Termination clearance for buildings with combustible and noncombustible exteriors.
Vertical Sidewall Installations
Important! Minimum clearance between vent pipes and combustible
materials is 3 inch on top, and 1 inch (on bottom and sides).
Important! When vent termination exits through foundation less
than20inches below siding outcrop, the vent pipe must extend
outwardsothatthehorizontalventterminationislocatedushto,
or beyond the outcrop siding.
Information on Various Venting Routes and Components
Important:Itisalwaysbesttolocatethereplaceinsuchaway
that minimizes the number of offsets and horizontal vent length.
Since it is very important that the venting system maintain its balance
betweenthecombustionairintakeandtheuegasexhaust,certain
limitations as to vent congurations apply and must be strictly
adhered to.
Figure 6
TERMINATION CLEARANCES
The graph showing the relationship between vertical and horizontal
side wall venting will help to determine the various vent lengths
allowable.
The horizontal vent run refers to the total length of vent pipe from
theuecollarofthereplacetothefaceoftheouterwall.
Venting termination shall not be recessed into wall or siding.

NOTE: Since some municipalities have additional local codes, it
is always best to consult your local authority and installation code.
The use of the following gas connectors is recommended:
— ANSI Z21.24Appliance Connectors of Corrugated Metal Tubing
and Fittings.
— ANSI Z21.45 Assembled Flexible Appliance Connectors of
Other Than All-Metal Construction
The above connectors may be used if acceptable by the authority

NOTE: Island and room divider installation is possible as long as
thehorizontalportionoftheventsystemdoesnotexceed20feet
with a minimum vertical run of 8 feet (measured from bottom of
appliance). See details in Venting Section.
NOTE: When installing this appliance against exterior wall, insulate
to applicable insulation codes.
LOCATING FIREPLACE
When you install your Direct Vent Fireplace in room divider or Flat
on wall corner positions, a minimum of 6 inches clearance must
bemaintainedfromtheperpendicularwalltothereplaceopening.
GAS SUPPLY
Installing a New Main Gas Cock (Check Local Code)
Each appliance should have its own manual gas cock.
A manual main gas cock should be located in the vicinity of the unit.
Where none exists, or where its size or location is not adequate,
contact your local authorized installer for installation or relocation.
Compounds used on threaded joints of gas piping shall be resistant
totheactionofliqueedpetroleumgases.Thegaslinesmustbe
checked for leaks by the installer. This should be done with a soap
solution watching for bubbles on all exposed connections, and if
unexposed, a pressure test should be made.
Never use an exposed ame to check for leaks. Appliance must
be disconnected from piping at inlet of control valve and pipe
capped or plugged for pressure test. Never pressure test with
appliance connected; control valve will sustain damage!
NOTE: Whenusingcopperorexconnectoruse,onlyapproved
ttings.
The appliance and its individual shut off valve must be disconnected
from 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).
CAUTION
Ifoneoftheproceduresresultsinpressuresinexcessof1/2psig
(14”w.c.)(3.5kPa)onthereplacegasvalve,itwillresultina
hazardous condition.
Checking Manifold Pressures
Both Propane and Natural gas valves have a built-in pressure
regulator in the gas valve. Natural gas models will have a manifold
pressureofapproximately3.5”w.c.(.871kPa)atthevalveoutlet
withtheinletpressure to the valve from a minimum of 4.5” w.c.
(1.120kPa)forthepurposeofinputadjustmenttoamaximumof
14.0”w.c.(3.484kPa).Propanegasmodelswillhaveamanifold
pressure approximately 10.0” w.c. (2.49kPa) at the valve outlet
withtheinletpressuretothevalvefromaminimumof10.8”w.c.
(2.68 kPa) for the purpose of input adjustment to a maximum of

FRAMING CONSTRUCTION BEGINS.
1. Choose unit location.

NOTE:Fireplaceframingcanbebuiltbeforeorafterthereplace
is set in place. Framing should be positioned to accommodate
wallcoveringandreplacefacingmaterial.Thereplaceframing
should be constructed of 2 x 4 lumber. The framing headers
mayrestonthereplacestandoffs.RefertoFigures 15 and
16 for minimum framing dimensions.
NOTE: When installing this unit against exterior wall, insulate to
applicable insulation codes.
3. Remove two screws which are accessed through the clearance
holes in the rear heat shield. See Figure 17. Hand bend the
rear stand-off as shown in Figure 18 and Figure 19. Replace
the two screws previously removed to secure stand-off to unit.

Vent Pipe Clearance
Note: Maintain all clearances to combustibles as shown in

For horizontal vent, maintain a minimum 1 inch clearance to
the bottom and sides of the vent, and 3 inches of clearance to
combustibles above the vent pipe. See Figure 24.

Vent Runs
Inplanningtheinstallationforthereplace,itisnecessarytoinstall
certain components before the appliance is completely positioned
and installed. These include the direct vent system, gas piping for
the appliance and the electrical wiring.
The appliance can be mounted on any of the following surfaces:
1. Aat,hardsurface
2. A raised wooden platform
3. Four corner supports (Example: Four concrete masonry blocks.)
These supports must be positioned adequate is made with
bottom standoffs). See local codes.
Note For Horizontal Vent Runs (Figure 25):
Aspecicwallthimble(seepartslistpage55)mustbeused
for horizontal vent installations through combustible wall.

Begin the vent system installation by selecting the type of venting
to be installed and the path that it will take. Verify that clearances
are met throughout the path of the venting system.
Determine how the vent system will be terminated out the side of
the house or through the roof. Verify clearances for the termination.
Whenselectingaventsystemforusewiththereplace,refertothe
“VentFireplace”sectioninthismanualtodeterminewhatsystems
are acceptable. Check all clearances and venting components.
Identifyproblemsexistingintheventsystem,ifany.Usepages20
to 27 for venting to eliminate issues after installation. Check pipe
diameteronventsystemandreplacetoverifythesizeisthesame.
NOTICE: All outer connection joints must be sealed with
aluminum tape, screws or silicone sealant rated above
300°F/149°C. The inner ue joints do not require any sealant.
