OPERATION AND CARE OF YOUR APPLIANCE

Young children should be carefully supervised when they are in the
same room as the appliance. Toddlers, young children and others
may be susceptible to accidental contact burns. A physical barrier is
recommended if there are at risk individuals in the house. To restrict
access to a fireplace or stove, install an adjustable safety gate to keep
toddlers, young children and other at risk individuals out of the room
and away from hot surfaces.
Les jeunes enfants devraient être surveillés étroitement lorsqu'ils se trou-
vent dans la même pièce que l'appareil. Les tout petits, les jeunes enfants
ou les adultes peuvent subir des brûlures s'ils viennent en contact avec
la surface chaude. Il est recommandé d'installer une barrière physique
si des personnes à risques habitent la maison. Pour empêcher l'accès à
un foyer ou à un poêle, installez une barrière de sécurité; cette mesure
empêchera les tout petits, les jeunes enfants et toute autre personne à
risque d'avoir accès à la pièce et aux surfaces chaudes.

Gas Controls/Control Compartment
Access
Operation of millivolt and electronic gas
control systems is different. Before lighting
and operating your appliance, determine
whether you have a millivolt or electronic
appliance.
The gas controls can be found behind the lower
access panel.
To open the panel, press the upper right corner
of the panel until the spring-loaded magnetic
catch is released. Then gently pull the panel
forward to release the left magnetic catch and
allow the panel to swing down to open.
On millivolt systems, the piezo igniter, HI/LO
flame adjustment knob, pilot and main gas ON/
OFF control knob, and gas valve (Figure 1) are
located behind the lower access panel.
On electronic systems, the hi/lo flame
adjustment knob and gas valve are located
behind the lower access panel. To remove
the lower access panel, slide the hinge pin on
the left side of the panel to the RIGHT until it
disengages from the left corner post hole. Pull
the panel diagonally to the LEFT, away from
the fireplace.
To ease panel replacement, press the spring-
loaded catches to temporarily lock them in
their retracted position, and then close the
panel.
Refer to Figure 1 for access to the gas control
valve. Millivolt appliances will be fitted with the
gas control valve shown in Figure 2.
Appliances with electronic systems will be fitted
with the electronic valve shown in Figure 3.
Familiarize yourself with the gas control valve
that your appliance uses.
