Step 3. Install The Vent System; Vent Restrictor Installation - Superior SSDVST-CNM Installation Instructions Manual

Step 3. INSTALL THE VENT SYSTEM

These instructions should be used as a guideline and do not supersede
local codes in any way. Install vent according to local codes, these instruc-
tions, 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 Compo-
nents, Page 2.
• These fi replaces must be vented directly to the outside.
The vent system must 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 enclosure (such as a chase). There is
no requirement for inspection openings in the enclosure at any of the
joints in the vent pipe.
