REMOTE CONTROL GENERAL LAYOUT
• Use 2 x 1.5V AAA batteries. NEVER mix old and new batteries.
• Remove batteries if the remote control is not going to be used for a long
period. This will help avoid damage from leaking batteries.
• When using Timers press Override to activate remote control functions.
• If the heater is operating in Override mode, using the STANDBY/ON button will
cancel any future timer operations, these will have to be reset manually.
• Some fluorescent lights may interfere with the transmission of remote control
signals, in this case changing the position from which you are operating the
remote control may help.
• Avoid leaving the remote control in direct sunlight and do not place it close to
the warm air discharge louvres of the heater.
• Avoid dropping the remote control or getting it wet.

FEATURES
UNPACKING THE APPLIANCE:
Check for damage and missing parts. If the heater is damaged or missing any parts, contact your
supplier for advice. Before installing the appliance, check it is labelled for the correct gas type (see
label on top rear of heater). Refer to local gas authority for confirmation of gas type if you are in doubt.
• Room Sealed: Air for combustion is taken from the outside and the flue products are exhausted
to the outside. This means heater operation has no effect on the composition and quality of air in
the room.
• Push Button Ignition: Only one touch of the STANDBY/ON switch is all that is required to
operate the heater.
• Lock: When the Lock function is activated all controls other than the STANDBY/ON switch will
be locked. Deactivating the lock releases the controls. If the lock is activated when the appliance
is in STANDBY, all functions will be locked.
• Memory: The heaters micro-computer records preset temperatures, timer programming, and
operational modes. Even in the event of a power failure, the need for reprogramming is minimised.
• Dual Timer: The Dual Timer allows you to program the appliance to operate for two separate
periods each day. Once programmed the heater can then be controlled by selection of the Timer
1 and or Timer 2 functions.
The Dual Timer feature means that you can "Set and Forget" your heater. It will turn itself ON
or to STANDBY at the times you have programmed until you cancel the Timer program.
• Pre-Heat: This function automatically operates the appliance before the programmed ON time of
the Timer, in order to heat a room to the pre-set temperature by the programmed ON time.
• Remote Control: Full function cordless remote for the convenience of operating the heater from
a distance.
• Extra Low Function: The Extra low function is an energy saving feature designed to control the
room temperature economically. If the room temperature continues to rise above the set
temperature on thermostat the main burner will turn down to its lowest setting. When the room
temperature requires further heating the heater will automatically re-ignite to warm the room.
