performed by a qualified installer, service agency or
gas supplier.A professional service person should be
contacted to inspect this fireplace annually. Make it a
practice to have all of your gas fireplaces checked
annually. More frequent cleaning may be required due
to excess lint and dust from carpeting, bedding
material, etc.
6. Control compartments, burners and air passages in
this fireplace should be kept clean and free of dust and
lint. Make sure the gas valve and pilot light are turned
off before you attempt to clean this fireplace.
7. The venting system (chimney) of this fireplace should

venting system should be cleaned.
8. Keep the area around your fireplace clear of
combustible materials, gasoline and other flammable
vapor and liquids. This fireplace should not be used as
a drying rack for clothing, nor should Christmas
stockings or decorations be hung on or around the

coal, paper or cardboard, etc.) be used in this fireplace.
10. The flow of combustion and ventilation air must not be
obstructed in any way.
11. When the fireplace is installed directly on carpeting,
vinyl tile, or any combustible material other than
wood, it must be installed on a metal or wood panel
extending the full width and depth of the fireplace.
12. This fireplace requires adequate ventilation and
combustion air to operate properly.
13. This fireplace must not be connected to a chimney flue
serving a separate solid fuel-burning fireplace.

IMPORTANT:
PLEASE READ THE FOLLOWING CAREFULLY
Remove any plastic from trim parts before turning the
fireplace ON.
It is normal for fireplaces fabricated of steel to give off some
expansion and/or contraction noises during start up and/or
cool down cycles. Similar noises are found with a furnace
heat exchanger or car engine.
It is not unusual for your Vermont Castings, Majestic
Products gas fireplace to give off some odor the first time it
is burned. This is due to paint curing and undetected oil
from the manufacturing process.
Please open all windows to ensure your room is well ventilated.
It is recommended that you burn your fireplace for at least
ten (10) hours the first time you use it. If the optional fan kit
has been installed, place the fan switch in the “OFF”
position during this time.

A hearth is not mandatory; however, for aesthetic
purposes, we recommend installing a
noncombustible hearth that projects out 12” (305
mm) or more from the front of the fireplace.
Cold climate installation recommendation:
When installing this unit against a
noninsulated exterior wall or chase, it is
mandatory the outer walls be insulated
to conform to applicable insulation
codes.
Hearth
Mantels
The height at which a combustible mantel is fitted
above the fireplace is dependent on the depth of the
mantel. This also applies to the distance between the
mantel leg (if so fitted) and the fireplace. For correct
mounting height and width, refer to Fig. 2a and 2b and
the Mantel Chart below.
The fitting of a bay window trim kit does not affect the
distances and reference points referred to in the
diagram and chart.
Noncombustible mantels and legs may be installed at
any height and width around the appliance.
When using paint or lacquer to finish the mantel, such
paint or lacquer must be heat resistant to prevent
discoloration.

Input ratings are shown in BTU per hour and are
certified without deration for elevations up to
4,500 feet (1,370 m) above sea level.
For elevations above 4,500 feet (1,370 m) in USA,
installations must be in accordance with the
current ANSI Z223.1 and/or local codes having
jurisdiction.
In Canada, please consult provincial and/or local
authorities having jurisdiction for installations
above 4,500 feet (1,370 m).
When purging the gas lines, the window
frame assembly must be removed.
The gas pipeline can be brought in through the vent
end of the fireplace as well as the bottom. Knockouts
(to allow gas pipe installation and testing any gas
connection) are provided on the bottom behind the
valve. It is most convenient to bring the gas line in from
the vent end 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. Do not use an
open flame for leak testing.
Gas Line Installation
Noncombustible materials such as brick or tile may be
extended over the edges of the face of the appliance.
DO NOT cover any vent or grille panels.
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.
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. Holes to secure
the unit to the floor are located behind the access
door grille on the left and right sides 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. Drywall (sheetrock) or wood material may be placed
with a zero clearance to the top edges of the
appliance when finishing walls above sides of the
appliance with glass windows. NOTE:
Attach wall
finishing to constructed frame, not the appliance.
5. On 360DVSL and 360DVSR, drywall, wood, or
wood molding may be placed with zero clearance
to the rear wall of the unit, along the vertical edge
formed by the standoffs, to intersection of the rear
wall, to the side wall having the small glass window.
NOTE:
Attach wall finishing to constructed
frame, not the appliance.

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 upstream 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. See the gas
specification for pressure details and ratings.
Isolate or disconnect this or any other
gas appliance control from the gas line
when pressure testing.
DO NOT subject the fireplace valve to
test pressures exceeding
1
/ 2 psi.

