INSTALLATION GUIDE FOR MRSTEAM RESIDENTIAL GENERATORS
Read these instructions before installation or service.
Although each MS steambath generator
has been fully qualified for shipment by MrSteam, the
following must be reviewed for proper,
safe and enjoyable steam bathing.
Verify that the model and accessories are correct, including
incoming line voltage.
Ensure steambath generator has been correctly sized
for the steambath room. Pay particular
attention to room volume and construction. If any questions,
please refer to the Sizing Chart.
Marble or glass walls or ceilings, or exterior walls
enlarge the room’s size, requiring a
generator larger than one based only on the room’s
cubic foot (L x H x W) volume.
The physical size of the unit, clearance for plumbing
servicing and its distance from the steam
room must all be considered before final installation.
MrSteam steam generators are connected to 240V line
voltage and contain live electrical
components. All installation and service to be performed
by qualified electricians and plumbers
only. Installation or service by unqualified persons
may void the warranty.
Recommendations for Steamroom Construction
- The steam room must be completely enclosed with
full doors, walls, floor and ceiling. All
crack and joints must be filled with a silicone sealer.
- The steam room must be watertight: walls, ceilings
and floors must be made of waterproofed
materials such as tile, cement, marble, etc. Ceramic
tile is the most commonly used material
for steam rooms. It should be well grouted and properly
sealed. Avoid the use of untreated
and exposed materials that are susceptible to decay
- Insulation should be utilized within the walls,
- Normal ceiling height is 7 feet 6 inches: the ceiling
should be sloped 2 inches per foot in order
to prevent condensation from dripping on the occupants.
The ceiling can be sloped from the
center to minimize height reduction.
- The steam room should have at least one bench for
bather's comfort. It should be sloped
slightly to provide for condensate runoff.
- The steam room should contain at least one drain
for condensate runoff and cleaning.
- Flooring should be skid-resistant for safety.
- Vents inside the steam room are not recommended,
but if used, they must be positive closing
vents. The vents must form a vapor-tight seal. Ducts
must be waterproof.
- If a skylight or window is used, it must be double-pane,
and skylights must be closed off and
sealed at the ceiling height.
- The shower door used must be water-tight.
Locating the Steam Generator Unit
Select a location as near as possible to the steam room.
Typical locations include: closet, vanity
cabinet, insulated attic, or basement.
- Locate the steambath generator as close as practical
to the steam/shower room and within 50
feet of the steam room.
- Do not install the steambath generator inside the
- Do not install the steambath generator outdoors.

- Do not install the steambath generator near combustible
or corrosive materials and chemicals.
- Install the steambath generator on a solid and
- Install the steambath generator in an upright position.
- Install an antiwater-hammer device if required.
- Provide access to both ends of steambath generator
- Steam line, safety valve, and drain valve become
hot during operation. Provide appropriate
- MrSteam controls can be located inside the steam
room or on the outside of the steam
room. If the Smart/Two or Smart/Plus controls are
located outside the steamroom, a remote
sensor (part number MSNC) is required.
Note: The Smart/One, Smart/Remote, Smart/Two and Smart/Plus
controls are UL Approved for
installation and operation in a wet location.

- Install each unit as in a single installation.
- Connect the SMART/PLUS control to either unit per
instructions supplied with the
- Using the interconnecting cable provided (PN 103608)
connect the Black plug to the Liquid
Level Control Board Terminal marked TANDEM in the

- Connect to hot or cold water line. Hot water line
is preferable. Hot water should not exceed
160 degrees F. Softened water is also preferable.
- Provide a shutoff valve in supply line.
- Do not overheat inlet solenoid valve with solder
connections. Overheating will damage parts.
- Flush inlet water line thoroughly before making
connection to unit.
- Strainer is required if there are solid particles
in the water.
- For best performance, water pressure should be
15 to 20 psig.
- Provide antiwater-hammer device if required.
