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. Power-fin boilers require special gas venting. Use only
the vent materials and methods specified in the Power-
fin Installation and Operation Manual.
4. Standard Power-fin boilers are equipped to operate from
sea level to 4,500 feet
only
. The boiler will de-rate by
4.5% for each 1,000 feet above sea level up to 4,500 feet.
5. High altitude Power-fin boilers are equipped to operate
from 3,000 to 5,500 feet
only
. Th
e boiler will de-rate by
2.0% for each 1,000 feet above sea level up to 5,500 feet.
Th
e operation given in this manual remains the same as
the standard boilers. A high altitude label (as shown in
FIG A.) is also affi
xed to the unit.
De-rate values are based on proper combustion
calibration and CO
2
’s adjusted to the recommended
levels.
