Understanding the Basic Operation
Residential R320-ST & R420-ST fireplace
The control compartment of this fireplace is located in the bottom
of the fireplace right below the burner system. All models will
be supplied with a Honeywell smart valve gas control and will
not have a variable flame control. There are two air switches
that are controlling the gas control system, and are located in
the bottom of this fireplace. These gas valves, and pressure
switches communicate with the electrical control panel via a six
conductor cable supplied with the fireplace.
To operate the fireplace, Montigo has supplied and installed
twenty feet of low voltage wire to this electrical control panel.
Connect the two wire harness to a standard single pole ON/
Off switch located at a location of your choice. You may also
extent these wires to any length, as long as you select a wire
of equal quality.
XG0774 - 171019
R320-ST & R420-ST Power Vent Indoor Gas Fireplace
Installation
Introduction to the R-Series Fireplace:
The complete system will require a firebox, a power vent module,
an electrical control panel, and a vent system. The appropriate vent
system will connect the firebox to the power vent module and will be
placed in a vertical or horizontal location. The R-Series fireplace
is not a heat efficient fireplace and should not be used with a
thermostat to heat your home. This product is a fire 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 fireplace.
Install location:
The R-Series fireplace may be installed in any location that maintains
proper clearances to air conditioning ducts, electrical wiring, and
plumbing. Safety, as well as efficiency of operation, must be considered
when selecting the fireplace location. Try to select a location that does
not interfere with room traffic, has adequate ventilation, and offers
an accessible pathway for Power Vent installation.
Basic Operation:
The gas control components of this fireplace are located in the bottom
of the firebox below the burner system. All models are supplied with
a Honeywell smart valve gas control and do NOT have a variable
flame control. There are two air switches that control the gas control
system, located in the bottom of the firebox. These gas valves and
pressure switches communicate with the electrical control panel
through a six conductor cable supplied with the fireplace.
To operate the fireplace, 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.
CAUTION: Do NOT connect power to these wires.
ON/OFF Control of this appliance can also be performed using an
optional remote control available from your Montigo dealer.
WARNING
The R320ST & R420ST are classified under power vented fireplace systems.
Under no circumstances can these models be installed without a Power Vent Module.
For Horizontal Vent Installations, use 5”/8” Power Vent Motor PVHEX58-300,
PVHFL58-300 or PVHIN58-300 with TMHIN58-40.
For Vertical Vent Installations, use 5”/8” Power Vent Motor PVVEX58-300.

Section 2: Framing
Step 1. To ensure your glass viewing area is at the optimum height,
follow the figures and examples below to determine where to build
the fireplace platform. For example: Determine the height where
you want the bottom edge of the glass to be, then subtract 14¾"
from that dimension. The result is the dimension you will build the top
of the platform to. For example if you want the Bottom of the Glass
to be at 24" the equation is 24" - 14¾" = 9¼". So that the top of the
platform will be at 9 1/4". This dimension takes in account the
height of the platform, plywood and adequate clearances.

to remember the following:
If the surround of the fireplace is to be painted to match the room decor,
heat-resistant paint must be provided . Also, decorative facing must
not extend past the fireplace opening at all, because it will interfere
with the access to retainers for removal of glass door and access to
the lower compartment.
Mantels & Surrounds
National Canadian Gas Association mantel test requirements are for
fire hazard prevention to combustible materials.
Please be aware; temperatures over the mantel will rise above normal

Mantels & Surrounds
NOTE: National Canadian Gas Association mantel test requirements
are for fire 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 fireplaces which are hot, fuel and energy efficient.
Please be aware; temperatures over the mantel will rise above normal
room temperature and walls above fireplace 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, discoloration 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 fireplace as shown in Figure 2 Sec.7.

Section 8: Removing & Installing Screen and Window
Removing the Screen:
Follow the steps below to remove, or install the R320ST* /
R420ST* fireplace screen and door.
Before beginning any screen or glass removal, make sure that the unit
has not been in operation and that it is at room temperature.
Step 2: Lift out Window from Grooves
The window is removed by first lifting upward on the glass and
then by pulling the bottom out from the groove in which it was
located (see image below).
Step 1: Prepare to Lift out Screen Assembly
Grip either end of the screen assembly and pull towards yourself.
The screen assembly is held to the unit by both friction and magnets.
Step 2: Lift out the Retaining Tabs and Screen.
The Retaining Tabs are quite long and in most cases, this task would
be better performed by two people.
Once the Retaining Tabs have come away from the Fireplace, lift the
screen away and store in a safe place. The Screen is very fragile and
can be easily torn, dented or deformed. Refer to Figure 1 Sec.9 below.
Figure 2 Sec.8 Window Removal (using glass lifting tools).

Section 9: Installing the Firestones
Optional River Rocks
The R320ST* / R420ST* is supplied with glass firestones. To install
the firestones remove the trim and door as shown in the previous
section. Follow these instructions to ensure all parts are removed or
replaced as required. Once the trim and glass door is removed, place
the firestones randomly around the burners as shown in Figures 1
Sec.9 and Figure 2 Sec. 9.
Note: DO NOT cover the burner with firestones or any other
media.
The R320ST*/R420ST* has the option of installing the cultured
rocks which mimic real stone. These may be spaced at random, or
in a visual pattern of your preference. See the Montigo web site for
photographs and ideas.

See Lighting Instructions section.
General
Cleaning
■Have the fireplace and installation inspected yearly. The
inspection must include, but is not limited to, the following:
When the fireplace is first activated, there may be some smoking and
a visible film may be left on the glass. This is a normal condition, and
is the result of burning of protective coatings on new metal.
• A visual check of the entire vent system and termination.
•An inspection of the door gaskets to ensure a proper seal.
•An inspection of the burner, vent run, and primary air
openings.
• An inspection of the gas valve, gas components, and pilot
flame. For your convenience a 1/8" manifold pressure tap
is supplied on the gas valve for a test gauge connection.
• Inspection of all optional equipment; fans, etc.
■For Natural Gas this appliance requires a minimum inlet pressure
of 5.5" W.C. and a manifold pressure of 3.5" W.C.
■For Propane Gas this appliance requires a minimum inlet
pressure of 11" W.C. and a manifold pressure of 10" W.C.
■Glass must be cleaned periodically to remove any film (which is
a normal by-product of combustion) which may be visible. Film
can easily be removed by removing the door, as shown on Page
22. Handle the door carefully, and clean it with non-abrasive,
non-ammonia based glass cleaners. One of the most effective
products is Kel-Kem.
■Silicone seals on inner door during initial firing will "off gas", leaving
a visual deposit of a white substance on combustion chamber
walls. This can easily be removed using normal household
products.
■Use a vacuum cleaner or whisk broom to keep the control
compartment, burner, and firebox free from dust and lint.
■Always keep the fireplace area clear and free of combustible
materials, as well as gasoline and other flammable vapors and
liquids.
■Do not use this appliance if any part has been under water.
Immediately call a qualified service technician to inspect the
appliance and to replace any part of the control system and any
gas control which has been under water.
