streams of water flow through the faucets, close them and check all water connections for possible leaks.

4.NEVER OPERATE THE WATER HEATER WITHOUT FIRST BEING CERTAIN THAT IT IS FILLED WITH WATER.

INSTRUCTIONS FOR BOILER CONNECTIONS

The Single-wall Indirect connection labeled “To Boiler Return” should be piped to the boiler return piping as close to the boiler as possible and especially after any flow control or check valves in the space heating return piping. The use of a union and a shut-off valve is recommended. The use of a flow control or check valve is required to prevent back flow through the water heater during operation of the space heating system. Pipe and fittings between the boiler and Single-wall Indirect should be ¾” diameter or larger.

CAUTION

Maximum boiler water supply temperature to the indirect heat exchanger must not exceed 240°F (116°C).

CONNECT WATER BOILER SUPPLY PIPING

1.For a space heating system that utilizes ZONE VALVES, refer to Figure 2. 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.
