FOGATTI InstaShower Series RV Tankless Water Heater Instruction Manual

FOGATTI InstaShower Series RV Tankless Water Heater

Function Introduction and Explanation

The water heater is designed with an intelligent control system. Simply set the temperature and press the start button for the machine to detect the qualified water flow. After ignition, the gas valve invites propane to ignite the burner, then runs steady hot water. The intelligent device detects the entire process, where may shut down gas whenever abnormal failures are detected.

The water heater is forced exhaust structured. The outside air passing through the air intake grille enters the combustion chamber via an anti-dust net. Flue gas or air mixture is discharged outdoors through the small-diameter pipe automatically and safely.

1. Digital constant temperature system: A microcomputer control system, which constitutes the “computer” of the whole machine, controls the water, and electricity of the water heater in a coordinated manner, and does not cause the temperature of the water temperature to fluctuate, satisfying the user’s comfort.
2. Low startup water pressure: Low startup water pressure makes it easier to use.
3. Flameout protection: When the water heater accidentally flames out during operation, the gas supply will be automatically cut off to ensure no leakage.
4. Speed changing and wind resistance function: When a blockage of the flue or the smoke is blocked, the built-in microcomputer system will increase the operating speed of the fan and eliminate the generation of harmful gases. When the speed reaches the predetermined maximum speed, the microcomputer system will issue the cease-gas and cease-fire instructions, effectively guaranteeing safety.
5. Water and gas linkage control: When the water supply is interrupted or the water outlet valve is closed, the water heater will automatically stop the combustion and shut down.
6. Outlet water temperature display: Enables outlet water temperature display function.
7. Antifreeze function: Antifreeze function: When the water pipe temperature is lower than 43°F±2°F 6±1° and the wired controller displays the “Fd” character, the machine starts the ignition and runs a certain load of water for 2 to 5 seconds until the water temperature reaches 90°F±2°F 32±1°. Around 3 minutes, the machine starts self-testing again. When the temperature is lower to 43°F±2°F(6±1°C) again or the antifreeze thermostat control stops working, the water heater starts again with the same cycle.
   • In the process of starting the antifreeze function, if a fault occurs, the corresponding fault is reported, and the corresponding code is displayed. After 1 S minutes, the system automatically clears the fault code.
   • If the antifreeze start condition is fulfilled, the antifreeze will automatically start again, and the cycle continues.
8. Error auto-diagnosis and error code display function: Intelligent microcomputer can monitor various safety devices, gas proportional valves, and other components in real-time, find faults, and timely safety shutdown. Advanced fault code display function makes it easy to use and maintain.
