REFIT THE WINDOW
1.
Hook the top of the window frame over the firebox
top front edge.
2.
Secure the window unit in place by refitting two
knurled screws at the bottom corners of the frame.
8.
CHECK OPERATION OF CONTROLS
Check ignition, valve control and thermostat settings as
described in the lighting instructions section of this manual.
9.
CHECK SYSTEM PRESSURE
The appliance is preset to give the correct heat input with the
gas for which it is designed.
For input adjustment, the gas supply pressure to the appliance
must be between the figures shown below.
SUPPLY PRESSURES
Model 736XN – Natural Gas
Maximum
10.5”w.c.
Minimum
5.0”w.c.
Model 736XP - Propane
Maximum
14.0”w.c.
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
/
2
psig (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
/
2
psig (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 1
1
/
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.
DO NOT LET THE APPLIANCE BE OPERATED
WITH INCORRECT VENTING
