the bypass plug must be installed. The burner is shipped
configured for use in single line applications. No changes
to the oil pump are required for use in single line
applications.
General oil piping requirements
Location and installation of oil tanks, oil piping and
burners must follow:
- Local codes and regulations.

- In Canada, CSA B139.00, Installation of Oil-Burning
Equipment.
- In USA, NFPA 31, Standard for the Installation of

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.
Do not use Loctite or Teflon tape. Support oil lines as
required by codes.
