Install the Steam Line
WARNING: Risk of scalding. Do not block the steam head or locate the steam head near a seat or bench, as the
steam head is hot during operation and may scald the user.
NOTICE: Do not install the slope of the steam line down, then up. If the slope of the steam line is down and then up, the
steam will be trapped and block the flow of steam. Install the steam line at an incline to the steam head, at a pitch of 3/8"
(10 mm) - 1/2" (13 mm) per 12" (305 mm) of pipe.
NOTICE: Provide clearance between the back wall and the elbow leading into the steam housing. The elbow must not
contact any wall material.
NOTICE: Provide clearance between the steam line and surrounding surfaces.
NOTICE: Do not apply excessive heat to the generator connections when you solder connections. Do not apply flux or
acids directly to the steam generator, as damage to the seals, plastic components, and trim finish may result. Do not apply
petroleum-based lubricants to the steam generator components, as damage may result.
NOTE: Use thread sealant tape or pipe sealant for threaded connections. Do not overtighten the fittings.
NOTE: Use a 1/2" copper tube for the steam line.
NOTE: For optimum performance, use 45° elbows in the steam line when possible. The use of 90° elbows may result in an
increase of condensation in the steam line.
NOTE: Always install a union fitting (supplied) as close as possible to the steam generator.
Add blocking behind the desired steam head location.
Install and secure a 1/2 NPT elbow to the blocking directly behind the desired steam head location.
Install a temporary 1/2" copper nipple that extends through the finished wall.
