Primary Piping

SECTION V - Primary Piping

General Piping Requirements

Low Water Cutoff Device

-The ELITE is equipped with a factory installed pressure switch style Low Water Cut Off device.

-The minimum operating system pressure allowable with this device is 10 psig.

-Check local codes which require a low water cutoff device for compliance of this device.

Backflow Preventer

-Use a backflow preventer valve in the make-up water supply to the unit as required by local codes.

Primary System Piping Applications

BEST PRACTICE

All piping applications shown in this instal- lation manual utilize a primary/ secondary piping arrangement. This method is rec- ommended as a means to provide priority to the production of domestic hot water. For other piping arrangements, consult the Engineering Department at Triangle Tube or consult other approved/recognized design arrangements.

BEST PRACTICE

On piping applications utilizing a single zone or other recognized piping design arrangements it is recommended the installer uses flow/check valves with weighted seats at or near the appliance to prevent gravity circulation.

Expansion Tank and Makeup Water

Ensure the expansion tank is properly sized for the outer tank volume (22 gallons) and the system volume and temperature.

CAUTION

Undersized expansion tanks will cause sys- tem water to be lost through the pressure relief valve and cause additional makeup water to be added to the system. Eventual primary tank failure can result due to this excessive makeup water addition.

The expansion tank must be located as shown in Fig. 7, 7A or 7B page 20 or as per recognized design methods. Refer to the expansion tank manufacturer instructions for additional installation details.

Connect the expansion tank to an air sepa- rator only if the air separator is located on the suction side (inlet) of the system circu- lator. Always locate and install the system fill connection at the same location as the expansion tank connection to the system.

Diaphragm (Bladder) Expansion Tank

Always install an automatic air vent on the top of the air separator to remove residual air from the system.

Closed-Type (Standard) Expansion Tank

It is recommended to pitch any horizontal piping toward the expansion tank 1 inch per 5 feet of piping. Use 3/4” piping for the expansion tank to allow air within the sys- tem to rise.

For proper operation of the expansion tank and system, remove the factory installed automatic air vent from the ELITE and plug the connection. (See Item 10, Fig. 28 page 50)
