Restrictor Position (Top Vent Configuration)
• In 99% of DVL Fireplace installations, restrictor adjustment is not necessary. 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. If over-drafting is determined, follow the directions below to
adjust the restrictor. Try position two first. If still over-drafting, try position three.
With the fireplace cool,
reach behind the gas
control valve.
To Access the Restrictor:
