I. Air Shutter Setting

This appliance has an adjustable air shutter (which controls the primary air) factory set for the minimum vertical vent run (see Figure 12.10). If your installation has more than the minimum required vertical vent length, adjustment of the air shutter may be necessary to obtain optimal flame appear- ance. This should be adjusted by a qualified installer at the time of installation.

•If the vent configuration is installed incorrectly, the vent may cause the flames inside the appliance to lift or “ghost,” which is a dangerous situation. Inspect the flames after installation to ensure proper performance. If the vent configuration is correct, yet the flames are lifting or ghosting, shut off the gas to the appliance and contact the dealer.

•Your air shutter is provided at 1/8 in. open for natural gas, 3/8 in. open for propane (30 in./33 in. appliances), and full open for 36 in. and 42 in. propane appliances. In the event soot is accumulating in your appliance, the air shutter should be opened farther. This can be done by opening the control access panel and locating the two wing studs and two wing nuts attaching the valve assembly to the firebox. Remove the wing nuts and wing studs, slide the valve assembly to the left and lower. Rotate the valve assembly horizontally and remove from underneath the appliance. See Figure 12.11.

Note: To avoid damage to the pilot assembly, remove the valve assembly pilot side first. If the valve assembly gasket is damaged, it should be replaced.

•Locate the air shutter mounted on the end of the main burner. Loosen the locking screw, open the air shutter, and retighten the locking screw. See Figure 12.10.

•Replace the valve assembly, wing nuts and wing studs as removed, making sure to line the orifice up with the main burner neck.
