Appendix E – Installation and Quick Reference
Fuel/Gas Supply

Refer to 3.7 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:
Natural Gas
Minimum Inlet Pressure = 3.5
Maximum Inlet Pressure = 14.0"
NOTE: 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:
Model
Number
ST-2500
ST-3000
ST-3500
ST-4000
ST-5000
ST-6000
ST-8000

Prior to startup, carefully check all electrical connections for tightness as connections can come
lose during shipping.
