Ratings and Certifications
Standards:
•Gas fired hot water boiler for either direct vent installation or for installation using indoor combustion air. Design according to: ANSI Z21.13b 2007 – CSA 4.9b 2007 – Fired low pressure hot water boilers. Category IV.
•SCAQMD Rule 1146.2
All Raypak boilers are National Board Approved, and design- certified and tested by the Canadian Standards Association (CSA) for the U.S. and Canada. Each boiler is constructed in accordance with Section IV of the American Society of Mechanical Engineers (ASME) Boiler Pressure Vessel Code and bears the ASME H stamp. This boiler also complies with the latest edition of the ASHRAE 90.1 Standard.
WARNING: Altering any Raypak pressure vessel by installing replacement heat exchangers, tube bundle headers, or any ASME parts not manufactured and/or approved by Raypak will instantly void the ASME and CSA ratings of the vessel and any Raypak warranty on the vessel. Altering the ASME or CSA ratings of the vessel also violates national, state, and local approval codes.
Installations at Elevation
Rated inputs are suitable for up to 4,500 ft elevation (see technical data table). Consult the factory for installations at altitudes over 4,500 ft above sea level. No hardware changes are required to the boilers for installations up to 10,000 ft (adjustments may be required).
4 - REGULATIONS AND GUIDELINES
The installation must be 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. In Canada, installation must be in accordance with the requirements of CAN/CSA B149.1, Natural Gas and Propane Installation Code. 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
Install CO detectors per local regulations. Boiler requires yearly maintenance, see chapter “Checks, adjustments and fault finding”.
Operating Limits of the boiler: |
|
Max. boiler temperature: | 194°F (90 °C) |
Max. operating pressure: | 45 psi (3.1 bar) |
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.
