Wall Penetration; Flashings And Storm Collars - ENERVEX PowerStack EPSC Installation & Operating Manual

7.2 WALL PENETRATION

This Wall Penetration assembly is primarily used for wall
penetration allowing a section to pass through a wall made
of combustible material. It is used to maintain a minimum
clearance between the combustible wall material and the
vent section passing through the wall.

7.3 FLASHINGS AND STORM COLLARS

Flat Flashings and Adjustable Flashings (5°-30°/32°-45°)
will permit weathering where the vent passes through the
roof structure. The drawing shows a typical application and
features the use of the Storm Collar to weatherproof the
flashing cone/outer casing interface. Please note that the
vent must be allowed to ride vertically through the cone of
the flashing under expansion conditions.
The Storm Collar must be secured and sealed with the
provided sealant to the outer casing of the vent.
Locate as close to the top of the cone of the flashing as
possible so that despite expansion, weatherproofing is
maintained.
