Note: to determine the proper fuel line size, refer to the
fuel pump manufacturer’s instructions provided with
the burner. Refer to Figure 6 or Figure 7 for typical
installation layouts.
Installing the Oil Tank and Supply System
Figure 5. – Mounting Burner in Appliance
Connect fuel lines
Carefully follow the fuel unit manufacturer’s literature
and the latest edition of NFPA 31 for oil supply system
specifi cations (CSA B-139 in Canada).
Fuel supply level with or above burner –
The burner may be equipped with a single-stage fuel
unit for these installations. Connect the fuel supply to the
burner with a single supply line if you want a one-pipe
system (making sure the bypass plug is NOT installed in
the fuel unit.) Manual bleeding of the fuel unit is required
on initial start-up. If connecting a two-pipe fuel supply,
install the fuel unit bypass plug.

Figure 7. – Outside Buried Tank-Lift System
To further protect the fuel supply
system and reduce nozzle orifi ce
plugging, a dual fi ltration system can be installed. This
typically consists of a 50 micron primary fi lter, located
near the fuel tank and a secondary fi lter rated for at least
10 microns located near the burner.

Oil Leak and Fire Hazard
Install the oil tank following applicable standards in the
U.S. by referring to the latest edition of NFPA 31 or CSA-
B139 & CSA-B140 in Canada, and all authorities having
jurisdiction.
Do Not Use Tefl on Tape
Damage to the pump could cause impaired burner
operation, oil leakage and appliance soot-up.
Never use Tefl on tape on fuel oil fi ttings.
Tape fragments can lodge in fuel line components
and fuel unit, damaging the equipment and
preventing proper operation.
Use oil-resistant pipe sealant compounds. y
