Installation
Installing and Framing the Fireplace
The B-Series-DV-2 replaces may be installed in any location that main-
tains proper clearances to air conditioning ducts, electrical wiring and
plumbing. Safety, as well as efciency of operation, must be considered
when selecting the replace location. Try to select a location that does
not interfere with room trafc, has adequate ventilation, and offers an
accessible pathway for Direct Vent installation. Refer to page 5 - Vent
Installation for more information.
The replace dimensions are shown below:
Figure 4. Minimum Corner framing dimensions, using a 45° elbow.

Installation
■ Use only certied Montigo vent components. (Use of other parts will void
the Montigo warranty, and may impede the operation of the replace.)
■ Connect all vent sections using a minimum of three sheet metal screws on
the outer pipe ue.
■ Vent terminations must not be recessed in walls or siding
■Ensure all runs are supported with a minimum of 3 supports per 10’ of venting.
■ Flex vent sections may be stretched up to 50% of their total length (eg. a
24" section may be stretched to 36")
■ Maximum horizontal run for a ex section with no vertical rise is 3 feet.
■ Flex vent sections over 3 feet must fall within the limits set by the venting
graph and must have a minimum vertical rise of 3 inches per foot of ex.
■ Solid vent sections may be cut less than half way from the female end
■ Venting components can be used in any combination of solid/rigid pipe or ex
pipe and in any orientation (Male connectors can face in any direction)
Vent Terminations
Selecting A Termination Location
Choosing your vent termination location will help to determine whether
you need to use a top vent or rear vent replace. Figure 6, below, shows
typical replace locations and the venting options they provide.
For a more detailed diagram of allowed termination locations, see
Appendix A.
Figure 6. Fireplace locations and vent terminations.
Installing The Gas Line
The gas line must be installed before nishing the B-Series DV-2
Fireplace. Natural Gas requires a minimum inlet gas supply pressure
of 5.5" W.C. & a manifold pressure of 3.5" W.C. Propane Gas requires a
minimum inlet gas supply pressure of 11" W.C. & a manifold pressure of
10" W.C. Provision must also be made for a 1/8" N.P.T. plugged tapping
and be accessible for test gauge connection immediately upstream of
the gas supply controls to the appliance. The replace gas connection
and the main operating gas valve is located behind the removable trim
at the bottom of the unit and need only be attached to the gas line with
an approved tting, as required by the applicable installation codes.
• Only use gas shut-off valves approved for use by the state, province,
region, or governing body, in which the appliance is being installed, or
as required by the applicable installation codes.
• Flexible gas connectors must not exceed 3 feet in length, unless it is
allowable within applicable installation codes.
Note: After gas line is connected, each appliance connection,
valve and valve train must be checked while under normal
operating pressure with either a liquid solution, or leak
detection device, to locate any source of leak. Tighten
any areas where bubbling appears or leak is detected until
bubbling stops completely or leak is no longer detected.
DO NOT use a ame of any kind to test for leaks.
Figure 5. Gas line access.
The appliance and its individual shut-off valve must be disconnected
from the gas supply piping system during any pressure testing of that
system at test pressures in excess of 1/2 psig (3.5 kPa).
The appliance must be isolated from the gas supply piping system by
closing its individual manual shut-off valve during any pressure testing
of the gas supply piping system at test pressures equal to or less than
1/2 psig (3.5 kPa).
Vent Installation
This section covers the installation of direct venting and terminations.
Installation Requirements
■ B-Series DV-2 replaces are certied for use with Montigo Standard Series
(4" / 7") venting components.
■ Minimum clearance to combustible construction around the vent pipe
is 1" on all sides, except on horizontal venting where the top of the pipe
must have a clearance of at least 2".
Cautions:
 Vent terminations can be very hot. If the termination is less than 7 feet
above a public walkway, it should be tted with a certied Montigo
Heat Guard. (Part no. PTKOG).
 Do not obstruct, or attempt to conceal the vent termination.
These actions will affect the operation of the replace, and may
be hazardous.
 In heavy snow areas, take extra care to prevent snow buildup
from obstructing the vent termination.
 Use Montigo Vinyl Heat Shield (Part no. VSS) when using on
applications with vinyl siding to guard against possible damage.
WARNING
When installing the replace - gas lines, ttings,
accessories or any other objects cannot impede the
proper movement of the door buckles.

