check whether ball valve is jammed, check ball
valve throughway to see if foreign objects are
preventing it from closing
check cables and flame return gate
check flame return gate, check cables, check
connectors
close cover
replace end-switch
connect sensor at input
measure sensor (approx. 2k at 25° C) replace if
required
replace sensor
sensor temperature above measuring range
(1100° C)
measure sensor (approx. 2k at 25° C) replace if
required
replace sensor
sensor temperature below measuring range (-
10° C)
connect sensor at input
measure sensor (approx. 2k at 25° C) replace if
required
