Section 3-2: INSTALLING A ROOF MOUNTED DIRECT VENT
TERMINATION (PVTK-1)
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, (asphault 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 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 Waterproong Consultant
for further recommendations.

for further recommendations.
Installation
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.
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.

The RHS8 Heat shield CANNOT be used WITHIN 36" horizontal or
46" vertically of the replace, (see gure 19a). For applications within
these dimensions the RHS101 Heat Shield MUST be used. .
To install the RHS8, frame an opening in combustible construction,
Figure 19 below. Slide the Heat shield in place over the vent pipe
which attaches to the replace. After the replace and vent pipe has
been installed, clearances should match the dimensions in Figure 19.
Installing a Wall Mounted RHS101 Heat shield.
The RHS101 Heat shield MUST be used where the RHS8 Termination
(Figure 19 and 19a) CANNOT be used. Use the RHS101 within 36"
horizontal or 46" vertical.
To install the RHS101, Slide the Inner Section over the vent pipe that will
connect to the replace. Fasten the vent pipe to the back of the replace
with a Min. of three sheet metal screws.
(Note: ensure you DO NOT EXCEED the Max. 12" replace clearance).
Next, slide the RHS101 outer section from the outside of the structure,
see Figure 19c.
To complete the installation fasten the Heat Shield Outer Section &
Termination frame to the structure Figure 19d.

Section 5: Installing the Gas line
Installation
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 to purchase a conversion kit.
Conversion kits must be installed by a qualied service technician.
Section 5-2: GAS PRESSURE
Optimum appliance performance requires proper input 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.
Note: 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 leak is detected until
bubbling stops completely or leak is no longer detected.
DO NOT use a ame of any kind to test for leaks.
WARNING!
When pressure testing the replace, Gas line, and input system
follow the appropriate local codes or your area. DO NOT
connect the replace to pressures in excess of 1/2lb. This will
damage the gas control valve.
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 22 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.

Section 6: Finishing
Installation
WARNING!
Do not attempt to clean glass when hot.
Do not clean glass with abrasive materials as any glass etch-
ing may cause premature glass failure.
WARNING!
We recommend careful consideration be given to the effects of
elevated mantel temperatures which may be in excess of product
design, for example: candles, plastic or pictures. This can cause
melting, deformation, discoloration or premature failure of T.V.
radio, and other electronic components.
DO NOT OPERATE THIS FIREPLACE WITHOUT THE GLASS
DOOR OR WITH A BROKEN GLASS DOOR.
CAUTION!
Figure 24. Combustible mantels and facings.
WARNING!
When covering the upper metal portion of the replace, up to 4"
(as shown, Fig.24) with a non-combustible material Please Note:
The decorative facing materials may be subject to temperatures
in excess of 250° F. This should be considered when selecting
facing materials.
Finishing Around the Fireplace
Combustible mantels and mouldings may be safely installed over the
top and on the front of the replace provided that they do not project
beyond shaded area shown in Figure 24.
Fireplace Facing
When sizing the nish material for your replace, it is important to remem-
ber the following: THE OPENING MUST NOT BE OBSTRUCTED IN ANY
WAY - to do so restricts the air supply for the control compartments
and heat exchanger it also prevents access for servicing controls.
The face of the replace may be painted to match the room decor,
provided you use a heat-resistant paint. Decorative facing must not
extend past the replace opening at all, because it will interfere with
the access to retainers for removal of glass door.
Mantels & Surrounds
NOTE: National Canadian Gas Association mantel test requirements
are for re hazard prevention to combustible materials.
New technology, to meet consumer and government demands for the
wise use of energy, has prompted us to manufacture many models of
replaces which are hot, fuel and energy efcient.
Please be aware; temperatures over the mantel will rise above normal
room temperature and walls above replace may be hot to touch.
Warning:
When covering the upper metal portion of the replace with a non-
combustible material Please Note: The decorative facing materials
may be subject to temperatures in excess of 250° F. This should be
considered when selecting facing materials.
We recommend careful consideration be given to the effects of elevated
mantel temperatures which may be in excess of product design, for
example: candles, plastic or pictures. This can cause melting, deformation,
discoloration or premature failure of T.V. and radio components.
Painting:
Special care is recommended by the Master Painters and Decorators
Association, when painting the replace surrounds, to select and apply
a quality Alkyd sealer prior to the applying of latex paints. This is to
prevent leaching of water from evaporation and causing a brownish
staining effect to paint over coats.
