GENERAL INFORMATION

1.13 Regulations and Guidelines

9
NOTE: Observe all rules, regulations, standards and guidelines
applicable to the installation and operation of this appliance
in your country.
9
NOTE: Valves external to the boiler must be fitted with T-han-
dles and condensate piping must be installed in accordance
with the local plumbing code.

1.13.1 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,
and/or Natural Gas and Propane Installation Code, CAN/CSA B149.1.
This 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 Boil-
ers.
Other confirmed approvals and certifications are indicated by la-
bels on the boiler.
Where required by the authority having jurisdiction, the installa-
tion must conform to the Standard for Controls and Safety Devices
for Automatically Fired Boilers, ANSI/ASME CSD-1.
Install CO detectors per local regulations. The use of a carbon
monoxide detector in conjunction with the
ucts is required. When installing a carbon monoxide detector,
the manufacturer's instructions of the carbon monoxide detector
must be followed in their entirety. It is recommended to use a
carbon monoxide detector in compliance with a nationally rec-
ognized standard such as ANSI/UL 2034-2002 in the United States
and CSA 6.19-01 in Canada. Boiler requires yearly maintenance (see
section "Maintenance")

1.13.2 Operating limits of the boiler

The heat exchanger has been designed and certified in accor-
dance 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 im-
portant to check the condition of the entire hot water heating dis-
tribution 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.
