2. For a space heating system that utilizes CIRCULATORS, refer
to Figure 3. The Single-wall Indirect connection labeled
“FROM BOILER SUPPLY” should be piped to the boiler
supply piping. Mount the circulator making sure the flow arrow
points toward the water heater. The use of shut-off valves and
unions are recommended for future service convenience. The
use of an air separator and vent is recommended to eliminate air
in the system. Pipe and fittings between the boiler and Single-
wall Indirect must be ¾” diameter or larger.
