Wall Mounting (to Non-Combustible Wall Only)
1. Fix the wall mounting bracket to the wall with six screws,
in such a position that the top of the bracket is level and
at least 945mm (38”) above any surface beneath the unit.
This will ensure that the bottom of the Salamander is at
least 600mm (24”) above any surface.
2. Fit the two black plastic spacers to the top rear corners of
the unit. Leave them unscrewed by approximately 5mm.
3. Fit the two adjusting screws / bolts into the nutserts at the
bottom rear corners of the unit. These should protrude
approximately 30mm from the rear of the Salamander.
4. Lift the Salamander onto the wall bracket, lining up the
black plastic spacers on the salamander with the mounting
notches in the bracket.
5. Lower the Salamander onto the mounting bracket.
