The provisions of this Subpart apply to all oil burners, without regard to date of installation.

All controls shall be accessible for normal servicing and adjustment in position and shall be replaceable during normal servicing.

Burners shall be equipped with automatic primary safety controls to prevent abnormal discharge of oil at the burner in case of ignition failure or flame failure.

Parts of the burner that may normally come in contact with the operator's hand or arm during normal usage shall be free from sharp edges or projections and projecting screwheads or ends.

An adjustable or moving part shall be provided with a suitable locking device to prevent accidental shifting.

A small orifice or other opening in an oil supply system likely to become clogged shall be protected by a suitable strainer. A strainer employing an element other than a screen shall have a rated capacity not less than the maximum firing rate of the burner to which it is applied.

Tubing shall be arranged to avoid being physically damaged. A coupling or union which is disconnected for service shall be located so that any oil dripping from the connection will not drip or run onto electrical parts.

A petcock or valve which when opened will permit the discharge of fuel oil into the boiler room shall not be used.

A glass gage or sight feed, the breakage of which will allow the discharge of fuel oil from the fuel supply system, shall not be used.

The provisions of this Subpart apply only to oil burners installed before March 31, 1965.

On all manual or automatic oil-fired burners having a firing rate up to seven gallons per hour, the main flame trial-for-ignition period shall not exceed 90 seconds. Upon flame failure, the main oil valve shall close automatically within 90 seconds.

After the burner is manually lit the main flame shall be continually supervised while the burner is firing. The electrical circuit to the main fuel valve shall be automatically de-energized within four seconds after flame failure and the de-energized valve shall automatically clo…

The main flame trial-for-ignition period shall not exceed 30 seconds and the main flame shall be continually supervised while the burner is firing. Upon flame failure, the main oil valve shall close automatically within 30 seconds if the burner does not relight within this time.

The main flame trial-for-ignition period shall not exceed 15 seconds and the main flame shall be continually supervised while the burner is firing. Upon flame failure, the main oil valve shall close automatically within 15 seconds if the burner does not relight within this time.

The main flame trial-for-ignition period shall not exceed 30 seconds when the burner has a low firing rate start under 16 gallons per hour and shall not exceed 15 seconds when the burner does not have such a low firing rate start. The main flame shall be supervised continually wh…

If an automatic type oil-fired boiler is equipped with a proved pilot, regardless of the firing rate, such pilot shall be proved within 15 seconds. The burner shall be so designed and installed that the main oil valve shall open only after the pilot is proved and either such pilo…

The provisions of this Subpart apply only to oil burners installed after March 31, 1965.

For a burner which is equipped to start on low fire only and whose firing rate cannot properly be increased beyond the low firing rate until ignition of the low fire is proven, the term maximum firing rate used in this Subpart means the firing rate to the largest fire that can be…

On all manual or automatic oil-fired boilers having a firing rate of three gallons per hour or less, the main flame trial-for-ignition period shall not exceed 90 seconds. Upon flame failure, the main oil valve shall close automatically within 90 seconds.

After the burner is manually lit, the main flame shall be continually supervised while the burner is firing. The electrical circuit to the main fuel valve shall be automatically de-energized within four seconds after flame failure and the de-energized valve shall automatically cl…
