SAFETY INFORMATION FOR USERS OF LP-GAS
LP-Gas(Propane)isaammablegaswhichcancauseresand
explosions.Initsnaturalstate,propaneisodorlessandcolorless.
Youmaynotknowallthefollowingsafetyprecautionswhichcan
protectbothyouandyourfamily from an accident. Read them
carefullynow,thenreviewthempointbypointwiththemembers
ofyourhousehold.Someday,theremaynotbeaminutetolose,
everyone’ssafetywilldependonknowingexactlywhattodo.If,
after reading the following information, you feel you still need
moreinformation,pleasecontactyourgassupplier.
LP-GAS WARNING ODOR
If a gas leak happens, you should be able to smell the gas because of the odorant put in the LP-Gas.
That’s your signal to go into immediate action!
• Do not operate electric switches, light matches, use your
phone.Donotdoanythingthatcouldignitethegas.
• Geteveryoneoutofthebuilding,vehicle,trailer,orarea.Do
that IMMEDIATELY.
• Closeallgastankorcylindersupplyvalves.
• LP-Gasisheavierthanairandmaysettleinlowareassuch
asbasements.Whenyouhavereasontosuspectagasleak,
keepout ofbasements andother lowareas.Stayoutuntil
reghtersdeclarethemtobesafe.
• Useyourneighbor’sphoneandcallatrainedLP-Gasservice
personand theredepartment. Eventhoughyou maynot
continuetosmellgas,donotturnonthegasagain.Donot
re-enterthebuilding,vehicle,trailer,orarea.
• Finally,lettheservicemanandreghterscheckforescaped
gas.Havethemairouttheareabeforeyoureturn.Properly
trainedLP-Gasservicepeopleshouldrepairtheleak,then
checkandrelightthegasapplianceforyou.
NO ODOR DETECTED - ODOR FADE
Somepeoplecannotsmellwell.Somepeoplecannotsmellthe
odorofthechemicalput into the gas.You must ndoutifyou
cansmellthe odorant inpropane.Smokingcan decrease your
abilitytosmell.Beingaroundanodorforatimecanaffectyour
sensitivityorabilitytodetectthatodor.Sometimesotherodorsin
theareamaskthegasodor.Peoplemaynotsmellthegasodor
ortheirmindsareonsomethingelse.Thinkingaboutsmellinga
gasodorcanmakeiteasiertosmell.
TheodorantinLP-gasiscolorless,anditcanfadeundersome
circumstances.Forexample,ifthereisanundergroundleak,the
movementofthegasthroughsoilcanltertheodorant.Odorants
inLP-Gasalsoaresubjecttooxidation.Thisfadingcanoccurif
thereisrustinsidethestoragetankorinirongaspipes.
Theodorant inescaped gascanadsorborabsorb ontoor into
walls,masonryandothermaterialsandfabricsinaroom.That
will take some of the odorant out of the gas, reducing its odor
intensity.
LP-Gas may stratify in a closed area, and the odor intensity
could vary at different levels. Since it is heavier than air, there
may be more odor at lower levels.Always be sensitive to the
slightestgasodor.Ifyoudetectanyodor,treatitasaseriousleak.
Immediatelygointoactionasinstructedearlier.
SOME POINTS TO REMEMBER
• Learn to recognize the odor of LP-gas. Your local LP-Gas
Dealercangiveyoua“ScratchandSniff”pamphlet.Useit
tondoutwhatthepropaneodorsmellslike.Ifyoususpect
that your LP-Gas has a weak or abnormal odor, call your
LP-Gas Dealer.
• If you are not qualied, do not light pilot lights, perform
service,ormakeadjustmentstoappliancesontheLP-Gas
system.Ifyouarequalied,consciouslythinkabouttheodor
ofLP-Gaspriortoandwhilelightingpilotlightsorperforming
serviceormakingadjustments.
• Sometimesabasementoraclosed-uphousehasamusty
smellthatcancoveruptheLP-Gasodor.Donottrytolight
pilotlights,performservice,ormakeadjustmentsinanarea
wheretheconditionsaresuchthatyoumaynotdetectthe
odoriftherehasbeenaleakofLP-Gas.
• Odorfade,duetooxidationby rust or adsorption on walls
of new cylinders and tanks, is possible. Therefore, people
shouldbeparticularly alert and carefulwhennew tanks or
cylindersareplacedinservice.Odorfadecanoccurinnew
tanks,orreinstalledoldtanks,iftheyarelledandallowed
to set too long before relling. Cylinders and tanks which
have been out of service for a time may develop internal
rustwhichwillcauseodorfade.Ifsuchconditionsaresus-
pectedtoexist,aperiodicsnifftestofthegasisadvisable.If
youhaveanyquestionaboutthegasodor,callyourLP-gas
dealer.A periodic sniff test of the LP-gas is a good safety
measureunderanycondition.
• If, at any time, you do not smell the LP-Gas odorant and
youthinkyou should,assumeyou havealeak.Thentake
the same immediate action recommended above for the
occasionwhenyoudodetecttheodorizedLP-Gas.
• If you experience a complete “gas out,” (the container
is under no vapor pressure), turn the tank valve off
immediately. If the container valve is left on, the container
maydraw in someair through openingssuch aspilotlight
orices. If this occurs, some new internal rusting could
occur. If the valve is left open, then treat the container as
anewtank.Always be sure your container isundervapor
pressure by turning it off at the container before it goes
completely empty or having it relled before it is
completelyempty.

