SECTION 1: GENERAL INFORMATION
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 steamers. 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.
CAUTION
Electrical grounding is required on all
WATERWORKS Steam bath Generators.
All electrical supplies should be
disconnected when servicing generator.
All wiring must be installed by a licensed
electrical contractor in accordance with
local and national codes.
All plumbing must be installed by a
licensed plumber in accordance with all
applicable local and national codes.
Steam generators are
for indoor use only.
Steam generators are not for
space heating purposes.
Be certain that steam bath enclosures
are properly sealed to avoid water
damage from escaping steam. It is
recommended that 100% silicone caulk
be used to seal all pipes and fittings.
Steam must be prevented from escaping
into the wall cavity.
Never shut off the water to a
steam generator that is in use.
Electric Shock Hazard - High voltage
exists within this equipment. There
