Product Details
Product Details
- Use to add length to a straight length of type B gas vent
- Strong, durable galvanized steel outer pipe has internal spacing beads to assure a uniform insulating air space between pipe walls
- Each end is die formed to assure uniform sizing for strong, easy to connect joints. In Canada, some lengths are available in galvalume steel outer pipe
- The double wall (pipe within a pipe) construction with its built-in air space, provides permanent insulation and keeps the inner pipe hot and the outer pipe relatively cool
- This construction creates quick, strong vent action reducing condensation in the pipe and overheating of nearby enclosure surfaces
