Gas Connection 

NOTE:  ALL GAS FITTING MUST ONLY BE CARRIED OUT BY AN QUALIFIED PERSON. 

1. 

It is essential that the gas supply is correct for the appliance to be installed and that adequate  

supply pressure and volume are available.  The following checks should therefore be made before  

installation:- 

a. 

Gas Type 

the appliance has been supplied for is shown on 

coloured stickers located above the gas connection and next 

to the rating plate.  Check that this is correct for the gas 

supply the appliance is being installed for.  The gas 
conversion procedure is detailed in this manual. 

b. 

Supply Pressure 

required for this appliance is shown in the 

'Specifications' section of this manual.  Check the gas supply 

to ensure adequate supply pressure exists. 

c. 

Input Rate 

of this appliance is stated on the Rating Plate 

and in the ‘Specifications’ section of this manual.  The input 
rate should be checked against the available gas supply line 

capacity.  

Particular note should be taken if the 

appliance is being added to an existing installation.

NOTE: It is important that adequately sized piping runs directly to the connection joint on the  

appliance with as few tees and elbows as possible to give maximum supply volume. 

2. 

Fit the gas regulator supplied, into the gas supply line as close to the appliance as possible. 

NOTE:  The gas pressure regulator provided with this appliance is convertible between Natural Gas 

and LPG as per the ‘Gas Conversion Section’ in this manual. 

Ensure the regulator is converted to the correct gas type that the appliance will operate on. 

The regulator outlet pressure is fixed ex-factory for the gas type that the  
regulator is converted to and it is NOT to be adjusted. 

The regulator connections are 

3

/

4

" BSP female. 

The connection to the appliance is 

3

/

4

" BSP male. 

(Refer to the ‘Specifications’ section for the gas supply location dimensions). 

NOTE:  A Manual Isolation Valve must be fitted to the individual appliance supply line. 

3. 

Correctly locate the appliance into its final operating position and using a spirit level, adjust the legs 

so that the unit is level and at the correct height. 

4. 

Connect the gas supply to the appliance.  A suitable jointing compound which resists the breakdown 

action of LPG must be used on every gas line connection, unless compression fittings are used. 

5. 

Check all gas connections for leakages using soapy water or other gas detecting equipment. 

6. 

Check that the gas operating pressure is as shown in the 'Specifications' section. 

NOTE:  The operating pressure is to be measured 

at the burner operating pressure test point  
outlet with one burner operating at the 
'High Flame' setting. 

7. 

Turn off the mains gas supply and bleed the gas 

out of the appliance gas lines. 

8. 

Turn on the gas supply and the appliance. 

9. 

Verify the operating pressure remains correct.
