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).
