SERVICE PROCEDURES AND ADJUSTMENTS

WARNING: CERTAIN PROCEDURES IN THIS SECTION REQUIRE ELECTRICAL TEST OR MEASURE- MENTS WHILE POWER IS APPLIED TO THE MACHINE. EXERCISE EXTREME CAUTION AT ALL TIMES. IF TEST POINTS ARE NOT EASILY ACCESSIBLE, DISCONNECT POWER AND FOLLOW LOCKOUT / TAGOUT PROCEDURES, ATTACH TEST EQUIPMENT AND REAPPLY POWER TO TEST.

BLOWER AIR PRESSURE

ADJUSTMENT

AIR PRESSURE SWITCH

ADJUSTMENT

Adjust the blower air pressure at the gas combination manifold pressure tap. Turn the gas valve off. Remove pipe plug from pressure tap on the outlet side of the gas combination valve and install a gas manometer. The air pressure should be 0.35"W.C. (0.09 kPa) to 0.4"W.C. (1 kPa). If the reading is not correct adjust blower speed control adjustment screw clockwise to increase and counter-clockwise to decrease.

Blower air pressure adjustment must be performed before proceeding with this procedure.

The air pressure switch senses the pressure level produced by the blower for combustion. When the pressure is sufficient, the switch closes and supplies power to the ignition control module. The gas ignition sequence starts to light the gas pilot and then main burner. If gas pilot is not lighting (valve not energized), the ignition control module may not be receiving power, assuming the minimum water level is satisfied. Check the air pressure switch operation then adjust if necessary as outlined in the procedure below.

1.Turn the power switch off.

2.Remove the front panel from the cabinet base.

A.Inspect the air intake to the blower for debris build up and clogging.

1)If debris is found, clean it away from the air intake.

B.Turn the power switch on and verify main burner ignition.

1)If burner ignites no adjustment to the pressure switch setting is necessary.

2)If burner does not ignite, proceed to step 3.

3.Turn the main gas valve to off.

4.Adjust the air pressure switch setting as follows:

A.Turn the adjustment screw fully clockwise to the highest setting.

B.Slowly turn the adjustment screw counter- clockwise until main gas valve energizes then add 1/2 turn to the adjustment.
