Rinnai’s common flue system for water heaters

Rinnai has developed a common-header flue system for multiple-units installation of its Infinity condensing continuous-flow gas-fired water heaters. It eliminates the need for individual flue termination on modular banks of water heaters and large-scale commercial systems.
This flue system is designed to dovetail exactly with the Infinity Plus Cascade system, with no need for alterations to pipe lengths and no measuring — saving much time and effort for installers.
