Attaching Mounting Bracket to Wall

Use holes on each end of mounting bracket to attach 
bracket to wall. These holes are 16 inches apart. Attach 
mounting bracket to wall in one of two following ways.

1.  Attach to wall studs

2.  Attach to wall anchor

Attaching to Wall Stud:

This way is the best providing the strongest mounting in 
wood frame houses. 

Attaching to Wall Anchor: 

This way allows you to attach mounting bracket to hollow 
walls (wall areas between studs) or to solid walls (concrete 
or masonry).
Decide which way best suits your needs. Either method will 
provide a secure hold for the mounting bracket.

1.  Tape mounting bracket to wall where heater will 

be located. Make sure mounting bracket is level. 
For wall stud mounting locate one end of the 
mounting bracket over a wall stud.

WARNING:

 Maintain minimum clearances shown in 

figure 7. If you can, provide greater clearances from the 

floor and joining wall. 

2.  Mark screw locations on wall (see figure 7).
3.  Remove tape and mount bracket from wall.
