E21-3 Gas Fireplace Insert
GAS PIPE
PRESSURE TESTING
The appliance must be isolated from the gas
supply 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. Read manometer.
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
OFFSET FLUE
ADAPTOR
A Offset Flue Adaptor Kit,
Part #532-920
is
available as an accessory to move the fl ue
outlet back for easier liner installations in deep
fi replaces. The offset fl ue adaptor requires the
use of a 3" liner.
VENTING
THE APPLIANCE MUST NOT BE
CONNECTED TO A CHIMNEY FLUE
SERVING A SEPARATE SOLID FUEL
BURNING APPLIANCE.
This appliance is designed to attach to a 4"
diameter type B-Vent or double thickness
approved aluminium fl ex liner.
The fl ue collar of the appliance will fi t inside
a standard vent and may be fastened directly
to the vent by sheet metal screw or a B-Vent,
single wall vent connector.
B-Vent chimneys require a 1" clearance to
combustibles.
A 3" diameter type B-Vent or approved aluminium
fl ex liner may also be used with a 4" to 3" reduc-
ing adapter. Consult venting charts and local
code requirements.
The Regency
®
Insert incorporates its own
internal draft hood, so no additional external
draft hood is required. Check periodically that
the vent is unrestricted and an adequate draft
is present when the unit is in operation.
Before installing the vent system ensure that the
damper plate is locked into the open position
and secure to prevent the damper plate from
falling down and crushing the liner.
The appliance is equipped with a vent safety
shutoff system and a safety control system
designed to protect against improper venting
of combustion products. The appliance will not
function without being connected to a proper
system.
WARNING: Operation of this heater
when not connected to a properly
installed and maintained venting
system or tampering with the vent
shut-off system can result in carbon
monoxide (CO) poisoning and
possible death.
This appliance must not be connected to a
chimney fl ue serving a separate solid fuel burn-
ing appliance.
For best venting performance, we recommend
the following venting rules:
1) Use only certifi ed Type B gas vent or
approved fl ex liner.
2) Follow the vent manufacturer's instructions
and clearance requirements.
3) Observe any local code restrictions, if any,
regarding the installation of gas inserts.
4) Use as few elbows as possible.
5) Keep horizontal lengths as short as possible
and maintain at least an upward slope of
1/4 in. (6.4mm) for every 12 in. (305mm) of
horizontal run.
6) Terminate the vent with a suitable certifi ed
vent cap.
COMBUSTION AND
VENTILATION AIR
WARNING: This appliance needs fresh air
for safe operation and must be installed
with provisions for adequate combustion
