Framing and Finishing

NOTE: The valve box assembly must be installed in the

same room as the fireplace.

1. Choose the unit location.

2. The unit is shipped with four (4) nailing flanges
mounted to the sides near the front corners. (Fig. 5)

3. Frame the fireplace with a header across the top of
the standoff. (Fig. 6) It is very important to allow for
the finished wall face along with marble, tiles or any

Bend
Line

other noncombustible face finish material desired
when setting the depth of the framing.

4. Attach the fireplace nailing flanges to the frame as
shown in Figure 5.

5. The gas components are located in the control
panel assembly attached to the right side of the unit.
Choose the desired location on the wall or mantel
for the valve box assembly. The conduit length is 5ʼ
(1524mm). (Fig. 7) The framing dimensions for the
box are 12¹⁄₄”L x 9¹⁄₄”W x 5⁵⁄₈”D (311mm x 235mm x
143mm). When the framing for the box is complete,
remove the screws securing the valve box to the
outer casing. Carefully remove the valve box and,
without stressing the conduit, slide the box into the
framed opening. Replace the screws removed from
the side of the outer casing.

Fig. 5 Nailing flanges.

Fig. 7 Valve box assembly location.

6. To secure the valve box assembly to the framing
members, open the box door, remove extension
knob(s). For units with two piece cover plates, re­move the front cover plate by removing the screws
holding the front plate to the second plate. Discon­nect the wires for the pilot indicator and remove the
second plate located at the top of the box.

For units with a one piece cover plate, remove the

valve cover by removing the two (2) screws securing
the valve cover to the box, hold the cover plate with
one hand and disconnect the wires to the switch and
pilot indicator (R models only). NOTE: Do not allow
the valve cover plate to hang from the pilot indicator
wires as this could damage the wires.

Secure the box to the framing through the two (2)

holes at the top and one (1) on each side using
sheet rock screws. (Fig. 8) After framing the box,
replace the wires, the valve cover, the extension
knob(s) in reverse order.

NOTE: The pilot indicator body is labelled +/-, make

sure the positive wire on the pilot indicator goes to
ground and the negative goes to the plug between
the valve and the thermocouple.

7. The U-channel located on the top of the unit as well
as the nailing flanges on the sides that were men­tioned in Step 1, are designed to accommodate non­combustible board (recommended Dura-Rock). They
are positioned 1” (25mm) back from the face of the
unit. NOTE: The U-channel depth can be adjusted
by loosening the hex nut inside the channel.

If marble, tile or any other noncombustible decora

tive face finish material is desired, a 3” (76mm) wide
noncombustible board (recommended Dura-Rock)
is to be nailed to the nailing flanges on both sides
of the unit. Also, 12” (305mm) of noncombustible
board is to be nailed to the front face of the U-chan­nel and the top framing member above the standoff.

Combustible material can then be brought to the

outside edges of the noncombustible board installed
earlier. Any noncombustible decorative face finish
could be brought to the sides and top of the unit and
can cover the framing and sheet rock. If a decora­tive facing is not desired, then the noncombustible
boards must be double thickness and brought flush
with the face of the unit.

(Not provided)

Fig. 9 Typical gas supply installation.

Always check for gas leaks with a mild
soap and water solution applied with a
brush no larger than 1” (25mm). Never ap­ply soap and water solution with a spray
bottle. Do not use an open flame for leak
testing.

The fireplace valve must not be subjected
to any test pressures exceeding 1/2 psi.
Isolate or disconnect this or 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, use only approved fittings. Always
provide a union when using black iron pipe so the gas
line can be easily disconnected for burner servicing. A
union may not be behind a wall. (Fig. 9) See the gas
specifications for pressure details and ratings.

Remote ON/OFF Switch

Do not wire the remote ON/OFF wall switch
for this gas appliance into a 120V power
supply.

The unit is equipped with an ON/OFF rocker switch at
the valve box assembly. If a wall switch is desired, fol­low these instructions.

1. The valve box is equipped with two knockouts at
the top right and left corners. The right knockout is
designed to run the wall switch wires to the valve.
Use Romex connectors when running wires through
the valve box where the knockouts are located.

