 E21-2 Gas Fireplace Insert

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.

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

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.

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.

 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.

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.

Follow CAN/CGA B149 (in Canada) or ANSI 
Z223.1 (in the USA) requirements, and any 
local codes or regulations of the enforcing 
authority.

Air for combustion is drawn in through the front 
of the unit, therefore, the front of the unit must 
be kept clear of any  obstructions.
