BEFORE YOU START:
Installation Checklist
■ Determine the desired install location of your replace.
■ See Section 1, Dimensions and refer to the Framing
Section 2 for details.
■ Select your type and location of your Power Vent run:
Roof Mounted (EPVRR) or Wall Mounted (EPVRW).
■ Your termination location should be selected to provide
the most efcient vent run.
■ Lay out the Vent run; calculating the required elbows
and straight runs of 5"/8" ex or rigid pipe.
■ Refer to the Section 3, "Venting" for details.
■ Montigo supplies 20' of low voltage wire, which can be
spliced to a maximum of 100' with wire of equal quality.
This wire CANNOT run in conduit with any other wire.
■ Refer to Section 4, for Wiring Details.
■ The gas connection is located on the bottom right side
(pilot burner side) of the replace.
■ Refer to local codes and guidelines for installation
requirements.
■ Refer to Section 5, "Installing the Gas Line" for details.
■ Installation and repairs should be done by a qualied
contractor and must conform to:
• Installations in Canada must conform to the local
codes or in the absence of local codes to the current version
of Natural Gas and Propane Installation Code, CSA B149.

Introduction to the R-Series Fireplace:
The complete system will require a rebox, a power vent module,
an electrical control panel, and a vent system. The appropriate vent
system will connect the rebox to the power vent module and will be
placed in a vertical or horizontal location. The R-Series replace
is not a heat efcient replace and should not be used with a
thermostat to heat your home. This product is a re feature and
should only be used to enhance the ambiance of the room. Please
review the Installation Checklist on Page 4 for general information on
preparing for a successful installation of your replace.
Install location:
The R-Series 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, 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 Power Vent installation.
Basic Operation:
The gas control components of this replace are located in the bottom
of the rebox below the burner system. All models are supplied with
a Honeywell smart valve gas control and do NOT have a variable
ame control. There are two air switches that control the gas control
system, located in the bottom of the rebox. These gas valves and
pressure switches communicate with the electrical control panel
through a ten conductor cable supplied with the replace.
To operate the replace, Montigo supplies 20' of low voltage wire
from the electrical control panel. Connect the two wire harnesses
to a standard single pole ON/OFF switch to the location of your
choice. You may extend these wires up to 100' in length with a wire
of equal quality.
The  are classified under power vented fireplace systems.
Under no circumstances can thse models be installed without a Power Vent Module.

Back framing the Fireplace
NOTE: Maintain a 1" clearance around the throat (projection at the front of the replace that holds the glass door) when installing 2x4s
for back framing.
Step 1). Cut and install one 2x4 to t horizontally under the replace throat.
Step 2). Cut and install required quantity of short ller 2x4's to t vertically under the horizontal piece.
Step 3). Cut and install four vertical 2x4's. Place 2 on each side of the replace throat.
Step 4). Install supplied steel header 1" above the throat. Attach steel header to vertical 2x4's as shown in gure 5.
Step 5). Cut and install one horizontal 2x4 below the top frame.

Section 3: Venting
Montigo supplies a variety of power venting options. The location of
the power vent should be selected and laid out to provide the most
efcient possible run to an external wall or through the roof.
Notes For Planning Venting:
Section 3-1: Converting to Rear Vent
R-Series units are shipped for Top Vent installations. Follow the
instructions to convert unit for Rear Vent installation.
Section 3-1-1: Converting the Flue
1. Remove the Rear ue cover with gasket (5" and 10") on
the ue outlet, as shown in Figure 7. ENSURE YOU DO
NOT DAMAGE THE FIBRE GASKETS.
2. Remove the Top ue collar (5" and 10") on the ue outlet,
as shown in Figure 7. ENSURE YOU DO NOT DAMAGE
THE FIBRE GASKETS.

■ R-Series replaces are Power Vent Designated.
■ Venting originates from the top or rear of the unit.
■ Venting can terminate through the roof or exterior wall.
■ For a detailed diagram of allowed termination locations, see
Appendix A.
■ Once the termination location has been established refer to
the appropriate section for installation details.
■ All replaces are shipped Top Vent from the factory.
■ Ensure there is a minimum vent run of 2' of straight vent pipe
before the power vent, except for straight rear vented installs.
■ Follow the chart on page 15 or page 19 for maximum vent run
and maximum elbows.
3. Install the removed Rear ue cover (5" and 10") to the Top
Vent outlet. Fasten the cover with included hardware, as
shown in Figure 7a.
4. Install the collars (5" and 10") to the rear vent outlet using
the included hardware, as shown in Figure 7a.
5. Proceed to Section 3-1-2: Converting Pressure Sensing
Tube and Air Bafe.

Section 3-1-2: Converting the Pressure Sensing Tube
and Air Bafe
When the R320*/R420* is converted from Top Vent to Rear Vent,
the pressure sensing tube must be removed and replaced with
supplied Rear Vent pressure sensing tube and air bafe must be
relocated as described below.
1. Remove two screws from the air bafe installed over the Top
Vent from inside the rebox. Once air bafe is removed, replace
the two screws back into the same position.
Note: Not all models are equipped with an air bafe. Only convert
if available.
2. Remove Top Vent pressure sensing tube but loosening the
compression nut with a 1/2" wrench.
3. Position the supplied Rear Vent pressure sensing tube as
4. Install air bafe over Rear Vent from inside the rebox with two
screws provided at the Rear Vent.
shown in Figure 9a. Hand tighten the compression nut by
hand and then a half-turn with a wrench.
Do not over tighten.
