ELECTRICAL SUPPLY
Verify that the power connections available are correct for the Unit. All power must be supplied
through the disconnect.
INSTALLING THE OPTIONAL THERMOSTAT
Plug the thermostat directly into the receptacle. WARNING: THE RECEPTACLE IS USED FOR
INSTALLING THE THERMOSTAT ONLY! THIS IS NOT A POWER SOURCE.
CONNECT THE FUEL LINE(S) - REFER TO CHART BELOW FOR FUEL LINE LENGTH
WARNING
Install the oil lines using the following guidelines. Failure to comply could lead to equipment
damage and present a risk of sever personal injury, death or substantial property damage
due to leakage of oil and potential fire hazard.
Use only flare fittings at joints and connections. Never use compression fittings.
Install fittings only in accessible locations to assure any leak will be detected.
Where joint sealing is needed, use only pipes dope. Never use Teflon tape. Tape strands
can break free and damage the fuel unit.
On two-pipe oil systems verify that the suction line vacuum does not exceed the fuel
manufacturer's recommendation.
WARNING
Do not operate the burner unless a return line or a by-pass loop is installed. Failure to
follow this guideline will cause damage to the fuel seals and consequent fuel leakage. This
could result in severe personal injury, death or substantial property damage.
OIL SUPPLY / RETURN LINES
Install the oil tank lines in accordance with all applicable codes.
Use continuous lengths of heavy wall copper tubing, routed under the floor, where possible. Do not attach
fuel lines to the fuel unit or to the floor joists if possible. This reduces vibration and noise transmission
problems.
Install a high quality shut-off valve in an accessible location on the oil supply line. Locate one valve close
to the tank.
