Check daily to be sure that the immediate area around the boiler or water heater is free and clear of
any combustible materials, including flammable vapors and liquids.
Weekly
Observe the conditions of the main flame. A normal high fire flame is mostly blue, though the refractory
in the rear of the heat exchanger will glow an orange red color. A normal low fire flame is also blue.
The refractory may not show any orange-red color at low fire. Never attempt to adjust the flame "by
eye". The correct flame/combustion is dependent on the air and gas adjustment.
Correct air adjustment is essential to the efficient operation of this appliance. Ensure that the flow of
combustion and ventilation air is not obstructed. If an adjustment in the combustion appears
necessary, the flue gas composition should be checked with a combustion analyzer and compared to
the values stated in the Combustion Setup and Adjustment combustion settings table in 3.11.2. If an
adjustment to the combustion is necessary, call a qualified and knowledgeable installer or service
agency that has been trained on the Patterson-Kelley appliance.
