OPERATE THIS APPLIANCE PROPERLY MAY CAUSE UNDUE DAMAGE TO THE
APPLIANCE.
Operating your Jindara Derwent
The Jindara Derwent Gas log space Heater has been designed for simple operation to provide you with the highest heat
output.
PRE-OPERATION CHECKS
Prior to operating the heater, ensure that the flue terminal is
not obstructed. Furthermore, make sure there are no
combustible objects leaning against, resting on, or within
the immediate vicinity of the unit. Check that the heater‘s
main power and gas supply are connected and switched on.
OPERATING THE HEATER
The heater can be operated by two different modes,
manually or by the thermostat remote controlled
hand held device .
Manual mode: The controls are located on the right hand
side of the front lower false panel. The operation of the
buttons are as follows:
TURNING THE APPLIANCE ON (MANUAL MODE)
1. To ignite your heater press the Ignition ON/OFF Button and the heater will automatically start the ignition
sequence. After approximated 30 seconds of pre-purge the heater will ignite.
2. The heater will always start in the low heat setting and the heater will warm-up for at least 2 minutes before
automatically going to the higher flame setting.
3. The fan will not start until the heater’s firebox has reached the minimum operating temperature. In High heat
setting the fan speed will be locked in high and can not be set to medium or low speed, unless the heat setting is
changed to medium or low. (This prevents overheating the heat exchanger.) NOTE: Turning on the thermostat
remote will override the manual operation of the heater! To go back to manual operation of the heater, the
thermostat remote needs to be off for 20 minutes before the control module will not look for any more signals from
the thermostat.

Note: The Thermostat will only send an ‘On’ command if the Set Temperature is above the Room Temperature.
When the Thermostat sends an ON command, the heater starts on Low Flame with the room fan in the OFF state.
- The Flame stays on the Low setting for 1.5 – 2 minutes and will then slowly ramp up to the highest setting over a
70 second period.
- The Room Fan will remain in the OFF state until the outlet temperature exceeds 50°C, at which point the Room Fan
will start and run at a speed dependent on the temperature difference between the Thermostat’s Set temperature
and Room temperature.
MANUAL MODE - THERMOSTAT
Derwent High Efficiency Gas Log Fire
16

RF Thermostat (Continued)
MANUAL MODE - THERMOSTAT (Continued)
The Room Fan speed settings are as follows:
- Speed 1 – difference between room temp. and set temp. is 0-1°C e.g. room 20.5°C – set 21°C
- Speed 2 – difference between room temp. and set temp. is 1-2°C e.g. room 21°C – set 22°C
- Speed 3 – difference between room temp. and set temp. is 2-3°C e.g. room 22°C – set 24°C
As the Room temperature increases or decreases, the Flame level will change according to the difference between this
and the set temperature. e.g.
- Flame will be on Low when room temp. at 20.5°C and set temp. at 21°C
- Flame will be on high when room temp. at 21°C and set temp. at 24°C
- Flame will adjust to the appropriate level between these two settings when temperature difference is within this
range.
If the Room temperature rises 1°C above the Set temperature, the Flame will be switched off.
If the Flame is off and the Room temperature drops down to the Set temperature or below, the heater will initiate the
start up sequence and the Flame will be switched on again.
Whenever the Flame is on and at any level, and the Thermostat sends an OFF command, the Flame will be switched off.
The Room Fan however will continue to run at the Low fan speed until the outlet temperature drops below 40°C and
then switch off.
The flame height and fan speed are not manually adjustable. The flame height and fan speed are set by the thermostat
according to the difference between the set temperature and the room temperature.
Note: the flame can be off, or has 7 graduated settings. The fan has 3 graduated settings.
AUTOMATIC MODE - THERMOSTAT
The automatic mode allows the RF Thermostat to control the Flame and Fan according to the programmed times and
temperatures. The switch on and off sequences operate as per Manual operation detailed above.
With the thermostat on, press and release the <A/M> button until the word AUTO appears on the LCD.
– To correctly operate in automatic mode, the time and day of the week must be set.
– The thermostat will now operate according to the program set for the current time period. Programming
instructions are found on page 17.
Manually overriding the set program
At any time, the temperature or fan speed may be adjusted up or down similarly to operating in manual mode. However,
whenever the thermostat changes to a new time period, the temperature will be set automatically according to that
period’s setting.
As a safety feature, if the Room temperature goes above the Set temperature, the Flame will switch off but the Room fan
will continue operating on speed 1 for a further 3 minutes.
