The restrictor plate included in the fireplace components packet can be installed as either a large or small restrictor, depending on your specific venting configura-
tion.
There are several factors which can affect proper draft of the vent system and the burner operation of a fireplace. Installing a restrictor may be necessary to re-
solve the problem, even though it may not be required under „normal conditions‟.
IMPORTANT: DO NOT INSTALL IF THE VENTING CONFIGURATION IS AT THE MINIMUM REQUIREMENTS!
Use the small restrictor for straight vertical terminations between 10' and 15' and the large restrictor is used for straight vertical terminations between 15' and 40'.

IMPORTANT: RE-INSTALL THE EXHAUST BAFFLE AFTER RESTRICTOR INSTALLATION IS COMPLETE. DO NOT OVER TIGHTEN THE NUTS!
