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 detec-
tor. Do not use open flame for leak testing.

Regency Horizon ® HZ54E-11 Gas Fireplace
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).
Burner
Flame Sensor
Pilot
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 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.
