Steffes 3100 Serie Manuel D'installation

THIS PROCEDURE MUST BE PERFORMED BY A QUALIFIED
1. De-energize the system and remove the front painted panel.
4100/5100 SERIES ONLY: Remove the brick core sensor(s).
2. Disconnect element wiring harnesses from elements. Carefully set
the core sensors and the harnesses to the side to prevent damage.
NOTE: Inspect element lead wires. If damaged or show signs
of overheating, these terminals MUST be replaced with
a high temperature connector (Order item #1040470).
3. Remove the galvanized front panel and set it aside.
4. Starting at the bottom, carefully lift each of the insulation blankets
and drape them over the top of the system. Using a barrier
between layers of insulation will help prevent damage.
NOTE: Use face mask, gloves, and long-sleeved garments
when handling insulation materials in compliance with
generally accepted safety practices.
5. Remove front air channel. Cover blower opening to avoid debris
falling into core blower(s).
6. Remove defective elements. When elements fail, there can be
loose debris that should be removed.
7. Insert new elements between brick layers, sliding them in until
element ends embed into side cut outs of the brick cavity.
8. Install front air channel with air deflectors (arrow shaped pieces)
facing inward and narrow ends of deflectors pointing up.
9. Lower insulation blankets back in position, one at a time. Carefully
tuck bottom edge in first, then sides of insulation into edges,
corners, and around exposed portions of heating elements to
ensure maximum efficiency.
10. Re-install the galvanized front panel.
4100/5100 SERIES ONLY: Install the brick core temperature sensor(s) making sure to secure them in
place so they do not short against the painted front panel.
11. Reconnect element wiring harnesses. Element screws should be tightened to 31 inch lbs.
NOTE: Properly torque and verify connections are secure. Loose connections will fail.
12. Re-install the painted front panel and complete the Installer's Final Check-Out Procedure found in the
Owner's and Installer's Manual to ensure proper operation.
