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.
These fireplaces are designed, tested and
listed for operation and installation with,
and only with, Secure Vent™ (SV 4.5) Direct
Vent System Components, Secure Flex™
Flexible Vent Components manufactured by
Security Chimneys International. These
approved vent system components are la-
beled for identification.
DO NOT use any
other manufacturer's vent components with
these appliances. These fireplaces must be
vented directly to the outside.
The vent system may not service multiple appli-
ances, 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.
Preparing the Appliance Vent Collar on
D-500/600/800 Series (Combined Top
and Rear Vent) Models
Each of the unit's two vent collars are sealed
with a cover plate and a seal plate and gasket.
The cover, and seal plate and gasket must be
removed from the vent collar being used.

Figure 13 for top vent usage and
Figure 14 for rear, and the following steps to
prepare the appropriate collar for use.
From the vent collar being used, remove the
four screws securing the vent seal plate and
gasket. Remove and discard the seal plate and
gasket.
When the top vent collar is being used, from
inside the firebox, loosen the two screws in the
keyhole slots of the cover plate and remove the
remaining two cover plate securing screws.
Remove and discard the cover plate. Reinstall
and securely tighten all four screws.
When the rear vent collar is being used, from
inside the firebox, remove the two screws
securing the lintel to the rear wall of the fire-
box, then remove the lintel. Remove the four
cover plate securing screws.