2. Attach the wire to the ON/OFF switch and install the
switch into the receptacle box.

3. Connect the other end of the wire to the gas control
valve. (Fig. 10)

Electrical Junction Box (E Units Only)

The fireplace, when installed, must be elec­trically connected and grounded in accord­ance with local codes or, in the absence
of local codes, with the current CSA C22.1
Canadian Electrical Code or the national
electrical code ANSI/NFPA No. 70 in the
USA.

It is strongly suggested that the wiring of
the Electrical Junction Box be carried out
by a licensed electrician. The box should
be near the valve box assembly to plug the
cord into.

Ensure the power to the supply line has
been disconnected before commencing
this procedure.

Electronic Gas Control Valve

This appliance may be fitted with a Honeywell ignition
module. The unit is shipped from the manufacturer with
an ON/OFF switch. The ON/OFF switch is located in
the valve box assembly. If desired a wall switch may be
used.

Installation of the remote ON/OFF switch on electronic
ignition units:

1. The valve box is equipped with two knockouts at the
top right and left corners. The right knockout is de­signed to run the wall switch wires to the valve. The
left knockout is designed for wiring the electronic
unit (E model) to 120v with proper grounding. Use
Romex connectors when running wires through the
valve box where the knockouts are located.

2. Attach the wire to the ON/OFF switch and install the
switch into the receptacle box. (Fig. 11)

3. Connect the White wire from the wall switch to the
Black wire from the transformer, using an approved
wire nut or terminal. Connect the Black wire from the
wall switch to the Black wire running from the #6 po­sition of the ignition module, also using an approved
wire nut or terminal.

General Venting

Your fireplace is approved to be vented either through
the side wall, or vertical through the roof.

• Only Vermont Castings, Majestic Products

venting components specifically approved and
labelled for this fireplace may be used.

• Venting terminals shall not be recessed into a wall or

siding.

• Horizontal venting must be installed on a level plane

without an inclining or declining slope.

There must not be any obstruction such as bushes, gar­den sheds, fences, decks or utility buildings within 24”
(610mm) from the front of the termination hood.

Do not locate termination hood where excessive snow
or ice build up may occur. Be sure to check vent termi­nation area after snow falls, and clear to prevent ac­cidental blockage of venting system. When using snow
blowers, make sure snow is not directed towards vent
termination area.

Location of Vent Termination

It is imperative the vent termination be located observ­ing the minimum clearances as shown on following
page.

General Information Assembling Vent Pipes

SK8 Venting Pipes

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 with local codes and/
or the current National Fuel Gas code ANSI Z223.1/
NFPA 54.

Only venting components manufactured by Vermont
Castings, Majestic Products can be used in Direct Vent
systems.

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.

Start by attaching the first vent pipe section to the collar
on top of the fireplace. In order to attach the first pipe
section, it may be necessary to remove the top shield.
Remove four (4) screws securing top shield, install first
pipe section and replace top shield.

Install the pipe as shown in Figure 14. When you get a
good lock, you will hear the pipe clearly snap together.
Once sections are snap-locked in place, it is extremely
difficult to get them apart. Make sure the pipe is firmly
snapped and locked together as each pipe section is
mounted.

When installing elbows, follow the same procedure.
The joints of inner and outer elbow must be taped with
UL approved high temperature metal adhesive tape for
proper sealing. Be sure to always attach straps on up­per elbow to a structural framing member.

For vertical installations, continue installing the pipe as
required until pipe is installed up through the ceiling. At
this point, you must install a firestop spacer.

Horizontal Termination

The vent must rise vertically a minimum of 24” (610mm)
off the top of the unit, before the first elbow. The hori­zontal run may extend up to 20ʼ (6m) and include a
vertical rise of up to 40ʼ (12m). (Fig. 15) Horizontal ter­mination must also meet the criteria shown in Figures
12 & 13.

• Approved vent systems must terminate above and

including the heavy line in Figure 15.

• Two 45° elbows may be substituted for each single

90° elbow.

