The Steamist SMS Generator comes factory
assembled carefully wired and tested.
Warning: All electrical power should be turned OFF
when working with the steam generator
Important: The plumbing installation must conform
to local and national code of practice
1.Pre-Installation
a) Be sure that the proper size Steam Generator has
been selected by using the sizing page in the “The
Generator Sizing Guide”
CAUTION: An improperly sizes Steam Generator may
Not produce the amount of steam necessary to reach
selected temperature
b) For optimum performance, the Steam Generator
should be located as close as possible to the
Steamroom, Shower or tub enclosure using a ¾”
copper pipe (1/2” acceptable on 4.5kW) If the steam
pipe exceeds 3 meters, it should be insulated using
appropriate pipe insulation rated for minimum of 100
°C Maximum steam pipe distance should not exceed
a total of 15 liner meters.
CAUTION: Do NOT install near flammable material
such as paints, thinners, gasoline, etc.
CAUTION: Steam Generators must NOT be installed
outdoors, in moist humid areas, in areas prone to
freezing, or extreme heat such as an unventilated
attic. To do so will void the warranty.
2. Plumbing First-Fix
Plumbing rough-in is required for the water supply
and steam line; this should be completed before the
walls are closed. For operation, the “SMS” Steam
Generator requires a 15mm. copper tubing to the
fitting on the generator for water inlet and a 22mm
copper pipe for steam outlet.
a) Water Inlet –First fix a water line, (3 bar
max) to the hot or cold supply. An isolating
valve with a 15mm connection to the steam
generator is to be provided at the generator
location
b) Steam Outlet –First fix in the steam line
using a 22mm Copper tube with sweated or
compression brass fittings only. Do NOT use
plastic pipe or fittings. Do not use any push-
fit, snap-fit or anything else that is not
specifically rated for 100 °C steam. Do NOT
use Black Iron or Galvanized pipe to avoid
rust and discoloration to steam room. The
steam head location should be 300mm –
450mm above the steam room floor or
150mm above a rim of a bathtub and as far
from the seating area and user control as
possible
c) Drain Pipe –Rough in the drain pipe to an
open drain using 15mm copper pipe.
do NOT connect the drain pipe to the steam line
(If unable to connect to a drain, cap the outlet
with a ½” brass cap, cannot be left un-plumbed
or capped.)
d) Clean Outlet –Install supplied ball valve and
plumb into an open drain using 15mm
copper pipe. (If unable to connect to a
drain, cap the outlet with a ½” brass cap,
cannot be left un-plumbed or capped)
CAUTION: Do Not install a shutoff valve in the
steam line. Do NOT create traps or valleys in this
line which would trap condensation and block
the flow of steam. The steam pipe should be
pitched toward the Steam Generator allowing
condensation to run back toward the Steam
Generator (preferred), or toward the steamhead.
If the steam generator is equipped with a drain
valve, do NOT connect the drain pipe to the
steam line
