Boiler Uptake Fire and Exhaust Gas Economiser Fire

– Electronic ignition: Most boilers uses electric power (electrode) to generate ignition to fire up while fuel or gas flows in. Sometimes, due to high temperature or age, the electrode cable insulations might surface to the body of the boiler causing high voltage, then trip the breakers for safety.
