If a pilot extinction occurs within 10 seconds of turning the hot tap off, it is possible that the pressure switch is

out of adjustment, if the pressure switch remains in the high flow position in excess of 10 seconds after the fan
switches to low speed interruption of the current to the thermoelectric valve occurs.
It is possible to adjust the pressure switch to ensure a rapid return from high to low flow.
