Frequently Asked Questions - 641 TQG /HA(BK) Hotpoint Ariston
What type of gas can this hob use?
The 641 TQG /HA(BK) is supplied for natural gas G20 but can be converted to LPG G30/G31 using the included injectors. Always follow the instructions in the manual for safe conversion.
How do I connect the hob to the gas supply?
Connection must be done by a skilled gas installer. The hob features a G1/2" gas inlet on the rear or right side. Use a flexible hose or rigid pipe that complies with local regulations.
How do I replace the injectors to convert from natural gas to LPG?
To convert, remove the burner caps and heads, then use the supplied LPG injectors. Replace the injectors and adjust the bypass screws as described in the manual. Always verify with a leak detection spray.
How do I clean the glass surface?
Clean the tempered glass with a soft cloth and non-abrasive cleaner. Avoid harsh pads or sharp objects. Wipe away spills immediately to prevent staining, especially sugary substances.
What safety features does the hob have?
All burners have flame failure safety valves (thermocouples) that cut off the gas supply if the flame goes out. The automatic ignition also stops when the knob is released.
Why does the flame go out when I release the knob?
This usually means the thermocouple is not heated enough. Keep the knob pressed for 3-5 seconds after ignition. If the problem persists, check that the flame reaches the thermocouple and that the device is clean.
How do I know if the installation is compliant?
Ensure the cut-out dimensions match (560 x 480 mm) and there is proper ventilation in the room. The hob must be installed by a certified professional to meet local safety standards and warranty requirements.
Can I re-ignite during operation?
No, the automatic ignition is designed for manual operation only. To re-light a burner, turn the knob to the off position, wait a few seconds, then rotate to the maximum flame position and press the ignition.
What is the recommended cut-out size?
The recommended cut-out for a built-in installation is 560 x 480 mm. Make sure the cut-out is clean and the edges are sealed with the provided gasket to prevent moisture ingress.
How can I get spare parts?
Spare parts such as injectors, thermocouples, knobs, and burner caps are available through Hotpoint Ariston authorized service centers. Use the model number 641 TQG /HA(BK) when ordering to ensure compatibility.
