Insulated Duct Heater
(Type SS)
NOTE: Heaters are designed to
accommodate the insulation thickness.
Model EDHSS
(Side Slip-In, Vertical Slip-In)
Installation of the slip-in heater consists of cutting an opening in the duct approximately 1/4" larger than
the height and width of the heater element section. Insert heater and fasten to the duct using sheet
metal screws through the control enclosure. Use extreme caution in protecting the electrical compo-
nents, as metal chips lodged in the components can cause failure. Remove any metal chips that may be
located in the electrical enclosure before connecting power.
NOTE: To prevent element section from moving inside duct, angle clips, brackets, or blank offs should be
attached to frame.
Mounting electric heater
in insulated duct is the
same as described above
for SS type heaters.
