Installation
Section 1: Installation Overview and Product Dimensions
Please review the Installation Checklist on Page 4 for general information on preparing for a successful installation of your replace.
The L52DF-ST* replace may be installed in any location that maintains proper clearances to air conditioning ducts, electrical wiring and plumbing. Safety, as well as efciency of operation, should be considered when selecting the replace location. Try to select a location that does not
interfere with room trafc, has adequate ventilation and offers an accessible path for Direct Vent installation.

Clearances
These clearances apply to all dimensions except the framed opening,
where the clearance to combustibles is 0". The L52DF-ST clearance to
unprotected combustible walls which are perpendicular to the replace
opening, must not project beyond the shaded area shown in Fig. 24.
For protection against freezing temperatures, it is recommended that
outer walls of the chase be insulated with a vapor barrier. This will reduce
the possibility of a cold-air convection current on the replace.

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
should it be impossible to meet the venting guidelines laid out below
please contact your Montigo dealer to discuss power venting options.
NOTES FOR PLANNING VENTING:
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.
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.
Roof mounted Terminations
The following details are some possible congurations for Roof
mounted terminations. See below.
PVTK1 Termination
Figure 11. Top vent, Roof mounted termination with no offset in
vent run.
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, (asphault 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.
