Lochinvar® Corporation introduces the Shield Combustion System™, designed to protect against the ignition of flammable vapors and provide customers years of dependable and efficient operation.
Designed and manufactured with engineering precision, Lochinvar’s Shield Combustion System meets the American National Standards Institute (ANSI) construction standard for residential gas-fired water heaters. Effective July 2003, the ANSI code will require residential water heater combustion technology to resist the ignition of flammable vapors outside the water heater. Lochinvar’s new technology will not change the height, width or gallon capacity of any water heater effected by this standard.
The key component of the Shield Combustion System is the Lock-Shield flame arrestor plate made from 304L stainless steel. This plate is designed and manufactured with 18,000 geometrically engineered air louvers. These air louvers prevent ignited flammable vapors from traveling backward out of the combustion chamber and outside the water heater.