Installing Terminations with Built-In Frames
Installing Terminations with MSR Frames
1. Frame the termination opening to 12" x 12".
2. Fasten the termination to the studs using a minimum of 4 screws.
1. Frame the termination opening to 11" x 11".
2. Fasten the termination to the studs using a minimum of 4
screws.
Installing Terminations with MOSR Frames
MOSR
1. Frame the termination opening to 12" x 12".
2. Fasten the MOSR frame to the interior side of the studs using a
minimum of 4 screws.
3. Insert the termination into the MOSR frame as shown here, and
attach by screwing through the four pilot holes in the termination.

1. Ensure that the two long mounting brackets are facing the bottom
of the termination. (See inset). This will provide more heat protection
at the top of the termination, where temperatures are highest.
2. Attach to the faceplate of the termination using four sheet metal
screws.
Installing Heat Guards over Terminations
Installing The Remote On/Off Wall Switch
The B-Series DV-2's gas valve, located behind the lower trim, may be
connected to a wall switch. The valve will either generate its own power
on a millivolt circuit or draw its power from an AC connection inside
the replace, depending on the model of your unit. Use only low voltage
wire, and DO NOT connect any external power to the remote switch.
Refer to Figure 24, 26, or 30 for wiring requirements.
Note: The switch location must not exceed 30' from the replace.
Heat Shields
Due to high ue temperatures, heat shields are required on all B Series
DV-2 installations (except those with vertical terminations) at the point
where the venting connects to the termination. With the heat shield, vent
clearances can be maintained at 1”.

Installation
Top Vent Venting Runs
For the B-Series DV-2 Top Vent, there are two types of installations:
A) Through-The-Wall Installations and B) Vertical (Through-The-Roof)
Installations.
Through-The-Wall Installations
Before you install any venting, you must determine whether the venting
run will be acceptable. Unacceptable venting can affect the replace's
combustion.
The Venting Graph
Measure the vertical height from the replace hearth to the centre of the
termination and the horizontal run from the from the replace ue collar
to the wall ange of the termination. Plot on the Venting Graph (Fig. 8)
or (Fig.8a) with an 'X'.
If the 'X' falls on or above the top boundary of the shaded area, the
installation is acceptable.
B34DV-2
Example A: (Acceptable Installation)
If the vertical dimension from the hearth is 108" and the horizontal run to
the wall ange of the vent termination is 180", this would be an accept-
able installation.
Example B: (Acceptable Installation)
If the vertical dimension from the hearth is 44" and the horizontal run to
the wall ange of the vent termination is 72", this would be an acceptable
installation.
Example C: (Unacceptable Installation)
If the vertical dimension from the oor of the replace is 60" and the hori-
zontal run to the wall ange of the vent termination is 144", this would
NOT be an acceptable installation.
Figure 8. B34-DV-2 Top Vent Venting Graph
B38DV-2
Example A: (Acceptable Installation)
If the vertical dimension from the hearth is 84" and the horizontal run to
the wall ange of the vent termination is 36", this would be an acceptable
installation.
Example B: (Acceptable Installation)
If the vertical dimension from the hearth is 108" and the horizontal run to
the wall ange of the vent termination is 120", this would be an acceptable
installation.
Example C: (Unacceptable Installation)
If the vertical dimension from the oor of the replace is 72" and the
horizontal run to the wall ange of the vent termination is 84", this would
NOT be an acceptable installation.

Example A: (Acceptable Installation)
If the vertical dimension from the hearth is 84" and the horizontal
run to the wall ange of the vent termination is 30", this would be
an acceptable installation.
Example B: (Acceptable Installation)
If the vertical dimension from the hearth is 108" and the horizontal
run to the wall ange of the vent termination is 120", this would be
an acceptable installation.
Example C: (Unacceptable Installation)
If the vertical dimension from the oor of the replace is 72" and
the horizontal run to the wall ange of the vent termination is 84",
this would NOT be an acceptable installation.
B. Multi-Elbow Installations
For more difcult installation situations, the B-Series DV-2 Rear Vent
may be installed with two - 90° elbows and up to 15' of horizontal run. If
using this installation option, you must adhere to the following guidelines:
Important: Some models are not available to be installed in a rear
vent application. Please refer to the model specications on page
2 of this manual.
 the rst 90° elbow must be placed directly on the ue collar
 you must have a minimum vertical lift of 50" (measured from the
hearth)
 your vent run must fall within the limits set by Figure 20.
Before you install any venting, you must determine whether the venting
run will be acceptable. Unacceptable venting can affect the replace's
combustion.
The Venting Graph
Measure the vertical height from the replace hearth to the centre of
the termination and the horizontal run from the from the replace ue
collar to the wall ange of the termination. Plot on the Venting Graph
(Fig. 20) with an 'X'.
If the 'X' falls on or above the top boundary of the shaded area, the
installation is acceptable.
Figure 20. B-Series DV-2 Multi-Elbow Venting Graph.
NOTES: All dimension lengths for vertical or horizontal runs are
measured from center of the vent pipe.
Venting runs must fall within the limits set by the venting
graph (see Figure 20).

