allows the appliance to
sidewall vent through any approved 4” dia. vent
to a remote fan/hood up to 75 feet from the
appliance.
All installations must conform with local codes or, in the
absence of local codes, with the National Fuel Gas Code ANSI
Z223.1 or the Canadian Installation Code CAN/CGA-149.
Only qualified licensed or trained personnel should install the
appliance.
This appliance is not intended for use with a thermostat.
1.3 HIGH ALTITUDE INSTALLATIONS
This appliance has been tested for installation at high altitude
to CAN/CGA 2.17-M91. This standard simulates operation up
to 4500ft.
Natural Gas appliances comply with this standard without
deration of normal rated input.
Propane appliances require a 10% deration over 2000ft.
In Canada, installations above 4500ft. will require approval
of the authority having jurisdiction.
In the USA, the National Fuel Utilization Code specifies that
appliances installed at over 2000ft. altitude shall be derated by
4% per 1000ft. altitude. However, these appliances have been
specifically field-tested for high altitude performance.
Therefore, deration of Natural Gas appliances is not necessary
or recommended for installations up to 7000ft. For Propane
appliances a total deration of 10% for all altitudes above
2000ft. and up to 7000ft. is required. Above 7000ft. derate
Natural gas appliances by 4% for each 1000ft. above 7000ft.
Derate Propane appliances by 4% for each 1000ft. above
7000ft. plus 10%.
1.4 SUPPLY GAS
Model 736XN is for use only with Natural Gas. The natural
gas supply pressure at the appliance inlet connection should be
not less than 5”w.c. and not more than 10.5”w.c.
Model 736XP is for use only with Propane Gas. The propane
supply pressure at the appliance inlet connection should be not
less than 11”w.c. and not more than 14”w.c.
The supply connection to all appliances is 3/8” NPT.
1.4.1 Gas Feed Line
The supply gas feed line should enter the appliance through
one of the openings in the appliance case. Openings are
provided at the back and right side. See figure 3.

Minimum 11.0”w.c.
The burner manifold pressure is controlled by a built-in non-
adjustable regulator. The manifold pressure must be between
the figures below.
MANIFOLD PRESSURES
Model 736XN – Natural Gas
Maximum 3.9”w.c.
Minimum 3.5”w.c.
Model 736XP - Propane
Maximum 9.4”w.c.
Minimum 9.0”w.c.
The manifold pressure should be checked at the pressure test
point which is located on the thermostat unit (see figure 16).
The pressure check should be made with the appliance
burning, the valve control set at “MAX” and the thermostat
control turned to “FULL”.
The appliance and its individual shutoff valve must be
disconnected from the gas supply piping system during any
pressure testing of that system at test pressures in excess of
1/2psig (3.5kPa). The appliance must be isolated from the gas
supply piping system by closing its individual manual shutoff
valve during any pressure testing of the gas supply piping
system at test pressures equal to or less than 1/2psig (3.5kPa).
10. CHECK VENTING EFFICIENCY
A check for correct venting of combustion products must
be made before the installed appliance is left with the
customer. The test can be made before refitting the inner
front unit but the logs and window unit must be in
position.
Check as follows;
1. Ignite the pilot and set the control knob to “MAX”
and the thermostat wheel to “FULL”.
2. Leave the appliance on for 15 minutes then light a
smoke match and insert it inside the left side of the
top opening. Insert the match approximately 11/2”
into the opening. See figure 23.
The installation is satisfactory if smoke is drawn into
the appliance.
3. If the smoke is not drawn into the appliance, inspect
the sealing at the vent connection unit.
4. If the sealing is satisfactory but the smoke is still not
drawn into the appliance, turn the unit off and check
the vent system for the cause of lack of draft. If
necessary, seek expert advice.

supplied with the air holes
of both burners fully open.
The shutters can be pushed
to the right to partially
close the air holes on each
burner. When the shutters
are pushed as far as
possible to the right, the air
holes will be half closed.
For the majority of
installations no adjustment will be necessary. However, in
certain installations (e.g. low Btu value gas or propane with
impurities) it may be necessary to partially close the air holes
of one or both of the burners to obtain the optimal visual
effect.
12. REPLACE THE INNER FRONT
Hook the inner front unit back onto the front frame.
13. FINAL CHECK
1. Recheck the operation of the ignition and control
settings.
2. Instruct the customer how to operate the appliance.

and, if necessary, serviced annually.
14. OPERATING PROCEDURE
For your safety this appliance is fitted with a flame
supervision device which will shut off the gas supply if, for
any reason, the pilot flames go out. This device incorporates a
fixed probe which senses the heat from the pilot flame. If the
probe is cool the device will prevent any gas flow unless the
control knob is held in at the “IGN” position. See the lighting
instructions on the next page.
Open the bottom grill to get access for operating the main
control valve. Close the grill when you have finished
operating the main control valve. The control wheel at the top
right side of the appliance controls the thermostat operating
temperature.
