RatingsRatings
Notes: Notes:
I=B=R approved water ratings are based on the active (finned) length and
include the 15% addition for heating effect allowed by the I=B=R Testing
and Rating Code for Baseboard Type of Radiation. The active length is 3"
less than the enclosure length. Ratings apply to the assembly with the
damper installed and adjusted to the normally open position.
The heating elements are constructed of 3/4" nominal copper tubing
expanded into 1 7/8" x 2 11/32" aluminum fins, which are spaced 67 to the
foot; fin thickness is .008". Elements are unpainted.
Use of I=B=R ratings at the 4 gpm flow rate is limited to installations in
which the water flow rate through the baseboard unit is equal to or greater
than 4 gpm. Where the water flow rate is not known, the I=B=R ratings at
the standard flow rate of 1 gpm must be used. Flow rates exceeding 6
gpm should be avoided because of possible noise.
Pressure drop through Therma Trim Baseboard is 0.047" of water per
linear foot at the 1 gpm flow rate. At the 4 gpm flow rate, pressure drop is
0.525" of water per linear foot.
