WINTERIZING THE POOL & SPA HEATER

Heaters installed outdoors in freezing climate areas are subject to be shut down for the winter. Observe the following procedure for winterizing the heater:

1.Turn off gas valve, manual gas valve, and electrical supply to the heater.

2.Open drain plug located on the inlet/outlet header, (under water pipes). Remove the heat exchanger inspection panel on the side opposite water piping to gain access to the drain plug on the return header. Open drain plug on return header.
