Installation (Water Supply Lines)
Install the service valve at the Cold water inlet port to the heater. This valve is used when servicing and draining the
unit – see Figure 10.
The water piping supplying the heater should be the same nominal size as the water heater fittings on the unit.
Before connecting the service valve to water heater, run water through the supply pipe to purge sand, debris, air,
caulking, etc – see Figure 11.
Position a bucket at the water outlet of the heater and open the service valve. Allow the cold water flow through the
water heater for approximately 15 seconds and close the service valve – see Figure 12.
