Installation

The heating mode may be one of the following options:

1.A fan coil/air handler (Figure 14).

2.A hydronic baseboard (finned tube) loop (Figure 15).

3.A hydronic in-floor heating loop (Figure 16).

The following is a list of requirements for the installation of the heating loop to the water heater.

1.Install shut-off valves and unions so that the water heater can be isolated from the heating module should servicing of the water heater become necessary.

2.Install a drain valve at the lowest point of the heating loop so that water can be drained from the heating mod- ule without affecting the water heater.

3.If the air handler does not have a venting means at the highest point of the piping arrangement, install an air bleed at the highest point of the plumbing arrangement.

4.If solenoid valves are used for zone heating applica- tions, they must include electrical proof of valve full open position and must be connected to the water pump.
