Replacing a warantee primary heat exchanger on the noritz commercial tankless water heater. I am really happy they send replacement instructions with the heat exchanger. Because they crammed alot of stuff in a small space. All the tankless manufacturers use the rubber o-ring with clips for piping connections I am not a fan as they never send enough o rings to replace them all and they tend to leak.
