cycle to help remove air from boiler water.

Low system water pressure.

Check boiler water pressure, adjust feedwater as

required.

Rough ignitions

Gas pressure problem.

Refer to Table 3-5 for required pressure range.

Dirty/damaged burner.

Refer to Section 17 Service and maintenance for

proper procedure to check burner. Replace if

necessary.

Dirty/damaged ignitor/flame sensor.

Refer to Section 17 Service and Maintenance for

proper procedure to check ignitor/flame sensor.
