Fig. 13– Securing the fireplace
VENTING – HORIZONTAL
Install the vent system according to the instructions
included in the venting kit received with the fireplace.
1. With the unit in the desired location, check to
determine if wall studs or roof rafters will obstruct the
venting system when attached. If this is the case, you
may want to adjust the location of the unit or consult
with your framing contractor for options in adjusting the
framing.
2. To properly assemble the Simpson pipe and fittings on
a direct vent system, Mill-pac brand sealant must be
placed between the inner collars of the pipe (see figure
14). Slip the pipe together and twist to lock. After the
pipe is assembled. Carefully wrap the outer seam with
aluminum tape (or seal with silicone). An airtight seal
must be created.
NOTE: All pipe joints must be sealed with Mill-pac
sealant and aluminum tape or Silicone.
Fig. 14– Applying Sealant
NOTE: Horizontal runs must be supported every
three feet. Wall straps should be used for this support.
3. A 10” x 10” square hole must be cut in the exterior
wall. The centerline of this hole should align with the
centerline of the horizontal pipe. Cut and frame the 10”
hole to support the venting (see figure 24).
NOTE: The vent must have a 1/4 inch rise for each 1
foot of run towards the termination. NEVER allow
the vent to run downward. This will cause high tem-
peratures and may cause a fire.
NOTE: The location of the horizontal vent termina-
tion on an exterior wall must meet all local and na-
tional building codes. See page 8 of this manual for
proper terminal locations.
