Vent Restrictor
WARNING
: Restrictor adjustment should only be done by a qualified installer.
Only those installations determined to be over-drafting require this adjustment. The best indication of
over-drafting is a hyper-active flame pattern (flames that move too quickly). If the air shutter is
constricted, the flames become short and yellow, yet still very active. Over-drafting may affect the pilot,
but this is not the best way to determine over-drafting. Over-drafting is most likely in tall venting
configurations. Do not over-restrict the vent (this leads to ghosting or lifting flames - reduce restrictor
setting).
The restrictor is adjusted with the face removed. Start with the restrictor in position number 1. Monitor
the flame for 5 minutes before adjusting. Move the restrictor a maximum two positions at a time by lifting
the adjustment plate and moving it until the correct notch falls into the slot on the adjustment bracket (use
a glove if the heater is hot - see illustration below). Monitor the flame for 5 minutes to determine correct
restrictor position and repeat restrictor adjustment if necessary.
Vent Installation
Secure the vent to the fireplace insert and termination kit using screws.
