CHEDULE
Label all wires prior to disconnection when servicing controls. Wiring errors can
cause improper and dangerous operation.
Verify proper operation after servicing.
5.1.1 Daily
Observe operating temperature and general conditions. Make sure that the flow of combustion and ventilating air
to the boiler is not obstructed. Determine the cause of any illuminated red indicators, unusual noises or operating
conditions and make the necessary corrections.
Check daily to be sure that the boiler area is free and clear of any combusti-
ble materials, including flammable vapors and liquids.
5.1.2 Weekly
Observe the conditions of the main flame. A normal high fire flame shows an orange screen with a blue halo. In
Low fire the burner should display a reddish orange glow. However, do not attempt to adjust the flame “by eye”.
Correct air adjustment is essential for the efficient operation of this boiler. If an adjustment to the combustion is
necessary, the flue gas composition should be checked with a carbon dioxide (CO
2
) or oxygen (O
2
) analyzer to
set conditions. Refer to Section 3.12.
