It is suggested that, wherever possible, the steam supply line to the appliance is a
separate line from the steam source. If the appliance must be supplied from a line
supplying other appliances, the pipe sizes and pressure will have to be verified.
Further, during idle periods, when the steam in the supply line is not in use, water will
form from condensed steam in the supply line. It is advisable to prevent water
pockets from forming in the steam line and impeding the steam flow when it is
required. Therefore, the steam supply line should be installed level or run slightly
downwards towards the appliance. Install a Ball Float Trap near the appliance to
drain out water (condensed steam) from the line to assure clean dry steam to the
appliance.
EXHAUST HOOD
An exhaust system should be located directly above the boiler to exhaust steam and
heat generated by the boiler.
PLUMBING CONNECTIONS
WARNING: Plumbing connections must comply with applicable
sanitary, safety, and plumbing codes.
Water Supply Connection
The incoming cold water supply connection, at the rear of the boiler cabinet, requires
3/8" tubing and water pressure of 25 - 50 psig. A manual shut-off valve must be
provided convenient to the boiler; this valve should be open when the boiler is in
operation.
Drain Connection
The boiler drain (2" IPS) should be piped to a floor drain near the boiler. There should
be no solid drain connection; an “open gap” between the boiler and the floor drain is
required.
