Clearances and Installation Requirements (Rear Vent Configuration)
•
3” Clearance above the pipe to combustibles.
• 1-1/2” Clearance below and to the sides of the pipe to combustibles.
•
When vent passes through a wall, the wall thimble is required (included with Kit A or Kit B).
Use the DVL FP Rear Vent thimble when passing through a
wall. NOTE: make sure the firestop is postitioned correctly so
the 3" clearance is allowed above the vent.

Apply high-temperature silicone to the inner and outer pipe
before assembling the sections (on the male section). This
seals the inner pipe from the outer pipe. Slide the sections
together and turn 1/4 turn until the sections lock in place.
Install three metal screws through each joint to lock the outer
section in place (see the instructions included with the vent
for further details).
•
Horizontal sections require a 1/4" rise every 12" of travel
•
Horizontal sections require non-combustible support every
three feet (e.g.: plumbing tape)
Apply a 1/8" (3 mm)
bead of high-
temperature silicone
to the inner and
outer pipe. The
silicone must seal
the inner pipe from
the outer pipe.

Restrictor Position (Rear Vent Configuration)
•
In 99% of DVL Fireplace installations, restrictor adjustment is not necessary. Only those installations
determined to be over-drafting require this adjustment. The best indication of over-drafting is a hyper-
active flame pattern (flames that move too quickly). If the air shutter is constricted, the flames become
short and yellow, yet still very active. If over-drafting is determined, follow the directions below to
adjust the restrictor. Try position two first. If still over-drafting, try position three.
With the fireplace cool,
reach behind the gas
control valve.
To Access the Restrictor:
NOTE: The fireplace is shipped with the
restrictor in position #1 (fully open).
This restrictor is in position 1
(fully open - factory setting).
This restrictor is in position 2.
