Install the Steam Line
WARNING: Risk of scalding.
Do not locate the steam head near a seat or bench. Scalding may
occur upon contact with the steam head.
NOTICE:
Never run the steam line down, then up. Running the steam line down and then up will create
a steam trapway, blocking the flow of steam. The steam line should run up to the steam head from the
steam generator, at a pitch of 3/8
″
(10 mm) to 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 1/2
″
copper tube for the steam line.
NOTE:
When possible, use 45° elbows. Performance will be increased when 45° elbows are used.
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.
