Fluing To comply with the requirements of AS5601 the LHEC30 gas fireplace and RFSDV34 gas log fire must be flued. The LHEC30 is certified for a minimum flue length of 3.7 m and a maximum flue length of 10.7m whilst the RFSDV34 is certified for a minimum flue length of 3m and a maximum flue length of 12m.
Wiring Diagrams Wiring Diagram – LHEC30 & RFSDV34 When installing the RFSDV34 the draught hood adapter (draught diverter) supplied with the log fire MUST be installed. The draught diverter has an inbuilt „blocked flue safety switch‟ which MUST be wired in series with thermopile circuit 1 by the installing technician. The log fire must not be operated unless the draught diverter is installed and the blocked flue switch wired as per the installation instructions & wiring diagram shown below.
Components and Their Function Transformer The transformer converts the incoming supply voltage from 240 VAC to 115VAC. Fan The fan moves air from outside the log fire through the back of the heater and out through the front louvre via an air flow chamber. The air flow chamber is separated from the combustion chamber and is heated by conduction. The heated air is then circulated by the fan (convection heating).
The burner manifold directs gas from the gas valve to the front and rear burner injectors. The burner manifold has an aeration shutter which controls the air gas ratio for delivery to the injectors. The aeration shutter is preset and the position remains the same for both gas types. Injectors Both log fires have three injectors (pilot, burner front and burner rear). The pilot injector delivers gas to the pilot whilst the burner injectors deliver gas from the burner manifold to the burner for combustion.
6. Antenna: The antenna receives transmissions from the remote control. The antenna should hang in free air away from grounded (earthed) metal. 7. Gas type plug: There are two gas type plugs available, one for NG and one for Propane. This plug determines the gas type the gas valve operates on (refer to „Gas Type Conversion Procedure‟ on page 51 for more information). 8. Pilot adjustment screw: This screw is utilised to adjust the pilot flame height by altering the gas pressure to the pilot.
6. After successful ignition the pilotstat knob (4) is then manually turned to the „ON‟ position allowing gas entry via the gas valves (2) internal main valve to the burner (11). The burner (11) and fan (12) will now operate on full flame and full speed and both the internal pilot valve solenoid and internal main valve solenoid are held open by the voltage generated by thermopile 1 (8) and thermopile 2 (9), provided the blocked flue switch (10) remains closed. 7.

Lighting Instructions 1. Ensure the LOCAL/REMOTE selector switch on the gas valve is set on LOCAL. 2. Remove the log fire glass door. 3. Turn the pilotstat knob to the PILOT position, push the pilotstat knob down and hold it in the depressed position. The pilot valve is now open and will allow gas to flow to the pilot. 4. Push and release the piezo igniter until the pilot flame is established.
On (Manual) Mode Press and release the „Mode‟ button until „On‟ is displayed on the controller. After a two second delay the burner and fan will turn on and operate on the previously used settings. The information shown on the diagram opposite will be displayed on the remote controller display. To adjust the main burner flame level press and release the flame button. The flame icon will be displayed along with the current flame level setting.
If the set point temperature is now higher than the room temperature the optimum flame and fan levels will automatically be selected to reach or maintain the set point temperature. These levels (of modulation) will depend upon the differential between the set point temperature and the room temperature i.e. larger differential = higher flame and fan levels. For example: If there is a differential of 2.
Preventative Maintenance It is suggested for peak performance that the log fire be serviced annually. Servicing is to be performed by qualified persons. 1. Remove log set and larva rocks. 2. Clean the glass panel(s) with a non-ammonia based household cleaner and warm water (gas fireplace glass cleaner is recommended for use as a cleaning agent). Check the glass and gasket for cracks or damage and replace the glass frame assembly and/or gasket if necessary.
Common Faults When a complaint is lodged about the performance of a gas fireplace or gas log fire there are a number of causes that should be checked and eliminated. In an attempt to pinpoint the most likely cause it is important to discuss with the customer their reasons for the complaint, the duration of the problem, any change in circumstances or usage and recent weather conditions.
Fan Speed or Flame Height Cannot be Adjusted by Remote Controller If the fan speed and flame height cannot be adjusted by the remote controller check the following: 1. Ensure the three pin plug is plugged in and power is available at the power point. Without power the log fire can still be lit and the burner will operate on high flame, however the fan will not operate and flame height cannot be adjusted utilising the remote controller. 2.
Adjusting the Pilot Flame When lit, the pilot should produce a flame 10 – 13mm vertically high that impinges evenly across both thermopiles. The pilot flame can be adjusted by rotating the pilot adjustment screw on the gas valve which will alter the gas pressure to the pilot. Unscrew and remove the outer cap and turn the internal screw clockwise to decrease the pilot flame or anti-clockwise to increase the pilot flame.
Error Code 3 Error code 3 is a thermopile related fault and is indicated by three 0.5 second flashes separated by a 30 second off period between each series of flashes. If this fault occurs check the following: 1. Disconnect power and ensure all thermopile spade connectors are pushed on firmly and are making contact. Check blocked flue switch to ensure it is not open circuit. Restore power. If error code 3 is still displayed move on to step 2. 2.
