• For a venting system that extends through

any zone above that on which the connected

appliance is located (except for one and two

family dwellings), the vent system shall be

enclosed with an enclosure having a fire

resistance rating equal to or greater than that of

the floor or roof assemblies through which it

passes.

• Design any enclosure to permit inspection of the

system.

• Do not place any type of insulation in any

required clearance spaces surrounding the vent

system.

Vertical Installation Requirements:
a. Seal weather exposed joints of the outer jacket

with foil tape or an exterior grade silicone

sealant.

b. The vent system must terminate at least 3 feet

above the roof line and at least 2 feet higher than

any portion of the building within 10 feet.

c. When terminated at a height of more than 6 feet

the stack must be supported by a support bracing.

The vent should be supported every 10 feet.

d. The total continuous distance of the vent system

from the appliance flue collar to the termination

shall not exceed that specified in the appliance

manufacturer’s installation instructions.

e. In cold climates do not install a condensate drain

on the exterior of the building. Doing so may

result in dangerous icy conditions on surfaces

near the drain and may cause damage to the vent

system and/or the building exterior.

f. Install supports every 10 feet vertically along the

vent pipe route. Vertical supports are required

after every transition to vertical and are required

after every offset elbow. When the vent is free

standing and penetrates a roof/ceiling another

means of support must be used at a second

location. Refer to the Vertical Supports section

in this manual.
