12L NG/LPG DP _ 3″ VERTICAL VENT KIT

3″ VERTICAL VENT KIT
12L NG/LPG DP – 12 FV __ 16L NG ETL __ 16L LPG ETL
According to ANSI code, gas tankless water heaters normally require stainless steel, category II/III vent pipe. This is due to the fact that gas tankless water heaters actually burn at a higher BTU rating. As such, the gas is extremely hot when it leaves the water heater, but cools quickly. This cooling process results in condensation which could eat through regular galvanized pipe.

We carry the Z-Flex vent pipe.
For tankless water heaters, it is single walled for models like the 12L NG DP – 12 FV, the 16L NG ETL and the 16L LPG ETL.

VERTICAL Termination INSTALLATION Requirements
You will need to purchase additional Z-Vent straight pipe.
You will need to determine how many additional feet you will need as well determine if you will need a condensation drain.
There is a maximum vent run of 20 feet, subtracting 4 feet for every 90 degree elbow in the run.
Just so you know ANY Vertical Venting Installation with more than a 5′ run length requires a vertical condensation drain pipe as well.

Please NOTE : A Termination Hood Or Straight Pipe Section Must Be Equipped With A Damper/Backflow Preventer Is Mandatory To Ensure That Freezing Air Does Not Come Back Down Through The Vent Stack.
