Do you have a question about the Hotpoint Ariston TQG 641/HAEE and is the answer not in the manual?
This document describes the Hotpoint Ariston TQG 641 /HA(BK) EE and TQG 641 /HA(WH) EE gas hob models.
The Hotpoint Ariston gas hob is designed for domestic use, specifically for cooking food. It features multiple gas burners of varying sizes and power outputs, allowing for versatile cooking options. Each burner is controlled by a dedicated knob, which also incorporates an ignition function for automatic lighting. A key safety feature is the safety device (thermocouple) that automatically cuts off the gas supply if the flame is accidentally extinguished.
The hob is a Class 3 built-in appliance.

Electrical Specifications:
The appliance is designed to operate with alternating current at the voltage and frequency indicated on the data plate. It is equipped with a three-pole power supply cable with a green and yellow earth wire.
Installation Dimensions:
Ventilation Requirements:
Gas Burners: Each burner can be set to Off (0), Maximum, or Minimum flame settings using its control knob.
Ignition: To light a burner, press down and turn the corresponding knob anti-clockwise to the maximum setting while holding a lit match or lighter near the burner. For models with integrated ignition, simply press the knob all the way in and turn it anti-clockwise to "High" until the burner lights. The knob must be held for 2-3 seconds to allow the safety device to heat up and keep the flame lit. If the flame extinguishes, turn off the knob and wait at least 1 minute before relighting.
Optimal Cookware Usage:
Cookware Diameter Recommendations:
| Burner Type | Ø Cookware Diameter (cm) |
|---|---|
| Rapid (R) | 24-26 |
| Semi Rapid (S) | 16-20 |
| Auxiliary (A) | 10-14 |
Stability: Ensure pan supports are correctly fitted and pans are centered over the burner. Pan handles should align with a support bar and not protrude beyond the hob's front edge for maximum stability.
Gas Type Adaptation: The hob can be adapted to different gas types by replacing burner nozzles and adjusting the minimum flame setting. This procedure involves:
Switching Off: Always disconnect the appliance from the electricity supply before any cleaning or maintenance.
Cleaning the Hob Surface:
Cleaning Hob Parts:
Gas Tap Maintenance: If taps become jammed or difficult to turn, they must be replaced by a qualified technician.
