Electrical Installation Instructions

Steambath Generators

Model: TSG-15

The Steamist “TSG” Generator operates with a TSC control 
mounted inside and optional 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: The “TSG” Generators are designed only to work with 
the"TSC" Control.

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. Only UL rated 90°C 
wire can be used.

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 (see Figure 3).

 

    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.

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 box. Insert power wires into the 
power lugs on the back 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 two place 
terminal strip provided (see Figure 2).
