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).
