32.Rate of flue product movement is controlled by “V” Baffles on the heat exchanger to maximize heat transfer.

33.Heated products of combustion then pass over the Secondary Heat Exchanger to absorb additional heat.

34.Flue products pass into the flue collector and are exhausted from the unit.

End of Sequence

35.Set Point temperature is satisfied.

36.Power to the gas valves is turned off.

37.Combustion Air Blower ramps up to 100% speed and runs for a 30 second post purge timing and turns off.

38.Excel 10 is now in a standby mode waiting for the next “Call for Heat”.

MAINTENANCE

FIG. 76 Flame Pattern

Listed below are items that must be checked to ensure safe reliable operations. Verify proper operation after servicing.

CAUTION￿

Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and dangerous operation.

A.EXAMINE THE VENTING SYSTEM at least once a year. Check more often in the first year to determine inspection interval. Check all joints and pipe connections for tightness, corrosion or deterioration. Flush the condensate drain hose with water to clean. Clean screens in the venting air intake system as required. Have the entire system, including the venting system, periodically inspected by a qualified service agency.

B.VISUALLY CHECK MAIN BURNER FLAMES at each start up after long shutdown periods or at least every six months. A burner viewport is located on the burner mounting flange.

WARNING￿

The area around the burner viewport is hot and direct contact could result in burns.

1.Normal Flame: A normal flame at 100% of burner input is blue, with slight yellow tips a well defined flame and no flame lifting.

2.Yellow Tip: Yellow tipping can be caused by blockage or partial obstruction of air flow to the burner.

3. Yellow Flames: Yellow flames can be caused by blockage of primary air flow to the burner or excessive gas input. This condition MUST be corrected immediately.

4.Lifting Flames: Lifting flames can be caused by over firing the burner, excessive primary air or high draft.

If improper flame is observed, examine the venting system, ensure proper gas supply and adequate supply of combustion and ventilation air.

C. FLUE GAS PASSAGEWAYS CLEANING

PROCEDURES:

Any sign of soot around the inner jacket, outer jacket, flue pipe connections, burner or in the areas between the fins on the copper heat exchanger indicates a need for cleaning. The following cleaning procedure must only be performed by a qualified serviceman or installer. Proper service is required to maintain safe operation. Properly installed and adjusted units seldom need flue cleaning.
