1. † Amps are for 240/1PH rated units.
2. ‡Wire size (AWG) based on minimum 90˚C rated THHN copper
conductors. Refer to the National Electrical Code for other types of
conductors.
3. *Dimensions are for generator only, without AutoFlush or plumbing
features. See page 8 for complete dimensional information.
4. **Shipping weight is for generator only, without control or steamhead.
5. †† Water usage based on 20 minutes of operation.
6. For steam rooms constructed of acrylic or synthetic materials, subtract
15% from the room volume.
7. The MrSteam Sizing Chart allows for up to 60 feet of insulated steam
piping from the generator to the steam room. If a 60 foot piping is
exceeded consult with factory.
8. Occasionally a steam room has unforeseeable or hidden construc-tion
that requires special sizing or other consideration. MrSteam is not
responsible if unconventional and/or unforeseeable materials or
construction details result in a unit that does not operate to specifi-
cation. If the sizing chart does not include the required options, please
contact MrSteam to review sizing.
