Elektrogas Proof of Closure FAQ pt 2

Welcome to round two of our proof of closure FAQ! Q: Do I need “Proof of Closure?” A: Proof of Closure (POC) is required by NFPA86 if the burner capacity is 400K BTU/Hr or more; in these cases, proof of closure is required on one valve in series, while visual indication is required on both. Read More

FAQ: How do you wire devices with metric electrical connections?

Conduit For many years, the use of rigid or liquid-tight conduit was the standard for running wires to field devices, such as safety shut-off valves, pressure switches, and flame safety devices. Rigid conduit is thin walled metal tubing that helps to protect wires from mechanical damage and some environmental factors. Liquid-tight conduit is flexible and Read More

Elektrogas VMRNA Automatic Vent Valve

The Elektrogas VMRNA is a normally-open vent valve for industrial combustion systems. Because the valve is open when de-energized, VMRNA can be thought of as the opposite of a safety shut-off valve (closed when de-energized). How they work A reverse-acting solenoid valve, VMRNA is normally open. That means you must apply power to close the Read More

FAQ: What is a Package Burner?

A package burner is an industrial burner with its own dedicated blower. The standard scope of supply includes everything you need to safely run the burner: blower, air valve, air pressure switches, gas manifold (with filter, pressure reducing regulator, safety shut-off valves, gas pressure switches, etc.), ignition transformer, and flame safety. You are responsible for Read More

FAQ: What’s an Air Valve?

The term “air valve” can refer to several distinct pieces of equipment. Combustion requires heat, fuel, and oxygen, and we usually see oxygen provided as a component of ambient air (the air we breathe). The type and quantity of air valves on a system is determined by the application and the control scheme. We might Read More
