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.

For vertical venting configurations that include a minimum vertical rise of 12’ (3.7 m) and a maximum horizontal offset of 10’ (3 m) the 4¹⁄₂” restrictor plate supplied with this unit should be used. The fresh air restrictor plate could be adjusted to the setting #3 (DVT44IN Only). (Fig. 28) Refer to Pages 25 & 26, Figures 35 & 37 for restrictor plate installation and fresh air restrictor plate adjustment.
