The Steamist "SM" Generator comes factory assembled,
carefully wired and tested.
The Plumbing Installation must conform to local and
national codes. All electrical power should be turned OFF
when working with Steam Generator.

1. Pre-Installation

a) Be sure that the proper size Steam Generator has
been selected by using the sizing page in the "Full
Line Brochure," "Pricing Guide," "The Generator
Sizing Guide," "Architectural Guidelines," or in the
Residential Systems/Steambath
Information section of the Steamist web site -
www.steamist.com.
CAUTION: An improperly sized Steam Generator
may NOT produce the amount of steam necessary
to reach selected temperature.
IMPORTANT: Refer to page 4 for model required
for cubic foot rating.
b)
The Steam Generator should be located as close as
possible to the Steam Room/Shower or tub
enclosure. Steam pipe should NOT exceed
twenty-five feet in length. If the steam pipe exceeds
ten feet, use an appropriate pipe insulation rated for
a minimum of 212°F. Possible locations include
Vanity, Closets, Attic (insulated), or Basement near
bath area. The serial number plate should be visible
and the Steam Generator should be accessible for
service. Refer to Installation Suggestion on the
page 4. Do NOT install Generator outdoors, in a
moist humid area, or in an area where parts may
freeze or corrode. Also, do NOT install near
c) flammable materials such as paints, thinners,
gasoline, etc.
The steam line and safety valve reach a
temperature of 212°F during operation and should
be appropriately protected to prevent personal
injury by accidental contact.

2. Plumbing Rough-In

Plumbing rough-in is required for the water supply and
steam line, this should be completed before the walls
are closed. For operation, the "SM" Steam Generator
requires a ⅜" O.D. copper tubing to the fitting on the
generator for water inlet and ¾" copper or brass pipe for
steam outlet.

NOTE: Safety Valve should be connected to a
minimum ¾" indirect waste or as required by local
plumbing codes. In the unlikely event this valve should
open, the discharge must be directed to prevent
damage to the home.
a)
Water Inlet - A water line should be roughed-in from
existing ½" hot or cold water pipe. Using a ½" x ⅜"
tee, cut and solder tee into the existing water line.
(See Figure 3 on page 3). Solder a piece of ⅜"
copper tubing into tee. Rough-in for water supply is
now complete.
Product b)
Steam Outlet - Rough-in the steam line using a
minimum of a ¾" copper or brass pipe, do NOT use
black iron or galvanized pipe, it will rust and discolor
the wall of the steam bath. The steamhead location
should be 18" above the shower floor or 6" above
the rim of the bathtub, as far from the seating area
as possible.
CAUTION: No shut-off valve can be installed in the
steam line. Do NOT create traps or valleys in this line
which would trap condensation and block the flow of
steam. The steam pipe should be pitched toward the
Steam Generator allowing condensation to run back
toward the Steam Generator (preferred), or toward the
steamhead.
