Note:
If the calculated water ow rate through a baseboard unit in a completely designed hot water heating system is greater than the standard ow rate
(1 GPM), the rating of that unit may be increased by multiplying the standard rating at 1 GPM by the factor shown for the calculated ow rate.

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 1 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.
