3. Hua Neke Atuview
The Riello 24V Transformer (AL1008) is a critical component for the control system of various Riello oil burners. It converts higher voltage input to a stable 24-volt output required for the burner's control circuitry, including the thermostat and other low-voltage nga waahanga.

Whakaahua 3.1: Components of the Riello 24V Transformer kit. Shown are the main transformer circuit board with wiring, a metal mounting bracket, two wire nuts, two mounting screws, and a cable gland with a rubber grommet. These parts facilitate secure installation and electrical connection.
The kit typically includes the transformer module, a metal mounting bracket, wire connectors, and screws for installation. The transformer module itself consists of a circuit board with the transformer, relay, and terminal connections for wiring.
4. Tatūnga me te Tāuta
This 24V transformer is designed to mount under the burner cover of compatible Riello oil burners. Refer to your specific burner's manual for detailed wiring diagrams and safety precautions.
4.1. Rarangi Arowhai i mua i te whakaurunga
- Ensure the main power supply to the burner is disconnected at the circuit breaker or fuse box.
- Confirm the transformer is compatible with your Riello burner model (R40, F3, F5, F10, F15, F20, BF3, BF5 series).
- Gather necessary tools: screwdriver, wire strippers, multimeter (for verification).
4.2. Tohutohu Whakauru
- Locate the designated mounting area under the burner cover. This is typically where the original transformer or relay was located.
- Attach the metal mounting bracket to the transformer module using the provided screws, if not pre-assembled.
- Secure the transformer assembly to the burner chassis using the mounting screws. Ensure it is firmly attached and does not obstruct any moving parts or ventilation.
4.3. Tohutohu Waea
The transformer has input terminals for the main power supply and output terminals for the 24V control circuit. The specific wiring configuration will depend on your burner model. Always consult the wiring diagram provided with your Riello burner.
- Input (High Voltage): Connect the main power supply wires (typically 120V or 240V, depending on your system) to the designated input terminals on the transformer. Use the provided wire nuts for secure connections.
- Output (24V Control): Connect the 24V output wires from the transformer to the burner's control circuit, including the thermostat connection. The transformer is specifically designed as a 24 Volt Switching Relay.
- Ensure all connections are tight and insulated. Use the cable gland to secure incoming wires and protect them from strain or damage.
- Double-check all wiring against the burner's schematic before restoring power.
5. Nga Tohutohu Whakahaere
The Riello 24V Transformer operates automatically as part of the burner's control system. Once properly installed and wired, it will provide the necessary 24-volt power when the burner calls for heat. There are no user-adjustable settings or direct operational controls on the transformer itself.
- After installation, restore power to the burner.
- Initiate a call for heat from your thermostat to verify proper operation of the burner and the new transformer.
- Listen for the normal operation sounds of the burner and observe any indicator lights.
6. Tiaki
The Riello 24V Transformer is designed for long-term reliability and typically requires minimal maintenance. However, periodic inspection is recommended as part of your regular burner maintenance schedule.
- Tirohanga Tau: During your annual burner service, have a qualified technician inspect the transformer and its wiring.
- Taki Hononga: Me whakarite kia mau tonu ngā hononga hiko katoa, ā, kia kore e waikura.
- Tirotiro Ataata: Look for any signs of overheating, discoloration, cracked insulation on wires, or physical damage to the transformer module.
- Te horoi: If dust or debris accumulates, gently clean the transformer and surrounding area with a soft, dry brush or compressed air. Ensure power is disconnected before cleaning.
7. Te Raru
If your burner is not operating correctly after transformer installation, consider the following troubleshooting steps. Always disconnect power before inspecting components.
| Raruraru | Take pea | Rongoā |
|---|---|---|
| Burner does not start (no power to controls) |
|
|
| Intermittent burner operation |
|
