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. 
27) Also, the fresh air restrictor plate could be adjusted 
according to your vent height. (Fig. 27) Refer to Pages 
26 & 27, Figures 36 & 38 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 26 & 27,

This Gas Fireplace has been approved for,
• 
Vertical installations up to 40’ (12 m) in height. Up  
to a 20’ (6 m) horizontal vent run can be installed 
within the vent system using a maximum of three 
(3) 90° elbows. (Fig. 29)
• 
A 2’ (610 mm) vertical section must be installed 
before any offset. A maximum of 20’ (6.1 m) horizon-
tal and three (3) 90° elbows may be installed with a 
minimum of 12’ (3.66 m) vertical section above the 
flue collar of the unit. (Fig. 29)
