exhaust RestRictoR settings
The S50 has an internal exhaust restrictor that can be adjusted externally. Depending on the venting con-
figuration this may need to be adjusted. The restrictor dial is accessed from the top of the fireplace, below
the top plate (refer to the section “Lifting the Top Plate” on page 13 for instructions). Using a 7/16” socket,
rotate the restrictor CLOCKWISE until the required setting is in-line with the finger catch. Refer to the graphs
in the following sections for approximate restrictor setting. The proper setting is crucial for an efficient burn
and best flame appearance.
It may be necessary to deviate from the recommended setting as different altitudes and climates can vary the
operation of the fireplace. With propane (LP) fueled fireplaces, it is always a good idea to offer slightly less
restriction for higher altitudes to reduce the potential of sooting over an extended period.
*Note: The restrictor is set in the fully open position from the factory.
