notinterferewithroomtrafc,hasadequateventilation,andoffersan
accessible pathway for Direct Vent installation. Refer to page 4 - Vent
Installation for more information.
Thereplacedimensionsareshownbelow:
When installing a shelf over the top of  the replace, the following
guidelines must be adhered to: For Rear Vent applications the
minimumclearancefromthetopofthereplacetoashelfis9".For
Top Vent applications, the minimum clearance is 17 1/2". (Minimum
2" clearance must still be maintained around the vent pipes.)

Vent Installation
This section covers the installation of direct venting and terminations.
Installation Requirements
■ HW38DFreplacesis certiedforusewithMontigoStandardSeries(4"/7"
TOPONLY)or(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")
■Flex vent sections over 6 feet must fall within the limits set by the venting
graphandmusthaveaminimumverticalriseof3inchesperfootofex.
■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
ex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.
Cautions:
■ Vent terminations can be very hot. If the termination is less
than7feetaboveapublicwalkway,itshouldbettedwitha
certiedMontigoHeatGuard.(Partno.MTKOG/PTKOG).
■Donotobstruct,orattempttoconceal,theventtermination.
Theseactionswillaffecttheoperationofthereplace,
and may be hazardous.
■In heavy snow areas, take extra care to prevent snow
buildup from obstructing the vent termination.
Figure 6a. Fireplace locations and vent terminations.
Installing The Gas Line
ThegaslinemustbeinstalledbeforenishingtheHW38DF 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).

Rear Vent Venting Runs
The HW38-DF 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. Heat Shield. Install by sliding over the vent pipe where it
passes through combustible construction.
1. Straight Installation.
The height from the hearth to the center of the termination is 28
3/4".Forstraightinstallationsusea18"extensionpipe(PXT-18)
with female/female connections. For shorter installations, cut the
PXT-18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18".

lowertrim)counter-clockwise.
■ Tolowertheameheight,turnclockwise.
Cleaning
Whenthereplaceisrstactivated,theremaybesomesmokingand
avisiblelmmaybeleftontheglass.Thisisanormalcondition,andis
the result of burning of protective coatings on new metal.
■ Glassmustbecleanedperiodically to remove any lm (whichis
a normal by-product of combustion) which may be visible. Film
can easily be removed by removing the door, as shown on page
15. Handle the door carefully, and clean it with non-abrasive glass
cleaners. One of the most effective products is Kel Kem.
■ Siliconesealsoninnerdoorduringinitialringwill"offgas",leaving
a visual deposit of a white substance on combustion chamber walls.
This can easily be removed using normal household products.
■Use a vacuum cleaner or whisk broom to keep the control
compartment,burner,andreboxfreefromdustandlint.
■Logs may be cleaned periodically with a vacuum to remove soot or
