On the outside of the home use a 90° elbow pointed
downward with a
1/4 ” mesh screen over its opening.
The air inlet elbow must be located above the snow
line and in such a way as to prevent leaves and/or
other debris from blocking the air fl ow. Such debris
will prevent proper operation of the burner. Refer to
local codes for proper location of inlet.

Section: Prepare the Burner
Prepare the Burner
General
In most cases, the burner is ready to mount to the
appliance. There can be situations where the burner
needs to be reconfi gured to perform properly in the
appliance. Review the appliance manufacturer’s
specifi cations prior to installing to determine if any
modifi cation is required to properly confi gure the burner.
Instruction on how to perform the following burner
preparation tasks can be found in the Professional
Maintenance section.
Remove / install burner nozzle
Check head/air adjusting plate ○
○
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

Damage to the pump could cause impaired burner
operation, oil leakage and appliance soot-up.
Do Not Use Tefl on Tape
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.
For fuel line installation, continuous lengths of heavy
wall copper tubing are recommended. Always use fl are
fi ttings. Never use compression fi ttings.
Note: to determine the proper fuel line size, refer to the
fuel pump manufacturer’s instructions provided with
the burner. Refer to Figure 4 or Figure 5 for typical
installation layouts.
Always install fi ttings in accessible locations. To avoid
vibration noise, fuel lines should not run against the
appliance or ceiling joists.
Fuel Line Valves and Filter
Install two high quality, oil duty rated, fusible handle
design shutoff valves in accessible locations on the oil
supply line. Locate one close to the tank and the other
close to the burner, upstream of the fi lter for service
access.
