Mounting Base Feet to Floor
1. Remove front panel (see Removing Front
Panel of Heater, page 9).
2. Position heater with base feet in desired
location. Mark holes for drilling. Remove
heater with base.
3. For carpeted floors, make a small cut with
a sharp knife at marked locations prior to
drilling. If mounting base to a wood floor,
drill 1/8" diameter hole, 3/4" deep. (Do not
use anchors in wood floors).
If mounting base to a concrete floor, drill
with 1/4" diameter concrete drill bit, 1
floor. Insert anchors completely into holes.
4. Reposition heater with base feet over
holes. Secure base to floor with wood
screws. See Figure 13.
