Electric Draft Barrier Features
How To Designate A Model
NOTE:
• Extended enclosures and
Blank Sections are NOT
punched. When a Control
Section is specified,ALWAYS
allow for an extended
enclosure to compensate for
the 6” or 12” length of the
Section required.
• Note on order when finished
backs are required and add
list adder to model list.
•
Total heater amperage must
notexceedthe25-Amprating
of the high temperature limit
at any voltage or wattage.
This applies to all Sill Line
Model Series.
*Units with Extended Enclosures may require more Pedestals than standard length, must verify length of heater after extended enclosures for
total amount of pedestals. NOTE: All bottom inlet units must be mounted a minimum of 3 inches above finished floor.
Dual element models DBCT/DBCF and ASHDB. All elements are single phase. Consult factory for more information.
