for Vertical Venting Application
The primary purpose for the vent restrictor is to regain
flame height under certain venting conditions as
outlined below.
NOTE: The joints of the inner pipe (flue pipe) must be
taped with 550°F or higher temperature metal adhesive
tape that meets the requirements of F.A.R. 25.853(a).
High temperature sealant milpack or stove cement of
550°F or higher could be used instead. The joints of
The outer pipe (fresh air pipe) must be taped with
315°F or higher temperature metal adhesive tape or
the use of high temperature milpack or stove cement
would be applicable. When using the unitized 30°, 45°

or 90° elbows, apply 1/4" bead of high temperature,
550°F or higher, sealant (milpack or stove cement) to
the joint of the inner pipe (flue pipe) and the straight
section as it is impossible to be taped. The outer pipe
must be taped with 315°F high temperature metal
adhesive tape for proper sealing.
For vertically venting either propane or natural gas
units, with vertical vent heights of 12' (3.7m) or greater,
(measured from the top of the flue collar) the restrictor
plate as supplied with this unit should be used. (Fig. 28)
