ELECTRIC HEATER CAPACITY BTUH
FORMULAS:
Heating Output = KW x 3.413 x Corr. Factor
Actual CFM = CFM (from table) x Corr. Factor
BTUH = KW x 3.413
BTUH = CFM x 1.08 x Temperature Rise (T)
CFM = KW x 3.413
1.08 x T
T = BTUH
CFM x 1.08
CHECKING HEATER FUSE LINK
(OPTIONAL ELECTRIC HEATERS)
Each individual heater element is protected with a one time
fuse link which is connected in series with the element. The
fuse link will open at approximately 333°.
WARNING
Disconnect power supply before servicing.
4. Remove heater element assembly so as to expose
fuse link.
5. Using an ohmmeter, test across the fuse link for con-
tinuity - no reading indicates the link is open. Replace
as necessary.
NOTE:
The link is designed to open at approximately 333°F.
DO NOT WIRE AROUND - determine reason for failure.
