For clearances to combustible materials from the vent pipe, see “MINIMUM CLEARANCE TO
COMBUSTIBLES” section.
For optimum performance it is recommended that horizontal runs have a 1/4" (6.4mm) per rise per 1 ft (0.3m).
All inner exhaust and outer intake vent pipe joints may be sealed using either red high temp silicone sealant
or black high temp Mil Pac with the exception of the appliance exhaust flue collar which must be sealed using
Mil Pac (not supplied).
!
WARNING
DO NOT FILL THE SPACE BETWEEN THE VENT PIPE AND ENCLOSURE WITH ANY TYPE OF
MATERIAL. DO NOT PACK INSULATION OR COMBUSTIBLES BETWEEN CEILING FIRESTOPS.
ALWAYS MAINTAIN SPECIFIED CLEARANCES AROUND VENTING AND FIRESTOP SYSTEMS.
INSTALL WALL SHIELDS AND FIRESTOPS AS SPECIFIED. FAILURE TO KEEP INSULATION OR
OTHER MATERIALS AWAY FROM VENT PIPE MAY CAUSE FIRE.

This application occurs when venting through an exterior wall.
Having determined the correct height for the air terminal
location, cut and frame a hole in the exterior wall as
illustrated to accommodate the
restop assembly.
Dry
t the
restop assembly before proceeding to
ensure the brackets on the rear surface
t to the
inside surface of the horizontal framing.
The length of the vent shield may be cut shorter
for combustible walls that are less than 8 1/2”
(215.9mm)thick but the vent shield must extend the
full depth of the combustible wall.
A.
Assemble the shield to the spacer as shown,
using the 3 shorter screws supplied.
B.
Place the
restop top so that the vent shield covers the top
of the vent within the opening. Ensure that both spacer and
shield maintain the required clearance to combustibles.
C.
Secure the spacer in place using the 4 longer screws supplied. Once the vent pipe is installed in its
nal position, apply sealant between the pipe and the
restop spacer.
