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.

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).
