INSTALLATION GUIDE FOR MRSTEAM RESIDENTIAL GENERATORS

Before Installing
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.

Warning!

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

  1. 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.
  2. 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 or corrosion.
  3. Insulation should be utilized within the walls, ceilings, etc.
  4. 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.
  5. The steam room should have at least one bench for bather's comfort. It should be sloped
    slightly to provide for condensate runoff.
  6. The steam room should contain at least one drain for condensate runoff and cleaning.
  7. Flooring should be skid-resistant for safety.
  8. 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.
  9. If a skylight or window is used, it must be double-pane, and skylights must be closed off and
    sealed at the ceiling height.
  10. 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.

  1. Locate the steambath generator as close as practical to the steam/shower room and within 50
    feet of the steam room.
  2. Do not install the steambath generator inside the steam room.
  3. Do not install the steambath generator outdoors.
  4. Do not install the steambath generator in an unheated attic or basement where water could freeze.
  5. Do not install the steambath generator near combustible or corrosive materials and chemicals.
  6. Install the steambath generator on a solid and level surface.
  7. Install the steambath generator in an upright position.
  8. Install an antiwater-hammer device if required.
  9. Provide access to both ends of steambath generator for servicing.
  10. Steam line, safety valve, and drain valve become hot during operation. Provide appropriate
    protection.
  11. 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.
