CUSTOM GAS TRAINS
Some utilities, insurance carriers, and industrial customers have special requirement gas components on high input
devices beyond that which are normally supplied with AERCO boilers. Secondary shutoffs, high or low pressure
operators, and external regulators are typical of the requirements of gas utilities. It is mandatory that a designer or
installer comply with these requirements. AERCO assumes no liability when these requirements are not satisfied for
any location or installation. Contact your local gas utility for their specific requirements before installing AERCO
equipment. Special gas trains with a double block and bleed (DBB) configuration (formerly IRI) are available from
AERCO.
The minimum gas inlet pressure requirements for natural gas (N.G.) and propane (LPG) are as follows:
