Burner Air Shutter Adjustment Procedure

To adjust the flame, position the air shutter to the

nominal setting

(

Figure 29

)

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.

When satisfied that the appliance operates

properly, proceed to finish the installation.

Leave the control knob/lever in “ON” position

and turn the remote switch “OFF.” Replace the

refractory access panel.

WARNING

•

Air shutter adjustment should

only be performed by a quali-

fied professional service tech-

nician.

CAUTION

•

Soot will be produced if the

air shutter is closed too much.

Any damage due to carboning

resulting from improperly

setting the air shutter is not

covered under the warranty.

•

The air shutter door and nearby

appliance surfaces are hot.

Exercise caution to avoid

injury while adjusting flame

appearance.

Burner Air Shutter Adjustment Procedure

Step 10. BURNER ADJUSTMENTS

Flame Appearance and Sooting

Proper flame appearance is a flame which is

blue at the base and becomes yellowish-orange

in the body of the flame. When the appliance

is first lit, the entire flame may be blue and will

gradually turn yellowish-orange during the first

15 minutes of operation. After 15 minutes of

operation, if the flame is blue, or if the flame is

orange with evidence of sooting (black tip), the

air shutter opening may need to be adjusted.

If the air shutter opening is closed too far, 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 lack of combustion air entering

the air shutter opening. To achieve a warm

yellowish-orange flame with an orange body

that does not soot, the shutter opening must be

adjusted between these two extremes.

Air Shutter Adjustment Guidelines

• If there is smoke or soot present, first

check the log set positioning to ensure that

the flames are not impinging on any of the

logs. If the log set is properly positioned

and a sooting condition still exists, then the

air shutter opening should be increased.

• If there are offsets in the vent system, the air

shutter opening may need to be increased.

• An appliance operated with the air shutter

opened too far, may have flames that appear

blue and transparent. These weak, blue and

transparent flames are termed anemic.

• Propane models may exhibit flames which

candle or appear stringy. If this is present and

persists, adjust the air shutter to a more open

position, then operate the appliance for a few

more minutes to ensure that the flame normal-

izes and the flames do not appear sooty.

The following chart is provided to aid you in

achieving the correct air shutter adjustment

for your installation.
