Plumbing Installation Instructions
Steambath Generator Models: SMP-5, SMP-7, SMP-10, SMP-12 and SMP-15
The Steamist “SMP” Generator comes factory assembled,
carefully wired and tested.
WARNING: All electrical power should be turned OFF when
working with Steam Generator.
IMPORTANT: The Plumbing Installation must conform to local
and national codes.
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 Product Information section of the
Steamist website - www.steamist.com.
CAUTION: An improperly sized Steam Generator may NOT
produce the amount of steam necessary to reach selected
temperature.
b) For optimum performance, the Steam Generator should
be located as close as possible to the Steamroom,
Shower or tub enclosure using a ¾” copper pipe (1/2”
copper pipe is also acceptable, but not preferred). If the
steam pipe exceeds ten feet, it should be insulated using
appropriate pipe insulation rated for a minimum of 212º F.
Maximum steam pipe distance should not exceed a total
of fifty linear feet. Refer to Installation Suggestions on
page 4.
CAUTION: Do NOT install near flammable material such as
paints, thinners, gasoline, etc.
CAUTION: Steam generators must NOT be installed outdoors, in
moist, humid areas, in areas prone to freezing, or extreme heat
such as an unventilated attic. To do so will void the warranty.
c) 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 “SMP” Steam Generator
requires a ⅜" O.D. copper tubing to the fitting on the
generator for water inlet and a 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 - Rough in a water line, 120 PSI max,
to the hot or cold supply. A shut off valve with a
3/8” connection to the steam generator is to be
provided at the generator location (see Figure 4 on
page 3).
b) Steam Outlet - Rough in the steam line using a ¾"
copper or brass pipe; do NOT use black iron or
galvanized pipe; it will rust and discolor the wall of
the steambath. Do NOT use any plastic type pipe
or fittings. The steamhead location should be 12”
to 18" above the shower floor or 6" above the rim
of the bathtub, as far from the seating area as
possible.
CAUTION: No shutoff 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 allowing condensation to run back
toward the Steam Generator (preferred), or toward the
steamhead.

label and its additional safety information are packaged with the generator in the envelope containing the installation
instructions. If it is lost or missing contact Steamist (201-933-0700) for a replacement Publication No. 199. This publica-
tion along with all documents must be left with the owner.
