Introduction to the RP-Series Fireplace:
The complete system will require a rebox, a power vent
termination, an electrical control panel, and a vent system.
There are 3 different power vent terminations available
depending on your installation requirements. Each power vent
requires a control cable to be installed between the power vent
and the control panel. Review the installation sequence on
page 7 for general information on preparing for a successful
installation of your replace. The RP-Series replace is not
intended to be used as a primary heat source and should
not be connected and operated with a thermostat switch.

Install location:
The RP-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. A differential pressure switch
is located at the bottom of the rebox monitors airow and
controls the gas valve. A thermal switch located on the top of
the rebox acts as a secondary safety system and shuts down
the replace in the event that normal operating temperatures
exceeded. These components communicate with the electrical
control panel through a six 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.
This replace is equipped with lights which need to be wired
through a wall switch or dimmer circuit as shown in the
schematic.
ON/OFF control of this appliance can also be performed using
an optional remote control available from your Montigo dealer.

Fuel Gas Code, ANSI Z223.1/NFPA 54. Electrical Installations must
conform to the local codes or, in the absence of local codes, to the
current version of the National Electrical Code, ANSI/NFPA 70.
See Appendix B for installation within the State of Massachusetts.
Fuel Type
Verify that your replace is compatible with your available gas
type. Natural Gas or Propane shown by "N" or "L" in your model

When planning your installation, take into consideration
the area around the appliance where combustible building
materials cannot be placed. Regardless of the type of
construction used, or if the unit is a raised installation or any
other consideration or construction illustration else where in this
manual, combustible materials cannot be placed in this region.
This illustration depicts to a greater extent the minimum size of
the replace chase that this appliance requires. You can also
use this diagram to double check the clearances once the unit
has been installed, prior to closing the replace enclosure.
Non-combustible installations must maintain the replace
enclosure cavity volume minimum and a 1" clearance around
the rebox.

Non-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 8.
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.
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.
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.
Side wall clearances are 6". Combustible surrounds may be installed
with 6" clearance to the side of the replace as shown in Figure 9.

Installation of Electrical Supply
The RP620* is supplied with an external electrical control box pre-
wired by the factory. The control box is connected to the replace
with a 30 foot long 6-conductor cable that will communicate with
the replace. Extension cables are available through your Montigo
Dealer only.
A 20ft low voltage black / white cable is provided for connection
to a single pole on/off switch. The length of this cable can be
extended up to a length of 100ft using a cable of equal or greater
capacity. This system operates on 24VAC. Do not connect this
switch circuit to an external power source.
Optional remote control available through your Montigo Dealer.
Do not use third party remote controls without the approval from
Montigo.
Section 4: Wiring
Installing the Fireplace Control Box
Install the Fireplace Control Box in an accessible location. The
location should be where maintenance, adjustments and service
may be made easily.
Conduit & Wiring clearances
Connect the power vent harness as outlined in the previous section.
Ensure that the proper clearances are maintained for the wiring and
conduit. When installing the wiring it must never run above the vent
run and it must be at least 1" clear of all venting.
1” Clearance
Wire
Note: If any of the original wire supplied with the appliance is
replaced, it must be with the same or it's equivalent.
Installations in Canada must be electrically grounded in
accordance with CSA C22.1 Canadian Electrical Code Part 1
and/or Local Codes.
Installations in the USA must be electrically grounded in
accordance with local codes or, in the absence of local codes,
with the National Electrical Code, ANSI/NFPA 70.

The manifold outlet pressure is set from the factory to the
appropriate pressure but should be veried.
To check pressures, gas valves have a provision to remove a
1/8” MPT plug and to be tted with a hose barb.
Montigo requires a service shut off valve be located in an
accessible location to isolate the appliance.
Only install gas shut-off valves approved for use by the state,
province, or other governing body in which the replace is
being installed.
GAS CONNECTION
See Figure 15 below for location of gas line access.
Flexible gas connectors must not exceed 3 feet in length, unless
allowable within local regulations.
Connect incoming gas line to the 1/2" MPT gas inlet.
Purge all air out of gas line before connecting.
Check appliance connection, valve and valve train under
normal operating pressure with a commercially available leak
check solution.
DO NOT USE A FLAME OF ANY KIND TO TEST FOR LEAKS.

Vent Configurations
Vent configurations can include vertical sections, horizontal sections, elbows, flex and/or rigid vent
sections. The maximum length of any vent run is 80'. Follow the rules outlined below to determine your
specific vent options. All venting is to be 5" inner and 8" outer sizing. Because this appliance intended to
only be installed with a power vent termination, vertical and horizontal runs can be calculated in the same
manor.
Flexible venting does not flow quite as well as rigid pipe, so a factor needs to be applied, making the total
allowable vent run shorter than rigid pipe.
* Not for rigid elbows used in between flex sections
Venting Calculation Rigid Vent Flex Venting
Maximum Vent Run - Rigid 80' total length 60' total length
