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. 
Use only approved venting components. See 
Approved Vent Components on Page 2.
These fi replaces must be vented directly 
to the outside.
The vent system may not service multiple 
appliances, and must never be connected to a 
fl ue 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.

tighten cover plate screws could 
result in leakage of fl ue 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 fl ue 
products into living space.
