Daily
Observe operating temperature and general conditions. Make sure that the flow of combustion and
intake air to the appliance is not obstructed. Determine the cause of any service codes or lockouts on
the NURO
®
touchscreen display. Observe any unusual noises or operating conditions and make the
necessary corrections. Notify responsible individuals for required corrective action or repair.
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
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.
