The MVB must be equipped with a field-supplied ex- ternal pump and bypass arrangement. This arrangement blends outlet water with the inlet water to increase the inlet water temperature to a minimum of 120°F (49°C), thereby reducing the likelihood of con- densation forming on the heat exchanger. The pump also serves to circulate water through the heater from the main system piping.

CAUTION: Power to the heater should be interlocked with the main system pump to make sure the heater does not fire without the main system pump in operation. Improper flow control can damage the heater. Uncontrolled flow (too high) or restricted flow (too low) can seriously damage the heater. Follow these instructions to make sure your heater is properly installed.

To complete the installation of the pool heater, the pool thermostat must be installed in the main return water line, upstream of the heater. This will ensure that the heater will be energized at the right time.

1.Turn on pump.

2.Turn on heater and wait until heater goes to full fire.

3.With the heater operating at 100% firing rate, set Valve A (the bypass) to 1⁄2 open position, and Valve B to fully open position. See Fig. 16.

4.Adjust Valve A until the inlet water temperature is 120°F (49°C).

NOTE: Opening the valve will increase the temperature and closing the valve will decrease the temperature.

5.If this process does not raise the inlet water tem- perature to 120°F (49°C) and Valve A is fully open, then slowly throttle Valve B closed to increase the inlet water temperature to 120°F (49°C).

Adjustment of the manual bypass valve is critical to

 

proper operation of the heater. The manual bypass

 

valve should be adjusted to achieve a minimum inlet

 

water temperature of 120°F (49°C) and a system sup-

 

ply water temperature below 140°F (60°C). When

 

starting with a cold pool, make initial adjustments.
