OPERATION
Figure 1
The manual controls for the Log Grate are located in the
front right side. (Figure 1)
A. On/Off Switch
Supplies power to the Log Grate.
B. Momentary Button
Pressing this button toggles between Logs; Logs and
Flame Effect; and Off.
Remote Control
The unit is supplied with a radio frequency remote control.
This remote control has a range of approximately 50’
(15.25m). It does not have to be pointed at the replace
and can pass through most obstacles (including walls).
It is supplied with one of 243 independent frequencies
to prevent interference with other units. The frequency
designation is indicated on the back of the remote control.
!NOTE: Before attempting any operation with the remote
control, pull the plastic insulator strip out from between the
remote casing and battery cover (Figure 2).
Remote Control Initialization/ Reprogramming
Follow these steps for remote control initialization and if
required, re-initialization:
1. Unplug power adapter from unit.
2. Wait a minimum of ve (5) seconds and then plug
power adapter back into unit.
3. Within 10 seconds of re-acquiring power, press the ON
button located on the remote control. (Figure 2)
This will synchronize the remote control and receiver.
Remote Control Usage
Pressing the On button, on the remote control, switches
between the two levels:
Level 1: The logs and lights are turned on.
Level 2: The logs and lights remain on and the ame
effect is activated.
The replace can be turned off at any point by pressing the
Off button on the remote control.

MAINTENANCE
WARNING: Disconnect power before attempting any
maintenance or cleaning to reduce the risk of re, elec-
tric shock or damage to persons.
Log Grate Surface Cleaning
Use a warm damp cloth only to clean surfaces of the Log
Grate. Do not use abrasive cleaners.
Water Reservoir
!NOTE: There is no need to remove any of the logs
or move the unit to access the water storage system.
However if you decide to move the unit to perform cleaning
ensure that the logs are stable before moving.
The water storage system is located behind the back log.
It can easily be removed by lifting each of the components
directly up. (Figure 3)
!NOTE: There are tabs, on each end, that need to be
turned to release the components.
CAUTION: It is strongly recommended that Distilled
water or softened water be used in the unit to prevent
scaling of the components.
If you do not intend on using the unit for longer than 2
weeks, empty and drain the unit of water, and dry all of the
water containing components.
It is recommended that all of the water containing
components are cleaned with soap and water on a
biweekly basis. A small brush has been included to assist
in cleaning difcult items/areas, i.e. the transducer.
CAUTION: Do not put plastic components in the
dishwasher.
!NOTE: If you need to move the unit ensure that all of
the components that contain water have been emptied
before relocating.
