WARNING: Improperly set restrictor setting can cause overheating issues which can lead to
building fire.
It may be necessary to adjust the exhaust restrictor in order to control combustion quality and flame
appearance. There are six different restrictor settings.
Determine what restrictor setting you require using the vent graphs in “

. The restrictor is set to 1 when the flat edge of the dial is vertical (see Figure 66).
Rotate the dial counter-clockwise to increase the restriction level successively until the appropriate setting is
achieved. When the flat edge is horizontal the restrictor level is at its maximum (see Figure 65). The proper
setting is crucial for an efficient burn and best possible flame appearance.
It may be necessary to deviate from the recommended setting as different altitudes and climates can vary
the operation of the appliance. With LP fueled appliances, it is always a good idea to offer slightly less
restriction for higher altitudes to reduce the risk of sooting over an extended period.
