Chimney for gas, oil, and diesel – 6” to 48”
Waterproof envelope system
The VIP model chimney is a prefabricated chimney made for use with forced draft and negative or neutral draft appliances, such as high-pressure steam boilers, building heating equipment, industrial furnaces, kilns, hoods, and ovens. It can also be used with diesel exhaust engines and gas turbines. The VIP model chimney was designed as a complete venting system capable of functioning in positive forced draft and negative or neutral pressure conditions. It was designed and tested for flue gas temperatures of up to 537°C (1000° F). Fire safety clearance for combustibles is dependent on your maximum operating temperature; the maximum allowable continuous flue gas temperature for the VIP chimney is 760° C (1400° F).
The VIP is a double wall insulated chimney. Its inner lining is equipped with a graphite pressure seal, while its outer casing uses a silicone pressure seal. To allow for a variety of applications and fuels, the VIP’s chimney flue and casing are available in several materials and thicknesses. The standard VIP chimney, which is suited to most applications, is produced with 1” of high-temperature, high-density insulation. For non-standard custom applications, the VIP model is available with either 2” or 4” of insulation. We recommend using stainless steel chimney lengths for all corrosive or exterior environments.Technical sheet