Leak Testing
WARNING - FIRE OR EXPLOSION HAZARD
Never test for leaks with an open ame. Check all
connections using a commercially available soap so-
lution. A re or explosion may result causing prop-
erty damage, personal injury or loss of life. Failure
to follow the safety warnings exactly could result in
serious injury, death or property damage.
Aftergaspipingtothereplaceiscomplete,allconnectionsmust
betestedforgasleaks.Thisincludespipeconnectionsatthemain
gasvalve,emergencyshutoffvalveandexiblegasconnectors(if
applicable).Thesoapandwatersolutioncanbeappliedoneach
jointorunionusingasmallpaintbrush.Ifanybubblingisobserved,
theconnectionisnotsealedadequatelyandmustberetightened.
Repeatthetighteningandsoapcheckprocessuntilthebubbling
ceases.
Important Note:
When pressure testing the gas supply lines at pressures
greater than ½ psig (14 in. w.c.), the gas supply piping system
must be disconnected from the replace to prevent damage
to the gas control valve. If the test pressure is less than or
equal to ½ psig (14 in. w.c.), close the manual shut-off valve.
Pressure Testing of the Gas Supply System
1. Tochecktheinletpressuretothegasvalve,a1/8inchN.P.T.
pluggedtapping,accessiblefortestgaugeconnection,must

VENTING REQUIREMENTS
WARNING
This replace must not be vented with any other appliances,
even if that appliance is of the condensing type. Common
venting can result in severe corrosion of other appliances
or their venting and can allow combustion gases to escape
through such appliances or vents. Do not vent the replace
into a replace chimney or building chase.
WARNING
Upon completion of the installation, carefully inspect the en-
tire ue system to assure it is properly sealed. DO NOT use
any vent material other than what is specied in this manual.
Leaks in the ue system can result in serious personal injury
or death due to exposure of ue products, including carbon
monoxide.
TheMantisis classied as a“CategoryIV” appliance, which re-
quires special venting materials and installation procedures. In-
stallationscanbeConventional(1-pipe)andDirectVent(2-pipe).
Ventingmustbecompletedwith1-1/2inchdiameterpipe.Inse-
lecting a location for installation, it is necessary to provide ade-
quateclearancesforservicingandproperinstallation.
AllventandcombustionairpipesandttingsmustbeSchedule
40PVCandmeettheANSI/ASTMStandardD1785.Cementmust
conformtoASTMStandardD2564.
Maximum Vent Length is 40 feet with (3) 90° elbows. The
minimum vent length is 12 inches.Each90°elbowusedin
theventsystemwillbetheequivalentto3feet,andeach45°
elbowis equivalentto 1.5feet,whichshouldbeaddedto the
overall vent length. See Table 1.
It is recommended that the Mantis Power-Vent High-Efciency
Fireplacebelocatedonanexteriorwallforeaseofventing.The
ueexhaustpipeandinletairpipeshouldbelocatedbetweenwall
studs.Therequiredopeningforventingis1-7/8inchindiameter
for1-1/2inchPVCpipe.
Theminimumdistancefromthecenteroftheventcaptothenear-
estoutsidecornerorobstructionis12inches.Theueoutletmust
beatleast12inchesfromanyopeningwhichuegasescoulden-
terthebuilding.SeeFigure1.Theueoutletmustbeaminimum
distanceof6feetfromanypressureregulator.
Thebottom ofthe exhaustventterminalandthe airintake shall
be located at least 12 inches above grade and must be vented
outside.Itisrecommendedtheexhaustandintakebelocated12
inches from the maximum snow level.
Theuepipemustbesupportedonhorizontalventruns.Theue
pipeneedstobesupportedevery3feet.Allhorizontalrunsofthe
uemustbepitched¼inchperfooteithertowardsthereplaceor
awayfromthereplace.
Note: Iftheventrundipsorsags,condensationmaybecome
trappedandcausetheunittonotoperateproperly.
The minimum vent length protruding from outside the wall is 6
inches.Fortwo-pipeinstallation,aminimumdistanceof3inches
andmaximumdistanceof24inchesmustbemaintainedbetween
thepipes.SeeFigures2and3.
Single ue (one-pipe) installations must have a minimum clear-
anceof2inchesonthebackofthereplaceforcombustionair.
Note: If vent length requirements are not followed, the unit
will not operate properly.

Installation of the Colinear Transition Plate
1. Attachtheplatetochimneychase, at roof, or outside wall
withfour(4)screws.Useoutdoorsealanttosealthetransition
platetothesurface.
2. Cut inlet air pipe and ue exhaust pipe to correct lengths.
Forverticalterminationsthroughtherooforchimney,theair
intake and exhaust pipe termination must be a minimum of
12 inches above the roof line. It is recommended that the
airintakeandexhaustpipeterminationbe12inchesabove
themaximumexpectedsnowlevel.SeeFigures13and14.
Whenventingvertically,theexhaustpipeterminationmustbe
aminimumof3inchesabovetheairintake.Alsorefertolocal
codes. For horizontal termination through outside walls, the
minimumpipelengthis9inchesforexhaustpipetermination
and6inchesfortheairintake.
3. Attachtheueandinletairpipestothetransitionplate.Use
theappropriateprimerandcementtopermanentlybondthe
jointsandthepipestothetransitionplate.

Max Vent Run - 40 ft. Equivalent With Three (3) 90° Elbows
Special Note: The vent terminal 90° elbow and rst 90° elbow
off back of the fireplace, when within 6” (15.2 cm), do not con-
tribute to the overall vent length measurement. For each 45°
elbow installed in the horizontal run, the length of the hori-
zontal run MUST be reduced by 1.5 feet (45 cm). This does not
apply if the 45° elbows are installed on the vertical part of the
vent system. Reduce the length of the horizontal run 3 feet
(91.4 cm) for every 90° elbow.
