NOTE: For automatic temperature adjustment, a Cold Water Run (CWR) system can be used instead of a manual bypass. See Fig. 10.

CAUTION: Combusti on air must not be contaminated by corrosive chemical fumes which can damage the heater and void the warranty.

Winterizing Your Heater

Heaters installed outdoors as pool heaters in freezing climate areas should be shut down for the winter. To shut the down heater, turn off manual main gas valve and main gas shut-off. Close isolation valves. Drain the heater using the hose bibs located on the bottom of the heat exchanger.

NOTE: There are 2 separate drains on the MVB that must BOTH be drained to protect the heat exchanger. These are both accessible by removing the lower front door from the heater. Drain any piping of all water that may experience below- freezing temperatures.

Pool/Spa Water Chemistry

CAUTION: Corrosive water voids all warranties.

NOTE: Chemical imbalance can cause severe damage to your heater and associated equipment.

Chemical imbalance can cause severe damage to the pool heater and associated equipment. Maintain the water chemistry according to the chart below. If the mineral content and dissolved solids in the water become too high, scale forms inside the heat exchang- er tubes, reducing heater efficiency and damaging the heater. If the pH drops below 7.2, this will cause cor- rosion of the heat exchanger and severely damage the heater. Heat exchanger damage resulting from chem- ical imbalance is not covered by the warranty.

For your health and the protection of your pool equip- ment, it is essential that your water be chemically balanced. The following levels must be used as a guide for balanced water.

Occasional chemical shock dosing of the pool or spa should not damage the heater providing the water is balanced.

Automatic chemical dosing devices and salt chlorina- tors are usually more efficient in heater water, unless controlled, they can lead to excessive chlorine level which can damage your heater.
