SECTION C: Installation

To complete the installation of the pool heater, the pool thermostat needs to be installed in the main return wa- ter line, upstream of the heater. This will ensure that the heater will be energized at the right time.

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 and a system supply water temperature below 140°F. When starting with a cold pool, make initial adjustments. Make final adjustments when pool water approaches desired temperature.

The use of a bypass is required for proper operation in a pool heating application. Use the following instruc- tions to set the manual bypass:

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 ½ open position, and Valve B to fully open position.

4.Adjust Valve A until the inlet water temperature is 120°F. 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 and Valve A is fully open, then slowly throttle Valve B closed to increase the inlet water temperature to 120°F.

Automatic Chlorinators and Chemical Feeders

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

All chemicals must be introduced and completely di- luted into the pool or spa water before being circulated through the heater. Do not place chlorine tablets or bromine sticks in the skimmer. High chemical concen- trations will result when the pump is not running (e.g. overnight).

Chlorinators must feed downstream of the heater and have an anti-siphoning device to prevent chemical back-up into the heater when the pump is shut off.

NOTICE: High chemical concentrates from feeders and chlorinators that are out of adjustment will cause very rapid corrosion of the heat exchanger in the heater. Such damage is not covered under the warranty.

Winterizing Your Heater

Heaters installed outdoors as pool heaters in freezing climate areas should be shut down for the winter. To shut 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.
