NOTICE

IMPORTANT MESSAGE: SAVE THESE INSTRUCTIONS

The R520* & R620* Power Vent replaces must be installed

in accordance with these Instructions. Carefully read all the

instructions in this manual rst. Consult the Local Gas Branch to

determine the need for a permit prior to starting the installation.

It is the responsibility of the installer to ensure this replace is

installed in compliance with the manufacturers instructions and

all applicable codes.

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"/10" 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.

Electrical Installations must conform to the local codes or, in

the absence of local codes, to the current version of Canadian

Electrical Code, CSA C22.1.1

• Installations in the USA must conform to the local

codes or in the absence of local codes to the current version

Due to high operating temperatures, this appliance should be located out of traffic &

away from furniture and draperies.

Children and adults should be alerted to the hazards of the high surface temperature,

which could cause burns or clothing ignition.

Young children should be carefully supervised when they are in the same room as the

appliance.

Clothing or other flammable materials should not be placed on or near the appliance.

CAUTION

Section A: Before You Begin



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.
