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).
Gas Line Installation
The gas line is brought through the right 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.
The gas line connection may be made of rigid pipe,
copper pipe or an approved flex 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 flex connectors use only
approved fittings. Always provide a union so that
gas lines can be easily disconnected for servicing.
Flare nuts for copper lines and flex 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 flame for leak testing.
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 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.
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, turn off the
gas valve, disconnect the hose and tighten the
screw (clockwise) with a 1/8" flat screwdriver.
Note: Screw should be snug, but do not over
tighten.

ote: If you have an incorrect flame pattern,
contact your Regency
®
dealer for further
instructions.
Incorrect flame pattern will have small, probably
yellow flames, not coming into proper contact
with the rear burner or flame sensor.
Flame Pattern
Periodically check the pilot and main burner
flames. Correct pilot flame pattern has two
strong blue flames: 1 flowing around the flame
sensor and 1 flowing across the burner (it does
not have to be touching the burner).
