GSW 5065 manual Installation

Installation

The heating mode may be one of the following options:

A.A fan coil/air handler (Figure 28).

B.A hydronic baseboard (finned tube) loop/In floor heating (Figure 29).

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.
