IMPORTANT INFORMATION
Taking Delivery of Equipment:
When taking delivery of your equipment, please be sure to check the shipment for any
potential damages (MorrHeat is not responsible for any damaged shipments if signed for
non-damaged).Ifanydamageisidentiedupondelivery,eithersignforasdamagedgoods

It is recommended to use a lter or some kind of strainer when pouring waste oils into the storage tank(s).
This will increase chances of catching any particulates prior to the pump lter(s) to insure a cleaner fuel
source.

VENTING INSTALLATION
1. When installing the vent pipe, be sure all connections are fastened correctly to insure no
leaks and proper draft is achieved. Minimum draft through the unitis,-.02-whencheck-
ingthroughthesightorameinspectionportdirectlyabovetheburnerassembly,with
draftmeter.Draftupthestackmustbe-.04to-.06inchesofwatercolumnwhencheck-
ing a draft meter for proper draft readings.
2. Ifproperordesireddraftisn’teasilyachieved,athirdpartydraftinducerorpowervent
may be needed to prevent back draft from occurring (not provided).
3. Install a barometric damper (NOT included) in the stack only if the draft up the stack
exceeds-.08.Draftupthestackmustbe-.04to-.06inchesofwatercolumn.Checkwith
draftmeterbetweenthetopoftheheateranddamper.The draft should be a minimum of
-.02-checkedthroughameinspectionport.
4. Keepthedraftmoving.Ifdraftistoosloworbottlesup,thiscouldcreateabackdraftand

Initial Start Procedure
1. Make sure the heating unit and all components have been properly and securely installed.
2. Checkthatallelectricalconnectionsandhook-upsareproperlywiredandconnected.
3. Itisrecommendedpriortoprimingthefuelpumpandbleedingtheairtopre-llthefuel

fuellinestoeliminateanypotentialleaksinthelineorttings.Consistentfuelsupplytothe
burner is very important.
4. Check that venting connections are properly installed and connected from the heating unit.
5. While rst starting the unit it may take several minutes to get the oil in the pre heater
block up to temperature. Once the oil reaches the desired temperature, oil is then supplied
through the fuel pump assembly and burner assembly. Make sure burner and pump are
turned on.
6. Optimaldraftwhenrunningtheunitisanotherveryimportantpartoftheprocess.Besure
