General oil piping requirements
•
Location and installation of oil tanks, oil piping and burners must
follow:
•
NFPA 31, Standard for the Installation of Oil-Burning
Equipment.
•
In Canada, CSA B139, Installation of Oil-Burning
Equipment.
•
Local codes and regulations.
•
Information provided with burner and fuel pump.
•
If any part of the fuel oil tank is above burner level, an anti-
siphon device must be used to prevent the flow of oil in case of
an oil line break.
•
Support oil lines as required by codes.
•
Make tank connections with swing joints or copper tubing to
prevent breakage in case the tank settles. Make swing joints so
they will tighten as tank settles. Non-hardening pipe joint
compounds should be used on all threads.
Do not use Teflon tape as an oil pipe sealant. It can
cause valves to fail, creating hazards. Use only flare
fittings. Do not use compression fittings. Failure to
comply could result in severe personal injury, death
or substantial property damage from oil leakage
and/or fire hazard.
•
Underground pipe must be run in a casing to prevent oil leaking
into the ground or under the floor. Check local codes for
information.
Oil piping connection at burner
•
Connect oil line to burner using a flare fitting.
Use of any connection other than a flare fitting at the
oil connection to the burner could result in a fuel oil
leak, with the potential for severe personal injury,
death or substantial property damage.
•
See local codes for appropriate arrangement and piping of filter,
control valves, etc. connecting to oil tank.
•
Refer to burner manual for oil system requirements. Verify that
suction lift does not exceed stated limit. Where lift exceeds limit
for a one-pipe system, use a two-pipe system as directed in
burner manual.
