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 sup-
port 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
in any direction)
Vent Terminations
Selecting A Termination Location
Choosing your vent termination location will help to determine whether
Installing The Gas Line
The gas line must be installed before completing the installation. Nat-
ural 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 on the back of the stove as indicated in figure 4. It should be
attached to the gas line with an approved fitting, as required by the
applicable installation codes.
• Only use gas shut-o 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.
Installation
Figure 5. Fireplace locations and vent terminations.
Note: After gas line is connected, each appliance connection,
valveandvalvetrainmustbecheckedwhileundernormal
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.
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.
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.
Figure 4. Gas line access.
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
certied 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 Direct Vent
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 8 shows various vent rises and the
corresponding number of 90° bends which can be made.
Figure 8. Venting limitations for top vent installations.
The minimum vertical rise for a Top Vent Installation is 29 1/2", which
allows 1 - 90° elbow and a maximum horizontal run of 10'. With
greater vertical rise, the number of 90° bends may be increased ac-
cording to the chart below. The total maximum horizontal run (HT) is
also shown, and the run between each elbow (Hx) may be any length,
as long as it does not exceed (HT).
Vent Rise1Max. # Max. Horiz.
(V) of elbows Run (HT)
29 1/2" (min.) 1 10'
4' 2 10'
5' 2 10'
10' 3 10'
15' 3 10'
20' 3 10'
25' (max.) See vertical vent section
1 Vertical rise is measured from the center of the stove's flue
collar to the center of the termination.
2See 'Through-the-Roof Installations'
Example:
If V= 12', the vent run may use up to 3 - 90° elbows.
If H1= 3', H2=2', and H3=3',
then HT=8'.
This would be an acceptable installation.
1. Ensure that the two long mounting brackets are facing the bot-
tom of the termination. (See inset). This will provide more heat
protection at the top of the termination, where temperatures are
highest.
2. Attach to the faceplate of the termination using four sheet metal
screws.

3. Install the first stove pipe onto the FST12 / FST14 ellipse sec-
tion (refer to Figure 9). 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.
4. Cut the horizontal stove pipe (FST11) to length. Slide it and the
90°elbow and onto the vertical pieces of stove pipe. Slide the
Decorative Wall Plate (Part # FST07) onto the horizontal section,
making sure the unpainted side faces the wall.
Completing the Vent Run
5. 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 termination to the
wall as shown on page 5.
Adjust the position of the stove pipes so thethat joints are all
equally spaced. Ensure that there is at least 1 1/2" overlap be-
tween 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).
Finishing
6. Now slide the Decorative Wall Plate against the hole, level it, and
secure using four screws.
7. 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.
Attach the ring using the black 3/8" screws provided. Make sure
the screw is facing the back of the stove. See Figure 11.
Installation Direct Vent
A) Through-the-Wall (Horizontal) Venting Option
The horizontal venting option requires an FSTK05 Vent Kit. Figure 9
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 8.

Figure 12. Vertical installation options. Left: straight vertical installa-
tion (no offsets).
B) Vertical (Through-The-Roof) Venting Option
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 12.
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
Maximum vent height is 25 above the stove's flue collar.
(Note: Flame characteristics may change if the maximum vent height
is used.)
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.
Installing the Stove Pipe
Ensure that the intended pathway for the venting is clear.Try to
position the stove midway between two joists to avoid having to cut
them. Determine the ceiling box location. Measure a minimum of 6
1/4" between the centre of the pathway and the back wall as shown
in figure 13a. For corner installations, measure 24 1/4" between the
back corner and the intended pathway as shown in figure 13b. This
will maintain the stove's minimum clear-
ances as shown on page 3. Cut and
frame an 11" x 11" hole in the ceiling and
roof as required.
Install the ceiling box as shown in Figure
13c. Ensure that there is at least 2"
clearance from the bottom of the box
to the ceiling. Fasten in place with 2
screws per side.
Slide the MEXT-2 down into position so
the male end protrudes into the room
below the ceiling box as shown in Fig-
ure 13c and secure it temporarily with an
MSPXT-7 support plate and ring.
Measure the flex pipe (FST08) and cut it
to the required length. Install the second
collar onto the end of the flex. Attach
one end of the flex to the inner collar
of the MEXT-2, and secure it with three
screws.
Slide the decorative ceiling plate about
two inches down from the end of the
top section of stove pipe. Install the top
stove pipe onto the outer collar of the MEXT-2. Now slide the decora-
tive ceiling plate up against the bottom of the ceiling box and secure it
with four screws. Install the first spacer spring by sliding it up over the
bottom of the stove pipe.
Now slide the slip section (Part # FST05) up over the flex, overlap-
ping the top section at least half its length to keep the pipe out of your
Figure 13b. Determine the ceiling box location for a corner instal-
lation. To ensure that a 10 1/2" clearance is maintaned
the centre of the flue should be 24 1/4" from the back
corner.

Operation
Lighting Instructions
See pages 12 and 13.
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
8. Handle the door carefully, and clean it with non-abrasive glass
cleaners. One of the most eective products is Kel Kem.
Silicone seals on inner door during initial firing will "off gas", leav-
ing a visual deposit of a white substance on combustion cham-
ber walls. This can easily be removed using normal household
products.
Use a vacuum cleaner or whisk broom to keep the control com-
partment, burner, and firebox free from dust and lint.
Logs may be cleaned periodically with a vacuum to remove soot
Adjusting the Burner
DX Cast Stoves are equipped with an adjustable burner, allowing you
to increase or decrease the amount of flames and heat output. To
adjust the flames, locate the black knob marked 'Hi-Lo', on the right
side of the gas control valve (See Figure 27).
To raise the flame height, turn the black knob (located behind the
lower trim) clockwise.
To lower the flame height, turn counterclockwise.
