Variable Flame Height Adjustment
( Millivolt Appliances only)
1. All Millivolt appliances are equipped with
a variable gas control valve. Flame height for
these models may be adjusted through a range
between fi xed low and high settings, alternately,
while the appliance is in operation. Adjust
the fl ame height as desired after lighting the
appliance by rotating the variable adjustment
control knob located on the front of the valve
(refer to Figure 3).
2. When lit for the fi rst time, this appliance will
emit a slight odor for an hour or two. This is due
to the “burn-in” of internal paints and lubricants
used in the manufacturing process.
Electronic Appliances -
To light electronic appliances refer to the detailed
lighting instructions found in both English and
French on Pages 22 and 23 of these instruc-
tions respectively. Electronic appliance lighting
instructions may also be found on the pull out
lighting instruction labels attached to the gas
control valve. If your electronic appliance is
equipped with an optional remote wall switch
or remote control kit the appliance main burner
may be turned on and off with the wall switch
or remote control.
If your electronic appliance is not equipped
with a wall switch or remote control, the main
burner must be turned off and on with the gas
control switch. Toggle the switch from ON to
OFF to operate the main burner .

optional remote wall switch or remote control
kit and the pilot is lit, the appliance main burner
may be turned on and off with the wall switch
or remote control.

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 (3.5 kPa).
The appliance and its individual shut-off valve
must be disconnected from the gas supply piping
system during any pressure testing of that system
at pressures in excess of 1/2 psig (3.5 kPa).
These appliances must not be connected to a
chimney or fl ue serving a separate solid fuel
burning appliance.
Any safety guard or screen removed for servicing
the appliance must be replaced prior to operating
the appliance.
Carbon Monoxide Poisoning: Early signs of
carbon monoxide poisoning are similar to the fl u
with headaches, dizziness and/or nausea. If you
have these signs, obtain fresh air immediately.
Turn off the gas supply to the appliance and have
it serviced by a qualifi ed professional, as it may
not be operating correctly.
OPERATION AND CARE OF YOUR
APPLIANCE
Appliance operation may be controlled through a
remotely located optional wall switch. Separate
switches may provide independent control for
the remote controlled fi replace operation (op-
tional equipment).
In lieu of remote or remote wall switch operation,
the appliance must be operated directly through
the controls located on the front of the valve
located within the control compartment which is
located behind the control compartment access
panel below the appliance front glass enclosure
panel. See Figure 1.
Gas Controls/Control Compartment
Access
The gas controls can be found behind the control
compartment access panel. To open the control
compartment access panel, actuate the spring
loaded magnetic catches securing the panel.
First, gently depress the upper right top corner
of the panel until the magnet catch "pops" the
door free. Then, gently pulling the panel forward,
disengage the left magnet catch and allow the
panel to swing down to open.
Operation of millivolt and electronic gas control
systems are different. Before lighting and op-
erating your appliance determine if you have a
millivolt or electronic appliance. See Figure 1
for access to the control compartment.
Millivolt appliances will be fi tted with the gas
control valve shown in Figure 3 on Page 5.
Appliances with electronic systems will be fi t-
ted with the electronic valve shown in Figure
2 on Page 4.
Familiarize yourself with the gas control valve
that your appliance uses.
Millivolt Appliances -
To light millivolt appliances refer to the detailed
lighting instructions found on Page 20 (English)
and Page 21 (French). Millivolt appliance
lighting instructions may also be found on the
pull-out lighting instruction labels attached to
the gas control valve. Refer to Figure 3 on Page
5 for the location of the piezo Igniter.
Millivolt appliances may be fi tted with an optional
burner ON/OFF Rocker Switch. The optional ON/
OFF Rocker switch will be installed in the bracket
just beneath the gas control valve. Once the pilot
is lit, the ON/OFF rocker switch will control the
appliance ON/OFF operation. To operate: Toggle
the switch between its ON and OFF positions.

WARNING
B-Vent appliances are not designed
to operate in negatively pressured
environments (pressure within the
home is less than pressures outside).
Significant negatively pressured
environments caused by weather,
home design, or other devices may
impact the operation of these appli-
ances. Negative pressures may result
in poor fl ame appearance, sooting,
damage to property and/or severe
personal injury. Do not operate these
appliances in negatively pressured
environments.
