Corr/Guard® is tested and listed to UL 1738 for positive pressures up to 15" w.g., featuring a durable AL29-4C super ferritic stainless steel flue designed for extreme resistance to chloride ion pitting, crevice corrosion, stress corrosion cracking, and corrosion in moderately reducing environments. FCS Corr/Guard® incorporates an integral joint sleeve for easy joint alignment and aids in shingle condensate across the joint, preventing excessive joint corrosion and leakage. FCS products are manufactured with continuous laser-welded seams and casings, improving durability and reliability and increased efficiency.
Single and Double-Wall Positive Pressure Special Gas Vent engineered for venting today’s high-efficiency natural gas-burning or propane-fired appliances, categories II, III, and IV as defined by the Standard for Gas-Fired Central Furnaces, ANSI Z21.47 and NFPA 54.
When venting gas appliances always consult the appliance installation instructions. Horizontal runs, elbows, offsets, vertical height, may be limited by appliance performance specifications.
Horizontal runs must slope a minimum of ¼": 12" (6mm-305mm). Neutral or negative pressure systems must slope upward – away from the appliance. The positive pressure within the vent may slope upward or downward. Provide condensate drainage where required.
Vertical runs are directional-specific and must be properly supported. Supports are required above every offset to prevent vertical loading on elbows.
Corr/Guard products are designed for use on today’s highly efficient condensing appliances. UNS S44735 (i.e. AL29-4C), a Superferritic Stainless Steel was the first steel to successfully exceed the requirements of UL 1738, “Standard For Venting Systems For Gas-Burning Appliances, Categories II, III, and IV." It is considered the benchmark for condensing flue materials.
For use with high-efficiency category II, III, and IV natural gas-burning or propane-fired appliances including gas boilers, furnaces, booster heaters, pool heaters, unit and radiant tube heaters, and direct vent appliances.
