b) Oven burner is controlled by a two stage multifunctional control. Pressure should pause for a brief period at an 
intermediate level (oven ignition pressure) before attaining burner operating     pressure. Refer to Section 1.9 for 
these settings. If adjustment is necessary, refer to Sections 2.5.4 to 2.5.6 
c) Switch off appliance by pressing OFF button on gas control valve and turn off electricity supply at mains. Replace 
test 

p

oint screws, control panels etc. 

 

2.5.3  Checking Performance Of The Controls  

When satisfied that pressures are set correctly in accordance with Sections 2.5.1 and 2.5.2. Proceed as follows: 

Oven 

a) Light oven as detailed in User Instructions. Set thermostat at 250°C and allow oven to heat up, ensuring fan is 
operating and turning anti-clockwise when viewed from front. 
b) Turn thermostat down to lowest setting and check oven burner goes out leaving pilot burner lit. 
c) Turn thermostat knob to a high setting whereupon oven burner should re-light smoothly with little or no delay. 
d) Check fan stops and that oven burner goes out when oven doors are opened. 
e) Check operation of power switch. When OFF fan should stop and main burner is extinguished.  Pilot burner, 
however, remains lit. 
f)  Timer check. This does not turn off gas to oven but simply provides user with an audible signal that pre-set time 
has elapsed. 
g) Press oven light button, check light is operates. 

Open Top 

Light open top as detailed in User Instructions. Check ignition is smooth and without delay. Repeat this operation 
several times. 
 

2.5.4  Multifunctional Control Description 

Access to control is gained upon withdrawal of control panel. Refer to Section 3.2.1. 
This is a two stage multifunctional control which contains a number of features for effecting       adjustments. Refer 
to Figure 3. 
When supplied fitted in unit, this component is factory set and should not require adjustment. 
The following adjusters are available: 
a) Two test points are provided for measuring inlet and outlet pressures as detailed in Figure 3. For convenience, a 
further outlet pressure test point is provided in outlet immediately below control valve. 
b) Pressure adjusting screw (REG.ADJ) 
c) Pilot adjusting screw (PILOT ADJ). This screw is provided on control for adjusting flow of gas to pilot burner. The 
unit is designed to operate on full gas flow to pilot. To ensure full flow is available, turn screw fully clockwise then 
back 2 complete turns. 
d) A screw marked NO PR. This is for rendering inbuilt governor (i.e. pressure regulator)          inoperative and is 
turned when propane is used.  

Note 

On no account must the NO PR screw be in an intermediate position, i.e. it must be fully clockwise for natural gas, or 
fully anti-clockwise for Propane. 
e) A screw marked 1 STEP ADJ. This is a device enabling gas supply to burner to flow at reduced rate initially, 
automatically increasing to full rate after a brief time interval. This assists in effecting smooth ignition of the gas. The 
oven ignition pressure is detailed in Section 1.9. 
Should adjustment be necessary, refer to appropriate Sections 2.5.5 or 2.5.6. 

Note 
The gas control valve is fitted with a safety interlock. Therefore, a period of 3 minutes will elapse before it is 
possible to re-light after complete shut-down.
