When operating your new replace for the rst time,
some vapors may be released due to the burning of
curing compounds used in the manufacture of the
appliance. They may cause a slight odor and could
cause the ames to be the full height of the rebox, or
even slightly higher, for the rst few hours of operation.
It is also possible that these vapors could set off any
smoke detection alarms in the immediate vicinity.

Input ratings are shown in BTU per hour and are

For elevations above 4,500 feet (1,370 m) in USA,
installations must be in accordance with the current
ANSI Z223.1 and/or local codes having jurisdiction.
Heating value of gas in some areas is reduced to
compensate for elevation—consult your local gas utility
to conrm.
For installations at elevations above 4,500 feet (1,370

Model 922ECN is for use only with natural gas. Model
922ECP is for use only with propane gas. The supply
pressure must be between the limits listed above.
The supply connection is 3/8”NPT male thread. The
supply pipe connection is to a exible connector at the
left hand side of the appliance.
These vapors are quite normal on new appliances. We
recommend opening a window to vent the room. After
a few hours use, the vapors will have disappeared and
the ames will be at their normal height.

Choice of Fronts
Note : the 539/549 Fronts require a 540 WDK Wire
Dress Guard with the 922 heater.
Cast Iron Tolerances – Due to the nature of Cast Iron,
dimensional consistency may vary from one unit to the
next and some variation in surface nish and atness is
to be expected. We have done our best to control and
make allowance, however some variation is inevitable.
Closure plates may be required for insert applications
where cast fronts do not cover entire openings.
Standard black 33” high x 36” wide closure plate with
black aluminum extrusion edge is available.

As supplied, this appliance can be installed as an insert
in an existing solid fuel type replace with a chimney
and 4” dia. liner.
The replace must be built in accordance with the
national, state, provincial, or territorial building code
recognised by the authority having jurisdiction, or in
the absence of such a code, in accordance with the
National Building Code of Canada or the National Fire
Protection Association code in the USA. The size of the
replace recess must be sufcient to accommodate the
appliance as shown in gure below.
If previously used for burning solid-fuel, the chimney
must be swept before installation of the appliance. Both
chimney and replace must be checked for soundness

The appliance must be installed on a oor, which is
sufciently at and level to ensure stability. Some
replace constructions have a well in the oor at the
back that may need to be lled in.
Though not mandatory, we recommend that carpet,
soft vinyl or other combustible oor coverings are kept
at least 16” from the front of the appliance since these
types of materials may be affected by the radiant heat
output from this appliance.
The minimum clearances from any combustible
constructions at the front of the appliance are shown
below.

• Optional 975ZCK Zero Clearance Kit must be used
when installing the 922 replace into any application
other than as an insert into an approved solid-fuel
burning replace cavity and chimney. Complete
installation instructions are packed with the 975ZCK.
• The 975ZCK is approved for installation directly on

The pilot burner and electrode unit is at the left end of
the burner.
Push in the lighting knob and turn counter-clockwise
through the “IGN” position to “PILOT”. A spark should
ash across from the pilot electrode to the pilot burner
shield.

The burner is equipped with an adjustable shutter
to control primary aeration. See gure below. The
shutter is factory set at an aeration gap which will
give optimum performance for the vast majority
of installations. In a few unusual installations,
performance may be improved by adjusting the
aeration. The need for adjustment should be
determined by operating the appliance with the ceramic
fuel effects and window installed. See the Final Checks
section in this manual for adjustment details.
The shutter setting is very critical. A small change can
make a substantial difference to the performance.

In some cases, to make gas piping easier, it may
be convenient to remove the burner module from
the rebox—note the location of the gas inlet before
removing the burner module. Remove 2 screws and
pull the burner module partially out of the rebox taking
care not to pull on the wire leads going to vent switch.
With the module partly removed, reach behind the
module with a wrench and loosen the thermocouple
nut at the back of the valve. With the thermocouple
nut loose, pull the vent switch wire leads out of the
brass block at the back of the valve and pull the burner
module the rest of the way out of the rebox. Rough-in
the gas line, valves, or unions and reinstall the burner
module.

Gas Supply Installation
• The appliance is supplied for supply gas connection
at the left hand side of the case. There is also a
gas line access at the rear of the rebox for insert
applications. The zero clearance kit does not have
access at the rear. Supply line connection to the
exible adapter is 3/8”NPT male thread.
Alternatively, the appliance inlet pipe may be
removed and the supply line routed directly to the
control unit. An isolating valve could be tted within
the appliance case.
• Use only new black iron or steel pipes or copper
tubing if acceptable—check local codes. Note that
in USA, copper tubing must be internally tinned for
protection against sulfur compounds.
• Ensure there is a pipe union (or are tting where
permissible) ahead of the burner module for future
servicing. Unions in gas lines should be of ground
joint type.
• The gas supply line must be sized and installed
to provide a supply of gas sufcient to meet the
maximum demand of the appliance without undue
loss of pressure.
• Sealant used must be resistant to the action of all
gas constituents including LP gas. Sealant should
be applied lightly to male threads to ensure excess
sealant does not enter gas lines.
• The supply line should include a manual shut-off
valve to allow the appliance to be disconnected for
servicing.
• Pressure test the supply line for leaks.

• 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 (3.5kPa).
• Failure to either disconnect or isolate the appliance
during pressure testing may result in regulator or
valve damage. Consult your dealer in this case.
• The minimum supply pressure is given in
Specications section of this manual.
• All piping and connections must be tested for leaks
after installation or servicing. All leaks must be
corrected immediately.
• When testing for leaks:
• Make sure that the appliance is turned off.
• Open the manual shut-off valve.
• Test for leaks by applying a liquid detergent
or soap solution to all joints. Bubbles forming
indicate a gas leak. 

• Correct any leak detected immediately.
• The pressure test tapping locations are shown here.
A built-in regulator controls the burner manifold
pressure. The correct pressure range is shown in
the table in the Specications section of this manual.
The pressure check should be made with the
burner alight and at its highest setting. See Lighting
Instructions section for full operating details.
