Steambath Generators

The Steamist “TSG” Generator operates with only “TSC” series
controls mounted inside and an optional TSX or TSR remote
control located outside the steamroom. It’s small enough in size
to be tucked away using very little space in a vanity, closet, or
basement, but large enough to provide steam for most residential
baths.

The Steamist “TSG” Steambath Generator comes factory
assembled, carefully wired and tested.

NOTE: A “TSC” series control is required to operate the "TSG"

generator.

1. Pre-Installation

a) Proper electrical supply (208 or 240 Volt): See rating

label on Steam Generator and Chart on page 4.
Determine proper size of wire, voltage, amperage, and
phase for the Steam Generator. 90°C copper wire is
required for generator connection.

b) In-line fuse/circuit breaker required: Fuse/circuit breaker

to be installed must be sized in accordance with chart
on back page. Do NOT install a GFI (Ground Fault
Interrupter) to this equipment (per article 210-8 in the
National Electric Code).

c) Route power supply cable to the location where the

Steam Generator will be installed (before walls are
closed).

2. Electrical Rough-in

a) Route appropriate power cable to the location the Steam

Generator will be installed. If receptacle is desired,
mount the box for the receptacle near the location of
the Steam Generator.

NOTE: The plug and receptacle require a rating of no

less than 250V and proper amperage. Refer to chart on
page 4 for amperage rating.

After the walls are complete, the Steam Generator and

Control can be wired.

3. Steam Generator Electrical Installation

WARNING: All power to the Steam Generator must be

turned off.

a) Remove the four screws holding the electrical access

cover and remove cover.

b) Locate the supply line knockout. Mount proper strain

relief into knockout hole.

Model: TSG-12 & TSG-15

c) Strip back power cable’s outer insulation jacket

eight inches and insert into Steam Generator.
Strip back insulation ½" from the three (3)
incoming wires (two power and one ground).

d) Insert ground wire into grounding lug located

on the right side of the electrical compartment
and secure.

CAUTION: Be sure the ground wire does not

come in contact with a live electrical part.

e) Locate the terminal/fuse block in the upper portion

of the electrical compartment. Insert power wires
into the power lugs on the front of the terminal/fuse
block and secure.

4. Optional Auto Drain Valve Connection

a) Open knockout for Auto Drain Valve conduit

connection.

b) Route flexible conduit from valve to knockout and

secure.

c) Connect two wires from valve to the auto drain

connection J8 on the printed circuit board (see
Figure 2).

WARNING: Elderly persons, pregnant women, or those suffering from heart disease, high blood pressure, diabetes, or

who are otherwise not in good health, do not use this device unless directed to do so by a physician. Also, do not use
steambath while under the influence of alcohol. For additional Important Safety Information, please see a separate

instruction sheet Pub. No. 199.

IMPORTANT: The warranty of this product is voided if it is used in a commercial application or for anything other than a residential

steambath installation. All electrical connections must be performed by a licensed electrician in accordance with Local and National
Electric Codes. This product is not intended for use with Home Automation systems.

5. Ganging Mulltiple Steam Generators

IMPORTANT: When ganging 2 to 4 steam generators

together an additional 3199 steam head and 5158 control
cable must be purchased for each additional generator.

a) Locate the Control Cable knockout at top of steam

generator. Mount proper strain relief into knockout hole.

Checklist

Before starting, insure that the conditions of the following checklist have been met:

The proper size Steam Generator has been selected by
using the sizing page in the “Full Line Brochure,” “Pricing
Guide,” or “The Generator Sizing Guide” in the Residen­tial Systems/Steambath Product Information section of
the Steamist website - www.steamist.com.

CAUTION: An improperly sized Steam Generator will

NOT produce the amount of steam necessary to reach
selected temperature.

The proper voltage Steam Generator has been selected
(i.e., 208V or 240V). A 208V Generator operating on
240V will damage the heating element, and a 240V
Generator operating on 208V will result in a 25%
loss of power.

b) Route 5158 control cable from any one of the 4 Modular

Jacks located on the circuit board to the steam genera­tor to be ganged (see Figure 3).

c) Set DIP Switches on each additional Steam Generator's

main PCB as shown in the Gangable Generators chart
(see Figure 3).

The Steam Generator is installed in an upright position.

The proper sized 90°C copper wire and circuit breaker
have been used.

The circuit breaker is NOT a GFI (Ground Fault
Interrupter) type.

The Steam Generator is properly grounded.

The circuit breaker or disconnect switch is on.

Water supply is open to the Steam Generator.

Figure 4 - Typical Installation

Steam Outlet Pipe - Use a minimum of a ¾"
Copper or Brass pipe.

CAUTION: Do NOT install a shutoff valve on the
steam outlet pipe. Do NOT create traps or valleys
in this line which would prevent the flow of steam.
The steam outlet pipe should be pitched toward
the Steam Generator (preferred), allowing conden­sation to run back into the Steam Generator or
toward the steamhead. If the steam pipe exceeds
ten feet, use an appropriate pipe insulation rated
for a minimum of 212°F.

Connect ¾" pipe to an

indirect waste or as required

by local codes.
