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

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