Backup Batteries; Operating During Power Outages - Mendota DT3-PF2-LX Operating Instructions Manual

Backup Batteries

Backup Batteries are to be installed in the Battery Pack located on the right side of the Courtesy Panel beneath the glass
frame. The life span of the backup batteries depends on the quality of the batteries used and how long the batteries have
been installed in the Battery Pack. With good quality batteries, you can expect proper operation for periods in excess of 2
weeks.
These batteries are only utilized during power outages. Replace these batteries every heating season even if you have not
experienced any power outages. Batteries drain slowly even when not in use. This is a normal characteristic of all batter-
ies. To prevent the batteries from bleeding while not in use, you may choose to remove the backup batteries and install
them only when they are needed.

OPERATING DURING POWER OUTAGES

This electronic ignition system utilizes the supplied 120VAC power when it is available for all functions of this system. If the
AC power is interrupted during a power outage, this system utilizes the batteries (installed in the Battery Pack) as back-up
batteries. During the power outage, the appliance's burners will function. In addition, Flame Height adjustment and Sec-
ondary Burner ON/OFF functions will be available. The Fan and Accent Light, which are wholly dependent on 110VAC
power, will not function.
The fireplace is designed to operate during power outages for 1-1/2 continuous hours, Maximum. The blower will not op-
erate, but natural convection can be improved by removing the upper grill and opening the screen doors (depending on the
type of optional front installed). After 1-1/2 continuous hours of operation, during the power outage, turn off the burners for
1 hour and allow the fireplace to cool down. Consecutive 1-1/2 hour burn and 1 hour cool down cycles are allowed.
