Unit installation

The flame height control does not have to be re-set every time the fire is lit. It can be

kept at any position enabling the customer to use the right hand control only to ignite

the burner at the set flame height.

After checking turn the right hand knob to off. Depress the control knob partially at the

pilot position ( ), turn clockwise to off (

•

) and release the knob. If any

resistance is felt when turning, release the downward pressure on the knob before

continuing to turn.

14.3 Checking inlet pressure.

The burner aeration is non-adjustable. The appliance is preset to give the correct heat

input on Natural Gas at 20 mbar (8in w.g) inlet pressure and no further adjustment is

necessary. The burner pressure should be checked at the pressure test point located

on the inlet ‘T’ connector (See figure 31). The pressure check should be carried out

using a calibrated pressure gauge after removing the test point screw. The fire should

be alight and the left hand control knob at its fully anticlockwise setting (Maximum

flame height). The pressure setting should be within the limits shown in section 2 of

this manual (Appliance data and efficiency). After checking the pressure, turn off the

fire, remove the pressure gauge and replace the pressure test sealing screw. Relight

the fire and test all gas joints for soundness using a suitable leak detection fluid.
