Connect boiler to system as shown in Figure 7 when

 

DHW piping

 

 

 

zone valve zoning. The primary/secondary piping

 

 

 

shown ensures the boiler loop will have sufficient

 

 

 

flow. It also avoids applying the high head of the

 

 

 

boiler circulator to the zone valves.

 

 

2.

When using a closed-type expansion tank, connect

 

 

 

the expansion tank and make-up water piping as

 

 

 

shown in Figure 4, page 13.

 

 

3.

Connect DHW (domestic hot water) piping to indirect

 

 

 

storage water heater as shown.

 

 

 

 

The

space heating during DHW 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 DHW heating.

4.Controlling the system circulator

a.To cycle the system circulator from the Ultra PhD control module, add a circulator relay wired to the boiler circulator terminals as shown in the Ultra Control Supplement.

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 -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.
