90 GPM

 

 

If higher flow rates are required through the water heater, an optional Cupro-Nickel heat exchanger is available. Consult the factory for specific application requirements.

The heat exchanger is capable of operating within the design flow rates required for the water heater, storage tank(s) and connecting piping. Erosion of the finned copper tubes may occur if the flow rate exceeds the maximum allowable flow rate through the water heater. The maximum flow through the water heater must be adjusted with the bypass valve in the full closed position. Maximum flow is 90 GPM. Flow rate can be determined by measuring the temperature rise through the water heater when it is firing at full rate input. Also see Bypass Initial Setup of Maximum Water Flow for adjustment procedure.

Setting temperature rise on an Intelli-Finwith an automatic bypass is accomplished by disconnecting the power leads to the actuator, (multi-pin connector on rear of appliance), declutching the actuator drive and manually closing the bypass valve. Manual adjustment of the bypass must not be attempted if the 24 VAC power leads are connected to the terminals on the appliance, the appliance is operating or if there is any torque on the bypass valve by the actuator. Disconnect the 24 VAC power leads to the bypass valve actuator. The declutch button on the actuator must be pushed down and held in the depressed position to disengage the gear driven motor that operates the valve. The declutch button must push in easily without forcing its movement. If the button does not easily move when pushed, the valve is under torque. Forcing the declutch button in will cause non-warrantable damage to the actuator. Torque can be removed by disconnecting the power leads to the valve actuator. With the declutch button fully depressed, move the actuator handle till it is perpendicular to the piping. This fully closes the bypass valve. The position of the handle is the same as the position of the butterfly in the valve seat. With the bypass fully closed, all inlet water flows through the secondary heat ex- changer and then through the primary heat exchanger. No water will flow through the bypass at this time. Turn the appliance on and allow the burner to come on and fire at full rate (100% of input as shown on the Command Display). Adjust the field-installed ball valve in the outlet piping from the water heater to the storage tank to achieve the proper temperature rise for your specific model. Adjustment to achieve this temperature rise ensures a maximum of 90 GPM to the bypass and pump when in operation.

NOTE:

The Excel 10 controller makes all internal calculations in °C and converts the displayed temperature to °F. This may limit exact temperature adjustment. Setting of temperature rise to the nearest °F is acceptable when setting maximum flow.

1.The pump must run continuously when the burner is firing.

2.With the pump running and the burner in the water heater or hot water supply boiler in the off cycle, the Return/Inlet Temp and Supply/Outlet Temp readings on the Command Display should read approximately the same temperatures. Temp Rise in the Command Display should read zero.

3.Turn the water heater or hot water supply boiler on and allow time for the temperature to stabilize. Check the temperature rise in the Command Display when the burner is firing at 100% of rated input.

4.Compare the temperature rise on the Command Display with the required temperature rise. Should adjustment be needed, proceed as follows:

If the temperature rise is too high, the water velocity is too low. Adjust as follows:

1.Check for restrictions in the outlet of the water heater or hot water supply boiler.

2.Check diameter and equivalent length of the piping between the storage tank and water heater.

3.Be sure all valves are open between the water heater or hot water supply boiler and the storage tank. Ensure that all ball valves are fully ported.

4.Check the pump to be sure it is running properly and that the pump motor is running in the proper direction.
