NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.
Test gauge connections are provided on the
front of the millivolt gas control valve, identi-
fied IN for the inlet and OUT for the manifold
side (see Figure 3 on Page 4). A 1/8" NPT Test
gauge connection is provided at the inlet and
outlet (manifold) ports on the electronic gas
control valve (see Figure 4 on Page 4).
Orifice Sizes - Sea Level to High Altitude
(All Models): These appliances are tested and
approved for installations at elevations of 0-4500
feet (0-1372 meters) above sea level using the
standard burner orifice sizes (marked with an
"*" in Table 7).
At the time of installation, it must be determined
if the appliance needs to be derated. Contact
your local gas supplier for deration requirements
for your area.
Deration - At higher elevations, the amount of
BTU fuel value delivered must be reduced by
either using gas that has been derated by the gas
company or by changing the burner orifice to a
smaller size as regulated by the local authorities
having jurisdiction and by the (USA) National
Fuel Gas Code NFPA 54/ANSI Z223.1 - latest
edition or, in Canada, the CAN1-B149.1 and .2
codes - latest edition.
Burn-in Period
During the first few fires of this appliance there
will be some odor due to the curing of the
paint and burning off of lubricants used in the
manufacturing process.
Depending on your use, the burn-in period may
take a few hours or a few days.
KEEP YOUR HOUSE WELL VENTILATED
DURING THE CURING PROCESS. THE ODOR
AND HAZE EMITTED DURING THE CURING
PROCESS CAN BE QUITE NOTICEABLE AND
MAY SET OFF A SMOKE DETECTOR.
If an optional blower is installed, Do Not turn
it on during the Burn-In period.
A white film may develop on the glass front
during the first few fires as part of the curing
process. The glass should be kept clean during
the first two weeks of use to prevent the film from
baking on (making it very difficult to remove).
See
Cleaning Glass on Page 5.
Gas Controls/Control Compartment
Access
The gas controls can be found behind the control
compartment access door.
Removing Control Compartment Door:
Open the panel by gently lifting it upward and
forwards. Slide the door, first to one side and
then the other, so the tabs clear both of the
locating holes.
On millivolt systems, the piezo igniter, HI/LO
flame adjustment knob, and pilot and main
gas OFF/ON control knob are located below
the glass panel enclosure. The gas valve for
electronic systems is also located below the
glass enclosure panel. See
Figure 1.
Reinstalling Control Compartment Door:
To reinstall, insert the tabs on each side of the
door into the corresponding holes in the control
compartment opening, one side first then the
other. To close, pull the door gently up and
close by pushing forward and pushing the top
edge down into the groves at the brackets until
it locks in place.

OPERATION AND CARE OF YOUR
APPLIANCE
The standard controls for appliance opera-
tion are located behind the panel below the
appliance front glass enclosure panel (see
Figure 1). Optional control switches are also
available (see Page 13 - Remote Wall Switch,
Remote Control or Wall Thermostat).
Operation of millivolt and electronic gas con-
trol systems are different. Before lighting and
operating your appliance determine if you have
a millivolt or electronic appliance. Familiarize
yourself with the gas control valve that your
appliance uses. Refer to Figure 1 for access
to the gas control valve.
These appliances must be isolated from the
gas supply piping system (by closing their
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).
These appliances and their individual shut-off
valves must be disconnected from the gas
supply piping system during any pressure
testing of that system at pressures greater
than 1/2 psig (3.5 kPa).
