High Elevation
This unit is approved for altitude 0 to 4500 ft.
(CAN1 2.17-M91).
Gas Line Installation
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.
NOTE: A shutoff / dante valve should be supplied
in or near the unit (or as per local codes) for ease
of servicing this appliance.
IMPORTANT: Always check for gas leaks with a
soap and water solution or gas leak detector. Do
not use open flame for leak testing.
Pilot Adjustment
Periodically check the pilot flames. Correct 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).
Note: 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.
Gas Pipe Pressure Testing
The appliance must be isolated from the gas sup-
ply 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 unit 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" pres-
sure tap(s) using a 5/16" ID hose.
4. Turn the unit on with the remote or wall switch
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
unit, disconnect the hose and tighten the screw
(clockwise) with a 1/8" flat screwdriver. Note:
Screw should be snug, but do not over tighten.
