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, installation of an
anti-siphon device is highly recommended to 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.
• Underground pipe must be run in a casing to pre-
vent oil leaking into ground or under floor. Check
local codes for information.
Oil piping connection at burner
• See Figure 21 for recommended connection at
burner, allowing burner mounting door to swing
open completely for servicing.
