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 hol-

low 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.

Figure 7

Attaching to Wall Stud:

For attaching mounting bracket to wall studs

1.  Drill holes at marked locations using 9/64” drill 

bit.

2.  Place mounting bracket onto wall. Line up 

holes on each end of bracket with hole drilled in 

wall.

3.  Insert mounting screws through bracket and 

into wall studs.

4.  Tighten screws until mounting bracket is firmly 

fastened to wall studs.

Attaching to Wall using Anchor:

For attaching mounting bracket to hollow walls (wall ar-

eas between studs) or solid walls (concrete or masonry)
