do you have to take exterior cover of ?

You are disconnecting a gas seal so first switch the gas off. If your in any doubt, get a competent person to do this for you

To remove the burner module first remove the outer plastic cover and the inner aluminium plate under that. This will expose the burner and gas valve to it's the right, in  the bottom right hand corner under the gas valve you will find two 'cross-head' Pozi-drive screws looking at you, unscrew these and the module pulls out.

It may not want to come and this means the black box lid inside the van has popped open, you will need to go inside an squeeze it shut while pushing to get it started through the hole. Once out you can un-plug it and replace with the new one.

Lastly and importantly, as it's held on the right, it will hang to the left, before final tightening of the screws then,  you will need to lift the left hand end of the burner a little to make sure the bracket and seal at the back is as high as it can go and parallel to the recess in which it fits.

Finish tightening the screws, switch on the gas and test briefly, (no more than 30seconds), without replacing the covers, after gas has come through, make sure it lights more or less instantly and burns with a bright blue flame. Any orange flecks in a blue flame is normal and will soon reduce, any yellow lasy flame is incorrect albeit the wind will cause this without the covers so for test purposes protect the flame with a suitable shield.

thanks very much as you was replying to me i took the covers of. typical been a mechanic all my tools are at work including my no.2 pozi drive screw driver and dont wat to risk rounding them with a phillips lol . i am comftable with working with gas as i do it all the time on lpg converted cars (not a daft lad lol ) so thats the job off for  another night as a trip to work costs me £5.40 in toll charges on the humber bridge . many thanks lee
