Connect Oil Piping

Connect Oil Piping

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 fuel oil tank is above level of burner, an anti-siphon device must be used to prevent flow of oil in case of oil line break.

•Support oil lines as required by codes.

•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 Teflon tape as an oil
	pipe sealant. It can cause valves
	to fail, creating hazards. Do not use
	compression fittings, only flare fittings.

•Underground pipe must be run in a casing to prevent oil leaking into ground or under floor. Check local codes for information.

Oil piping connection at burner:

See FIGURE 15 for recommended connection at burner, allowing burner mounting door to swing open completely for servicing.
