Please review the Pre-Installation Overview on Page 4 for general
information on preparing for a successful installation of your
replace.
The PL42DF* replace may be installed in any location that maintains
proper clearances to air conditioning ducts, electrical wiring and
plumbing. Safety, as well as efciency of operation, should be
considered when selecting the replace location. Select a location
that does not interfere with room trafc, has adequate ventilation
and offers an accessible path for Direct Vent installation.

Section 1: Installation Overview

The install requirements of your replace are dependent on several
factors. Gas line location, electrical connection, gas line type and
decorativesurroundoptionscanplayintotheinstall.Thesefactors
should be considered when determining framing and layout of
your replace.
Note: four sided surrounds will require a raised installation.
Frame in the enclosure for the unit with framing materials. The
framed opening for the assembled replace is 42" wide, x 42" high
x 21 7/8" deep, see Figure 2 .
NOTE: When constructing the framed opening, please ensure
there is access to install the gas line when the unit is installed.
See Figure 21.

Section 2: Framing & Clearances

Clearances
When installing a shelf over the top of the replaces, the following
guidelines must be adhered to:
For Rear Vent applications, the minimum clearance is 0" from the
rear of the replace to a wall, or any combustible materials, and
9" clearance from the top of the replace to the underside of any
combustible shelf materials.
For Top Vent applications, the minimum clearance is 0" from the
rearoftheunit to a wall,oranycombustible materials, and 171/2"
to the underside of any combustible shelf materials.
1” clearance is maintained on sides and bottom of vent runs and
2” above horizontal vent runs to any combustible material.

Installing The Standoffs
To avoid elevated mantel temperatures, all PL42DF* gas
replaces are required to have the supplied standoffs installed.
The replace is supplied with two standoffs. Bend and install these
standoffs on top of the replace ensuring that the height of the
standoff maintains a 7 1/2" clearance.

such that it provides the shortest vent run possible. Should it be
impossible to ensure that the termination is the highest point or
to meet the venting guidelines laid out below please contact your
Montigo dealer to discuss power venting options.
NOTES FOR PLANNING VENTING:
Venting can originate from the unit through the top or
through the rear
Venting can terminate through the roof or through an
exterior wall.
Refer toAppendixA- Termination Locations to ensure the
planned termination location is acceptable.
Once the termination location has been established, refer
to the appropriate section below for installation details
All replaces shipped from the factory are Top vent.
Silicone application is NOT required when joining Montigo
vent pipes and components. Note: Images are shown without screens for clarity purposes.
However, your replace should not be operated without proper
installation of screens.

Section 3-2-1: Venting Layout
Selection of components and details of venting lay out should
adhere to the following guidelines:
The maximum termination point is 32’ above the replace
(NOTE: if the maximum termination height is used, the ame
pattern may be affected).
The Vertical termination must be a minimum 2’higher than
where the termination exits the roong materials, (asphalt
shingles, cedar shakes, etc). This distance should be
measured from the high side of the roof slope where the
ue ashing intersects the roong materials. (see Figures
9 to 9c).
Terminationlocationmustbeaminimum6’fromamechanical

Foramoredetaileddiagramofallowedterminationlocations,
seeAppendixA.
Amaximum of two offsets (each offset is made up of 2-90°
bends) may be made for vertical vent runs.
Firestops must be installed as required by National & local
codes
Ensure all horizontal runs are supported with a minimum
of 3 supports per 10’of venting.

1). Installation of Termination with built in frame
A Termination with a Built-In Frame is installed during framing of
a structure.
1. Frame the termination opening to 11" x 11".
2. Install exterior sheathing to the structure framing.
3. Fasten the termination to the sheathing using a minimum of 4 screws.

5). Installation of a termination shield for Vinyl Siding
The VSS Termination shield is installed when the exterior of a
structure is clad with Vinyl siding. It is placed directly above, and
on-center with the termination.
2). Installation of termination frame at time of framing
Terminations with a MSR frame allow the installation of the frame
prior to installation of the termination.
1. Frame the termination opening to 12" x 12".
2. Secure the MSR Frame to the exterior sheathing of the structure.
3. FastentheterminationtotheMSRFrameusingaminimumof4screws.

2. Secure the BSR Frame to the exterior sheathing of the structure.
3. FastentheterminationtotheBSRFrameusingaminimumof4screws.
1. Frame the MOSR opening to 12" x 12".
2. Fasten the MOSR frame to the interior side of the studs,
concrete, or nished wall construction using a minimum of 4
screws.
3. Insert the termination into the MOSR frame as shown here,
(from the inside) and attach to the MOSR by installing a min.

Installing Heat Guards over Terminations is recommended in
installations where the termination is located within 7' feet above
grade, or above a pedestrian walkway, and may be Required by
code in Public areas.
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.

CPI [Continuous Pilot Ignition] / IPI [Intermittent
Pilot Ignition] Jumper Cable Installation
“Why use CPI mode”?
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
building, 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. This Jumper Cable gives the Remote
ControltheabilitytooperatetheCPI /IPIswitchandsetthe
unit to operate in either condition. 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 using the appliance.
The difference between IPI and CPI:
IPI(IntermittentPilotIgnition)Mode: isafuelsavingmode
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.
