INSTALLATION
For minimum and maximum supply pressure 
see the Specifi cations table.
1. If the appliance is to be installed into an
existing chimney system, thoroughly clean 
the masonry fi replace that has been chosen 
for the Regency
®
Gas Fireplace.
2. The appliance is provided with an opening
on the left hand side of the control 
compartment for the gas line.
Note: During any pressure testing of the 
gas supply piping system that exceeds test 
pressures of 1/2 psig, this appliance and its 
individual shut-off valve must be disconnected 
from the piping system. If test pressures equal 
to or less than 1/2 psig are used then this 
appliance must be isolated from the piping 
system by closing its individual manual shut-off 
valve during the testing.
CAUTION: If the glass is removed for 
servicing, it must be replaced prior to 
operating the appliance. The glass must be 
fi xed in the closed position when operating.
GAS CONNECTION
Only persons licensed to work with gas piping 
may make the necessary gas connections to 
this appliance. 
The gas connection is a 1/2" NPT accessible on 
the left side of the unit. The gas line connection 
may be made of rigid pipe, copper pipe or an 
approved fl ex connector. (If you are using rigid 
pipe, ensure that the valve can be removed 
for servicing.) Since some municipalities have 
additional local codes it is always best to consult 
with your local authorities and the CAN/CGA 
B149 installation code.
For USA installations follow local codes and/
or the current National Fuel Gas Code, ANSI 
Z223.1.
When using copper or fl ex connectors use only 
approved fi ttings. Always provide a union so that 
gas lines can be easily disconnected for burner 
or fan servicing. Flare nuts for copper lines and 
fl ex connectors are usually considered to meet 
this requirement.
Important: Always check for gas leaks 
with a soap and water solution or gas 
leak detector. Do not use open fl ame 
for leak testing.
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 pressures 
over 1/2 psig.
The manifold pressure is controlled by a 
regulator built into the gas control, and should 
be checked at 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" pressure
tap(s), turning counterclockwise with a 1/8" 
wide fl at 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 specifi ed on the safety 
label.
6. When fi nished reading manometer, turn
off the gas valve, disconnect the hose and 
tighten the screw (clockwise) with a 1/8" 
fl at screwdriver. Note: Screw should be 
snug, but do not over tighten.
