Vertical runs of this system which pass through ceilings require the
use of ONE (1) ceiling restop at the hole in each ceiling through
which the vent passes.
Position a plumb bob directly over the center of the vertical vent
component and mark the ceiling to establish the center point of the
vent. Drill a hole or drive a nail through this center point and check
the oor above for any obstructions such as wiring or plumbing
runs. Reposition the appliance and vent system, if necessary, to
accommodate ceiling joists and/or obstructions.
Cut an appropriate sized hole through the ceiling, using the center
point previously marked. See Figure 36. Frame the hole with framing
lumber the same size as the ceiling joists. See Figure 36.

Installing Support Brackets
A horizontal pipe support MUST BE used for each 3 feet of
horizontal run. The pipe supports should be placed around the pipe
and nailed in place to framing members. There MUST BE a 3 inch
clearance to combustibles above ue pipe and elbows and 1 inch
clearance on both sides and bottom of the ue pipe to combustibles
on all horizontal pipe sections and elbows.
Vertical runs of this vent systems must be supported every 4 feet
above the appliance ue outlet by wall brackets attached to the
vent pipe and secured with nails or screws to structural framing
members.

Installing Firestops
Firestops are required for safety whenever the vent system passes
through an interior wall, an exterior wall, or a ceiling. These restops
act as a rebreak heat shield and as a means to insure that minimum
clearances are maintained to the vent system.
Horizontal runs in the vent system which pass through either interior
or exterior walls, require the use of wall restops on both sides of
the wall through which the vent passes.
Cut an appropriate sized hole in wall. See Figure 35. Position
restop on interior side of wall for hole.
Attention: Wall restop hole is off-set towards bottom of wall
opening. Secure with nails or screws. Continue the vent run through
the restop. See Figure 35.
Attention: Horizontal venting through a wall requires a wall
thimble on the interior side of the wall above the pipe.
