To calculate the generator size required, multiply the length x width x height of the steam room. (Maximum recommended ceiling height is 8 feet.)

For rooms made of natural stone, multiply the cubic volume by 1.75 (stone requires more power to heat)

For rooms exceeding 550 cubic feet, generators may be ganged together to achieve required capacity.

Each generator will require its own power source as described in the chart above.

Example: Room size 750 cu ft, power available 240V 1 phase:
   Use two AK11 generators.
   Requires one 60A circuit for each AK11 steamer
   (total of two circuits)

Example: Room size 925 cu ft, power available 240V 1 phase:
   Use one AK11 ( requires one 60A circuit) plus one AK14 (requires 2
   circuits, one 30A + one 50A)

At least one control required, regardless of quantity of generators. Additional controls may be connected.
