Installation & Safety

Confirm the complete furnace model and original igniter before installation. Turn off electrical power and isolate the gas supply where fitted. Follow the model-specific service instructions and have a qualified technician perform the repair. Do not test the igniter while energized or bypass any safety control. Restore all guards and complete the required safety checks before operation.

Always verify your model number before ordering. Check the rating plate inside or near the furnace cabinet to confirm compatibility.
