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.
If so advised by the responsible agency, the installation must satisfy the
requirements of the standard for Controls and Safety Devices for.
Automatically Fired Boilers, ANSI/ASME CSD-1.
Install CO detectors per local regulations. Wall-mounted gas condensing
boilers require yearly maintenance ( Chapter 15, page 65).

Maximum boiler temperature
Maximum operating pressure
Table 9 Operating limits
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
