Millivolt and electronic models come standard

with a manually-modulated gas valve; ﬂame appearance and heat output can be controlled at the gas valve. The BTU inputs for these appliances are shown in Table 1.

Gas Pressure Requirements

(All Models)

Gas pressure requirements are listed in Tables 2 and 3.

Test gauge connections are provided on the front of the gas control valve, identied IN for the inlet and OUT for the manifold side (see Figures 3 and 4).

Propane tanks are at pressures that will cause

damage to valve components. Verify that the

tanks have step-down regulators to reduce the

pressure to safe levels.

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).

Burn-in Period

During the rst few res in 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 BURN-IN PROCESS. THE ODOR AND HAZE EMITTED DURING THE BURN-IN PROCESS CAN BE QUITE NOTICEABLE AND MAY SET OFF A SMOKE DETECTOR.

NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.

Oriﬁce Sizes

(Sea Level to High Altitude – All Models)

These appliances are tested and approved for installation at elevations of 0–4500 feet (0–1372 meters) above sea level using the standard

burner orice sizes (marked with an asterisk

(*) in Table 4, below).

For elevations above 4500 feet, contact your

gas supplier or a qualiﬁed service technician.

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,

• changing the burner orice 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 CAN/CSA-B149.1 codes - latest

edition.

Install the appliance according to the regulations

of the local authorities having jurisdiction and, in the USA, the National Fuel Gas Code NFPA 54 / ANSI Z223.1 - latest edition or, in Canada,

the CAN/CSA-B149.1 - latest edition.

NOTE: Flame appearance will diminish 4% per thousand feet of altitude.

IMPORTANT NOTE!

A white ﬁlm may develop on the glass enclosure panel during the ﬁrst few ﬁres as part of the burn-in process.

The first few times you use the fireplace, clean the glass after each use (AFTER THE GLASS HAS COMPLETELY COOLED); otherwise, the white ﬁlm will bake onto the glass and become difficult to remove.

See “Clean Glass Enclosure Panel” on Page 10.

OPERATION AND CARE OF YOUR APPLIANCE

WARNING

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.

AVERTISSEMENT

Les jeunes enfants devraient être surveillés étroitement lorsqu’ils se trouvent 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

Fireplace gas controls are located in the lower control compartment under the ﬁrebox (see Figure 1). Remove the control compartment door to access the controls.

To remove the control compartment door:

Gently pull upward and forward on the door

panel; then slide the panel, rst to one side and then to the other, until the door tabs clear

both holes (see Figure 2).

To reinstall the control compartment door:

Insert one of the door panel side tabs into its corresponding hole in the control compartment opening (see Figure 2); then insert the other side tab. Lift upward on the door panel; then gently push the top edge forward and down

into the grooves in the brackets until it locks

into place.

Appliance Controls

Operation of millivolt and electronic gas control systems differs. Before lighting and

operating your appliance, determine whether you have a millivolt or electronic appliance,

and then familiarize yourself with the location of the Gas Control Valve and Gas Shut-Off Valve on your speciﬁc appliance.

• For general control location, see Figure 1.

• For MILLIVOLT appliances, see Figure 3

for a detailed illustration of the SIT Millivolt Gas Control Valve.

• For ELECTRONIC appliances, see Figure 4 for a detailed illustration of the Dexen Electronic Gas Control Valve.

Lighting the Appliance

• Detailed MILLIVOLT appliance lighting instructions are on Pages 22 and 23 and

also on the label attached to the gas control valve.

• Detailed ELECTRONIC appliance lighting instructions are on Pages 24 and 25 and also on the label attached to the

gas control valve. Also see “Lighting an Electronic Appliance During a Power Outage,” below.

LIGHTING AN ELECTRONIC APPLIANCE

DURING A POWER OUTAGE

1. Install (2) “D” batteries in battery holder.

2. Light the appliance according to the instructions on Page 24.

3. Operate the appliance normally.

4. After power is restored, remove the batteries.

Note: To prevent batteries from draining prematurely, do NOT install batteries until needed (e.g., during a power outage or if operating the appliance solely with batteries).

ON/OFF Control

Available ON/OFF control options for both MILLIVOLT and ELECTRONIC models include a unit-mounted ON/OFF switch (shown in Figure

1), a wall switch, or a remote control system.

See the “Accessory Components” section in this manual for details.

Note: To prevent excessive resistance in burner circuit (which can cause burner operation problems), wire only one burner control switch to the valve.

Adjusting Flame Height

After lighting the appliance, rotate the Flame Height Adjustment Knob to adjust the ﬂame in

a variable range from “LOW” to “HI” (manual adjustment only; no remote options).

• For MILLIVOLT appliances, see Figure 3.

• For ELECTRONIC appliances, see Figure 4.

CONTROLS FOR OPTIONAL OUTSIDE COMBUSTION AIR KIT

An optional outside combustion air system may be used with these appliances to provide supplemental combustion air from outside the

home during appliance operation. If used, the outside combustion air kit must be installed

before the ﬁreplace is framed and enclosed in the ﬁnished wall.

The Outside Air Control Lever for this type of system is standard on all models (see Figure

5); however, do NOT operate the Outside Air Control Lever if the complete system is NOT installed.

When a complete outside supplemental com-

bustion air system is installed, the installer will

remove the securing screw from the control lever on the LEFT side of the ﬁreplace opening (see Figure 5).

If the securing screw has NOT been removed,

and you have reason to believe your ﬁreplace has a complete outside supplemental combus- tion air system, contact your dealer or distributor to have your appliance inspected.

IMPORTANT: Do NOT assume your ﬁreplace has a complete supplemental combustion air system, and do NOT operate the Outside Air Control Lever unless you have veriﬁed with your dealer or distributor that a complete system is in place.

The hand-operated outside air control lever is located on the lower LEFT side of the ﬁreplace opening. See Figure 5.

To open the outside air shutter, open the bottom control access panel, reach into the control compartment, and pull the outside air control

lever all the way out. The outside air shutter should be fully open when the ﬁreplace is in use and completely closed when the ﬁreplace is not being used. Closing it when not in use will greatly reduce the amount of outside cold air entering the dwelling through the ﬁreplace.
