3.9 Gas Connection General Information
For natural gas connections, refer to section 3.9.1. For propane gas connections, refer to
Section 3.9.2.
The gas supply connection must comply with local regulations or, if such regulations do not exist,
with the National Fuel Gas Code, ANSI Z223.1/NFPA 54.
For Canada, the gas connection must comply with local regulations or, if such regulations do not
exist, with the CAN/CSA-B149.1 - Natural Gas and Propane Installation Code.
Before installing the boiler it is recommended that all the supply piping be thoroughly cleaned in
order to remove any residual grime which could compromise the boilers correct functioning.
As a safety measure against gas leaks, AERCO recommends installing a surveillance and
protective system made up of a gas leakage detector combined with an on-off solenoid valve on
the gas supply line.
The boiler and its individual shutoff valve must be disconnected from the gas supply piping system
during any pressure testing of that system at test pressures in excess of 1/2 PSI (3.5kPa).
The boiler must be isolated from the gas supply piping system by closing its individual manual
shutoff valve during any pressure testing of the gas supply piping system at test pressures equal
to or less than 1/2 PSI (3.5 kPa).
Clause 1.34.1b.12: Provisions for combustion and ventilation air in accordance with the section
“Air for Combustion and Ventilation,” of the National Fuel Gas Code, ANSI Z223.1/NFPA 54, or
Sections 8.2, 8.3 or 8.4 of Natural Gas and Propane Installation Code, CAN/CSA B149.1, or
applicable provisions of the local building codes.
Clause 1.34.1b.21: A sediment trap must be provided upstream of the gas controls.
WARNING!
THE GAS CONNECTION MUST BE INSTALLED BY A
REGISTERED ENGINEER WHO MUST COMPLY WITH THE
REGULATIONS IN FORCE AND TO THE REQUIREMENTS
INDICATED BY THE LOCAL GAS SUPPLIER. AN INCORRECT
INSTALLATION CAN CAUSE INJURY OR DEATH TO
PERSONS, ANIMALS OR DAMAGE TO PROPERTY. THE
MANUFACTURER SHALL NOT BE HELD LIABLE FOR ANY
INJURY AND/OR DAMAGE DUE TO INAPPROPRIATE
INSTALLATION.
Do not use the boiler for another type of gas than indicated on the
identification plate of the boiler. This will cause improper functioning
and can damage the boiler. The suitable gas type for the boiler is
indicated on the packaging label and on the data plate boiler.First
check the identification plate on the boiler for the suitable gas type.
Always check the safety of the gas pipe system by means of a soap
bubble test using a leak-search spray.
