4.4 TEE CAP

Used to close off the unused opening of Tees and branched
elbows where used for cleaning access.
It can also be used as an end cap in horizontal runs, or as an
inspection fitting cover.

4.5 DRAIN TEE CAP

The Drain Tee Cap is used as as a drain for vertical vents.
When not used as a drain the nipple shall be closed off with
a pipe cap supplied by the installer. When used as a drain, a
1" Drain
trap or a valve should be used in the drain line.
Always connect the drain fitting of the Drain Tee Cap to
a suitable drain. This will allow rain entering the vent to
wash down, dilute and remove any corrosive combustion

condensate.

4.6 TAPERED INCREASER/REDUCER

Tapered Increasers are made with a standard side angle of
11° to 26.5° for low pressure losses, and provide an increase
of one, or two sizes.
You can tell the difference between an increase and a
decreaser by the location of the male end (spigot).

4.7 ECCENTRIC INCREASER/REDUCER

The Eccentric Increaser and Reducer serve the same
purpose as the Increaser and Reducer. They are usually
installed in a horizontal part of a vent system, where they
allow for a smooth transition at the lowest part of the run.
They are used in systems where condensate is present
where they allow for easy run off..
