NOTICE
Notes:
1. The ratings are based on standard test procedures
prescribed by the United States Department of Energy.
2. Net AHRI ratings are based on net installed radiation of
sufficient quantity for the requirements of the building
and nothing need be added for normal piping and pickup.
Ratings are based on a piping and pickup allowance of
1.15.
3. SYNC boilers require special gas venting. Use only
the vent materials and methods specified in the SYNC
Installation and Operation Manual.
4. Standard SYNC boilers are equipped to operate from sea
level to 4,500 feet only with no adjustments. The boiler
will de-rate by 4% for each 1,000 feet above sea level up
to 4,500 feet.
5. High altitude SYNC boilers are equipped to operate
from 3,000 to 12,000 feet only. The boiler will
de-rate by 2% for each 1,000 feet above sea level.
High altitude models are manufactured with a
different control module for altitude operation, but
the operation given in this manual remains the same as
the standard boilers. A high altitude label (as shown in
FIG. A) is also affixed to the unit.
Derate values are based on proper combustion calibration
and
CO
2
’s adjusted to the recommended levels.
6. Ratings have been confirmed by the Hydronics Section
of AHRI.
