INSTALLATION Continued Circulator Pump R equir ements This is a low mass, high efficiency hot water boiler which must have adequate flow for quiet, efficient operation. Pump selection is critical to achieve proper operation. A pump should be selected to achieve proper system design water temperature rise.
The installer must ensure that the boiler has adequate flow without excessive temperature rise. Low system flow can result in overheating of the boiler water which can cause short burner ON cycles, system noise and in extreme cases, a knocking flash to steam.
INSTALLATION Continued Sludge formed as the result of excessive oxygen in the system can restrict water flow resulting in a premature boiler failure. Any boiler damage due to excessive oxygenation is non- warrantable.
Boiler Flow Ra te CA UTION : The maximum flow rate for models 495,000 - 745,000 Btu/hr is 60 GPM and 90 GPM on 985,000 - 2,065,000 models. Do not exceed the maximum flow rate of the heating boiler . If higher flow rates are required through the boiler , an optional Cupro-Nickel heat exchanger is available.
INSTALLATION Continued 8. Recheck all air vents as described in step 4. 9 . Inspect the liquid level in the expansion tank. The system must be full and under normal operating pressure to ensure proper water level in the expansion tank. Ensure that diaphragm type expansion tanks are properly charged and not water logged.
