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 3.45 kPa. Disconnect piping from
valve at pressures over 3.45kPa.
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 suitable wide
flat screwdriver.
3)
Attach manometer to "IN" and/or "OUT" pressure
tap(s) using a suitable ID hose.
4)
Turn the unit on with the remote or manual
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.
NOTE:
All the adjustments must be carried out in
the following order:
Remove the modulator plastic cap (A) using
needle nose pliers.
Maximum pressure:
Turn the unit ON to its highest
input rating. Screw in the nut (B) to increase the
outlet pressure and screw it out to decrease it. Use
a 10 mm wrench.
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.

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).
HIGH ELEVATION
This unit is approved for altitude 0 to 1372m.
GAS LINE
INSTALLATION
Since some municipalities have additional local
codes it is always best to consult with your local
authorities.
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 approved shutoff valve should be
supplied in or near the unit (or as per local
codes) for ease of servicing this appliance.

NOTE: The outlet pressure must be set to
maximum 2.49 kPa for both LP/ULPG and 0.87
kPa for NG.
Minimum pressure:
Remove one of the cables co
nected to the electric modulator. While holding the
nut (B) with a wrench, screw in the screw (C) to
increase the pressure and screw it out to decrease
it. Use a screwdriver 6x1 blade.
After carrying out all adjustments, block the setting
screws with paint, taking care not to obstruct the
breather orifice of the pressure.
Put back the modulator plastic cap.
WARNING:
To ensure the correct operation of the
modulator it is necessary that the plastic cap (A) is
returned to its original location.
NOTE: The outlet pressure must be set to
minimum 1.6 kPa. for both LP/ULPG and
0.4 kPa for NG.
6)
Turn on gas supply and plug in power cord.
7)
At the end of all setting and adjustment opera-
tions, check electrical installation and gas leaks.
8)
Check operation of flame control.
9)
Check for proper flame appearance and glow
on logs.
10)
When finished reading manometer, turn off the
unit, disconnect the hose and tighten the screw
(clockwise) with a suitable flat screwdriver.
Note: Screw should be snug, but do not
over tighten.

Installer Notice:
These instructions must be left with
the appliance.
NOTE: Do not screw in nut too far. If no pressure
increases after two full terms, place manometer
on inlet test point on gas valve and check flow-
ing inlet pressure.
