12L NG/LPG DP _ 3″ HORIZONTAL VENT KIT

3″ HORIZONTAL VENT KIT
12L NG/LPG DP – 12 FV __ 16L NG/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 model units like the 12L NG DP – 12 FV, the 16L NG ETL and the 16L LPG ETL.
