Battery Installation
Batteries are used for remote operation and as a backup in case of a power outage.
For the Receiver: Install four double A batteries by removing the outer cover plate (if present), and the inner
cover as shown in Figure 3929. Install batteries. For normal operation using the remote transmitter, place the
selection switch in the center “REMOTE” position. In case of a power outage, the heater can be turned off
and on manually using the same selection switch. The program button (PRG) is found here as well.
The remote transmitter requires three triple A batteries inserted under the cover located on the bottom of the
unit (Figure 40).
