jacket.
6.Installthe1/2”MPTtemperature/pressuregaugeintting
asshown.
7.Locateandinstalloutsideairtemperaturesensor.Location
ofthissensorshouldbeonthenorthsideofthehomeor
buildingandoutofdirectsunlight.Usethecablesupplied

Design:
Therstthingthatneedstobedoneisdecidingwhereand
howtheboilerwillbeinstalled.
Things that need to be taken into consideration are the
intendeduseoftheboilerforexample,istheboilergoingtobe
usedasyourprimaryheatingsystemorisitgoingtobeused
asasecondaryorbackupheatingsystem.Ifitistobeused
inconjunctionwithanexistingoilorgasboilersystemwillit
bepipedinparallelorinseries?Theanswerstotheseand
otherquestionscanbedeterminedbytalkingtoyourcertied
dealeroraqualiedHVACorplumbingcontractor.Thiswill
ensurethattheboilerisinstalledandpipedtoaccommodate
yourneedsandexpectations.
Consideration must be given to the venting as well as
electricalandclearancerequirements.(Clearancesmustbe
maintainedtocombustiblesandalsoforservice)
Makesurefansarenotusedinthefuelstoragearea,unless
theyareinstalledsoasnottocreateanegativepressurein
theroomwherethesolidfuelburningapplianceislocated.
Assembly
Floor Protection:
The striped area indicates the minimum required floor
protection area if the boiler is going to be placed on a
combustibleoor.Itrequires40”X55”(US)or42”X55”(CAN)
