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

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
