4. Setup uye Kuiswa
Follow these steps for the correct installation of the igniter kit:
- Kugadzirira:
- Ensure the boiler is completely shut down and cooled.
- Turn off the main power supply to the boiler at the circuit breaker.
- Close the main gas supply valve to the boiler.
- Access the Igniter:
- Locate the existing igniter assembly on your ECO 155 Boiler. Refer to your boiler's specific service manual for exact location.
- Carefully disconnect any electrical wiring connected to the igniter. Note the wiring configuration for reinstallation.
- Remove Old Igniter:
- Unscrew the mounting screws holding the old igniter in place.
- Gently remove the old igniter and its gasket. Dispose of them properly.
- Isa Nyowani Igniter:
- Place the new gasket onto the mounting surface, ensuring it aligns with the screw holes and the igniter opening.
- Carefully insert the new Weil-McLain 383-700-187 igniter into position, aligning its mounting plate with the gasket and screw holes.
- Secure the igniter with the new mounting screws provided in the kit. Tighten them firmly but do not overtighten.

- Visually inspect all connections for tightness and proper seating.
- Ensure no tools or debris are left inside the boiler compartment.
5. Operating Principles
The Weil-McLain 383-700-187 Igniter is a critical component in the ignition sequence of your ECO 155 Boiler. When the boiler calls for heat, the control system sends an electrical signal to the igniter. The igniter then heats up rapidly to a high temperature, becoming incandescent. Simultaneously, gas flows to the burner. The hot surface of the igniter ignites the gas, initiating the combustion process. Once a flame is established and confirmed by the flame sensor, the igniter typically de-energizes, and the boiler continues its heating cycle.
6. Kuchengeta
Regular inspection of the igniter is recommended as part of your boiler's annual maintenance schedule. A qualified service technician should perform these checks.
- Visual Inspection: Check the ceramic insulator for cracks or damage. Inspect the electrode for signs of erosion, carbon buildup, or discoloration.
- Kuchenesa: If minor carbon buildup is present, gently clean the igniter surface with a soft brush. Avoid abrasive materials that could damage the ceramic or electrode.
- Wiring: Ensure all electrical connections to the igniter are clean, tight, and free from corrosion.
- Kutsiva: If the igniter shows significant wear, damage, or fails to ignite consistently, it should be replaced with a genuine Weil-McLain 383-700-187 Igniter Kit.
7. Kugadzirisa matambudziko
If your boiler is experiencing ignition issues, consider the following common problems related to the igniter:
| Dambudziko | Zvinogona Kukonzera | Solution |
|---|---|---|
| Igniter does not glow | No power to igniter, faulty igniter, loose wiring. | Check power supply to boiler. Inspect wiring connections. Test igniter for continuity (if qualified). Replace igniter if faulty. |
| Igniter glows but no ignition | Insufficient gas supply, igniter not hot enough, igniter positioned incorrectly, faulty gas valve. | Verify gas supply is open. Check igniter for carbon buildup. Ensure igniter is correctly positioned. Consult a qualified technician for gas valve inspection. |
| Kudzima kwepakati | Weak igniter, fluctuating power, dirty flame sensor. | Inspect igniter for wear. Check electrical connections. Clean flame sensor. |
Note: For complex issues or if you are unsure about any troubleshooting step, always contact a qualified HVAC technician.
