Installation Guide
•  Verify power has been turned o before starting any work! 
•  The Register model RM can only be mounted with the element up. It cannot be mounted in the 
ceiling. For multiple heater wiring, see page 6. 
•  For cleaner performance and longer heater life, install your heater 12 inches from the floor.
•  All models can be installed to be Americans with Disabilities Act (ADA) compliant. Check your 
state and local requirements.
•  A thermostat is required for all models. An electronic wall thermostat is recommended for ultimate 
comfort and energy savings. 
•  The wall can label arrow shows the correct mounting orientation (arrow must point up). 
If you haven’t installed drywall yet, make sure the front of the wall can extends beyond the front edge 
of the wall stud to match the drywall depth (Figure 2). 
If you already have drywall installed, rotate the wall can into the cutout legs first. Keep the front of the 
wall can flush with the drywall. 
Fasten the wall can to a stud (on either left or right side), with two screws (not included) through the 
larger holes provided in the wall can (Figure 2). 
tip: if not installing at minimum height, for additional support in new construction, legs can bend 90 
degrees on the wall can (see Figure 2).
