• Check minimum clearances against those shown by the appliance
manufacturer and by applicable building codes.
Combustion chamber — Burner retrofitting
Verify that the appliance combustion chamber provides at least the minimum
dimensions given in Table 2.
CAUTION
When retrofitting an appliance that has an unlined stainless
steel combustion chamber, chamber burnout could result from the use of a
high performance burner. Protect the chamber from high temperatures
through the use of "wet-pac" or a similar ceramic liner. Some equipment may
utilize a stainless steel combustion chamber that has been designed and
tested by the manufacturer for use with a flame retention burner, therefore
ceramic protection would not be necessary. Refer to appliance manufacturer’s
instructions. Failure to comply could result in damage to heating equipment.

Connect fuel lines
(continued)
WARNING
The oil supply inlet pressure to the fuel unit cannot exceed 3
psi. Install a pressure-limiting device in accordance with NFPA 31.
Fuel supply below the level of the burner
When the fuel supply is below the level of the burner, a two-pipe fuel supply
system is required. Depending on the fuel line diameter and horizontal and
vertical length, the installation may also require a two-stage pump. Consult the
fuel unit manufacturer's literature for lift and vacuum capability.
Fuel line installation
• Continuous lengths of heavy wall copper tubing are recommended.
Always use flare fittings. Never use compression fittings.
Always install fittings in accessible locations. Fuel lines should not run
•
against the appliance or the ceiling joists (to avoid vibration noise).
WARNING
Never use Teflon tape on any fuel fitting. Tape fragments can
lodge in fuel line components and fuel unit, damaging the equipment and
preventing proper operation.
Fuel line valve and filter
Install two high quality 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 filter.
NOTICE
Some states require these valves to be fusible-handle design
for protection in the event of fire. We recommend this as good industry
practice for all installations.
• Install a generous capacity filter inside the building between the fuel tank
shutoff valve and the burner, locating both the filter and the valve close to
the burner for ease of servicing. Filter should be rated for 50 microns or
less.
