HOT WATER SUPPLY BOILER

This section applies only to those appliance used to supply domestic hot water, installed with a storage tank(s). The integral circulating pump installed in the bypass piping assembly is used to control water velocity through the appliance. Proper water velocity is important for correct operation of your water heater or hot water supply boiler.

FIG. 83 Typical Water Heater Piping with Storage Tank

This section contains specific instructions for those appliances used to supply domestic hot water. All warnings, cautions, notes and instructions in the general installation and service sections apply to these instructions. Hot water supply boilers and water heaters are designed for installation with a storage tank. The operation of the integral circulating pump, properly sizing of the piping between the tank and heater and the control of water velocity, as explained below, are important for correct operation of your water heater or hot water supply boiler.

WATER VELOCITY CONTROL

IMPORTANT

Excessive lime/scale build-up in the heat exchanger tubes is a result of restricted flow and too little velocity in the tubes. Excessive pitting or erosion in the tube is caused by high water flow and too much velocity through the tubes. Care should be taken to measure temperature rise and maintain a velocity as follows:

BYPASS - Initial Set-up of Maximum Water Flow

On initial start-up of the Intelli-Fin the maximum water flow through the two internal heat exchangers must be manually set before the automatic operation of the bypass begins.

CAUTION￿

To ensure proper velocity through the heat exchangers, it is necessary to regulate the temperature rise across the heat exchanger from inlet to outlet. This must be done on initial installation and periodically rechecked. With the correct temperature rise across the heat exchangers when the water heater is firing at 100% of rated input, you may be assured of the proper velocity in the tubes. This will yield long life and economical operation from your water heater or hot water supply boiler.

The maximum flow rate through an Intelli-Fin water heater with a copper heat exchanger must be set to provide and not exceed 90 GPM.
