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.
Incorrect flame pattern will have small, probably
yellow flames, not coming into proper contact with
the rear burner or flame sensor.

Ignitor
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.

c. Minimum pressure: Remove one of the
cables conected to the electric modulator.
While holding thenut (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.
d. After carrying out all adjustments, block
the settingscrews with paint, taking care
not to obstruct the breather orifice of the
pressure.
e. Put the plastic modulator cap back.

Installer Notice:
These instructions must be left with
the appliance.
NO
TE
• A approved shutoff valve should be sup-
plied in or near the unit (or as per local
codes) for ease of servicing this appliance.
Access is required to the flex connection
where joined to copper.
NO
TE
• If you have an incorrect flame pattern,
contact your Regency® dealer for further
instructions.
NO
TE
• 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.
All the adjustments must be carried out in the
following order:
a. Remove the modulator plastic cap (A) using
needle nose pliers.
b. 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.
NO
TES
• 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
flowing inlet pressure.
• The outlet pressure must be set to
maximum 2.49 kPa for both Pro-
pane/ULPG and 0.87 kPa for NG.
W
ARNING
• To ensure the correct op-
eration of the modulator it is
necessary that the plastic cap
(A) is returned to its original
location.
NO
TE
• The outlet pressure must be set
to minimum 1.6 kPa. for both Pro-
pane/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.