• With a rise between 2ʼ - 4ʼ, one (1) 90° or two (2) 45°

elbows may be used.

Vertical Termination

A vertical vent system must terminate no less than 12ʼ
(3.66m) and no more than 40ʼ (12m) above the appli­ance flue collar. A 2ʼ (610mm) vertical section must be
installed before any offset. A maximum of 20ʼ (6.1m)
horizontal and three (3) 90° elbows may be installed
with a minimum of 12ʼ (3.66m) vertical section above
the flue collar of the unit. Refer to Page 15, Figure 26
for more information.

A vertically terminated vent system must also conform
to the following criteria:

• No more than three (3) 90° elbows may be used.

• Two (2) 45° elbows may be substituted for one (1)

90° elbow. No more than six (6) elbows may be
used.

• Termination height must conform to roof clearance

as specified in Figure 34.

Sidewall Applications

Since it is very important that the vent­ing system maintain its balance between
the combustion air intake and the flue
gas exhaust, certain limitations as to vent

configurations apply and must be strictly
adhered to.

Use of the Restrictor Plates in

Horizontal Venting Applications

The primary purpose for the vent restrictor plate is to
regain flame height under certain venting conditions as
outlined below.

20006081

Unacceptable vent-

ing configuration

FP1359

For propane unit, fresh air restrictor plate is shipped
from the factory at the #2 setting and can be adjusted
to setting #1 in some applications if needed. Refer to
Pages 20 & 21, Figures 36 & 38 for restrictor plate
installation and fresh air plate setting adjustment.

DVT38 ONLY

When using the horizontal starter vent kit, SK8DVSK,
with liquid propane, do not use the restrictor plate. If
using this vent kit with natural gas, the 3” restrictor plate
may be used. (Fig. 16)

The vent graph showing the relationship between verti­cal and horizontal side wall venting will help to deter­mine the various dimensions allowable.

Minimum clearance between vent pipes
and combustible materials is 3¹⁄₂” (89mm)
on top, 2¹⁄₂” (64mm) on both sides and 1¹⁄₂”
(38mm) on the bottom.

When the vent termination exits through foundations
less than 20” (508mm) below siding outcrop, the vent
pipe must be flush with the siding.

It is always best to locate the fireplace in such a way
that minimizes the number of offsets and horizontal
vent length of vent pipe from the flue collar of the fire­place to the face of the outer wall.

Horizontal plane means no vertical rise exists on this
portion of the vent assembly.

• The maximum number of 90° elbows per side wall

installation is three (3), but must not have two (2)
consecutive elbows in the horizontal plane.

of the unit is required, an elbow and a 1ʼ (305mm)
maximum horizontal run to get through a wall. (Fig.

18)

• 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. (Fig.

19)

• For each 45° elbow installed in the horizontal run,

the length of the horizontal run MUST be reduced
by 18” (45cm). This does not apply if the 45° elbows
are installed on the vertical part of the vent system.
For each 90° elbow installed in the horizontal run,
the length of the horizontal run MUST be reduced by
36” (91cm).

• The maximum number of elbow degrees in a system

is 270°. (Fig. 20)

Example: In Figure 23

Sidewall Installation

STEP 1

Locate vent opening on the wall. It may be necessary
to first position the fireplace and measure to obtain hole
location. Depending on whether the wall is combustible
or noncombustible, cut opening to size. (Fig. 21)

For combustible walls first frame in opening.

Combustible Walls: Cut a 16¹⁄₄”H x 16¹⁄₄” W (413mm
x 413mm) hole through the exterior wall and frame as
shown.

Noncombustible Walls: Hole opening must be 11¹⁄₄”
(286mm) in diameter.

STEP 2

Measure wall thickness and cut zero clearance sleeve
parts to proper length (MAXIMUM 12”/305 mm). As­semble sleeve using #8 sheet metal screws (supplied).
(Fig. 22) Install firestop assembly. (Fig. 31)

Zero clearance sleeve is only required for
combustible walls.

STEP 3

Slide the zero clearance sleeve through the wall and
install the firestop on the inside surface of the wall.
Secure with four (4) #8 sheet metal screws.

