If the control does not detect flame by the
end of the trial for ignition, the control
performs a 10 second post-purge. On the

does not light after 4 trials, the control will
lockout for 1 hour and then try another set
of 4 trials. On the SHW146 CE the unit will
lockout until manually reset.

integrated pump will continue to run for its
respective pump delay time., and then turn
off
