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 lbs/hr (1GPM) and 2,000 lbs/hr (4 GPM) with 65° 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
· Ratings based on active length. Difference between active and
total length is approximately 2". Aluminum fins are 2-1/8" x 2-¾"
x .008" thick, spaced 60 per foot (unpainted)
· All hot water ratings shown in this table determined in
conformance with I=B=R code, and said ratings have been approved by the I=B=R
Baseboard Rating committee.
