Installation

 

Gas Connection 

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

 

1. Waldorf Gas Griddles do not require an electrical connection, as they function totally on the gas  

supply only. 

2. 

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

supply pressure and volume is 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, 

refer to the ‘Dimensions’ section for rating plate locations 

for the different models.  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. 

 

3. 

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

 

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

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

 

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

 

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

 

 

Regulator connections are

Connection to appliance is

" BSP male. 

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

 

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

 

4. 

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

unit is level and at correct height. 

5. 

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

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

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