The vent chart should be read in conjunction with the
following vent installation instructions to determine the
relationship of the vertical and horizontal dimensions of
the vent system.
1. Determine the height of the center of the horizontal
vent pipe exiting through the outer wall. Using this
dimension on the Sidewall Vent Graph bellow,
locate the point intersecting with slanted graph line.
2. From the point of this intersection, draw a vertical
line to the bottom of the graph.
3. Select the indicated dimension, and position the
fireplace in accordance with same.
Example A:
If vertical dimension from floor of the fireplace is
11 ft. (3.4 m), horizontal run to the face of outer wall
must not exceed 14 ft. (4.3 m).
Example B:
If vertical dimension from floor of the unit is
7 ft. (2.14 m), horizontal run to the face of outer
wall must not exceed 8 1/2ft. (2.6 m).

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 sliding
joints of telescopic vent sections used in the system.
To join the twist lock pipes together, align the beads of
the male end with the grooves of the female end. While
bringing the pipes together, twist the pipe until the
flange on the female end contacts the 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.
NOTE: For ease of assembly, use a lubricant
(Vaseline or similar substance) on male
end of twist lock pipe prior to assembly.

Fig. 19 Locate vent opening on rear wall
STEP 1
Locate and cut vent opening in the rear wall.
When installed as a rear vent unit this appliance may
be vented directly to a termination located on the rear
wall behind the appliance.
• Specific rear vent starter kits must be used in these
applications (see ‘venting components’). The
appliance has been approved for installation flat
against a rear wall (Fig. 18).
• Maximum horizontal distance between the rear of
the appliance and the outside face of the rear wall
is 20 in. (508 mm) (Fig. 18).
• Minimum clearances between any combustible
material and the vent pipe sections are:
Top .................................................... 2” (51 mm)
Sides................................................. 1” (25 mm)
Bottom .............................................. 1” (25 mm)
STEP 3
Measure the horizontal length requirement for the
venting including a 2” (51 mm) overlap, i.e. from the
elbow to the outside wall face plus 2” (51 mm), or the
distance required if installing a second 90˚ elbow
(Fig. 22).
STEP 4
Install the 4” (102 mm) vent to the appliance collar
and secure with 3 sheetmetal screws. Install the 7”
(178 mm) vent pipe to the appliance collar and secure
with three (3) sheetmetal screws. It is not necessary to
seal this connection.
It is critical there be no downward
slope away from the appliance when
connecting the vent or elbow.
STEP 5
Guide vent through the vent hole as you place the
appliance in its installed position. Guide the 4”
(102 mm) and 7” (178 mm) collars of the vent
termination into the outer ends of the venting.
Do not force the termination. If the vent pipes do not
align with the termination, remove and realign the
venting at the appliance flue collars.
Attach the termination to the wall as outlined in the
instruction sheet supplied with the termination.

• If a 90°elbow is used in the horizontal vent run
(level height maintained), the maximum horizontal
vent length is reduced by 36 in. (914 mm) (Fig. 23).
This does not apply if the 90°elbows are used to
increase or redirect a vertical rise.
Example: According to the vent graph (Fig. 17),
themaximum horizontal vent length in a system
with a 7 1/2in. vertical rise is 20 ft. (6.1 m), but if a
90°is required in the horizontal vent, it must be
reduced to 17 ft. (5.2 m).
NOTE: The sum of Dim. A and Dim. B must not
be greater than 17 ft. (5.2 m). See Fig. 23.
Vertical Sidewall Applications
Because it is very important the venting system
maintain its balance between the combustion air intake
and the flue gas exhaust, certain limitations concerning
vent configurations must be strictly adhered to.
•The vent graph (Fig. 17), showing relationship
between vertical and horizontal side wall venting,
will help determine allowable dimensions.
•Minimum clearance between vent pipes and
combustible materials is 1 in. (25 mm) on top,
bottom, and sides, unless otherwise noted.
•When the vent termination exits through
foundations less than 20 in. (508 mm) below siding
outcrop, the vent pipe must flush up with the siding.
•It is best to locate the fireplace in such a way that
minimizes the number of offsets and horizontal
vent length. The horizontal vent run refers to the
total length of vent pipe from the flue collar of the
fireplace to the face of the outer wall.
NOTE: When installing the appliance as a rear
vent unit, the 90˚ transition elbow
attached directly to the rear of the unit is
not included in the following criteria and
calculations. Unless it is specifically
mentioned, this elbow should be ignored
when calculating venting layouts.

