Note: Do not leave the hand-held remote in the
AUTO mode close to the replace. The radiant
heat from the replace will turn off the replace.
Ideally, place the hand-held remote in the center
of the room facing towards the replace.
Note: Do not hold the hand-held remote for
a long time. Body temperature will affect its
operation in the AUTO mode.
Safety Features
When away from home for an extended period
of time or as a child safety feature to prevent
accidental ignition of the replace, the receiver
ON/OFF/REMOTE switch should be in the
OFF position.
Auto Shutoff Feature
1. If the average room temperature exceeds 82°
Fahrenheit (28° Centigrade), the hand-held
remote control will perform a safety override
and shut the replace off. This feature is not
available in the MANU mode.
2. The receiver continuously receives signals
from the hand-held remote to control the
room temperature. If the hand-held remote
is misplaced, obstructed, or for any reason
cannot transmit to the receiver, the receiver
will shut off the replace after 8 minutes.

buttons together to turn the unit on or off.
