The use of I=B=R Rating @ 4GPM is limited to installations where flow rate
is known to be equal to or greater than 4 GPM. If flow rate is unknown, use
1 GPM rating.
I=B=R Ratings include 15% addition to water heat capacity.
Hot water ratings shown are at the STANDARD WATER FLOW RATE of 500 lb/hr
(1GPM) and 2,000 lbs/hr (4GPM) with 65º entering air temperature.
Friction loss through Argo Baseboard unit at 1 GPM (500 lbs/hr) is 47
MIL-INCHES per foot and at 4 GPM (2000 lbs/hr) is 525 MIL-INCHES PER FOOT.
Rating base on active length. Difference between active and total length is 3".
Aluminum fins are 2 1/8" x 2 1/8" x .008" thick, spaced 51
per foot (unpainted).
All hot water ratings shown in this table determined in conformance with
I=B=R Baseboard Rating committee.
