Important: For the Pentair Thermal Management warranty to be
valid,youmustcomplywithalltherequirementsoutlinedinthese
guidelines.
Allthermalanddesigninformationprovidedhereisbasedupona
“standard” installation with heating cable fastened to an insulated
pipe. For any other application or method of installation, consult
Pentair Thermal Management at [phone].
HEATING CABLE SELECTION AND DESIGN
Make sure that the heating cable being used is suitable for your
application.RefertotheCommercialandResidentialApplicationand
Design Guide (H53585) for heating cable application information.
1. Determine the heating cable type.
UseTable1toselectheatingcablesforinsulatedmetalpipes.Use
Table2toselectheatingcablesforinsulatedplasticpipes.Read
across the table to find your pipe size, then drop down to the line
corresponding to the lowest air temperature for that application and
the correct insulation thickness. The cell at that intersection has a
particularshadingandmayhaveanumber.Theshadingindicates
whichheatingcabletouse(keytotheshadingappearsabovethetable
headings). A number represents the spiraling ratio (feet of heating
cable per foot of pipe).
If no number appears in the cell, straight trace the pipe. If a number
does appear in the cell, spiral trace the pipe.
If your spiraling ratio is 2.0, multiple trace the pipe using two straight
traces at the 4 o’clock and 8 o’clock positions.
If your spiraling ratio is 3.0, multiple trace the pipe using three
straight traces at the 11 o’clock or 1 o’clock position, and at the 4
o’clock and 8 o’clock positions.
Example 1:
Pipe size: 1 in
Lowestairtemp.: 0°F
Insulation thickness: 1/2 in
Metal pipe:
WinterGard H311
Plastic pipe: WinterGard Plus H611, H621
WinterGard Wet H612, H622
Example 2:

2. Cut the heating cable to length.
•Cuttheheatingcabletothelengthrequired.Thiscanbedone
beforeorafterthecableisattachedtothepipe.Leaveaminimum
of1footextraheatingcableforconnectiontopower.Forsplice
andteeconnections,leaveaminimumof1footforeachsection
of heating cable. WinterGard heating cable can be cut to length
without affecting its heat output per foot.
•Protecttheheatingcableendsfrommoistureormechanical
damageiftheywillbeleftexposedbeforeconnection.
3. Position and attach heating cable to pipe.
•Besureallpipingtobetracedisdry.
•Installheatingcable,usingstraighttracing,spiraling,ormultiple
tracing according to the “Heating cable selection and design”
section on page 3.
•Forstraighttracing,installtheheatingcableonalowerhalfofthe
pipe;forexample,inthe4o’clockor8o’clockposition.
•Besuretoinstalltheadditionalheatingcablerequiredforvalves,
flanges,etc.asindicatedinStep2ofthe“Heatingcableselection
and design” section.
•Whenthedesigncallsforspiraling,beginbysuspendingaloop
every10feetasshowninFigure1.Todeterminethelooplength,
obtain the spiral factor from Table 1 or 2 and multiply by 10. For
example,ifaspiralfactorof1.3iscalledfor,leavea13-footloop
ofheatingcableatevery10-footsectionofpipe.Grasptheloop
initscenterandwrapitaroundthepipe.Evenoutthedistance
betweenspiralsbyslidingthewrapsalongthepipe.Useglass
tapetosecurethecenterofthelooptothepipe.Securethe
heating cable flat to the pipe to obtain good contact.
•TapeWinterGardheatingcabletothepipeat2-footintervalsusing
RaychemH903fiberglassapplicationtapeornyloncableties.Do
notusevinylelectricaltape,ducttape,metalbands,orwire.
4. Install heating cable end seals, splices, tees, and power

plugging in.
•Ifsplicingorteeing,useonlytheH910WinterGardSpliceandTee
Kittosatisfycodeandagencyrequirements.
•H900kitassemblyinstructionsbeginonpage9.
5. Check the installation.
•Priortoinstallingthermalinsulation,makesuretheheating
cable is free of mechanical damage (from cuts, clamps, etc.) and
thermaldamage(fromsolder,overheating,etc.).
•Visuallycheckallpowerconnections,endseals,splices,andtees.
•Usingamegohmmeter,testeachcircuitaccordingtothe

