Waterworks’ steam generators are tested by Intertek-ETL Laboratory. The steam generators come assembled
and ready for installation. Check that the size and rating of the generator is suitable for your application, refer
to the Steam Room Construction and Generator Guide (Waterworks doc. 4211-36).
These steamers may be connected as a ganged system where one steamer controls one or two other steam-
ers. Bath controls connect to the primary steamer and the primary steamer connects to the second steamer
(and third steamer, if installed). This provides more power for large rooms and light commercial use. See
appendix to this document for details. We recommend choosing steamers which are closely matched in power.
The highest kW steamer should be the primary unit. Each steamer should have its own automatic drain.
For commercial use, we recommend checking with your local inspectors to confirm the steamer system is
acceptable for your use. Many jurisdictions will require an ASME boiler for commercial use: WATERWORKS
steamers are not boilers.
Note: These steamers may be configured for single or three phase power during installation
IMPORTANT
An exhaust fan installed outside the steam room is strongly recommended to remove excess steam
from the bathroom or shower area.
