Producte acabatview
The Allanson Ignition Transformer (Model 2721-628G) is a critical component in oil burner systems, responsible for generating the high voltage required to ignite the fuel. It converts standard line voltage to a high-voltage spark, ensuring reliable ignition.
This image shows the Allanson Ignition Transformer, Model 2721-628G, from a front-top perspective. The primary label is visible, indicating "PRIMARY 120 V 60 HZ 250 VA" and "SECONDARY 10,000 V 23 MA". Two high-voltage terminals with springs are visible at the top, along with input wires extending from the sides. The unit is black with a green circular sticker on the side.
This image displays a side view of the Allanson Ignition Transformer. One of the high-voltage terminals with its spring is clearly visible, along with the input wiring. The mounting bracket is also visible on the side, and the green circular sticker is prominent on the main body of the transformer.
Configuració i instal·lació
Installation of the ignition transformer should only be performed by a qualified HVAC technician or electrician. Incorrect installation can lead to equipment damage, fire, or serious injury.
- Desconnexió d'alimentació: Before starting, ensure all electrical power to the oil burner and heating system is completely disconnected at the main service panel. Verify with a voltage provador.
- Access Old Transformer: Locate the existing ignition transformer on your Becket A, AF, or AFG burner. Note its mounting position and wiring connections.
- Desconnecteu el cablejat: Carefully disconnect the primary (low voltage) and secondary (high voltage) wiring from the old transformer. Label wires if necessary to ensure correct reconnection.
- Remove Old Transformer: Unmount the old transformer from its bracket or housing.
- Mount New Transformer: Mount the new Allanson 2721-628G transformer in the same location and orientation as the old one. Ensure it is securely fastened.
- Connecteu el cablejat:
- Connect the primary (120V) input wires to the designated terminals on the new transformer. Refer to the burner's wiring diagram for specific connections.
- Connect the secondary (high voltage) output wires to the electrodes of the oil burner. Ensure a secure and proper connection to the spark gap.
- Verifica les connexions: Double-check all wiring connections for tightness and correctness according to the burner's specifications. Ensure no wires are pinched or exposed.
- Restaura l'alimentació i prova: Once all connections are secure and verified, restore power to the burner. Initiate a call for heat and observe the ignition sequence. The transformer should produce a strong, consistent spark.
Principi de funcionament
The Allanson Ignition Transformer operates by stepping up the incoming 120V AC line voltage to a high voltage (10,000V) at a low current (23mA). This high voltage is then applied across the burner electrodes, creating an electrical arc (spark) that ignites the atomized fuel oil. The transformer is designed for intermittent duty, meaning it only operates during the ignition cycle of the burner, typically for a few seconds until stable combustion is established.
Manteniment
Regular maintenance helps ensure the longevity and reliable operation of your ignition transformer. All maintenance should be performed by a qualified technician with power disconnected.
- Inspecció anual: During routine burner servicing, inspect the transformer for any signs of physical damage, corrosion, or overheating (discoloration).
- Comprovació del cablejat: Verify that all primary and secondary wiring connections are secure and free from fraying or insulation damage.
- Neteja: Keep the transformer and its surroundings free from dust, dirt, and oil residue, which can impede heat dissipation and lead to premature failure.
- Estat de l'elèctrode: While not directly part of the transformer, ensure the burner electrodes are clean, properly gapped, and free from cracks or carbon buildup, as their condition directly impacts the transformer's performance.