weather-proofed thermal insulation.
• Ensurethat type and thickness of the insulation are in accordance
with the information in the heating cable selection tables on
page3andthatallpipework—includingvalves,joints,wall
penetrations, and other elements—has been fully insulated.
•Minimize the potential for mechanical damage to the heating cable
afterinstallationbyinstallingtheinsulationassoonasyouhave
checked the cable installation.
7. Mark the installation.
•Place“Warning”labelsforpipetraceapplicationsontheouter
surfaceoftheinsulationat10-footintervals(onalternating
sides of the pipe) to indicate the presence of WinterGard electric
heating cable. Additional labels and application tape are contained
intheH903kit.
8. Check the installation
• Priortopowering,checktobesuretheheatingcableisfreeof
mechanical damage (cuts, clamps, etc.).
• Visuallycheckallpowerconnections,endseals,splices,andteesfor
proper installation.
•Usinga Megohmmeter, test each circuit according to the instructions
in the “Heating cable testing and maintenance” section below.
HEATING CABLE TESTING AND MAINTENANCE
Pentair Thermal Management recommends that the insulation
resistance between the bus wires and the heater grounding braid
or metal pipe should be checked during installation using a 2500-
Vdcmegohmmeter.Minimumreadingshouldbe1000megohms,
regardless of length.
Recordtheoriginalvaluesforeachcircuit.Takeadditionalreadings
during regularly scheduled maintenance and compare to the original
value.Ifthereadingsfallbelow1000megohms,inspectcablesand
insulation for signs of damage.
If physical damage is found, the entire damaged section must be
removedandanewsectionofheatingcablesplicedinusingonly
approvedWinterGardH910splicekits.Donotrepairthedamaged
heating cable section.
If physical damage cannot be found, the complete circuit should be
removedandreplacedwithnewWinterGardheatingcable.
WARNING: Shock and Fire Hazard. Damaged heating cable
or components can cause electrical shock, arcing, and fire.
Do not attempt to energize damaged cable or components.
Replace them immediately using a new length of heating
cable and the appropriate WinterGard accessories.

HEATING CABLE INSTALLATION
1. Prepare for installation.
• Storetheheatingcableinaclean,dryplace.
• UseonlythefollowingPentairThermalManagementaccessoriesto
satisfycodeandagencyrequirements:
-H900WinterGardPlug-inPowerConnectionKit(withendseal)
-H910WinterGardSpliceandTeeKit(ifsplicingorteeing)
-H915DownspoutHangers
-H913/H914RoofClips
• Carefullyplantheroutingoftheheatingcableforroofandgutter
de-icing.
• Makecertainguttersanddownspoutsarefreeofleavesandother
debris.
2. Cut the heating cable to length.
• Cuttheheatingcabletothelengthrequired.Thiscanbedonebeforeor
afteritisinstalled.Leaveaminimumof1footextraheatingcablefor
connectiontopower.Forspliceandteeconnectionsleaveaminimum
of 1 foot for each section of heating cable. WinterGard heating cable
can be cut to length without affecting its heat output per foot.
• Protecttheheatingcableendsfrommoistureandmechanicaldamage
if they will be leftexposedbeforeconnection.
3. Position and attach the heating cable.
On roofs
• Looptheheatingcableontheoverhangareaoftheroof.Thisisthe

