Installing The Gas Line
The gas line must be installed before completing the installation.
Natural Gas requires a minimum inlet gas supply pressure of 5.5"
W.C. & a manifold pressure of 3.5" W.C. Propane Gas requires a
minimum inlet gas supply pressure of 11" W.C. & a manifold pressure
of 10" W.C. Provision must also be made for a 1/8" N.P.T. plugged
tapping and be accessible for test gauge connection immediately
upstream of the gas supply controls to the appliance. The stove is
supplied with a flexible gas connector which is factory installed. The
gas valve is located behind the pedestal base, and is accessible from
the back or by removing the control panel cover plate. It should be
attached to the gas line with an approved fitting, as required by the
applicable installation codes.
• Only use gas shut-off valves approved for use by the state, province,
region, or governing body, in which the appliance is being installed, or
as required by the applicable installation codes.
• Flexible gas connectors must not exceed 3 feet in length, unless it is
allowable within applicable installation codes.

Direct Vent Installation
This section covers the installation of venting and terminations.
Installation Requirements
 Rio Stoves are certified for use with Montigo Standard Series (4"
/ 7") venting components and approved Vent Kits (listed below)
 Minimum 1" clearance to combustibles required for vent pipes
 Use only certified Montigo vent components. (Use of other parts
will void the Montigo warranty, and may impede the operation of
the stove.)
 All joints must be secured with a minimum of two screws per joint
 Vent terminations must not be recessed in walls or siding
 Horizontal runs must be supported by a minimum of two supports
per horizontal run. A minimum of one screw on each side of support is also required
 Flex vent sections may be stretched up to 50% of their total length
(eg. a 24" section may be stretched to 36")
 Maximum horizontal run for a flex section with no vertical rise is 3
feet.
 Flex vent sections over 3 feet must fall within the limits set by the
venting graph and must have a minimum vertical rise of 3 inches
per foot of flex.
 Venting components can be used in any combination of solid/rigid
 Solid vent sections may be cut less than half way from the tapered
end
 Venting components can be used in any combination of solid/rigid
pipe or flex pipe and in any orientation (Male connectors can face

Figure 4. Gas line access.
During any pressure testing of the gas supply piping that excedes 1/2
psig (3.5 kPa), the appliance and its individual shutoff valve must be
disconnected from gas supply system.
Vent Terminations
Selecting A Termination Location
Choosing your vent termination location will help to determine whether
When pressure testing the gas supply piping system at test pressures
of less than or equal to 1/2 psig (3.5 kPa), the appliance must be
isolated from the gas supply piping system by closing its individual
manual shutoff valve.
Note: After gas line is connected, each appliance connection,
valve and valve train must be checked while under normal
operating pressure with either a liquid solution, or leak
detection device, to locate any source of leak. Tighten
any areas where bubbling appears or leak is detected until
bubbling stops completely or leak is no longer detected.
DO NOT use a flame of any kind to test for leaks.
Figure 5. Fireplace locations and vent terminations.
Cautions:
 Vent terminations can be very hot. If the termination is less
than 7 feet above a public walkway, it should be fitted with a
certified Montigo Heat Guard. (Part no. MTKOG)
 Do not obstruct, or attempt to conceal, the vent termination.
These actions will affect the operation of the fireplace, and may
be hazardous.
 In heavy snow areas, take extra care to prevent snow buildup
from obstructing the vent termination.

Installation.
1. Mark an 11" x 11" hole centred exactly 25" from the centre of the
stove's flue collar to the hearth (- the surface the stove will be sitting directly on). This hole will be cut right through to the exterior
of the building for the vent pipe to pass through. Precise location
of this hole is very important: check your measurements before
cutting!
2. Connect the FST11 to the back of the stove, but do not fasten it.
Slide the cover plate and the inner wall plate onto the FST11, with
their open edges down.
MTKOG
1. Ensure that the two long mounting brackets are facing the bottom of the termination. (See inset). This will provide more heat
protection at the top of the termination, where temperatures are
highest.
Place the stove on its hearth, and slide it back until the FST11
pipe protrudes through the hole in the wall and the stove is in the
desired position. (See figure 7).
2. Attach to the faceplate of the termination using four sheet metal
screws.
Rear Vent Venting Runs
The Rio Pedestal Stove may be vented directly out the back through
an exterior wall. This application allows the stove to be installed with
no visible venting in the room. You must use the Direct Vent - Rear
Vent Kit (Part # FSTK01) for this installation.
Rear Vent Installation Requirements.
 The height from the hearth to the center of the vent pipe is 25".
 The maximum horizontal run for a Rear Vent installation is 14".
 The FST-11 (18" length section is supplied for connecting the
stove to the termination. The FST-11 may be cut to required
length, and must not exceed 14".
 The two wall plates and the cover plate included with this kit must
be installed for proper operation.

