30. The Steam Safety Valve
a) Before installing, be sure that all pipes and connects have been blown clean. Pipe
compound or dope is used on external threads only. Be sure inlet of valve is free of any
foreign material.
b) Do not use a pipe wrench on flange bolts/nuts! When making installation, use proper
type and size wrench.
c) The valve can be installed in any position (the upright position is preferred) in the
connection provided on the top left side of the boiler with no unnecessary intervening
pipe. Under no circumstances should there be a shut off valve or restriction of any kind
between the safety valve and the connection provided.
d) Do not cap or plug drain hole in the side of valve body.
e) Since the purpose of this safety valve is to protect against an overpressure situation, it
will loudly discharge hot steam in doing so. Therefore, it is recommended that a
discharge pipe be securely installed and run to a safe point of disposal.
f) When a discharge pipe is used, it must be of a pipe size equal to or greater than
that of the valve outlet. Use schedule 40 discharge pipe only. Do not use schedule 80,
extra strong or double extra strong discharge pipe or connections. It must be as short and
straight as possible and so arranged as to avoid undue stress on the valve. It must have
ample provision for draining condensate at or near the valve outlet. It must terminate
freely to atmosphere with no intervening valve of any description and it must be securely
anchored and supported.
31. The Steam Pressure Gauge Assembly
a) The gauge should be facing towards the panel box and/or operator of the boiler.
b) Except as noted, each assembly or any of its component parts may be oriented, other
than as shown to provide improved operating clearances and/or view of gauge. Before
installing steam gauge on the siphon, add a small amount of water to the siphon to create
a water seal to buffer the gauge element. This must be done to prevent inaccurate
pressure readings and/or premature failure of the gauge. Install the steam gauge into the
siphon on the water column.
32. Electrical Supply
a) A wall mounted, fused disconnect sized for the unit must be provided and fitted by the
customer/contractor if a disconnect is not supplied on the panel.
b) Fuses must be sized according to motor name plates, element ratings, NEC and local
electrical codes.
c) Normal supply will be 460 volts, 3 phase, 60 Hz AC unless otherwise specified. Consult
electrical drawing for specifics relating to your equipment.