• UseWinterGardH913/H914roofclipstoattachheatingcabletothe
roofsurface.Onekitcontainstendoubleroofclipsforapproximately
7linearfeetofroofedge.OneH914kitcontains50roofclipsfor
approximately35linearfeetofroofedge.
For flat roofs, the heating cable can be spaced as needed to create
runoffpathsformeltingiceandsnow.Usesingle-endedclipslocated
at3-footintervalstosecurethecabletotheroof.
 Roofclipsmaybeattachedtoashakeorshingleroofwithnailsor
screws.Resealthenailorscrewholesifnecessarybeforeinstalling
heatingcableintheclips.Roofclipsmaybeattachedtoametalroof
usingscrew,nailoradhesive.(SeeH56723installationinstructionfor
more details.)
• Abarrier(snowfence)canbeplacedontheroofabovetheheating
cable.Thispreventsdamagetothecableandkeepstheinstallation
from coming loose due to ice slides. If desired, the heating cable can
beattachedtothebarrierwithUV-resistantcableties,insteadof
using roof clips. Do not use wire or other materials because they may
damage the heating cable.
In gutters and downspouts
• Runheatingcablealongguttersandintodownspouts,endingbelow
thefreezinglevel.Permanentattachmentofthecabletothegutter
bottomisnotnecessary.Looptheheatingcableindownspoutsif
convenient,suchaswhenthedownspoutisnotattheendoftherun,
orusetheH910spliceandteekittoteedownthedownspout.
• UseWinterGardH915downspouthangerstoprotecttheheatingcable
fromfrayingandfromdamagefromsharpedgesandtoprovidestrain
relief.RefertotheH915kitinstructionsforinstallationdetails.
• UseWinterGardH913/H914roofclipstorouteheatingcableinto
andoutofthegutterinsuchawayastopreventabrasiontothe
cable. Protect all cable that protrudes past the lower opening of the
downspout.

4. Install heating cable end seals, splices, tees, and power connection.
•Installallendseals,splices,tees,andpowerconnectionpriorto
plugging in.
•FollowtheH900kitinstallationinstructionsbeginningonpage9.
•Useonlyweatherproofjunctionboxesapprovedforwetlocations
when installing WinterGard H612 and H622 heating cable with the
H900PowerConnectionKitforroofandgutterapplications.
5. Mark the installation.
A label indicating the presence of electric de-icing and snow-
meltingequipmentonthepremisesisincludedwiththisunit.The
labelmustbepostedattheelectricaloutletcover.Thelabelmust
beclearlyvisible.
6. Check the installation.
•Priortopowering,checktobesuretheheatingcableisfreeof
mechanical damage (cuts, clamps, etc.).
•Visuallycheckallpowerconnections,endseals,splices,andtees
for proper installation.
•Usingamegohmmeter,testeachcircuitaccordingtothe
instructions in the “Heating cable testing and maintenance”
section below.
HEATING CABLE TESTING AND MAINTENANCE
Makesurethatgutteranddownspoutsarefreeofleavesandother
debris prior to the winter season.
Pentair Thermal Management recommends that the insulation
resistance between the bus wires and the heating cable grounding
braid or metal pipe should be checked during installation using a
2500-Vdcmegohmmeter.Minimumreadingshouldbe1000megohms,
regardless of circuit length.
Recordtheoriginalvaluesforeachcircuit.Takeadditionalreadings
during regularly scheduled maintenance and compare to the original
value.Ifthereadingsfallbelow1000megohms,inspectheatingcables
and insulation for signs of damage.
If physical damage is found, the entire damaged section must be
removedandanewsectionofheatingcablesplicedinusingonly
approvedWinterGardH910splicekits.Donotrepairthedamaged
heating cable section.
If physical damage cannot be found, the complete circuit should be
removedandreplacedwithnewWinterGardheatingcable.
WARNING: Shock and Fire Hazard. Damaged heating cable or
components can cause electrical shock, arcing, and fire. Do
not attempt to energize damaged cable or components.
Replace them immediately using a new length of heating cable
and the appropriate WinterGard accessories.
ELECTRICAL PROTECTION
Voltage rating
H612 110–120Vac
H622 208–240Vac
Ground fault protection:
PentairThermalManagementandnationalelectricalcodesrequire
ground-faultequipmentprotectiononeachheatingcablebranch
circuit. To reduce the risk of fire caused by damage or improper
installation,circuitbreakerssuchasSquareDQO-EPDandQOB-
EDPDorequivalent,witha30-mAtriplevel,shouldbeused.
Alternativedesignsprovidingcomparablelevelsofground-fault
protection may also be acceptable. For technical assistance, call
