Rinnai 11i, 17i & 17e A Series LPG Conversion Kit (17I CONV NG-LPG) The Rinnai 11i, 17i & 17e A Series LPG Conversion Kit is the genuine, manufacturer-approved solution for converting a compatible Rinnai A Series continuous flow water heater from natural gas to LPG (propane). It's built to Rinnai's own standards and covers three models in the A Series range — the 11i, 17i, and 17e — with components precision-engineered to get gas regulation correct after conversion. This kit is well suited to rural properties or any location without access to mains natural gas, giving a cost-effective way to run an A Series appliance on LPG without sacrificing efficiency, safety, or long-term reliability. ⚠ Important: This conversion must be carried out by a Gas Safe registered engineer familiar with Rinnai appliances.
