Plumbing - 9100 Series

THIS PROCEDURE MUST BE PERFORMED BY A QUALIFIED TECHNICIAN.

CAUTION

FREEZE PROTECTION: Risk of property damage. Hydronic heating system freeze-ups WILL cause extensive damage to the entire heating system and/or property. It is the responsibility of the installer to provide protection against freezing.

PIPING SUPPORT: Risk of equipment damage or personal injury. DO NOT use the exchanger as support for piping. Support brackets should be in place to ensure proper operation of the system and to keep pressure off the inlet and outlet piping.

The ThermElect Hydronic system should be plumbed with a primary loop and secondary (zone) loops. The primary loop needs to consist of a minimum of 12’ of 1.25” pipe. The heat exchanger inlet and outlet are 1.5” diameter, reducers will be required if 1.25” pipe is selected for the primary loop. The secondary (zone) loops require additional pump(s) to operate effectively. Refer to Typical Primary Loop and the Typical System Plumbing Diagrams below for installation information.

The primary loop serves to regulate heat transfer from the system’s heat exchanger. The primary loop pump should be powered by ThermElect Hydronic control system as shown here. If using another control method, flow MUST continue for at least 30 seconds at the end of a heat call.

FIGURE 13 TYPICAL PRIMARY LOOP

NOTE: There are many additional ways to connect plumbing and regulate temperature from the primary loop onward.

NOTE: Check valves on the return side are recommended to prevent back flow into the SYSTEM.

Balancing valves are recommended to provide an even flow of water between all systems.

Flow must continue for a minimum of 30 seconds after call for heat ends.
