Technical information: - "Little brother" of our SUB heater - Power 20kW - Chimney connection Ø120mm - Cover with basic knob Use: The heater's fire box must be completely submerged during use, with at least 35 cm of water on top of it. The minimum water level is marked on the heater with a __MIN__ marking. Do not empty the hot tub before the fire in the heater has completely died out and the embers have cooled. In order to reach the specified power output, make sure to maintain a fair-sized fire in the fire box. Empty the heater of ashes after every use. Doing so increases the operating life of the grates. Be sure to read the manual thoroughly before using the heater.
