System for corrosion in areas
that are exposed to the elements. These will
appear as rust spots or streaks, and in extreme
cases, holes. These components should be
replaced immediately.
2) Remove the Termination Cap, and shine a
fl ashlight down the Vent. Remove any bird nests,
or other foreign material.
3) Check for evidences of excessive condensation,
such as water droplets forming in the inner
liner, and subsequently dripping out the joints,
Continuous condensation can cause corrosion
of caps, pipe, and fi ttings. It may be caused
by having excessive lateral runs, too many
elbows, and exterior portions of the system
being exposed to cold weather.
4) Inspect joints, to verify that no pipe sections or
fi ttings have been disturbed, and consequently
loosened. Also check mechanical supports such
as Wall Straps, or plumbers' tape for rigidity.
LOG REPLACEMENT
The unit should never be used with broken logs. Turn
off the gas valve and allow the unit to cool before
opening door to carefully remove the logs. The pilot
light generates enough heat to burn someone. If for
any reason a log should need replacement, you
must use the proper replacement log. The position
of these logs must be as shown in the diagram
under Log Installation.
NOTE: Improper positioning of logs may create
carbon build-up and will alter the unit’s performance
which is not covered under warranty.
GLASS GASKET
If the glass gasket requires replacement use glass
gasket for the Flush Front (Part # 936-112).
PILOT ADJUSTMENT
Periodically check the pilot fl ames. Correct
fl ame pattern has three strong blue fl ames: 1
fl owing around the thermopile, 1 around the
thermocouple and 1 fl owing across the burner
(it does not have to be touching the burner).
Note: If you have an incorrect fl ame pattern,
contact your Regency ® dealer for further
instructions.
Incorrect fl ame pattern will have small, probably
yellow fl ames, not coming into proper contact
with the rear burner or fl ame sensor.
