Methods For Attaching Mounting Bracket 
To Wall

Only use last hole on each end of mounting 
bracket to attach bracket to wall. These two 
holes are 14 inches apart from their centers. 
Attach  mounting  bracket  to  wall  in  one  of 
two ways:
1.  Attaching to wall stud
2.  Attaching to wall anchor

Attaching to Wall Stud:

 This method provides 

the  strongest  hold.  Insert  mounting  screws 
through  mounting  bracket  and  into  wall 
studs.

Attaching to Wall Anchor:

 This method allows 

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

Marking Screw Locations

1.  Tape  mounting  bracket  to  wall  where 

heater will be located. Make sure mount

-

ing bracket is level.

  WARNING:  Maintain  mini-

mum clearances shown in Figure 

8, page 10. If you can, provide 

greater  clearances  from  floor 

and joining wall.
