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.
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.

Installing the Stove Pipe
1. Ensure that the intended pathway for the venting is clear.Try to
position the stove midway between two studs to avoid having to
cut them. Cut and frame a 10" x 10" hole for the termination.
2. Attach the top vent conversion box (Part # FST04) to the stove's
flue collar as shown in Figure 14. Secure it with four sheet metal
screws.

3. Cut the flex pipe (Part # FST08) to length and install the second
flex collar. Install the flex liner onto the inner collar of the conver-
sion box.

The minimum vertical rise for a Top Vent Installation is 2', which al-
lows 1 - 90° elbow and a maximum horizontal run of 10'. With greater
vertical rise, the number of 90° bends may be increased according to
the chart below. The total maximum horizontal run (H
T
) is also shown,
and the run between each elbow (H
x
) may be any length, as long as it
does not exceed (H
T
).

Example:
If V= 12', the vent run may use up to 3 - 90° elbows.
If H

then H

This would be an acceptable installation.
