Measure the height of the radiator.2. Count the number of columns in a section.3. Count the number of sections.4. Multiply the total number of sections by the number of.. .. . square feet per section as shown in the following tables:Column Type RadiatorsHeight(inches)131618202223263238454-1/2" WOneColumn———1-1/2—1-2/322-1/23—Sq.
