Rough-In
IV. Rough-In:
A) Plumbing Rough-In:
The heavy Commercial “HC” Steam Generator requires
the following connections: 1/2" NPT piping for the water
inlet, 3/4" copper tubing for each steam outlet, and 3/4"
NPT safety valve should be piped to an indirect waste
line. A 1” drain line for an optional auto blow down
assembly must be piped to an indirect waste.
IMPORTANT:
The Optional Auto Blow Down feature
can dump a few gallons of boiling water down the drain
and potentially damage the plumbing. It may be
necessary to drain into an ASME Blowdown Tank
(Available as an option from Steamist) depending on
the requirements of plumbing system and local codes.
1) Rough-in a
½
" water line from a cold water supply.
Provide a local shut-off valve.
2) Rough-in the steam line using 3/4" copper tubing. Do
NOT use iron or galvanized pipe, it will rust and
discolor wall of steam room. For a steam line that is
longer than 10 feet use an appropriate pipe insula-
tion rated for a minimum of 250ºF. The steam head
should be located approximately 18" above the floor
and as far from the bather as possible. Do NOT
install shut-off valves in this line. Do NOT create
traps or valleys in this line which would trap conden-
sation and block the flow of steam.
3) Rough-in a 1” drain line for a manual drain or an
optional auto blow down assembly and provide for
an indirect waste, to be used for draining steam
generator.The indirect drain must be in accordance
with local plumbing codes.
4) Rough-in a drain line using
¾
" pipe routed to an
indirect waste from the Safety Relief valve. The
discharge end of this pipe must NOT be restricted in
any way. It must be piped in a way that would safely
discharge steam and/or boiling water in the event of
a failure. Always follow local plumbing codes.
B) Electrical Rough-in:
1) Route power supply cable to the location where the
steam generator will be installed.
2) Route control cables as described in the Digital
Command Center.
Models: HC-9 thru HC-24 with DCCP Control
