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 1" from the rear of
the replace to a wall, or any combustible materials, and 13" clearance
from the top of the replace to the underside of any combustible shelf
materials.
For Top Vent applications, the minimum clearance is 1" 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.
1” clearance is maintained on sides and bottom of vent runs and 2”
above horizontal vent runs to any combustible material.
Installing The Standoffs
To avoid elevated mantel temperatures, all H*38C* gas replaces
are required to have the supplied standoffs installed. The replace is
supplied with two standoffs. Bend and install these standoffs on top
of the replace as shown in Figure 6, ensuring that the height of the
standoff maintains a 4" clearance from the top of the unit to the 1st
combustible stud.
Nailing Flange Extension
The 4" nailing ange extension is shipped attached to the top edge of
the replace, see Figure 1.
The nailing ange extension may be substituted with a piece of NON-
Combustible material of the same thermal characteristics, ie: cement
board or equivalent to t the opening. This is recommended in applications
where the facing materials will not adhere to the metal nailing ange.
To remove the Nailing Flange Extension follow the directions below:
Figure 6� Installing the H*38C* standoffs.
† Note: Clearance from top of replace to a ceiling within the replace
enclosure.
** Note: For mantel clearance, please refer to Section 6: Finishing
on page 21.

Section: 3 The Direct Vent System
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 originates 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.
Silicone application is NOT required when joining Montigo
vent pipes and components�
Section 3-1: Converting to Top Vent / Rear Vent
Use the following instructions to convert an H*38C* for Rear Vent use:
1. Remove the Rear ue cover and gasket (5" and 8") on the ue
outlet, as shown in Figure 8�
2. Next, Remove the Top ue collar's (5" and 8") on the ue outlet,
as shown in Figure 8�
3. Install the (removed) Rear ue cover and gasket material, to the
Top vent outlet. Fasten the cover with included hardware, as
illustrated Figure 8a.
4. Install the (5" and 8") collars to the rear vent outlet using the
included hardware, as illustrated Figure 8a.

This section applies to installations where the direct vent termi-
nation 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 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. (see Figures 9 to 9c).
Termination location must be a minimum 6’ from a mechanical
air inlet.
Termination location must be a minimum 18” from a parapet wall.
For a more detailed diagram of allowed termination locations,
see Appendix A.
A maximum of two offsets (each offset 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.

Section 3-3-1: Venting Layout
Selectionofcomponentsanddetailsofventing layout should adhere
to the following guidelines:
Vent terminations must not be recessed in walls or siding.
For Heat Shield requirements see page 16.
Once the proposed venting layout has been determined refer to
eitherFigure12,12a,14, or 14atoensurethelayoutis acceptable.
Wall Mounted Terminations: TOP VENT
Alldimension lengths for vertical or horizontal runsaremeasured
from center of the vent pipe.
Venting runs must fall within the limits set by the venting graphs,
see Figure 12 or 12a.
The Venting Graph
Measure the vertical height from the replace hearth to the centre of
the termination and the horizontal run from the replace ue collar to
the wall ange of the termination. Plot on the Venting Graph Figure 12
or 12a with an 'X'.
If the 'X' falls on or above the top boundary of the shaded area, the
installation is acceptable.
Example A: (Acceptable Installation)
If the vertical dimension from the hearth is 126" and the horizontal
run to the wall ange of the vent termination is 138", this would be
an acceptable installation.
Example B: (Unacceptable Installation)
If the vertical dimension from the hearth is 36" and the horizontal
run to the wall ange of the vent termination is 84", this would
NOT be an acceptable installation�
Example C: (Unacceptable Installation)
If the vertical dimension from the oor of the replace is 60" and
the horizontal run to the wall ange of the vent termination is 144",
this would NOT be an acceptable installation�

Connection and installation of the vent components should
adhere to the following guidelines:
Section 3-3-2: Venting Components
The following components and associated Montigo part num-
bers are available for installation of a Wall Mounted Termination�
Use only Montigo Vent Components� Use of non-Montigo parts
will void the warranty and may impede operation of the replace.
IMPORTANT:
Please Refer to your Building Envelope Engineer
or Waterproong Consultant for a review of ALL
penetrations through exterior walls or the roof�
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.
Firestops must be installed as required by National & local codes.
Montigorecommendsthatallexteriorcornersandjointsbesealed
with exterior caulking. However, we encourage you to consult
your Building Envelope Engineer or Waterproong Consultant
for further recommendations.
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.
Rigidpipemaybecutlessthanhalfwayfrom the female end only�
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.

Section 5-1: Fuel Conversion
Verify that your replace is compatible with your available gas
type. (Natural Gas or Propane shown by "N" or "L" in your
model number
If gas type is not compatible, contact your local Montigo
representative.
Conversion kits must be installed by a qualied service technician.
Section 5-2: Gas Pressure
Optimumapplianceperformancerequiresproperinput pressures.
Gas line sizing requirements will be determined in ANSI Z221.3
National Fuel Gas Code in the USA and CAN/CGA B149 in
Canada.
Pressure requirements are:
Gas Pressure Natural Gas Propane
Minimum inlet pressure 5�5in� w�c� 11in� w�c�
Manifold pressure 3�5in� w�c� 10in� w�c�
The manifold outlet pressure is set from the factory to the
appropriate pressure but should be veried.
To check pressures, control valves have a provision to remove
a 1/8” N.PT. plug to be tted with a hose barb.
Montigo requires a service shut off valve be located in an
accessible location to isolate the gas supply.
Only install gas shut-off valves approved for use by the state,
province, or other governing body in which the replace is being
installed.
Section 5-3: Gas Connection
See Figure 21 below for location of gas line access.
Flexible gas connectors must not exceed 3 feet in length, unless
allowable within local regulations.
Connect incoming gas line to the 1/2"or 3/8" gas inlet port.
Purge all air out of gas line.
Check appliance connection, valve and valve train under normal
operating pressure with a commercially available leak check
solution.
DO NOT USE A FLAME OF ANY KIND TO TEST FOR LEAKS�
After gas line is connected, each appliance connection, valve and valve train MUST
be checked while under normal operating pressure with either a Liquid Solution, or
Leak Detection Device, to locate any source of leak. Tighten any areas where
bubbling appears or a 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. A fire or explosion
will occur, causing serious injusy, property damage or death.
DANGER
When pressure testing the fireplace, Gas line, and input system follow the appropriate
local codes or your area. DO NOT connect the fireplace to pressures in excess of
1/2lb. This will damage the gas control valve.
NOTICE
WARNING
When installing the replace - gas lines, ttings,
accessories or any other objects cannot impede the
proper movement of the door buckles.
