Model Identification
The model identification number and boiler serial num-
ber are found on the rating plate located on the inside
upper right panel and also on inlet air decal. The
model number has the form H7-198AR or similar
depending on the unit size and configuration. The let-
ter in the first group of characters identifies the
application (H = Hydronic Heating). The number which
follows identifies the firing mode (7 = electronic mod-
ulation). The second group of characters identifies the
size of the unit (three numbers representing the
approximate MBTUH input), and, where applicable, a
letter indicating the manufacturing series.
Ratings and Certifications
Standards:
•
ANSI Z21.13 · CSA 4.9 - latest edition, Gas-
Fired Hot Water Boilers
•
SCAQMD Rule 1146.2
All units are National Board Registered, and design-
certified and tested by the Canadian Standards
Association (CSA) for the U.S. and Canada. Each boil-
er is constructed in accordance with Section IV of the
American Society of Mechanical Engineers (ASME)
Boiler and Pressure Vessel Code and bears the ASME
“H” stamp. This boiler also complies with the latest edi-
tion of the ASHRAE 90.1 Standard.
Installations at Elevation
Rated inputs are suitable for up to 2,000 ft elevation
without de-rating. Consult your local representative or
the factory for installations at altitudes over 2,000 ft
above sea level. No hardware changes are required
to the boilers for installations up to 10,000 ft (adjust-
ments may be required).
