General Oil piping requirements
Location and installation of oil tanks, oil piping and
burners must follow:
- Local codes and regulations.
- Information provided with burner and fuel pump.
- In Canada, CSA B139.00, Installation of Oil-Burning
Equipment.
- In USA, NFPA 31, Standard for the Installation of
Oil-Burning Equipment.
WARNING
Do not use Teflon tape as an oil pipe sealant. It can
cause valves to fail, creating hazards. Do not use
compression fittings.
Underground oil line piping must be encased to prevent
oil leaking into ground. Check local codes for information.
If any part of fuel oil tank is above burner level, an anti-
siphon device must be used to prevent flow of oil in case
of oil line break.
Make tank connections with swing joints or copper tubing
to prevent breaking 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.
Support oil lines as required by codes.
Oil piping connection at burner
See illustration above for recommended connection at
