Actually it required removing side panels in order to find the hidden screws that held the controls on so we could get at the thermocouple screw on the gas control unit. What a faff, but the oven is working again, thanks for that. Chris

I have a tame gas engineer here to replace the oven flame failure sensor, and we need to get to behind the knobs. Unfortunately we have no service manual and there are no visible fixings that we could remove to gain access to the back of the front panel controls. Could anybody help? Chris

I think my returns join at the boiler side of the house. :-) I am going into the loft and will trace the pipes to figure out where exactly the HW joins the CH on the return Chris

I am disappointed that no one has replied. I was hoping that someone more knowledgeable than I would have some suggestions as to how I could re arrange the pipework in the loft so as to prevent the backflow convection that (I am assuming) is causing the radiators to sometimes heat up when the...

If I altered the layout to this what would be the best way in which to connect the CH with the HW system and then connect to the boiler

Existing main layout of 22mm CH pipework

I have tried to create a pipe layout just showing the main structure without showing where the radiators are. The vertical pipes one of which is illustrated as bold are running between the joists and about 50-75 mm lower than the red and blue 22mm flow and return to the radiators which...

I believe the system is balanced.... However I did it myself after having to rerun some of the pipework in the loft because of a loft conversion. I didn't know about the temperature drop, so it has all been set up by best guess. The Plumber had been told to run the pipework around the...

I have had this issue for years, and even replacing the three port valve completely did not solve it. Now with the gas prices so high I would like to get to the bottom of the issue. Could it be some sort of convection causing a reverse flow into certain radiators. I notice that about half the...

The 1000 dollar question is "How" did you fix it? Chris
