16 Regency U38 ULTIMATE Freestanding Gas Stove
NORMAL OPERATING
SOUNDS OF
GAS APPLIANCES
It is possible that you will hear some sounds
from your gas appliance. This is perfectly nor-
mal due to the fact that there are various gauges
and types of steel used within your appliance.
Listed below are some examples. All are nor-
mal 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
different gauge material from the rest of the
firebox and body. Therefore, the varying thick-
nesses of steel will expand and contract at
slightly different rates which can cause "tick-
ing" 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.
AERATION
ADJUSTMENT
The burner aeration is factory set but may need
adjusting due to either the local gas supply or
altitude.
U38 with 40,000 Btu/h
U38-NG Natural Gas: 1/4" open
U38-LP Propane: 1/2" open
U38 with 30,000 Btu/h
U38-NG Natural Gas 3/16" open
U38-LP Propane 3/8" open
The aeration adjustment gears are located on
the right side of the burner box and can be
accessed 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.

OPERATING INSTRUCTIONS
PILOT ADJUSTMENT
Periodically check the pilot flames. Correct flame
pattern has three strong blue flames: 1 flowing
around the thermopile and 1 around the thermo-
couple, 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
pattern, contact your Regency
dealer for further instructions.
Incorrect flame pattern will have small, proba-
bly yellow flames, not coming into proper con-
tact with the rear of the burner or thermopile.
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 re-
sulting from improperly setting the
aeration 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.
