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 (especially if using an “Exhaust Only Re-Line”). Do not over-restrict the vent (this leads to
ghosting or lifting flames - reduce restrictor setting).
Remove the face.

Determine a restrictor position. Start low (move
the restrictor a maximum two positions at a time)
and thoroughly test the heater before adjusting further.
Lift up the adjustment plate and move it so the correct notch falls
into the slot on the adjustment bracket.
