5.Check system for leaks. Repair as necessary.

F. Connect water boiler return piping (See Figures 3 thru 6).

(For connection to a steam boiler skip ahead to H on page 12).

1.Determine where in the boiler and space heating piping system the Alliance™ connections should be made by identifying the type of system from Figures 3 thru 6.

2.In all cases, the Alliance™ connection labeled "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.
