1.2.7 Fasten the heater to the duct with sheet metal screws and seal openings with a suitable sealing compound.
1.2.8 If the heater is heavy, use additional hangers to support the heater.
1.2.9 Flange both ends of the duct outwards on three sides to match the heater's fl anges.

(Please see drawings page 4).
Note: Distances may vary for heaters installed in air handling units (AHU).
• 24 inches between the heater and fi lter frames.
** inches between the heater and elbows in the duct.
** inches between the heater and branches in the duct.
** inches between the heater and sharp transitions of the duct.
** = minimum distance = the largest of two dimensions (W or H) up to 48".
Examples:
• 48 inches between the heater and a double outlet fan, except with split duct design.
•30 inches between the heater and access doors or diffusers, except if a metal screen is supplied with the heater.
• 1 inch between the duct at the outlet side and combustible materials for a length of 72", for vertical ducts only.
• For the fl anged type, 24 inches between the control box cover and obstructions to allow space for installation and
service.
• For the slip-in type, width of the duct (dimension W) + depth of the control box + ten (10) inches between the
control box cover and obstructions to allow slipping the heater out the duct and to allow safe servicing.
