Understanding the Oil Primary Control (CB-350-CTB and CB-500-CTB)
NOTE: This is a new control featuring the ability to activate a remote alarm in case of lock-out or
latch-up.
The oil primary control will go into safety lock-out and shut the burner off when it detects flame-out
during burner operation. The oil primary control will then wait approximately one minute and attempt
to re-ignite the burner (recycle mode). If the burner does not re-ignite, the control will shut the burner
off on safety. The following procedure explains what should be done when this occurs.
It is very
important that you follow these instructions precisely when resetting the safety on the primary control
and restarting the burner.
Resetting the Oil Primary Control (CB-551-H3 and CB-551-H5 Burners)
DANGER! DO NOT reset the oil primary control if oil mist is present in the combustion
chamber or when the combustion chamber is hot! DO NOT operate your CTB if excess oil,
oil vapor or fumes have accumulated in or near your boiler. As with any oil burning unit, improper
operation may result in a fire or explosion hazard.
1. Refer to Figure 7B.
2. Check the combustion chamber for fuel mist by shining a flashlight through the observation port.
If you see fog (fuel mist) in the chamber, DO NOT push the reset button.
3. If the combustion chamber is hot, allow the boiler to cool for at least 30 minutes. DO NOT
push the reset button.
4. When you are sure that all fuel mist has cleared and the boiler has cooled, push in and hold the
reset button for one second, then release. This will reset the control at any time during its operation.
ATTENTION: It is very
important that the "F" and
"T" terminals of the Oil
Primary Control are wired
exactly as shown in Figure 7B.
NEVER connect jumper wires
to these terminals or severe
damage may occur to the Oil
Primary Control.
