Installing and Framing the Fireplace
The B-Series-DV-2 replaces may be installed in any location that
maintainsproperclearancestoairconditioningducts,electricalwiringand
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 7 - 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-SeriesDV-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
immediatelyupstreamofthegassupplycontrolstotheappliance.
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: Aftergaslineisconnected,eachapplianceconnection,
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).
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, accesso-
ries or any other objects cannot impede the proper
movement of the door buckles.

1. Ensure that the two long mounting brackets are facing the
bottom of the termination. (See inset). This will provide more
heatprotectionatthetopofthetermination,wheretemperatures
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
yourunit. Use only low voltage wire, and DO NOT connect
any external power to the remote switch.
Refer to Figure 24, or 27 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
SeriesDV-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”.

tions: 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 acceptable 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
horizontal run to the wall ange of the vent termination is 144", this
would NOT be an acceptable installation.

 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.

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 servic-
ing 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.

CPI [Continuous Pilot Ignition] / IPI [Intermit-
tent Pilot Ignition] Jumper Cable Installation
on Proame II Basic Board (only available for
SIT Electronic Ignition Systems)
“Why use CPI mode”?
CPI means “Continuous Pilot Ignition” or “Standing Pilot” as
it is commonly known. IPI means “Intermittent Pilot Ignition”,
which only initializes the pilot when you are going to be us-
ing the appliance.
There are several reasons why you may choose to use
CPI mode. When a ue is cold it can be difcult to light
the appliance. It can take a bit of time (particularly on tall
vents) to initialize vent action. This can result in “lifting” or
“ghosting” of the ames during the rst two to three minutes
of operation. It is also possible to encounter times when
the replace fails to light successfully. The replace will
then attempt to re-light a second or third time depending
on prevailing temperatures or altitude. When in CPI mode
the pilot also keeps the system warm. During a “cold” start,
condensation will normally form on the inner glass surface
of the door. This condensation will quickly dry, however, the
condensation tends to run down the glass and cause some
streaking. CPI mode helps to resolve this issue. If CPI
mode is used during the winter months the energy it takes
to run the pilot is partially recovered as heat into the build-
ing, so it does not waste as much energy as running a pilot
in the off season.
A connector is supplied with this unit that can be plugged
into the controller. When the CPI jumper is plugged into the
controller wiring harness the pilot will light and run con-
tinuously. Use the wall switch to turn on the main burner.
Remove the CPI jumper to turn off CPI and return to IPI.
The difference between IPI and CPI:
IPI (Intermittent Pilot Ignition) Mode: is a fuel saving
mode in which the pilot is only used when the main burner
is on.
CPI (Continuous Pilot Ignition) Mode: The Pilot runs
continuously even when the main burner is off.

3). Find the corresponding plug attached to the control
wire harness.
4). The pilot will light and burn continuously.

Reinstalling the screen and door:
To reinstall the door, tilt the top edge towards you and line up the
tabs of the bottom of the door with the slots on the replace. Place
the tabs into the slots, and tilt the top of the door back towards
the replace as far as it will go. Close the latches by holding Part
B onto the groove at the top of the door and pushing Part A down
completely.
To reinstall screen, push the screen back onto the ball studs on
the replace frame.
Installing the Trim & Bafe:
The 6 horizontal trim pieces (3 upper and 3 lower) are purchased
separate from the replace, and must be eld-installed.
Install the trim by placing the top edge of the trim over to the retainer
clips on either side of the replace. Push the bottom edge rmly
inwards and the trim will snap on (See gure 28). Install the upper
trim pieces so that the bafe is resting between the top and middle
piece, as shown below.
The trim piece with the Montigo emblem should be installed on the
lower middle clips with the emblem on the right side.
