All the above ratings are based on active length, which is 3" less than total length, and
includes a 15% addition for heating eect.
Ratings: Heating capacities are listed in Table 4 for two ow rates: 1 GPM and 4 GPM. The
use of ratings at 4 GPM is limited to installations where the water ow rate through the
baseboard unit is equal to or greater than 4 GPM. Where the water ow rate through the
baseboard is not known, the ratings at the standard ow rate of 1 GPM must be used.
