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.

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
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.
