How the MasterTemp Pool Heater Works

1. Heating Process & Core Components

• Gas Combustion System: Utilizes natural gas or propane in a sealed combustion chamber

• Cupro-Nickel Heat Exchanger: Features a vertical tube design for maximum heat transfer efficiency

• Electronic Ignition System: Energy-saving hot surface ignition (no standing pilot light)

• Microprocessor Control: Precisely regulates water temperature (±1°F accuracy)

2. Step-by-Step Operation

• Water enters through the inlet and passes through the filter system

• Flow switch activates when sufficient water flow is detected

• Control board initiates the heating sequence

• Gas valve opens and hot surface igniter activates

• Combustion occurs in the sealed chamber

• Water circulates through the vertical heat exchanger tubes

• Heated water returns to the pool at the set temperature

3. Advanced Control Systems

• Thermal Regulation: Automatically adjusts gas valve operation

• Self-Diagnostic Capabilities: Continuously monitors system status

• Freeze Protection: Activates when ambient temperature drops below 45°F
