ingredients and concentrations can be expected:
4 Regulations
4.1 Compliance with standards and regulations
The installation must conform to the requirements of the authority
having jurisdiction or, in the absence of such requirements, to the latest
edition of the National Fuel Gas Code, ANSI Z223.1./NFPA 54. In
Canada, installation must be in accordance with the requirements of
CAN/CSA B149.1, Natural Gas and Propane Installation Code.
This wall mounted condensing gas boiler complies in its design and
mode of operation with the American National Standard ANSI Z21.13/
CSA4.9, latest edition for Gas Fired Low Pressure Steam and Hot Water
Boilers.
Other confirmed approvals and certifications are indicated by labels on
the boiler.
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 local regulations. Boiler requires yearly
maintenance ( chapter 14, page 62).
4.2 Operating limits of the boiler
The heat exchanger has been designed and certified in accordance with
the ASME Boiler and Pressure Vessel Code, Section IV.
The hot water distribution system must comply with all applicable codes
and regulations. When replacing an existing boiler, it is important to
check the condition of the entire hot water distribution system to ensure
safe operation. Common practice calls for inspecting an existing system
in its entirety and bringing it up to code. All pipework should be properly
cleaned and flushed.
