(Minimum 1" clearance must still be maintained around the vent
pipes, except on horizontal venting sections where the top of the pipe
must have a clearance of 2")
For protection against freezing temperatures, it is recommended that
outer walls of the chase be insulated with a vapour barrier. This will
reducethepossibilityofacold-airconvectioncurrentonthereplace.

3).Oncecomplete,slidethereplaceintothecompletedcavity.
4). Next, tack four studs (Vertical, "broken line") in place, Figure 2c.

Installation
Installing The Gas Line
ThegaslinemustbeinstalledbeforenishingtheH(L)38DF-ST 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.
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).

Installing The Remote Switch
The H(L)38DF-ST are equipped with a remote-operated valve for use
with a wall switch. See Figure 21 for information on wiring the switch.
The valve is pre-wired and generates its own power. DO NOT con-
nect any external power to it.
Note: Theswitchlocationmustnotexceed30'fromthereplace.
Vent Installation
This section covers the installation of direct venting and terminations.
Installation Requirements
 H(L)38DF-ST Seriesreplacesarecertied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replace.)
 All joints must be secured with a minimum of two screws per joint
 Vent terminations must not be recessed in walls or siding
 Horizontal runs must be supported by a minimum of two supports per hori-
zontal 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")
Venting components can be used in any combination of solid/rigid
Solid vent sections may be cut less than half way from the
tapered end
 Venting components can be used in any combination of solid/rigid pipe or
expipeandinanyorientation(Maleconnectorscanfaceinanydirection).

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
applications with vinyl siding to guard against possible damage.
CAUTION:
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

Top Vent Venting Requirements
Before you install any venting, you must determine whether the
venting run will be acceptable. Unacceptable venting can affect the
replace'scombustion.
for installations with horizontal venting runs of 0-16 feet, use the
vent graph, as described below
the maximum horizontal vent run is 16 feet.
