Vermont Castings, Majestic Products: DVR33
Framing and Finishing
Check fireplace to make sure it is
levelled and properly positioned.
1. Choose the unit location.
2. Place the unit into position and secure it to the floor
with 1.5” (38 mm) screws, or nails. The holes to
secure the unit to floor are located just behind the
access door grille on the left and right side of the
unit.
3. Frame in the fireplace with a header across the top.
It is important to allow for the finished wall face
when setting the depth of the frame.
4. Attach the fireplace to the frame using the adjustable
frame drywall strips (located behind the access
door for shipping). Preset the depth to suit the
facing material of the wall. The strips are adjustable
to 1/2” (13 mm), 5/8” (16 mm), or 3/4” (19 mm).
(Fig. 5)
5. Screw through the slotted holes in the drywall strip
and into predrilled holes in fireplace side. Measure
from face of fireplace to the face of the drywall strip to
confirm the final depth.
Final Finishing
Noncombustible materials such as brick or tile may be
extended over the edges of the face of the appliance.
DO NOT cover the window frame assembly, any
vent, louvre assembly top or louvre assembly
bottom.
If a Trim Kit is going to be installed on the fireplace, the
brick or tile will have to be installed flush with the edges
of the appliance.

Gas Line Installation
When purging the gas lines, the front
glass must be removed.
The gas pipeline can be brought in through the side of
the fireplace as well as the bottom. Knockouts are
provided on the bottom behind the valve to allow for the
gas pipe installation and testing of any gas connection.
It is most convenient to bring the gas line in from the
rear right side of the valve as this allows fan installation
or removal without disconnecting the gas line.
The gas line connection can be made with properly
tinned 3/8” copper tubing, 3/8” rigid pipe or an approved flex connector. Since some municipalities have
additional local codes, it is always best to consult your
local authority and the CSA-B149.1 installation codes.
For USA installations consult the current National Fuel
Gas Code, ANSI Z223.1.

Always check for gas leaks with a mild
soap and water solution applied with a
brush no larger than 1” (25 mm). Never
apply soap and water solution with a
spray bottle. Do not use an open flame
for leak testing.
Do not subject the fireplace valve to test
pressures exceeding 1/2 p.s.i. Isolate, or
disconnect this and any other gas
appliance control from the gas line when
pressure testing.
The gas control is equipped with a captured screw type
pressure test point; therefore, it is not necessary to
provide a 1/8" test point up stream of the control.
When using copper or flex connector use only approved fittings. Always provide a union when using
black iron pipe so that the gas line can be easily
disconnected for burner or fan servicing (Fig. 6). See
the gas specification for pressure details and ratings.

General Information for Connecting Vent Pipes
Crimped End Pipes
Before joining elbows and pipes, apply a bead of high
temperature sealant to the crimped end of the elbow or
pipe.
Join the pipes using a 2” (50 mm) overlap and secure
the joints with three sheet metal screws (Fig. 13). Wipe
off excess sealant.
Canadian Installations:
The venting system must be installed in accordance
with the current CSA-B149.1 installation code.
USA Installations:
The venting system must conform to local codes and/
or the current National Fuel Code ANSI Z223.1.
Only venting components manufactured by Vermont
Castings, Majestic Products may be used in Direct
Vent systems.

Twist Lock Pipes
When using Vermont Castings, Majestic Products
twist-lock pipe it is not necessary to use sealant on the
joints. The only areas of the venting system that need
to be sealed with high temperature silicone sealant
are the collars on the fireplace and termination, and
the sliding joint of any telescopic vent section used in
the system.
To join twist lock pipes together, simply align the beads
of the male end with the grooves of the female end,
twisting the pipe until the flange on the female end
contacts external flange on the male end. It is recommended that you secure the joints with three (3) sheet
metal screws, however this is not mandatory with twist
lock pipe (Fig. 14).
To make it easier to assemble the joints we suggest
putting a lubricant (Vaseline or similar) on the male
end of the twist lock pipe prior to assembly.

Locate and cut the vent opening in the wall.
For combustible walls first frame in opening (Fig. 16).
Combustible Walls: Cut a 10³⁄₈”H x 9³⁄₈” W (265 mm
x 240 mm) hole through the exterior wall and frame as
shown.
Noncombustible Walls: Hole opening should be 7¹⁄₂”
(190 mm) in diameter.
Zero clearance sleeve is only required
for combustible walls.
Step 2
Measure wall thickness, and cut zero clearance sleeve
to proper length; i.e., max. 12” (304.8 mm). Assemble
sleeve to its maximum opening (10
