The 4" Single-walled, Stainless Steel Horizontal Vent Kit is for horizontal installations only.

You may need to purchase additional Eccotemp straight pipe. You will need to determine how many additional feet you will need and determine if you need a condensation drain. Also remember there is a maximum vent run of 20 feet, subtracting 4 feet for every 90-degree elbow in the run.

Includes:

  • (1) 4" x 90-Degree Elbow
  • (1) 4" x 12" Pipe
  • (1) 4" x 18" Pipe
  • (1) Termination Hood
  • (1) 4" Universal Adapter with Backflow Preventer
  • (1) 4" Adjustable Wall Thimble

Special gas vent kits are all made of AL-294C stainless steel and are category II/III and UL compliant. This vent kit is compatible with the installation of the Eccotemp 45HI Series, 6.8GB Series, EL22i Series, and SH22 Series whole home indoor tankless water heaters.

Wish I had found you sooner! Arrived quickly, good correspondence. I never wondered what about the status of my order. Wont hesitate to buy from you again.

Not criticisms but observations for what they're worth. Easy purchase but free delivery was slow: October 29 to November 6, 2025. Faster mail service makes this product's market price cost prohibitive on your sight. Time constraints are less a factor for small DYS homeowner projects, but larger project and contractors, it creates an undue consideration. Key and foundational shipping offsets of large big-box stores and online retailers are quantity purchases and 'membership fees,' the latter being the most important key.

I spoke with the person in the Technical Support department who listened and understood my complicated circumstances and made the perfect recommendation. I received the product within a couple of days and before the weekend ended, the job was complete and I am very pleased with results. Thank you, Eco Building Products for your support and product recommendation.