•The maximum number of 90˚ elbows per side wall
installation is three (3).
•If a 90˚ elbow is fitted directly on top of the fireplace
flange, the maximum horizontal vent run before the
termination or a vertical rise is 36 in. (914 mm).
•The maximum number of 45°elbows permitted per
side wall installation is two (2). These elbows can
be installed in either the vertical or horizontal run.
•For each 45°elbow installed in the horizontal run,
the length of the horizontal run MUST be reduced
by 18 in. (45 cm). This does not apply if 45°elbows

When it is not possible to meet required vent terminal
clearances of 12 in. (305 mm) above grade level, we
recommend using a starter kit. It allows installation
depth down to 7 in. (178 mm) below grade level.
Measure 7 in. (178 mm) from the center of the
horizontal vent pipe as it penetrates through the wall.
NOTE: Ensure sidewall venting clearances are
observed. If venting system is installed
below ground, we recommend a window
well with adequate and proper drainage.
If installing a snorkel, a minimum 24 in. (610 mm)
vertical rise is necessary. The maximum horizontal run
with 24 in. (610 mm) vertical pipe is 36 in. (915 mm).
The measurement is taken from the collar of the
fireplace (or transition elbow) to the face of exterior
wall. See sidewall vent graph, page 15, for extended
horizontal runs if the vertical exceeds 24 in. (610 mm).
1. Establish vent hole through the wall (Fig. 24).
2. Remove soil to depth of about 16 in. (406 mm)
below base of snorkel. Install window well (not
supplied). Refill hole with 12 in. (305 mm) of coarse
gravel, leaving a clearance of about 4 in. (102 mm)
below snorkel (Fig. 28).
3. Install vent system.
4. Ensure a watertight seal is made around the vent
pipe coming through the wall.
Below Grade Installations
Universal snorkel
Do not backfill around the snorkel. A
clearance of at least 4” (102 mm) must
be maintained between the snorkel and
the soil.
If the foundation is recessed, use recess brackets (not
supplied) for securing lower portion of the snorkel.
Fasten brackets to wall first, then secure to snorkel
with self drilling #8 x 1/2 sheetmetal screws. It will be
necessary to extend vent pipes out as far as protruding
wall face (Fig. 30).

STEP 6
Use appropriate length of pipe section—telescopic or
fixed—and install. The 20” (508 mm) section of pipe
which goes through the wall is packaged with the
7DVSK starter kit, and can be cut to suit if necessary.
Seal vent pipe and firestop gaps with high temperature
sealant to restrict cold air being drawn in around the
fireplace.
STEP 7
Apply high temperature sealant to 4” (102 mm) and
7” (178 mm) collars, or to the termination 1” (25 mm)
away from the crimped end. Guide 4” and 7” collars of
vent terminations into respective vent pipes. Double
check vent pipes to see that they overlap the collars by
2” (51 mm). Secure termination to the wall with screws
provided, and caulk around the wall plate to
weatherproof.
One alternative to screwing the termination directly to
the wallis the use of expanding plugs or an approved
exterior construction adhesive.
Or, you may attach the termination with screws through
the inner body into the 4” (102 mm) vent pipe; however,
for this method, you must extend the 4” (102 mm) pipe
approximately 6” (153 mm) beyond the outer face of
the wall.
Support the horizontal pipes with metal
pipe straps every 3’ (91 cm).
5. Apply high-temperature sealant caulking (supplied)
around 4 in. and 7 in. snorkel collars.
6. Slide snorkel into vent pipes and secure to wall.
7. Level the soil so as to maintain a 4 in. (102 mm)
clearance below snorkel (Fig. 29).

Fig. 32 Maximum elbow usage
• Up to two 45°elbows may be used within the
horizontal run. For each 45°elbow used on the
horizontal level the maximum horizontal length
must be reduced by 18 in. (457 mm).
Example: Maximum horizontal length—
Zero elbows = 10 ft. (3 m)
1 x 45°elbows = 8 1/2ft. (2.6 m)
2 x 45°elbows = 7 ft. (2.1 m)
•A minimum of an 8 ft. (2.43 m) vertical rise.
•Two (2) sets of 45°elbow offsets may be used
within the vertical sections. From zero to max 8 ft.
(2.43 m) vent pipe can be used between elbows
(Fig. 31).
•7DVCS supports offsets (Fig. 34). This application
will require you first determine the roof pitch and
use the appropriate starter kit. See Venting
Components List, pages 22 and 23.
•The maximum angular variation allowed in the
system is 270˚ (Fig. 32).
