Frequently Asked Questions - 315PRV Volcan
How do I light the pilot on the Volcan 315PRV?
Turn the gas control knob to the 'Pilot' position, press it down and hold it, then press the piezo igniter button until the flame appears. Keep the knob pressed for about 30 seconds to allow the thermocouple to heat up, then release it.
What gas pressure is required for the 315PRV?
The heater operates at 20 mbar for natural gas and 28–30 mbar for propane. Check your local gas supply and adjust the pressure regulator accordingly.
How often should I replace the magnesium anode?
Replace the magnesium anode every 1–2 years, depending on water hardness. A worn anode reduces protection against corrosion and may void the tank warranty.
Why is my water heater releasing water from the relief valve?
This is usually a sign of overpressure or an internal temperature build-up. Check the water pressure; if it exceeds 8 bars, install a pressure reducer. The valve may also be defective and need replacement.
How do I adjust the temperature on the thermostat?
Locate the thermostat dial on the front panel. Turn it to the desired temperature, typically between 50°C and 60°C for normal use. The heater will maintain this temperature automatically.
What maintenance is required for optimal performance?
Annually, inspect the gas burner for soot, clean the flue ducts, check the thermocouple, and verify the pressure relief valve by lifting its lever. Drain and descale the tank if water hardness is high.
Can I convert this heater from natural gas to propane?
Yes, the 315PRV can be converted with a conversion kit. Replace the burner injectors and adjust the gas regulator to 28–30 mbar. Always have a qualified technician perform the conversion.
What is the recommended water temperature for energy savings?
Set the thermostat to 55°C as a balance between comfort and efficiency. Keep it above 50°C to prevent bacterial growth. Each year, lower the thermostat by a few degrees before vacations.
My water heater does not produce hot water; what should I check?
First, verify the pilot flame is lit. Then check if the gas supply is open and the thermostat is set correctly. If the pilot stays off, clean or replace the thermocouple. If the burner does not ignite, inspect the gas valve.
Are spare parts available for the Volcan 315PRV?
Yes, common spare parts such as thermocouples, burners, magnesium anodes, and relief valves are available from authorized dealers. Contact Volcan customer service to source genuine parts.
