Vent Termination

Unit Installation with Vertical Termination

! NOTE: A top clearance of 3" (76 mm) and side bottom clearance of 2" (51 mm) must be maintained, except
when passing through a wall, ceiling, or at the termination where the use of a fire stop or wall thimble reduces
the required clearance to 1 ½" (38 mm) . We recommend building a frame around the fire stop or wall thimble to
give structural rigidity for mounting the termination . See manufacturer's table cutout dimensions for appropriate
sizing for component used .
1 . Maintain the 1 ½" (38 mm) clearances to combustibles
when passing through ceilings, walls, roofs,
enclosures, attic rafter, or other nearby combustible
surfaces, ensuring that the use of a fire stop or wall
thimble is used as noted above . Do not pack clearance
space with insulation . Consult the relevant section for
the maximum vertical rise of the venting system and
the maximum horizontal offset limitations .
2 . Set the gas appliance in its desired location . Drop a
plumb bob down from the ceiling to the position of
the appliance flue exit, and mark the location where
the vent will penetrate the ceiling . Drill a small hole
at his point . Next, drop a plumb bob from the roof
to the hole previously drilled in the ceiling, and mark
the spot Diagram 2 where the vent will penetrate the
roof . Determine if ceiling joists, roof rafters or other
framing will obstruct the venting system . You may wish
to relocate the appliance or to offset to avoid cutting
load-bearing members .
3 . A firestop spacer must be installed in the floor or
ceiling of every level .
4 . Assemble the desired lengths of pipe and elbows .
Ensure that all pipes and elbow connections are in the
fully twist-locked position and sealed .
! NOTE: For best results and optimum performance
with each approved venting system, it is highly
recommended to apply "Mill-Pac" sealant to every inner
pipe connection . Failure to do so may result in drafting
or performance issues not covered under warranty .
5 . Cut a hole in the roof centered on the small drilled
hole placed in the roof in Step 2 . The hole should be of
sufficient size to meet the minimum requirements for
clearance to combustibles of 1 ½" (38 mm) . Slip the
flashing under the shingles (shingles should overlap
half the flashing) as per Diagram 2 .
6 . Continue to assemble pipe lengths .
! NOTE: If an offset is necessary in the attic to avoid
obstructions, it is important to support the vent pipe
every 3 feet (0 .9 meters), to avoid excessive stress on
the elbows, and possible separation . Wall straps are
available for this purpose .

The upper half of the flashing is installed
under the roofing material and not nailed
down until the chimney is installed . This
allows for small adjustments .
