Use of Restrictor Plate
for Vertical Venting Applications
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’ (3.7 m) or greater,
(measured from the top of the flue collar) the restrictor
plate as supplied with this unit should be used. (Fig.
26) Also, the fresh air restrictor plate could be adjusted
according to your vent height. (Fig. 26) Refer to Pages
25 & 26, Figures 35 & 37 for restrictor plate installation
and fresh air restrictor plate adjustment.
