G. Grilles and Trim

Install optional marble and brass trim surround kits as de- sired. Marble, brass, brick, tile, or other noncombustible materials can be used to cover up the gap between the sheet rock and the appliance.

Do not obstruct or modify the air inlet/outlet grilles. When overlapping on both sides, leave enough space so that the bottom grille can be lowered and the trim door removed.

H. Air Shutter Setting

This appliance has an adjustable air shutter (which con- trols the primary air) factory set for the minimum vertical vent run. If your installation has more than the minimum required vertical vent length, adjustment of the air shutter may be necessary to obtain optimal ﬂame appearance.

This should be adjusted by a qualiﬁed installer at in- stallation.

To adjust air shutter, loosen the wing nut. Close air shutter by pushing the air shutter forward. Care should be taken when adjusting the air shutter so as not to cause the ap- pliance to soot. If sooting occurs the air shutter will need to be opened by pulling the air shutter forward.
