Based on maximum input and 1075 Btu/Ft.
2.
The air flow must be adjusted to obtain a temperature rise within the range shown.
3.
On VAV units, individual room damper boxes must go full open in heating mode to ensure airflow falls within temperature rise
range.
4.
For operation at elevations above 2,000 feet and, in the absence of specific recommendations from local authority having jurisdic-
tion, equipment ratings shall be reduced at the rate of 4% for each 1,000 feet above sea level.
5.
Minimum heating CFM for 699 MBH input heat is 11,700 CFM.
If a unit is to be installed on a roof curb other than
a YORK roof curb, gasketing must be applied to all
surfaces that come in contact with the unit under-
side.
If a unit is to be installed on an angle iron frame it
is recommended that it be sized to allow the bot-
tom rail to overhang to facilitate installation of con-
densate drains (see Fig. 4).
