22L NG DP – 45 HI _ 4″ VERTICAL VENT KIT

22L NG DP – 45 HI _ 4″ VERTICAL VENT KIT
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 like the 22L NG DP – 45 HI.
