Installation of Vent Restrictor
A vent restrictor may be needed with this appliance,
install vent restrictor (provided) in the appliance top
flue outlet as shown in Figure 16 (SSDVT-3328 )
or rear flue outlet as shown in Figure 17 (SSDVR-

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 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.
