Figure 4. Combustible Wall Clearances
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. A clearance
to combustibles of 9" for H34DF* and a clearance to combustibles of
11" for HLB34DF* , & HLB34DF-2 is required 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 17½" to
the underside of any combustible shelf materials, Figure 4.
For Top or Rear Vent applications where the Minimum mantel height
is required above the replace, (for an alcove or low prole shelf), ALL
Materials MUST BE NON-COMBUSTIBLE. The minimum clearance is 2"
from the rear of the replace to a wall, or any combustible materials.
1” clearance is maintained on sides and bottom of vent runs and 2”
above horizontal vent runs to any combustible material.
To avoid elevated mantel temperatures, all H34 gas replaces are
required to have the supplied standos installed. The replace is
supplied with two standos. Bend and install these standos on top
of the replace ensuring that the height of the stando maintains a
6" clearance.

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:
• Ventingcanoriginate from the unit through the topor 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.
• Silicone application is NOT required when joining Montigo vent
pipes and components.
Section3-1:ConvertingtoRearVent
Use the following instructions to convert a unit for Rear Vent use:
• Remove the Rear ue cover and gasket (4" and 7") on the ue outlet,
as shown
• Next, Remove the Top ue collar's (4" and 7") on the ue outlet, as
shown
• Install the (removed) Rear ue cover and gasket material, to the Top
vent outlet. Fasten the cover with included hardware, as illustrated
• Install the (4" and 7") collars to the rear vent outlet using the included

Roof mounted terminations
The following details are some possible congurations for roof mounted
terminations. See below.
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 aected).
• The Vertical termination must be a minimum 2’ higher than where
the termination exits the roong 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 roong materials.
• Terminationlocationmustbeaminimum6’fromamechanicalairinlet.
• For a more detailed diagram of allowed termination locations, see
Appendix A.
• A maximum of two osets (each oset is made up of 2-90° bends)
may be made for vertical vent runs.
• Firestops must be installed as required by National & local codes.
• Ensure all horizontal runs are supported with a minimum of 3
supports per 10’ of venting.
• Install all roof ashing and storm collars as shown.

components should adhere to the following
guidelines:
Section 3-3-2: Venting Components
The following components andassociated Montigo part numbers are for
installation of a roof or wall mounted termination. Use of non-Montigo
approved parts will VOID the warranty and may impede operation of
the replace. • Use any combination of rigid and ex pipe as required and in any
orientation (Male connectors can face in any direction).
• 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 horizontal 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.
• Rigid pipe may be cut less than half way from the Female end only.
• Flex pipe cannot be cut
• Ensure when cutting sections of rigid pipe to maintain integrity of
internal supports.
• For ex venting, 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 oering greater exibility of
installation and absorption of movement.
• Firestops must be installed as required by National & local codes.
IMPORTANT:
Please refer to your Building Envelope Engineer
or Waterproong Consultant for a review of ALL
penetrations through exterior walls or the roof.
