Frequently asked questions
Common questions about ELM Leblanc from 3G Electric.
What is the temperature rating of the ELM Leblanc automatic air vent (SKU PCM14002)?
The ELM Leblanc automatic air vent, part number 87167338610, is rated for operation up to 1110°C. This high-temperature rating makes it suitable for use in boiler systems where the vent is exposed to elevated temperatures, such as near the heat exchanger or in the primary circuit. The 3/8" thread size is a common standard for boiler air vents, ensuring compatibility with many ELM Leblanc models. When replacing this component, verify that the thread size and temperature rating match your system's requirements to avoid premature failure.
Which ELM Leblanc circulation pump model is available, and what are its specifications?
3G Electric supplies the ELM Leblanc circulation pump MRA 15-30 2VI, part number 8716708577. This pump is designed for hydronic heating systems, providing forced circulation of hot water through radiators or underfloor loops. The '15-30' designation indicates a connection size of 1 1/2 inches (DN40) and a head range of up to 30 meters, though the actual head depends on the selected speed. The '2VI' suffix denotes a 2-speed version, allowing for adjustment to match system resistance. This pump is a direct replacement for many ELM Leblanc boiler models, ensuring proper flow rates and energy efficiency.
What is the function of the ELM Leblanc extractor (SKU PCM14003)?
The ELM Leblanc extractor, part number 87167338610, is a component used in the flue gas evacuation system of a boiler. It is typically a fan or impeller that draws combustion gases out of the combustion chamber and expels them through the flue. This is critical for maintaining proper combustion and preventing the buildup of toxic gases like carbon monoxide. The extractor is designed to operate at high temperatures, as it handles hot flue gases. When replacing an extractor, ensure it matches the original part's dimensions and electrical ratings to maintain safe and efficient operation.
What does the ELM Leblanc mini switch kit (SKU PCM14005) include?
The ELM Leblanc mini switch kit, part number 87167403810, includes a set of miniature switches used in the boiler's control system. These switches are typically used to detect the position of mechanical components, such as the water pressure switch or the flue gas thermostat. They send signals to the boiler's control board to initiate or stop operations. The kit contains the necessary switches and possibly mounting hardware, allowing for a complete replacement of worn or faulty switches. This is a common maintenance item, as switches can fail due to mechanical wear or electrical arcing over time.
What is included in the ELM Leblanc heat exchanger seal kit (SKU PCM14013)?
The ELM Leblanc heat exchanger seal kit, part number 87167263640, contains all the gaskets, O-rings, and seals required to service the heat exchanger in an ELM Leblanc boiler. The heat exchanger is a critical component that transfers heat from the combustion gases to the water. Over time, seals can degrade due to thermal cycling and water chemistry, leading to leaks and reduced efficiency. This kit allows a technician to replace all the necessary seals in one go, ensuring a proper seal and preventing future leaks. It is essential to use the correct kit for your specific boiler model to ensure a perfect fit.
What are the temperature ratings of the ELM Leblanc safety thermostats available?
3G Electric offers two ELM Leblanc safety thermostats: one rated for a maximum temperature of 120°C (part number 87167283490) and another rated for 85°C (part number 87167076180). These thermostats are designed to interrupt the gas supply or shut down the boiler if the water temperature exceeds the set limit, preventing overheating and potential damage. The 120°C thermostat is typically used in higher-temperature applications, while the 85°C version is common in standard domestic boilers. When selecting a replacement, match the temperature rating to the original part to ensure the boiler operates within its designed safety parameters.
