IMPORTANT:
PLEASE READ THE FOLLOWING CAREFULLY
It is normal for replaces fabricated of steel to
give off some expansion and/or contraction noises
during the start up or cool down cycle. Similar
noises are found with your furnace heat exchanger
or car engine.
IMPORTANT:
PLEASE READ THE FOLLOWING CAREFULLY
It is not unusual for gas replace to give off some
odor the rst time it is burned. This is due to the
manufacturing process.

VENT INSTALLATION
INSTALLATION PLANNING
Therearetwobasictypesofdirect-ventinstallation:
 • HorizontalTermination
 • VerticalTermination
Itisimportanttoselecttheproperlengthofventpipeforthetypeofterminationyouchoose.Itisalsoimportanttonotethe
wallthickness.
FOR HORIZONTAL TERMINATION
Selecttheamountofverticalrisedesired.Allhorizontalrun
ofventingmusthave1/4"riseforevery12"ofruntowards
thetermination.
Youmayuseuptothree90°elbowsinthisventcongura-
tion. See Horizontal Termination Congurations on pages
20and21.
FOR VERTICAL TERMINATION
Measurethedistancefromthereplaceoortotheceiling.Addtheceilingthickness,theverticalriseinanatticorsecond
story,andallowforsufcientventheightabovetheroofline.
NOTE: You may use two 45° elbows in place of a 90° elbow. You must follow rise to run ratios when using
45° elbows. The appliance is approved for use with three 90° elbows maximum or a combination of 90°
and 45° elbows up to a maximum of 270°.
Fortwo-storyapplications,restopsarerequiredateachoorlevel.Ifanoffsetisneededintheattic,additionalpipeand
elbowswillberequired.
Youmayuseachasewithaventterminationwithexposedpipeontheexteriorofthehouse.SeeInstalling Vent System in
a Chasebelow.Ifpipeisenclosedinchase,itisnotexposed.
Itisveryimportantthattheventingsystemmaintainitsbalancebetweenthecombustionairintakeandtheuegasexhaust.
Certainlimitationsapplytoventcongurationsandmustbestrictlyfollowed.

HOW TO USE THE VENT GRAPH
TheVentGraphshouldbereadinconjunctionwiththefollowing
ventinstallationinstructionstodeterminetherelationshipbetween
theverticalandhorizontaldimensionsoftheventsystem.
1. Determinetheheightofthecenterofthehorizontalventpipe
exiting through the outer wall. Using this dimension on the
SidewallVentGraphbelow,locatethepointintersectingwith
theslantedgraphline.
2. Fromthepointofthisintersection,drawaverticallinetothe
bottomofthegraph.
3. Selecttheindicated dimension,andposition thereplacein

TIONS
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.
TheVentGraph,showingtherelationshipbetweenverticalandhorizontalsidewallventing,willhelptodeterminethevari-
ousdimensionsallowable.See page 17.
Minimum clearance between vent pipes and combustible materials is 3" on top and 1" from bottom and sides unless
otherwise noted (Exception: Outside wall with restop: 1" all around pipes are allowed).
Whenventtermination exits throughfoundationsless than 20" belowsidingoutcrop, the vent pipemust ush up with
thesiding.
Itisbesttolocatethereplaceinsuchawaythatminimizesthenumberofoffsetsandhorizontalventlength.
Thehorizontalventrunreferstothetotallengthofventpipefromtheuecollarofthereplace(orthetopofthetransition
elbow)tothefaceoftheouterwallorthemountingangeofthetermination.
