Some of the Bosch Retail gas tankless water heaters can be converted from one gas type to the next, i.e. from Natural Gas (NG) - Liquid Propane (LPG) and also from LPG - NG. The Gas Conversion Kit, part #8719002176 includes a jumper for placement on the control board, a set of instructions for calibrating the gas and air mix and also some stickers to be placed on the heater stating it has been converted.
The tools required for the gas conversion are:
- Flat and Phillips Screwdrivers
- #40 torx driver
- Digital CO2 Gas Combustion Analyzer
- This procedure must be performed by a licensed gas technician
The Bosch Retail Gas tankless water heaters that CAN be converted using the gas conversion kit are the 2700ES/2400ES/2400E/2400EO/250SX/250SXO.
The Bosch Retail Gas tankless water heaters that CANNOT be converted are the 1600H/1600P/1000P and all of the 125 series heaters as they are not designed or approved at all for gas conversion.
