I’m looking to replace my power vent tank water heater with tankless but my vent is ABS And goes straight up for about 10 feet.
The tank water heater I’m looking at claims to be universal venting compatible but I’m wondering if I’m missing anything. The vent pipe is ABS goes up 10 feet to a 90 then 5 feet to another 90 before going out to the side of the house on a 45.
The tankless is a non condensing indoor natural gas RHEEM.
