Step 3. Install the Vent System

General Information

These instructions should be used as a guide- line and do not supersede local codes in any way. Install vent according to local codes, these instructions, the current National Fuel Gas Code (ANSI-Z223.1) in the USA or the current standards of CAN/CGA-B149.1 and -B149.2 in Canada.

Useonlyapprovedventingcomponents. See Approved Vent Components on Page 2.

These fireplaces must be vented directly to the outside.

The vent system may not service multiple appliances, and must never be connected to a flue serving a solid fuel burning appliance. The vent pipe is tested to be run inside an enclosing wall (such as a chase). There is no requirement for inspection openings in the enclosing wall at any of the joints in the vent pipe.

WARNING

Failure to reinstall and securely tighten cover plate screws could result in leakage of flue products into the living space. Vent cover plate and vent seal plate must remain securely installed on unused vent collar. Failure to do so could result in leakage of flue products into living space.
