position. If the unit still does not

 

operate, check the heater hi-limit.

check the fuse on the SMART

 

BOARD. If faulty, replace.

If only lights 1 and 2 are lit,

 

check your connections to the

flame detection module. (blue/ black and white/brown wires). If connection is good replace flame detection module.
