Appendix D – Installation and Quick Reference
Fuel/Gas Supply
Refer to
Section 3.6 Piping
•
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:
•
Natural Gas
Minimum Inlet Pressure = 4.0"
Maximum Inlet Pressure = 14.0"
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-1500 / SC-2000 (240V)
SC-3000 / SC-4000 (240V)
SC-3000 / SC-4000 (480V)
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

•
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"
For Category IV installations, ensure the flue venting system is designed to maintain a slightly positive
•
exhaust pressure which does not exceed +0.22"
