Harsco Industrial SC-2000 Installation & Owner's Manual page 2

Installation and Operation Quick Reference
Fuel/Gas Supply
• Refer to Section 3.6 for information on proper sizing of the gas supply piping. Undersized gas
piping with too much pressure drop will negatively impact the boiler's performance.
• Install a lock-up type gas regulator to supply an appropriate gas pressure as described below:
Minimum Inlet Pressure = 4.0" w.c.
Maximum Inlet Pressure = 14.0" w.c.
• NOTE: Harsco Industrial, Patterson-Kelley recommends installing an individual lock-up type gas
regulator in the gas supply piping to each boiler. For installations where one master lock-up type
gas pressure regulator will service multiple boilers, Patterson-Kelley recommends contacting the
local regulator representative for application assistance specifying the appropriate lock-up type
regulator and gas pipe sizing.
Electrical/Power Supply
• Carefully inspect the boiler's nameplate labels which describe the power supply requirements.
• Provide an appropriate power feed to the boiler with overcurrent protection:
Boiler Model
SC-2000 (240V)
SC-3000 / SC-4000 (240V)
SC-3000 / SC-4000 (480V)
• NOTE: The SC-3000 & SC-4000 MUST be ordered to the correct voltage! IT IS NOT
POSSIBLE to convert an SC-3000 or SC-4000 between the 240V and 480V configurations in
the field.
• Prior to startup, carefully check all electrical connections for tightness as
connections can come lose during shipping.
Exhaust Venting
• The P-K SONIC boilers are dual-certified as Category II & Category IV appliances,
capable of operating with slightly negative to slightly positive exhaust pressure. It is
critical to ensure the flue venting material is suitable for use with the boiler.
• For Category II installations, ensure the flue venting system is designed to maintain
a slightly negative exhaust pressure which does not exceed -0.04" w.c.
• For Category IV installations, ensure the flue venting system is designed to maintain
a slightly positive exhaust pressure which does not exceed +0.22" w.c.
