DAMPER AND OUTSIDE AIR CONTROLS

This appliance is fitted with a manually controlled vent damper. The vent damper should be closed when the appliance is not in use to prevent cold air from entering the home through the venting system. The damper is controlled through the use of a control lever located within the appliance opening at the top center in front of the firebox lintel

(see Figure 5 )

. The control lever snaps into place at either extreme of its range of motion. When locked in position all the way to the right, the damper is open. When locked in position all the way to the left, the damper is closed.

The damper lever actuates a switch, (see wiring diagram) which will prevent the appliance main burner from lighting unless the damper is locked open. The appliance flue damper must always remain open when operating.

WARNING: DAMPER MUST BE IN OPEN POSITION WHEN APPLIANCE MAIN BURNER IS OPERATING.

Many appliances are equipped when installed with an outside (make-up air) vent system that is designed to provide the appliance with outside make-up air for combustion when in operation. The shut-off lever for the outside air system is standard on all appliances but should not be operated if the complete system is not installed. Refer to complete outside air vent system is installed, the installer will remove the cover from the shut-off lever located in the left side of the firebox opening.

If your cover is not removed and you have reason to believe that you have a complete outside air system, contact your distributor to have your appliance inspected for the presence of the complete system. DO NOT assume that you have this system in place.

The hand operated shut-off lever is located in the left side of the fireplace opening behind the screen. To open, pull all the way. The outside air damper should be fully open when the fireplace is in use and completely closed when the fireplace is not being used. This will prevent outside cold air from entering the dwelling.

Maintenance

The appliance and venting system should be thoroughly inspected before initial use and at least annually by a qualified service technician. Proper maintenance and use will require more frequent, less extensive inspections and servicing by the homeowner.

Generally, annual inspections should be performed by a qualified service technician. More frequent periodic inspections and cleanings should be performed by the homeowner. Any discrepancies discovered by the homeowner should result in a call to a qualified service technician to effect the repair or correction.

Refer to the maintenance schedule for maintenance tasks, procedures, periodicity and by whom they should be performed.

IMPORTANT: TURN OFF GAS AND ANY ELECTRICAL POWER BEFORE SERVICING THE APPLIANCE.

Burner Adjustments

Flame Appearance and Sooting

Proper flame appearance is a matter of taste. Generally most people prefer the warm glow of a yellow to orange flame. Appliances operated with air shutter openings that are too large, or with long vertical vent runs, will exhibit flames that are blue and transparent. These weak, blue and transparent flames are termed anemic.

Lintel Extension

Reset

Button

Manual Reset Limit Switch

Right Side Refractory Panel

If the air shutter opening is too small sooting may develop. Sooting is indicated by black puffs developing at the tips of very long orange flames. Sooting results in black deposits forming on the logs, appliance inside surfaces and on exterior surfaces adjacent to the vent termination. Sooting is caused by incomplete combustion in the flames and a lack of combustion air entering the air shutter opening.

To achieve a warm yellow to orange flame with an orange body that does not soot, the shutter opening must be adjusted between these two extremes.

No smoke or soot should be present. Reposition the log set if the flames impinge on any of them.

If sooting conditions exist, the air shutter opening on the main burner can be adjusted. Normally, the more offsets in the vent system, the greater the need for the air shutter to be opened further.

WARNING: AIR SHUTTER ADJUSTMENT SHOULD ONLY BE PERFORMED BY A QUALIFIED PROFESSIONAL SERVICE TECHNICIAN.

Adjustment

To adjust the flame, position the air shutter to the nominal setting

(see Figure 7 ).

Allow the burner to operate for at least 30 minutes. Observe the flame continuously.

If it appears weak or sooty as previously described, adjust the air shutter open or closed until desired effect is achieved.

Note: If the flame still appears anemic with the air shutter closed all the way (usually a result of lengthy vertical venting runs), turn off the appliance, turn off the gas supply, wait for the parts to cool and access the air shutter. The shutter is prevented from actually closing by a tab that is bent over into the opening. Remove this obstruction by bending back. Reassemble and restart the appliance and after 24 minutes reobserve the flame. Adjust the air shutter as described.

TROUBLESHOOTING THE MILLIVOLT GAS CONTROL SYSTEM

Note: Before troubleshooting the gas control system, be sure external gas shut off valve (located at gas supply inlet) is in

the “ON” position.

Important: Valve system troubleshooting should only be accomplished by a qualified service technician.

1. Spark ignitor will not light

pilot after repeated triggering of ignitor button.

2. Pilot will not stay lit after carefully following the lighting instructions.

3. Pilot burning, no gas to burner, Valve knob “ON,” Wall Switch “ON.”

POSSIBLE CAUSES

A. Defective ignitor

(no spark at electrode).

B. Defective or misaligned electrode

at pilot (spark at electrode).

C. Gas supply pressure errant.

D. Pilot orifice plugged. A. Defective pilot generator

(thermogenerator).

A. Damper closed or Damper Switch

defective.

CORRECTIVE ACTIONSYMPTOM

Check for spark at electrode and pilot; if no spark and electrode wire is properly connected, replace ignitor.

Using a match, light pilot. If pilot lights, turn off pilot and trigger the ignitor button again. If pilot lights, an improper gas mixture caused the bad lighting and a longer purge period is recommended. If pilot will not light – check gap at electrode and pilot - should be ³⁄₈" to have a strong spark. If gap measures ³⁄₈", replace pilot

Check inlet gas pressure. It should be within the limits as marked on the rating plate.

Clean or replace pilot orifice. Check pilot flame, it must impinge on thermogenerator

(Figure 9 on page 7)

mum flame impingement on thermogenerator. Ensure that the connection between the valve and thermogenerator are tight and secure.

Ensure damper control lever is locked in the open position, all the way to the right. If the damper control lever is locked in the open position troubleshoot through Steps B., C. and D. below. If the main burner will still not light, determine if the damper switch is defective and replace if necessary.

. Clean and/or adjust pilot for maxi-

(Figure 9 on page 7)

4. Frequent pilot/burner outage

problem.

B. Wall switch or wires defective.

C. Thermopile may not be generating

sufficient millivoltage.

D. Plugged burner orifice. A. Pilot flame may be too low or

blowing (high) causing the pilot/ valve safety to drop out.

NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.

Check wall switch and wires for proper connections. Jumper wire across terminals at wall switch, if burner comes on, replace defective wall switch. If okay, jumper wires across wall switch wires at valve, if burner comes on, wires are faulty or connections are bad.

Check thermopile with millivolt meter. Take reading at thermopile terminals of gas valve. Should read 325 millivolts minimum with optional wall switch “OFF.” Replace faulty thermopile if reading is below specified minimum.

Check burner orifice for stoppage and remove. Clean and/or adjust pilot flame for maximum flame impinge-

ment on thermogenerator

(Figure 9 on page 7)
