Air for combustion is drawn in through the frontof the unit, therefore, the front of the unit must
be kept clear of any obstructions.

GAS PIPE
PRESSURE TESTING
The appliance must be isolated from the gas
supply piping system by closing its individual
manual shut-off valve during any pressure
testing of the gas supply piping system at test
pressures equal to or less than 1/2 psig. (3.45
kPa). Disconnect piping from valve at pressuresover 1/2 psig.
The manifold pressure is controlled by a regulator
built into the gas control, and should be checkedat the pressure test point.
Note: To properly check gas pressure, both
inlet and manifold pressures should
be checked using the valve pressure
ports on the valve.
1) Make sure the valve is in the "OFF"position.
2) Loosen the "IN" and/or "OUT" pressuretap(s), turning counterclockwise with a 1/8"
wide flat screwdriver.
3) Attach manometer to "IN" and/or "OUT"
pressure tap(s) using a 5/16" ID hose.
4) Light the pilot and turn the valve to "ON"position. Read manometer.
5) The pressure check should be carried out
with the unit burning and the setting should
be within the limits specified on the safety
label.
6) When finished reading manometer, turnoff the gas valve, disconnect the hose andtighten the screw (clockwise) with a 1/8"
flat screwdriver. Note: Screw should besnug, but do not over tighten

FIRST FIRE
The first fire in your stove is part of the paintcuring process. To ensure that the paint isproperly cured, it is recommended that you
burn your fireplace for at least four (4) hours thefirst time you use it with the fan on. When first
operated, the unit will release an odour causedby the curing of the paint, the burning off of
any oils remaining from manufacturing. Smoke
detectors in the house may go off at this time.
Open a few windows to ventilate the room fora couple of hours.
The glass panel may require cleaning after theunit has cooled down.

DO NOT ATTEMPT TO CLEAN THE
GLASS WHILE IT IS HOT.
Do not use abrasive cleaners on
the glass.
Note: When the glass is cold and theappliance is lit, it may cause
condensation and fog the glass.
This condensation is normal and will
disappear in a few minutes as theglass heats up.

NORMAL OPERATINGSOUNDS OF GASAPPLIANCES
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" soundwhen ON. This sound will increase or decreasein volume depending on the speed setting ofyour fan speed control.
Burner Tray:
The burner tray is positioned directly under theburner tube(s) and logs and is made of a different
gauge material from the rest of the firebox andbody. 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 thesesounds 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 theswitch contacts closing and is normal.
Pilot Flame:
While the pilot flame is on it can make a veryslight "whisper" sound.
Gas Control Valve:
As the gas control valve turns ON and OFF, adull 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 beheard throughout the cycling process.

MAINTENANCE
INSTRUCTIONS
1) Always turn the gas valve to off before
cleaning. For relighting, refer to lighting
instructions. Keep the burner and control
compartment clean by brushing andvacuuming at least once a year.
When cleaning the logs, use a clean soft
paint brush as the logs are fragile and easily
damaged.
2) Clean (never when unit is hot) appliance,
door and louvers with a damp cloth. Neveruse an abrasive cleaner. The gold louvers(and optional gold door) may be scratched
if abrasives are used to clean them.
The heater is finished in a heat resistantpaint and should only be refinished withheat resistant paint (not with wall paint).
Regency® uses StoveBrite Paint - Metallic
Black #6309.
3) Make a periodic check of burner for proper
position and condition. Visually check theflame of the burner periodically, making surethe flames are steady; not lifting or floating.
If there is a problem, call a qualified service
person.
4) The appliance and venting system must be
inspected before use, and at least annually,
by a qualified field service person, to ensurethat the flow of combustion and ventilation
air is not obstructed.
During the annual service call, the burners
should be removed from the burner tray
and cleaned. Replace the embers but do
not block the pilot.
5) Keep the area near the appliance clear andfree from combustible materials, gasoline
and other flammable vapours and liquids.
6) Each time the appliance is lit, it may cause
condensation and fog the glass. Thiscondensation and fog is normal and will
disappear in a few minutes as the glass
heats up.

Never operate the appliance without
the glass properly secured in placeor with the door open.
7) Verify proper operation after servicing.
8) Periodically check the pilot flames, see thediagrams in the "Valve Description" section.
If you have an incorrect flame pattern,
contact your Regency® dealer for further
instructions.