Installation
Finishing Around the Fireplace
Combustible mantels and mouldings may be safely installed over the
top and on the front of the replace provided that they do not project
beyond shaded area shown in Figure 22 or 22a. Side wall clearances
are 3". Combustible surrounds may be installed with 3" clearance to the
side of the replace as shown in Figure 23.
Fireplace Facing
When selecting the nish material for your replace, it is important to
remember the following: THE HORIZONTAL LOUVRES MUST NOT
BE OBSTRUCTED IN ANY WAY - to do so restricts the air supply
for the control compartments and heat exchanger it also prevents
access for servicing controls.
The face of the replace may be painted to match the room decor,
provided you use a heat-resistant paint. Decorative facing must not
extend past the replace opening at all, because it will interfere with
the access to retainers for removal of glass door.
Mantels & Surrounds
NOTE: National Canadian Gas Association mantel test requirements
are for re hazard prevention to combustible materials.
New technology, to meet consumer and government demands for the
wise use of energy, has prompted us to manufacture many models of
replaces which are hot, fuel and energy efcient.
Please be aware; temperatures over the mantel will rise above normal
room temperature and walls above replace may be hot to touch.
Warning:
When covering the upper metal portion of the replace with a non-
combustible material Please Note: The decorative facing materials
may be subject to temperatures in excess of 250° F. This should be
considered when selecting facing materials.
We recommend careful consideration be given to the effects of elevated
mantel temperatures which may be in excess of product design, for
example: candles, plastic or pictures. This can cause melting, deformation,
discolouration or premature failure of T.V. and radio components.

Burner Adjustment SIT NOVA 820
The B-Series DV-2 is equipped with an adjustable burner, allowing you
to raise or lower the ames. To adjust the ames, locate the black knob
marked 'Hi-Lo', in the right of the gas control valve (See Figure 30). The
front burners are not adjustable.
■ To raise the ame height, turn the black knob (located behind the
lower trim) counter-clockwise.
■ To lower the ame height, turn clockwise.
Figure 30. 'Hi-Lo' Adjustment on the B-Series DV-2's SIT Nova 820
Cleaning
When the replace is rst activated, there may be some smoking and
a visible lm may be left on the glass. This is a normal condition, and is
the result of burning of protective coatings on new metal.
■ Glass must be cleaned periodically to remove any lm (which is
a normal by-product of combustion) which may be visible. Film
can easily be removed by removing the door, as shown on page
15. Handle the door carefully, and clean it with non-abrasive glass
cleaners. One of the most effective products is Kel Kem.
■ Silicone seals on inner door during initial ring will "off gas", leaving
a visual deposit of a white substance on combustion chamber walls.
This can easily be removed from the chamber walls using normal
household products.
■ Use a vacuum cleaner or whisk broom to keep the control
compartment, burner, and rebox free from dust and lint.
■ Logs may be cleaned periodically with a vacuum to remove soot or
other contaminates.
Note: B-Series DV-2-I models (electronic ignition) do
not feature hi/lo adjustment.
Burner Adjustment SIT PROFLAME 2 HI-LO
The B-Series DV-2-F is equipped with an adjustable burner, allowing
you to raise or lower the ames. To adjust the ames, locate the black
knob marked 'Hi-Lo', in the right of the gas control valve (See Figure
31). The front burners are not adjustable.
■ To raise the ame height, turn the black knob (located behind the
lower trim) counter-clockwise.
■ To lower the ame height, turn clockwise.
