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 CSA B149.1 installation code.
For U.S.A. installations, follow local codes and/or
the current National Fuel Gas Code, ANSI Z223.1.
Use approved fittings with copper or flex connec-
tors. Always provide a union so that gas lines can
be easily disconnected for servicing. Flare nuts
for copper lines and flex connectors usually meet
this requirement.
Always check for gas leaks with a soap and
water solution or gas leak detector. Do not use
open flame for leak testing.
A shutoff / dante valve should be supplied in or
near the unit (or as per local codes) for ease of
servicing this appliance.
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 touch the burner).
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
During pressure testing of the gas supply piping
system at pressures equal to or less than 1/2 psig.
(3.45 kPa), close the appliance's manual shutoff
valve to isolated it from the gas supply. Disconnect
the piping from the 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.
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 within the limits
specified on the safety label.
6. When finished reading the manometer, turn off
the unit, disconnect the hose, and tighten the
screw (clockwise) with a 1/8" flat screwdriver.
Screw should be snug, but do not over tighten.
