Instructions for the Range Powermax 155

Updated April 17, 2017

The Range Powermax 155 is a thermal store gas-electric boiler system used to heat water. This design combines both a hot water cylinder and a standard boiler unit together in a single appliance. Users can set specific times for the unit to turn on and off throughout the day, or use the preset times already programmed into the system. The boiler unit needs to be lit before the system is functional, so this system is not recommended for use by children.
