Ka mutu te huaview
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.

The mounting bracket is also visible on the side, and the green circular sticker is prominent on the main body of the transformer.
Tatūnga me te Tāuta
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.
- Momotu Hiko: 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 Kaiwhakamatautau.
- Access Old Transformer: Locate the existing ignition transformer on your Becket A, AF, or AFG burner. Note its mounting position and wiring connections.
- Momotu Waeaea: Carefully disconnect the primary (low voltage) and secondary (high voltage) wiring from the old transformer. Label wires if necessary to ensure correct reconnection.
- Tangohia te Whakawhiti Tawhito: Unmount the old transformer from its bracket or housing.
- Tāutahia te Whakawhiti Hou: Mount the new Allanson 2721-628G transformer in the same location and orientation as the old one. Ensure it is securely fastened.
- Tūhono Waea:
- 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.
- Manatoko Hononga: Double-check all wiring connections for tightness and correctness according to the burner's specifications. Ensure no wires are pinched or exposed.
- Whakaora Hiko me te Whakamatau: 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.
Kaupapa Whakahaere
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.
Te tiaki
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.
- Tirohanga Tau: During routine burner servicing, inspect the transformer for any signs of physical damage, corrosion, or overheating (discoloration).
- Taki Waea: Verify that all primary and secondary wiring connections are secure and free from fraying or insulation damage.
- Te ma: Keep the transformer and its surroundings free from dust, dirt, and oil residue, which can impede heat dissipation and lead to premature failure.
- Tikanga Hiko: 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.
