Onyx Manuals & User Guides

Оникс is a premier British brand dedicated to the design and manufacture of high-end heating appliances. Part of the Stovax Heating Group, Onyx delivers a distinguished range of luxury gas and electric fires, including the popular Аванти и Слияние ряд.

Known for their "electric evolution" in home heating, Onyx products combine cutting-edge technology—such as app-controlled flame visuals, authentic log effects, and atmospheric mood lighting—with sleek, contemporary styling tailored for modern living spaces. The brand provides extensive support for installation, maintenance, and troubleshooting, ensuring a seamless experience for homeowners and installers alike.

• Is it safe to install the Onyx Milazzo furniture surround on a plasterboard wall?

  No, it is not recommended to attach solely to a plasterboard wall. If installing on a studwork wall, ensure the fixings go through the timber stud for sufficient support.

• Can the Onyx Eclipse gas fire be operated if the glass panel is damaged?

  No. If any damage (scratches, cracks, or scores) is observed on the glass panel, it must be replaced before usage to ensure safety.

• How do I switch the Eclipse fire between manual and thermostatic modes?

  Use the provided Touch Control remote handset to navigate to the mode settings and select either manual operation or thermostatic control as desired.

• What should I do if the pilot light does not appear on my Onyx gas fire?

  Ensure the gas supply is connected and turned on. Press and hold the power button until 'pilot' appears on the screen, then release. If it still fails, consult the troubleshooting section of your user manual.

• Where can I find the serial number on my Onyx appliance?

  The serial number is typically located on the data badge found under the main burner (for gas fires) or on the appliance commissioning checklist provided with your product.
