The installation must conform to the requirements of the authority
having jurisdiction or, in th e absence of such re quirements, to the
National Fuel Gas Code, ANSI Z 223.1 / NFPA 54. In Canada,
installation must be in accordance with the requirements of CAN/
CGA B149.1 or 2 Installation Code for Gas Burning Appliances and
Equipment. Where required by the authority having jurisdiction, the
installation must conform to the Standard for Controls and Safety
Devices for Automatically Fired Boilers, ANSI/ASME CSD-1.
Install CO detectors per lo cal r egulations. Boiler requires yearly
Only a qualified installing contractor may carry out the installation, the
initial st art-up, the connection for fixed gas and vent gas, and
conversion to another type of gas. The hot water distribution system
must comply with the applic able codes and regulations. When
replacing an existing boiler, it is important to check the entire hot
water distribution system to insure safe operation. Maintenance and
cleaning must be carried out at least once a year by a trained service
technician. The entire installation must be tested for proper
operation. Any defects detected must be fixed immediately.
