Combined space heating/water heating applications

1.Figure 14 shows recommended piping between Gas boiler and PLUS water heater. All show direct connection of the water heater piping to the boiler because the boiler circulator shuts down during water heater operation.

2.Table 3, page 29, uses the recommended flow rates for the PLUS water heater and minimum flow rates for the Gas boiler to provide recommended water heater piping and circulator sizing. If using another circulator, verify it is at least equal to the Taco selection given in Table 3, page 29. For general information on head loss through boiler and

boiler-to-water heater piping, refer to the Gas Boiler Manual.

3.Procedure:

Step 1: Select Gas Boiler model and water heater model in Table 3, page 29.

Step 2: Read recommended minimum flow rate, GPM, in table.

Step 3: Read across to find recommended minimum pipe size for boiler-to-water heater piping.

Step 4: Read across to find recommended Taco circulator model. Use a circulator with a pump curve at least equal to the Taco circulator shown. See Figure 16, page 29 for pump curves of typical Taco circulators.

Dedicated water heating-only applications

1.Figure 15 shows recommended piping between Gas Boiler and PLUS water heater for dedicated water-heating only applications.

2.Pipe sizing:

Table 4, page 29, provides the recommended minimum pipe size for boiler-to-water heater piping.

3.Circulator:

Use the circulator recommended in Table 4, page 29. Install the circulator as shown in Figure 15.

4.Procedure:

Step 1: Select Gas Boiler model and water heater model in Table 4, page 29.

Step 2: Read flow rate expected using the circulator speci- fied inthe last column.

Step 3: Size connecting piping as listed under “Boiler pip- ing” in the table.
