Installation manual
UltraGlow G36D Zero Clearance Direct Vent Gas Fireplace 23
INSTALLATION
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.
HIGH ELEVATION
This unit is approved in Canada for altitude 0 
to 4500 ft. (CAN1 2.17-M91) with the orifi ce 
supplied.
GAS LINE 
INSTALLATION
The gas line can be brought through either the 
right or the left side of the appliance. The gas 
valve is situated on the right hand side of the 
unit and the gas inlet is on the right hand side 
of the valve.
Note:  If the gas line is being installed from 
the left side, be sure to leave room to 
accommodate servicing of the fan.
The gas line connection may be made of rigid 
pipe, copper pipe or an approved fl ex connec-
tor. (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.
Incorrect fl  ame pattern will have small, prob-
ably yellow fl ames, not coming into proper 
contact with the rear burner or thermopile 
or thermocouple.  
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 
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.
PILOT ADJUSTMENT
Periodically check the pilot fl ames. Correct 
fl ame pattern has three strong blue fl ames: 
1 fl owing around the thermopile, 1 around 
the thermocouple and 1 fl owing across the 
burner (it does not have to be touching the 
burner).
Note: If you have an incorrect fl ame pat-
tern, contact your Regency dealer 
for further instructions.
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" posi-
tion.
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.
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.
