FAULTS / SOLUTIONS

Below is a list of some of the causes and possible solutions to a series of problems that might be encountered
and could cause a failure to start or irregular burner operation.
A fault usually makes the lock-out lamp light which is situated inside the reset button of the control box (3, fig.
1, page 2).
When lock out lamp lights the burner will attempt to light only after pushing the reset button. After this if the
burner functions correctly, the lock-out can be attributed to a temporary fault.
However, if lockout continues, you must determine the cause of the problem and take the action illustrated in the
solution column in the tables below.
