Note: If the calculated water flow rate through a baseboard unit in a completely designed hot water heat-ing system is greater than the standard flow 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 flow rate.

* Ratings at 140°F and lower temperatures determined by multiplying 150°F rating by the applicable reduction factor.All the above 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 3 for two flow rates: 1 GPM and 4 GPM. The use of 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 ratings at the standard flow rate of 1 GPM must be used.
