The provided document is an installation and maintenance manual for the Bellfires Smart Bell 65/60 MF gas fire. This decorative gas fire is designed to heat a room and can be installed as an insertion into an existing open fireplace or as a built-in appliance in a new fireplace. It is intended for use in a completely sealed or mechanically ventilated house without extra ventilation and/or fume extraction.
Function Description
The Smart Bell 65/60 MF is a room-sealed, independent gas-fired convection heater. It operates with a MagniFire double burner system, which provides both an upper and lower fire for a realistic flame effect. Combustion air is supplied to the appliance, and flue gases are extracted through a concentric flue system. The appliance features heat-resistant glass that keeps flue gases inside and closes off the combustion chamber.
Key components and their functions include:
- Control unit: Contains the gas regulator block, receiver, and the fan/light module, managing the appliance's operation.
- Inlet grate: Provides air to the fireplace.
- Outlet grate: Extracts heated air from the fireplace into the room.
- Concentric flue system: Supplies combustion air and extracts flue gases. It can be configured with a wall outlet or a roof-mounted outlet.
- Convection fan set (optional): Collects heated convection air and releases it into the room, enhancing heat distribution.
- Overpressure door: A safety device that opens for a short duration if an overpressure occurs, protecting the appliance.
- Burner bed: The top surface of the gas burner and grate, where the ceramic log set is placed.
- Pilot light burner: Provides a pilot light for ignition.
- Thermocouple: Detects if the pilot light is on, ensuring safe gas supply.
- Ignition electrode: Supplies a spark to ignite the pilot light.
- Gas regulator block: Manages gas flow and pressure to the burners and pilot light. It includes adjustment screws for pilot gas pressure and maximum burner pressure, which are factory set and sealed.
- Receiver: Processes signals from the remote control and communicates with the gas regulator block and fan/light module. It can be optionally connected to a 6 VDC adapter, a wall switch/domotica system, or a wifi-box for smartphone control via the Bellfires app.
- Fan/light module: Powers the convection fan (optional) and ambient light bulbs, and controls their functions.

- Checks:
- Check for leaks on gas pipes and connections using soapy water or a leak tester.
- Verify correct operation of the pilot light and main burner (quiet ignition, calm flame, flames increasing in height and changing from blue/yellow to yellow).
- Check gas supply pressure and burner pressure using inlet and outlet pressure taps on the gas regulator block.
- Ensure ambient lighting operates correctly.
- If a convection fan is installed, ensure it works correctly.