Operating Instructions

Glass Information

Only glass approved by CFM Specialty
Home Products should be used on this
fireplace.

• The use of any non-approved replacement glass will

void all product warranties.

• Care must be taken to avoid breakage of the glass.

• Do not operate appliance with glass front

removed, cracked or broken.

• A replacement glass frame assembly (complete

with gasket) is available through your Vermont
Castings, Majestic Products dealer and should
only be installed by a licensed qualified service
person.

Glass Frame Assembly Removal

1. Turn the fireplace OFF (including the pilot).

2. If the unit has been operating allow time for the
components to cool.

3. Using a Phillips screwdriver, unfasten two (2) screws
located at the top of the glass frame. (Fig. 35)

4. Tilt the glass frame at the top away from the unit.
Lift it carefully off the bottom door track and set on
padded surface.

Glass Cleaning

It is necessary to periodically clean the glass. During
start-up, condensation, which is normal, forms on the
inside of the glass. This condensation causes lint,
dust and other airborne particles to cling to the glass
surface.

Also initial paint curing may deposit a slight film on
the glass. It is therefore recommended the glass be
cleaned two or three times with a non-ammonia based
household cleaner and warm water (gas fireplace glass
cleaner is recommended) within the first few weeks of
operation.

After the initial cleaning process the glass should be
cleaned two or three times during each operating
season depending on the environment in the house.

Clean the glass after the first two weeks of
operation.

Restrictor Plates Installation

Refer to Pages 13 & 16 for your venting configuration
and combination of restrictor plate requirement and
fresh air restrictor plate adjustment.

-

Corrective Action

Using a match, light pilot. If pilot lights, turn off pilot and
push the red button again. If pilot will not light - check
gap at electrode and pilot-should be 1/8” to have a
strong spark.

With the control knob in the pilot position, push the
control knob all the way and hold. Check for spark at
electrode and pilot. If no spark to pilot, and electrode
wire is properly connected, replace the battery in the
ignitor module and try again. Refer toMaintenance
Section. If the problem still exists, replace the ignitor
module box.

Check pilot flame. Must impinge on thermocouple/ther

­mopile. NOTE: This pilot burner assembly utilizes both

a thermocouple and a thermopile. The thermocouple
operates the main valve operation (On and Off). Clean
and or adjust pilot for maximum flame impingement on
thermopile and thermocouple.

Turn valve knob to “Pilot”. Maintain flow to pilot; millivolt
meter should read greater than 10mV. If the reading
is okay and the pilot does not stay on, replace the gas
valve. NOTE: An interrupter block (not supplied) must
be used to conduct this test.

Check wall switch and wires for proper connections.
Jumper wire across terminals at wall switch, if burner
comes on, replace defective wall switch.. If okay,
jumper wires across wall switch wires at valve, if burner
comes on, wires are faulty or connections are bad.

1. Be sure wire connections form thermopile at gas

valve terminals are tight and thermopile is fully
inserted into pilot bracket.

2. One of the wall switch wires may be grounded. Re-

move wall switch wires form valve terminals if pilot
now stays lit, trace wall switch wiring for ground.
May be grounded to fireplace or gas supply.

3. Check thermopile with millivolt meter. Take reading

at thermopile terminals of gas valve. Should read
250-300 millivolts (minimum 150) while holding
valve knob depressed in pilot position and wall
switch “Off”. Replace faulty thermopile if reading is
below specified minimum.

Check burner orifices for debris and remove.

Turn valve knob to “On”, place wall switch to “On”

­millivolt meter should read greater than 150mV. If the

reading is okay and the burner does not come on,
replace the gas valve.

Clean and/or adjust pilot flame for maximum flame
impingement on thermopile and thermocouple.

Check the vent terminal for blockage (recycling the flue
gases).

Burner and Burner Compartment

It is important to keep the burner and the burner
compartment clean. At least once per year the logs and
lava rock/ember material should be removed and the
burner compartment vacuumed and wiped out. Remove
and refit the logs as per the instructions in this manual.

Always handle the logs with care as they
are fragile and may also be hot if the
fireplace has been in use.
