5 Your roll out switches will be located around the burners. Hence flames roll out limit. These are usually manual reset do to the safety factor. So they will be size of a quarter on older models now days bout size of a dime. Two wire 1 in 1out 24v. W/t a button for manual reset. Now if one has been tripped after starting unit back up need to watch and cycle unit numerous times to see why u had this failure.
