STEAM OUTLET
Connect the field steam piping to the outlet on top of boiler. See Figure 3. If a main steam
manifold is used, it should be pitched 1/4" per foot of horizontal run so that condensate
will run into a steam trap, rather than back into the boiler. All steam supplies should be
taken off the top of the manifold to prevent condensate from entering the process machines.
SAFETY VALVE
Safety valves should be piped so that they cannot discharge on people or damage prop-
erty. The discharge piping must be supported so that the weight of the piping is not trans-
mitted to the safety valve body. Refer to drawing PL-049 in the Appendix for an example
of typical safety valve piping. the weight supported by the valve outlet should not exceed
the weight of a drip pan elbow. Use only Schedule 40 pipe for discharge piping.
DO NOT
USE Schedule 80, extra strong, or double extra strong discharge pipe or connections.
Installations requiring long discharge piping should not be connected directly to the safe-
ty valve.
During installation, be sure that pipe compound or tape is used only on external threads
and that the inlet of the valve is free of any foreign material.
DO NOT USE A PIPE WRENCH
when working on the safety valve. use only the proper type
and size wrench.
WARNING: NEVER REDUCE THE INLET OR OUTLET SIZE OF THE SAFETY VALVE;
NEVER HANG PIPING ON THE SAFETY VALVE;
NEVER INSTALL VALVES(S) IN THE SAFETY VALVE PIPING;
NEVER PLUG THE BONNET VENT. SERIOUS DAMAGE OR INJURY
COULD RESULT FROM THE FAILURE OF THE SAFETY VALVE.
BLOWDOWN PIPING
Connect the boiler, the Warrick Low Water cut Off, and sight glass blowdown lines in
accordance with local code requirements. See Figure 4. the blowdown must be piped to
a safe place of discharge to prevent injury to personnel or property damage.
It is recommended that a blowdown tank be used to safely discharge the blowdown into
the sewers. Check state and local codes concerning the maximum allowable temperature
for blowdown entering public sewer systems.
All valves, piping, and forged fittings used n the blow-down lines shall be, of suitable rat-
ing, and in accordance with ASME Code B31-Power Piping. All pipe nipples used shall
be Schedule 80 pipe.
WARNING: NEVER REDUCE THE VENT SIZE OF THE BLOWDOWN TANK.
To properly and safely blow down the boiler, the vent must be piped full size for the entire
length, and must terminate at a safe place of discharge per local codes.
