When installing a shelf over the top of the replaces, the following
guidelines must be adhered to:
For Rear Vent applications, the minimum clearance is 2" from the rear
of the replace to a wall, or any combustible materials, and 9" clearance
from the top of the replace to the underside of any combustible shelf
materials.
For Top Vent applications, the minimum clearance is 2" from the rear of
the replace to a wall, or any combustible materials, and 17 1/2" to the
underside of any combustible shelf materials.
(Minimum 2" clearance must still be maintained around the vent
pipes.)

Section 3: Venting
Montigo supplies a variety of direct venting and termination options.
The direct vent termination location MUST be selected such that
it is the highest point in the venting assembly. It should also be
selected such that it provides the shortest vent run possible. Should it
be impossible to ensure that the termination is the highest point or to
meet the venting guidelines laid out below please contact your Montigo
dealer to discuss power venting options.
NOTES FOR PLANNING VENTING:
Venting can originate from the unit through the top or through the rear
Venting can terminate through the roof or through an exterior wall.
Refer to Appendix A - Termination Locations to ensure the planned
termination location is acceptable.
Once the termination location has been established, refer to the
appropriate section below for installation details
All replaces shipped from the factory are Top vent.
See Section 3-1 for converting the unit from top vent to rear vent.

Use the following instructions to convert an L38DF* for Rear Vent use:
1. Remove the Rear ue cover and gasket (5" and 8") on the ue
outlet, as shown in Figure 7.
2. Next, Remove the Top ue collar's (5" and 8") on the ue outlet,
as shown in Figure 7.
3. Install the (removed) Rear ue cover and gasket material, to the
Top vent outlet. Fasten the cover with included hardware, as

Section 3-2: INSTALLING A ROOF MOUNTED
DIRECT VENT TERMINATION (PVTK-1)
This section applies to installations where the direct vent termination will be roof mounted.
Section 3-2-1: VENTING LAYOUT
Selection of components and details of venting lay out should
adhere to the following guidelines:
The maximum termination point is 32’ above the replace (NOTE:
if the maximum termination height is used, the ame pattern
may be affected).
The Vertical termination must be a minimum 2’ higher than where
the termination exits the roong materials, (asphalt shingles,
cedar shakes, etc). This distance should be measured from the
high side of the roof slope where the ue ashing intersects the
roong materials. (see Figures 11 to 11c *).
Termination location must be a minimum 6’ from a mechanical
air inlet.
Termination location must be a minimum 18” from a parapet wall.
A maximum of two offsets (each offset is made up of 2-90°
bends) may be made.
Install a restop at any location where venting passes through
combustible materials and construction.
Utilize support straps, or support plates, and rings (as required)
to meet acceptable building practices.
Install all roof ashing and storm collars as shown.

Section 3-2-2: VENTING COMPONENTS
Select from the following components and associated Montigo part
numbers for installation of a Roof Mounted Termination. Use only
Montigo Vent Components. Use of non-Montigo parts will void the
warranty and may impede operation of the replace.
Connection and installation of the vent components should adhere to
the following guidelines:
Use any combination of rigid and Flex pipe as required.
Flex sections may be stretched up to 50% of their total length
(e.g. a 24” section maybe stretched to 36”).
Connect all vent sections using a minimum of three sheet
metal screws on the outer pipe ue.
Ensure the pipe ends male to female slide in a minimum of
1 1/2” of overlap.
Ensure all runs are supported with a minimum of 3 supports
per 10’ of venting.
When hanging/ supporting venting, ensure that 1” clearance
is maintained on sides and bottom of vent runs and 2” above
horizontal vent runs to any combustible material.
Ensure when cutting sections of rigid pipe to maintain integrity
of internal supports.
Place the springs, supplied with the pipe kit, between the
outer and inner pipes to keep the pipes separate and avoid
any possible hot spots.
Montigo recommends the use of a ex section for the nal pipe
connected directly to the replace offering greater exibility of
installation and absorption of movement.
When penetrating a combustible ceiling, a ceiling restop
must be used.
Montigo recommends that all exterior corners and joints be
sealed with exterior caulking however we encourage you to
consult your Building Envelope Engineer or Waterproong
Consultant for further recommendations.
