5.9. Vent requirements
Always maintain the required 1” clearance (air space) to combustible materials to prevent a fire hazard. Do
not fill air spaces with insulation.
The gas ZC-fireplace and vent system must be vented directly to the outside of the building and never be at-
tached to a chimney serving a separate solid fuel or gas-burning appliance. Each direct vent gas appliance
must use it’s own vent system.
This ZC-fireplace is equipped only for altitudes: 0-2000 ft. (0-610 m) in USA, In Canada 0-4500 ft. (0-1370 m).
When the vent passes through a wall, a wall thimble is required. When the vent passes through a ceiling, a support
box or fire stop is required. When the vent passes through the roof, a roof flashing and storm collar are required. Fol-
low the instructions provided with the vent system, (From Duravent®) for installing of these items
.
For the vent system use Simpson Duravent model GS direct vent system
only
.
For the nearest supplier call 800 835 4429.
Follow the installation instructions included with the vent system.
Apply high-temperature silicone to the inner and outer pipe before assembling the sections (on the male, upper sec-
tion). This seals the inner pipe from the outer pipe. Slide the sections together and turn ¼ turn until the sections lock
in place. Install three metal screws through each joint to lock the outer section in place (See the instructions included
with the vent for further details).
NOTE: You may screw the first section of the vent to the insert / ZC-fireplace without silicone.
Horizontal sections require a ¼” rise every 12” of travel.
Outer vent diameter = 6 5/8”, inner vent diameter = 4”.
Horizontal sections require non-combustible support every 36” (e.g. use plumbing tape).
5.10. Vent damper adjustment
There is a damper system built into the insert / ZC-fireplace in order to control the flow rate of exhaust gases. This
ensures proper flames for the wide variety of vent configurations. Depending upon the vent configuration, you may be
required to adjust the damper within the insert / ZC-fireplace, and it should be done before connecting the venting
system to the insert / ZC-fireplace.
Consult the vent run specifications on page 30 to 35 to determine which adjustment is needed for the actual vent con-
figuration
