PILOT ADJUSTMENT

Periodically check the pilot flames. Correct
flame pattern has three strong blue flames: 1
flowing around the thermopile and 1 around the
thermocouple, and 1 flowing across the rear of
the burner (it does not have to be touching the
burner).
Note: If you have an incorrect flame pat-
tern, contact your Regency
for further instructions.

Incorrect flame pattern will have small, probably
yellow flames, not coming into proper contact
with the rear of the burner or thermopile.

The aeration adjustment gears are located on
the right side of the burner box and can be ac-
cessed from the side or from the front when the
louvers are removed.
To adjust the aeration: use the allen key to turn
the turning gear which will adjust the air shutter.
Open the air shutter for a blue flame or close it
for a yellower flame.
Clockwise to open,
counter-clockwise to close.
Caution: Carbon will be produced if the air
shutter is closed too much.
Note: Any damage due to carboning result-
ing from improperly setting the aera-
tion controls is NOT covered under
warranty.
Note: Aeration Adjustment should only be
performed by an authorized Regency
Installer at the time of installation or
service.

NORMAL OPERATING
SOUNDS OF
GAS APPLIANCES
It is possible that you will hear some sounds from
your gas appliance. This is perfectly normal due to
the fact that there are various gauges and types
of steel used within your appliance. Listed below
are some examples. All are normal operating
sounds and should not be considered as defects
in your appliance.
Blower:
Regency gas appliances use high tech blowers
®
to push heated air farther into the room. It is not
unusual for the fan to make a "whirring" sound
when ON. This sound will increase or decrease
in volume depending on the speed setting of your
fan speed control.
Burner Tray:
The burner tray is positioned directly under the
burner tube(s) and logs and is made of a differ-
ent gauge material from the rest of the firebox
and body. Therefore, the varying thicknesses of
steel will expand and contract at slightly different
rates which can cause "ticking" and "cracking"
sounds. You should also be aware that as there
are temperature changes within the unit these
sounds will likely re-occur. Again, this is normal
for steel fireboxes.
Blower Thermodisc:
When this thermally activated switch turns ON
it will create a small "clicking" sound. This is the
switch contacts closing and is normal.
Pilot Flame:
While the pilot flame is on it can make a very slight
"whisper" sound.
Gas Control Valve:
As the gas control valve turns ON and OFF, a
dull clicking sound may be audible, this is normal
operation of a gas regulator or valve.
Unit Body/Firebox:
Different types and thicknesses of steel will expand
and contract at different rates resulting in some
"cracking" and "ticking" sounds will be heard
throughout the cycling process.
