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.

What's Included

  • 6" to 9" Aluminum Eccentric Increaser

Design Considerations

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.

Corrossion Resistance

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.

      Quick glow up
      Color: Glistening Bronze #03, Size: 1 Fl Oz (Pack of 1)
      This is a great bronzing shimmer for a little added glow before walking out the door! It's very lightweight and goes on very smooth with brush. I ended up buying and using a larger kabuki brush to brush on faster but the brush it comes with works ok as well. It's the perfect amount of bronze and shimmer.. not glittery or over the top and doesn't have a smell. Doesn't transfer on clothes but I always let it dry a few minutes before putting on clothes.

      Beautiful Shimmer
      Color: Rose Gold #01, Size: 1 Fl Oz (Pack of 1)
      This worked well for a wedding. I thought it would be a little more bronzier but I loved the sparkle. It is my first time using a body shimmer though, so it did what I bought it for and next time just need to self tan prior!

      Another Amazing Product from SKIN1004
      I own at least 4 products from SKIN1004, because they really are a great skin care brand to invest in with. For reference, I have dry sensitive skin, I am prone to dark spots, some acne, dry patches and bigger pores. I have always had bad experiences with toner's so I was really hoping this would work for me. And it did more than that! I do believe my acne has gone down since using this, and to really test it out I finished the bottle after 5 and half months of daily morning and nighttime use. My skin feels smoother and bit brighter, more than anything it really keeps your skin clean without drying it out. It doesn't have a particular smell, the consistency is like water, and when you apply it is a bit tacky but no worries once it dries down completely, that goes away. This toner could be used by all skin types in my opinion. I will be trying their brightening toner soon, which I am even more excited about! Would repurchase.
