The overflow connection should be piped to an approved drain for gravity flow of any water that may reach that level in the tank. The purpose of the overflow connection is to keep the tank from being flooded in case a high level condition occurs in the unit. If a feed system is used in proper operation, the overflow should not need a trap or any valve for proper discharge of the water into an atmospheric drain.

HFS/HTS:

The pump(s) suction piping should already be installed on the feed system from the factory. This would include a gate valve and strainer for each pump and unions installed in order to remove or replace the pump if necessary. Pump bypass connections are also located on the bottom of the tank. These connections are used (when necessary) in conjunction with the pump discharge in order to bypass flow back to the tank when the pump GPM flow exceeds the flow required by the boiler. These connections are typically used to help keep the flow rate on the operating curve of the pump and to help introduce water into the boiler at a more reasonable rate. However, these connections may not be necessary depending on the system design. A stop valve and check valve should always be installed as close to the boiler inlet as possible.

CFS:

The pump is a tank mounted pump mounted directly on the top of the tank. The pump wetted parts are submerged in the tank with suction no less than 2” from the bottom of the tank. The pump suction has a screen to protect the pump from debris. This screen will need cleaned periodically for proper pump operation. A throttling valve may be required in the pump discharge piping to keep the pump on its operating curve. A stop and check valve should always be installed as close to the boiler inlet as possible.

All electrical connections must conform to the NEC and to all other applicable State and Local Codes. Wiring to the main power terminals in the control panel (if supplied) by the contractor must have current carrying capacity equal to at least 125% of the amperage rating of the boiler feed system. Pump motors supplied are multi-tapped motors and the wiring in the motors should be checked to make sure it matches the voltage being supplied. If wiring was done at the factory, the wiring diagram will be supplied with the boiler feed system. The power supply voltage must be as shown on the wiring diagram enclosed.

Caution:

All control panels and controls are subject to some internal heat. Adequate boiler room ventilation must be provided.
