Regency Horizon HZ54EPV Gas Fireplace

INSTALLATION

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

fl at 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 specifi ed on the safety label.

6) When

fi nished reading manometer, turn off the

gas valve, disconnect the hose and tighten the
screw (clockwise) with a 1/8" fl at screwdriver.
Note: Screw should be snug, but do not over
tighten.

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 fl ex connectors use only
approved fi ttings. Always provide a union so
that gas lines can be easily disconnected for
servicing. Flare nuts for copper lines and fl ex
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 fl ame for leak testing.
