Vent Installation
This section covers the installation of direct venting and terminations.
Installation Requirements

H38DF-Series fireplaces are certified for use with Montigo Standard Series
(5" / 8") venting components.
 Minimum clearance to combustible construction around the vent pipe
is 1" on all sides, except on horizontal venting where the top of the pipe
must have a clearance of at least 2".
 Use only certied Montigo vent components. (Use of other parts will void
the Montigo warranty, and may impede the operation of the fireplace.)
 All joints must be secured with a minimum of two screws per joint
 Vent terminations must not be recessed in walls or siding
 Horizontalrunsmustbesupportedbyaminimumoftwo supportsperhorizontal
run. A minimum of one screw on each side of support is also required
 Flex vent sections may be stretched up to 50% of their total length (eg. a
24" section may be stretched to 36")
 Solid vent sections may be cut less than half way from the female end
 Venting components can be used in any combination of solid/rigid pipe or flex
pipe and in any orientation (Male connectors can face in any direction)
Vent Terminations
Selecting A Termination Location
Choosing your vent termination location will help to determine whether
youneedtouseatopventorrearventreplace.Figure6a,below,shows
typicalreplacelocationsandtheventingoptionstheyprovide.
For a more detailed diagram of allowed termination locations, see Ap-
pendix A.
Figure 6a. Fireplace locations and vent terminations.
Installing The Gas Line
The gas line must be installed before nishing the H38DF-Series
Fireplace. Natural Gas requires a minimum inlet gas supply pressure
of5.5"W.C.&amanifoldpressureof3.5"W.C.Propane Gas requires a
minimuminletgassupplypressureof11"W.C.&amanifoldpressureof
10"W.C.Provisionmustalsobemadefora1/8"N.P.T.pluggedtapping
and be accessible for test gauge connection immediately upstream of
thegassupplycontrolstotheappliance.Thereplacegasconnection
and the main operating gas valve is located behind the removable trim
at the bottom of the unit and need only be attached to the gas line with
anapprovedtting,asrequiredbytheapplicable installation codes.
To access the replace gas connection the main burner must be
removed as shown below in gure 5b.
•Onlyusegasshut-offvalvesapprovedforusebythestate,province,
region, or governing body, in which the appliance is being installed, or
as required by the applicable installation codes.
•Flexiblegasconnectorsmustnotexceed3feetinlength,unlessitis
allowable within applicable installation codes.
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 flame of any kind to test for leaks.
Figure 5a. Gas line access.
The appliance and its individual shut-off valve must be disconnected
from the gas supply piping system during any pressure testing of that
system at test pressures in excess of 1/2 psig (3.5 kPa).
The appliance must be isolated from the gas supply piping system by
closing its individual manual shut-off valve during any pressure testing
of the gas supply piping system at test pressures equal to or less than
1/2 psig (3.5 kPa).

Cautions:
 Vent terminations can be very hot. If the termination is less than 7 feet
above a public walkway, it should be fitted with a certified Montigo
Heat Guard. (Part no. PTKOG).
Do not obstruct, or attempt to conceal the vent termination.
These actions will affect the operation of the fireplace, and may
be hazardous.
In heavy snow areas, take extra care to prevent snow buildup
from obstructing the vent termination.
Use Montigo Vinyl Heat Shield (Part no. VSS) when using on ap-
plications with vinyl siding to guard against possible damage.

Rear Vent Venting Runs
The H38DF-Series Rear Vent has three possible installations which do
not require vertical lift, all of these installations require that you install
the RHS101 heat shield.
Heat Shield
The heat shield (RHS101) must be used on all installations straight
through the wall, at the point where the vent pipe connects to the
termination. With the heat shield, proper vent clearances can be
maintained. The heat shield is not included with the replace.
To installthe heat shield,slide one sectionover thevent pipe onthe inside
of the wall opening, with the circular portion inside the wall cavity. Screw
the shield in place over the wall opening. Install the second section on
the outside of the wall opening sliding the circular portion into the wall
opening. Refer to Figure 19.
Figure 19. RHS101 Heat Shield. Install by sliding over the vent pipe
where it passes through combustible construction.
Note: Through the wall venting kits are also available for both
the Straight and the Corner Installation. The Kit includes a heat
sheild,aPFL-12(f/f)exiblepipe,andaterminationwithorwithout
a mounting frame.
1. Straight Installation.
The height from the hearth to the center of the termination is 21
3/4".Forstraightinstallationsusea12"extensionpipe(PXT-12)
with female/female connections. For shorter installations, cut the
vent to the desired length. Refer to gure 19.
Ensure that the RHS101 heat shield is installed before attaching
the pipe to the termination.
Note: For Rear Vent models, maximum horizontal run with no
verticalliftmustneverexceed12".

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.
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

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,plasticorpictures. Thiscancausemelting,deformation,
