SUPPLY TO L1 & L2
1.Use a Microampere (µamp) meter to measure the flame current on both wires S1 & S2.
2.Connect a Microampere meter as shown above to S1 & S2, to read the actual flame current of each igniter.
3.The ignition system is 1 µamp sensitive.
4.You should be able to attain a reading of 4 µamps when connected as shown.
5.The meter is to be placed in series with the flame sense wires S1 & S2.
6.Connect at the board or the igniter end,
whichever is more convenient.
BLOWER ADJUSTMENT
Disconnect the electrical power to the machine and follow lockout / tagout procedures.
1.Remove the blower motor and mounting assembly as outlined under Blower and Motor in Removal and Replacement of Parts.
2.Loosen the motor mounting bolts.
3.Adjust the motor position until the blower is parallel to and 1/4" inch away from the motor mounting plate. Check to see if the blower is square to the motor mounting plate at the top, bottom, left and right of the blower.
A.If the blower is square, then tighten motor mounting bolts and proceed to step 4.
B.If the blower is not square, continue adjusting until proper spacing is achieved then tighten motor mounting bolts. If necessary, place shims between motor and frame.
