Plumbing Installation Instructions
Steambath Generators Model: TSG-15
The Steamist “TSG” 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 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.
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 Steamroom/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, or Basement near bath
area. The serial number plate should be visible and the
Steam Generator should be accessible for service. Refer
to Installation Suggestions on 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 flammable materials such as paints, thinners,
gasoline, etc.
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 is required for the water supply and steam
line this should be completed before the walls are
closed. For operation, the “TSG” 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 - 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 4 on page 3). Solder a piece of ⅜"
copper tubing into tee. Rough-in for water supply is
now complete.
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 steambath. 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 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.

Plumbing Installation Instructions
3. Steam Generator Installation
The Steam Generator should be mounted in a location convenient
for hook-up and service by the plumber and electrician.
CAUTION: The steam generator is designed to be used ONLY in
an upright and level position, to do otherwise would damage the
unit and void the warranty.
a) The Steam Generator can be mounted to a wall or set
on the floor. However, the unit must be secured. To
secure the unit to a vertical wall, loosen the two screws
holding the electrical access cover, remove cover (see
Figure 1). Located inside the cabinet near the top left
and right corners are mounting holes. Place top cover
back and secure.
b) Connect the 3/8" water supply, described in Section 2, to
the Steam Generator by first soldering a 3/8" valve into
the previously installed water line. The valve must be
kept in an open position during normal operation. In
areas where high water pressure may be a problem a
water hammer arrestor or a pressure regulator should
be installed. Complete water supply by connecting 3/8"
copper tubing from the valve to the water inlet compres-
sion fitting. Refer to Figure 2.
IMPORTANT: Do NOT use a “saddle valve” or piercing
type valve for water connection.
c) Connect the steam line from rough-in location described
in Section 2 to the ¾" nipple on the Steam Generator
using a union.
d) In the shower, place the center of the escutcheon
onto the steam pipe and screw the steamhead into
place. Care must be taken not to scratch the
steamhead or escutcheon with wrench. After the
plumbing connections are complete the electrician
may finish wiring the unit.

1. Make sure the ¾" nipple protrudes beyond the tile
approximately ½". (See Figure 3)
2. Wrap the nipple with pipe sealant tape.
3. Put a bead of silicone around the outer edge of the Back
Plate (see Figure 3) and center the Back Plate over the pipe
in an upright position. While holding it in place, screw the
Center Hub onto the nipple, using a ⅜" hex key to tighten.
4. The Center Hub MUST be aligned with the four walls in the
vertical and horizontal position (See Figure 3a). Make sure
the steamhead O-ring is fully seated into the Back Plate.
If the nipple is sticking out too far the O-ring will not make
a proper seal and the nipple must be adjusted.
5. Apply a small amount of silicone at the back center point
of the Cover Plate.This will aid in preventing movement
of this plate. (See Figure 3a)
6. Place the Cover Plate over the Center Hub. This is
accomplished by first hooking the top and then snapping
the bottom into place.
7. Adjust the Back Plate and Cover Plate to line up
squarely, and clean excess silicone with rubbing alcohol.
