Fuel Oil Models
OIL TANK:
1. Since tanks vary in size and fixtures, you may need to make adaptations to use the
parts supplied. Placing the tank to allow gravity flow to burners is ideal but limit line
pressure head to 3 psi (nfpa rule) or no more than 10 psi (pump vendor limit) at the
burner pumps. Pressure limit applies to supply and return lines at pumps. If gravity
feed is not used limit the burner pump lift to 10 feet head.
vacuum and is more suspect to air leaks and erratic starting of burner. Assure
fittings are sealed.
2. It is important that a filter be provided in the Supply line between the tank and the
incinerator. The Return fuel line allowing fuel back to the tank must be open for free
flow. Placing valves or other devices in this line is not suggested as accidental
dead heading and resistance can ruin oil pumps.
3. The fuel supply outlet to the burners may come from the underside of the storage
tank or be pulled up through a dip tube from the top. If problems from condensation
are anticipated the moisture will collect in the bottom of the tank and can cause
misfiring or rust in the burner fuel pumps leading to failure. Drain water or extract it
before it gets to the filter or burner pump.
PIPING:
1. A flaring connection is used on ends of the copper tubing.
Assemble 1/2" copper tubing to burners as shown.
2.
Never use thread tape, use liquid or paste sealant.
3.
Factory prebuilt piping is optional and must be ordered at time of purchase.
