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 mounting bracket is level.

Mounting Bracket WARNING: Maintain minimum clearances shown in Figure 8, page 9. If you can, provide greater clear- ances from floor and joining wall.
