Gas metering ring (for diameter see table below)	1	Conversion instruction manual	1
O-ring 19*2	1	Sticker gas type / gas supply pressure	2

THE APPLIANCE IS FOR USE WITH NATURAL GAS OR LPG. (Cat II 2H3P)

These instructions must be read in conjunction with the installation & servicing instructions. This conversion may only be carried out by a competent person and has to be in accordance with local or national standards that apply when

converting to another gas type.

It must NOT be attempted unless the person carrying out the conversion is equipped with a combustion analyser and is competent in its use.

ISOLATE MAINS ELECTRICAL SUPPLY AND REMOVE OUTER CASE AS SHOWN IN THE INSTALLATION, COMMISSIONING &

SERVICING INSTRUCTIONS.

Important: Do not install the appliance into a room or internal space below ground level when it is intended for use with LPG (propane – G31). This does not apply to basements that are open on at least on side.

Conversion Instructions

2 CONVERSION OF THE GAS RING

1. Switch off the electrical supply to the appliance

2. Close the gas tap on the gas supply to the appliance 3. Remove the front panel of the appliance

4. Disconnect the coupling above the gas valve and turn the gas mixing pipe backwards 5. Replace the original O-ring and the gas setting ring with the rings in the conversion set 6. Reconnect the coupling above the gas valve and open the gas tap

7. Check the gas connections for tightness/leaks

8. Switch on the electrical supply to the appliance

CAUTION

It is not possible to adjust the CO2 level at high setting.

When the CO2 level at high setting is not within the prescribed tolerance band please contact your local Daikin or Rotex dealer. For adjusting CO2 level at low setting see § 3 .

9. Apply a sticker “gas type” (2 pcs. included in the conversion set) to the nut at the upper side of the gas valve

10. Apply the second sticker “gas type” to the appliance plate (lower left corner) in such a way that the original data referring to the gas type is covered.

11. Continue with checking the CO2 setting of the boiler. See § 3 .

CAUTION

Checking the CO2 setting of the boiler must be executed with the front panel removed.

The maximum deviation of the flue gas analyser that is allowed is

± 0,3%.

During the check the installation location must not be under the influence of overor under pressure situations.

It is not possible to adjust the CO2 value at maximum power..

When the value measured at maximum power falls without the prescribed range the boiler has to be checked on gas tightness and usage of the correct components, in particular the gas ring, the insert and the fan.

When replacing parts that can affect combustion or conversion to

another gas type the CO2 setting needs to be checked.
