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 .

If your millivolt appliance is equipped with an

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.
