Using tables from the National Fuel Gas Code or our Sizing & Application Guide, determine the diameter of venting required. The Sizing & Application Guide also offers tips on good design including multi-appliance system sizing and design. The System Design and Installation Guide is an additional resource.
UL-listed as a support and firestop, the gripper support is strong enough to hold up to 30 feet of vent pipe. It installs very quickly and allows for adjustment of the pipe to wherever needed. A ring on the bottom provides the UL-required, one-inch clearance to combustibles (3" to 6" only; 7" to 10" are not UL-listed). No tools are required.
