MOUNTING
1. Locate heater position on wall. This unit has special baffle plates
and vent holes in the cover to ensure sufficient convection currents.
Make sure that the heater is mounted so that the mounting label
located on the end cover points up (Fig. 1).
2. To locate mounting holes, see Specifications Table for heater in
question. In standard 16” stud center frame construction, locate
wall studding and locate 1 upper and 1 lower mounting hole in
center of stud.
3. Drill a pilot hole in metal or wood surfaces using a convenient
small size drill.
4. Drill the 4 holes in accordance with sizes in Table 1. Insert anchors
where applicable.
5. Remove cover screws.
6. Remove cover.
7. Fasten to wall with screws as listed in Table 1. Turn tight and then
back off 1/2 turn, to allow for expansion and contraction.
8. Replace heater cover — fasten with screws and washers removed
in Step 5.
