1.

Connect boiler to system as shown in Figure 3

when circulator zoning. The boiler circulator

 

 

cannot be used for a zone. It must supply only the

 

 

boiler loop.

 

 

2.

Install a separate circulator for each zone.

 

3.

When using a closed-type expansion tank, connect

 

 

the expansion tank and make-up water piping as

 

 

shown in Figure 1, page 3.

 

4.

Connect water heater (domestic hot water) piping

 

 

to indirect storage water heater as shown.

 

 

 

The

space heating during water heater heating. The boiler circulator will turn off, preventing hot water from circulating to the system. The flow/check valve shown on the boiler outlet piping prevents gravity circulation in the boiler loop during water heater heating.

NOTE 1: To ensure adequate flow rate through the boiler, use the following pipe size on all boiler loop piping (connecting boiler to and from the primary/secondary connection, item 21):

Ultra-80 or Ultra-105 – 1" or larger. Ultra-155 or Ultra-230 – 1¼" or larger. Ultra-310 – 1½" or larger.

Use at least the minimum piping size above and pipe the boiler using only primary/ secondary piping as shown. Failure to follow these guidelines could result in system problems.
