on the auto reset safety PCB six pin plug.
The following results should be obtained:

Violet – blue wire: 24 Volts AC.

Component Adjustment Procedures

Burner Pressure Adjustment:
Check the inlet gas pressure at the gas valve inlet test point before adjusting
the gas valve burner pressure regulator.
Adjust the burner gas pressure to match the appliance rating plate as follows:
1. Remove the Lower In/Out Header Panel, Gas
Valve Cover and Gas Valve Enclosure.
2. Remove the Gas Valve burner pressure
adjustment screw cap by unscrewing in an
anticlockwise direction.
3. Using a screwdriver, turn the inner adjustment
screw clockwise to increase or counter-
clockwise to reduce gas pressure to the burner.
4. Replace the burner pressure adjustment screw cap and tighten firmly to prevent gas
leakage.
5. Replace the Gas Valve Enclosure, Gas Valve Cover and Lower In/Out Header Panel.
If the desired burner pressure cannot be achieved by adjusting the burner pressure
regulator, check the gas supply pressure to the pool heater using a manometer at the inlet
test point on the gas valve. If the inlet pressure is not within the prescribed limits, take the
necessary steps to provide the correct gas pressure to the heater. If the inlet pressure is
within the prescribed limits replace the gas valve.