Slide the inner wall plate back against the wall. Level the plate,
making sure it completely covers the opening in the wall, and fasten it in place using four wood screws. (Note that the heat shield
connected to the plate is not concentric -- its top edge should sit
close to the inside top edge of the 11" x 11" hole.) Snorkel
Slide the Cover Plate onto the inner wall plate and fasten it with
one black sheet metal screw on each side.
3. The (outer) wall plate is used to mount the snorkel-type termination to the building exterior. Position the wall plate over the 11 " x
11" hole.
Push the heat shield portion into the opening so that it mates with
the heat shield on the inner wall plate. This will properly position
the wall plate over the opening. (Refer to figure 8).
Level the wall plate. It may be installed either over top of the
exterior cladding (brick, stucco, siding, etc.), or against the
exterior sheathing. If installing it directly on the exterior sheathing,
you must cut away the siding or other fascia by tracing an outline
around the wall plate.
4. Slide the stove forward and remove the FST11 pipe. Attach the
FST11 to the snorkel termination, and mount the assembly on
the outer wall plate between the two alignment tabs as shown in
figure 9. Fasten it in place with at least two screws at the top and
two at the bottom.

Top Vent Venting Runs
For the Rio Pedestal Stove there are two types of Top Vent (DV)
installations: A) Horizontal (Through-The-Wall) Installations and B)
Vertical (Through-The-Roof) Installations.
Allowable Vent Runs
Before you install any venting, you must determine whether the
venting run will be acceptable. Unacceptable venting can affect the
fireplace's combustion. Figure 12 shows various vent rises and the
corresponding number of 90° bends which can be made.
H1
H2
A) Through-the-Wall (Horizontal) Venting Option
The horizontal venting option requires an FSTK02 Vent Kit. Figure 13
shows the components which are used to attain different vent heights.
Additional stove pipe or Montigo Standard Series vent components may be used to increase the vent run, as long as the run still falls
within the limits set out in Figure 12.

4. Install the first stove pipe onto the conversion box by sliding it over
the flex pipe (refer to Figure 14). Install a spacer spring around the
flex liner. Secure the pipe with at least two ½" hex screws spaced approx. 3/4" from the joint. Slide the remaining vertical stove pipes
into place, without fastening them. Install a spacer spring inside
each stove pipe section.
5. Cut the horizontal stove pipe (FST11) to length. Slide it and the
90°elbow over the flex and onto the vertical pieces of stove pipe.
Install the last spacer spring inside the horizontal section. Slide
the Decorative Wall Plate (Part # FST07) onto the horizontal section, making sure the unpainted side faces the wall.
When venting through the roof, use an FSTK04 Vent Kit. Additional
stove pipe or Montigo Standard Series vent components may be
used to increase the vent run, as long as the run still falls within the
limits set out in Figure 16.
Vertical Vent Requirements:
Vertical terminations (Part # MVTK-1) must be installed:
•
minimum 2' above the highest point where the vent passes
through the roof
•
minimum 6' from a mechanical air inlet
•
minimum 18" from a parapet wall
Completing the Vent Run
Maximum vent height is 25 above the stove's flue collar.
6. Slide the stove back into position so the pipe protrudes through
the wall. Pull the flex forward and attach it to the termination (or
other vent sections, if necessary, to extend the vent run) with high
temp sealant. Run a bead of high temp sealant around the stove
pipe and push the termination on. Attach the MTO-3 termination to
the wall as shown on page 5.
(Note: Flame characteristics may change if the maximum vent height
is used.)
Adjust the position of the stove pipes so thethat joints are all
equally spaced. Ensure that there is at least 1 1/2" overlap between each section.
Secure each stove pipe joint with at least three ½" hex screws
spaced approx. 3/4" from the joint (so that the brass ring will
cover both the joint and the screws).
A maximum of two offsets (each offset has two 90° bends) may be
made. The total length of the offset(s) must not be more than 25% of
the vertical vent height, when measured from center to center of the
piping.
Example: Vertical vent height - 20 feet
25% of 20' = 5' max. offset allowed
2 - 2' offsets required = 4' offset
This vent configuration is acceptable.
Finishing
7. Now slide the Decorative Wall Plate against the hole, level it, and
secure using four screws.
8. Cover each joint in the stove pipes with a brass decorator ring.
The rings should cover the joint as well as the sheet metal screws.

Adjusting the Burner
Raising or lowering the Flame Height
Rio Stoves are equipped with an adjustable burner, allowing you to
raise or lower the flames. To adjust the flames, locate the black knob
marked 'Flame Control', in the centre of thecontrol panel (See Figure
31).
 To raise the flame height, turn the black knob marked 'Flame
Control' counterclockwise.
 To lower the flame height, turn clockwise.

Maintenance
CAUTIONS
 Fireplace gas control must be in the “OFF” position and pilot
and main burners extinguished when cleaning appliance with
a vacuum.
 Doors and logs can get very hot. Handle only when cool.
General
 Have the fireplace installation inspected yearly, including a visual
check of the vent system, the burner and the pilot flame. For your
convenience a 1/8" manifold pressure tap is supplied on the gas
valve for a test gauge connection. See Figure 28.  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.
 Always keep the fireplace area clear and free of combustible
materials, as well as gasoline and other flammable vapours 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.
Figure 31. Hi-Lo' Adjustment on the Rio Stove's gas valve.
Cleaning
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.
 Glass must be cleaned periodically to remove any film (which is a
normal biproduct of combustion) which may be visible. Film can
easily be removed by removing the door, as shown on page 11. Handle the door carefully, and clean it with non-abrasive 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.  Logs may be cleaned periodically with a vacuum to remove soot
WARNING:
Do not attempt to clean glass when hot.
Do not clean glass with abrasive materials as any glass etching may cause premature glass failure.
