2.8 General Instructions
2.8.1
The boiler/water heater 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
0.5 psig. The unit 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 or less that 0.5 psig.
2.8.2
The boiler/water heater should be installed such that the gas ignition system components are
protected from water (dripping, spraying, rain, etc.) during appliance operation or service.
2.8.3
The boiler/water heater and its gas connection must be leak tested, before placing the boiler in
operation.
2.8.4
The boiler/water heater when installed must be electrically grounded and bonded in accordance
with the local codes or in the absence of such codes, in accordance with the National Electrical
Code, ANSI/NFPA 70.
2.8.5
The boiler/water heater should be located in an area where leakage of the tank, or connections,
will not result in damage to the area adjacent to the appliance or to the structure. When such
locations cannot be avoided, it is recommended that a suitable drain pan, that drains adequately
be installed under the boiler. The pan must not restrict air- flow.
2.8.6
The boiler should always be purged of natural gases before starting up. The operator should
also investigate and identify the cause of any trip before attempting to relight the boiler.
