SECTION 7: RESETTING THE FURNACE AND BURNER
The Oil Primary Control
Figure 7A - Oil Primary Control
ATTENTION: Never touch a jumper
wire from an "F" terminal to a "T"
terminal on the oil primary control.
This will severely damage your
primary control.
Understanding Furnace/Burner Shutdowns
( See Appendix B for additional information )
The oil primary control will go into safety lockout and
shut the burner off when it detects flame-out during
burner
operation. 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
DANGER!
DO NOT push the reset button
more than once! DO NOT push the reset
button if oil mist is present in the combustion chamber
or when the combustion chamber is hot! DO NOT
operate your furnace if excess oil, oil vapor or fumes
have accumulated in or near your furnace. As with
any oil burning furnace, improper operation may result
in a fire or explosion hazard.
1. Refer to Figure 7A.
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
furnace to cool for at least 30 minutes. DO NOT
push the reset button.
4. When you are sure all mist has been cleared from
the chamber and the combustion chamber is cool,
depress the red button on the primary control for
2 seconds, then release. Reset the control ONCE
ONLY.
5. If the burner will not restart, call your Clean Burn
dealer immediately.
When troubleshooting furnace/burner shutdown situations, Clean Burn recommends the following sequence of
actions:
• Follow the procedure for Resetting the Oil Primary Control provided in this section.
• If the burner will not restart, review the information provided in this section on the functioning of the
Fan Switches and the Hi-Temp Limit Switches.
• If the burner still will not restart, contact your Clean Burn Distributor for immediate service.
Fire and explosion hazard.
