Steam Ratings
Steam ratings are expressed in BTU per hour per lineal foot of active-
length, based on steam or 215

F, 1 PSI, (101.5
o
C) and 65

ecommended Installed Height
Ratings include the factor shown in Table 3 for the recommended installed
height. If the unit is to be installed at a height other than that recommend-
ed, the rating must be adjusted as follows:
Example for installed heights other than recommended
(example based on Multi/Pak 95-10):

† Use the values in Table 3 below for both the “RECOMMENDED
HEIGHT” factors and for the “ACTUAL HEIGHT” factors.
Dampers
Dampers are a
v
ailab
le as options on most enclosures, and are
shown in diagrams wherever applicable. Ratings are for enclo-
sures without dampers, or with dampers in fully open position.
Water Content
Slant/Fin commercial r
adiation elements contain the follo
wing
volume of water:

NOTE:
All ratings have been determined in the Slant/Fin Environmental Laboratory in
conformance with accepted industry practice concerning testing and rating
procedures f

ratings indicated. Use of material or installation methods other than those
specified by Slant/Fin may result in a change in the ratings.

Water Ratings And Flow Rates
The hot water ratings shown in this catalog are based on the following
Water velocity: 3 or more feet per second
Entering air temp: 65
o
Steam temperature: 215
o
Proceed as follows to determine output under conditions
different than above:
Water velocity less than 3 feet per second: multiply
the hot water ratings by the factors shown in Table 1.

The installed height for
enclosures is defined as
the distance from the fin-
ished floor to the center of
the outlet.
Recommended
