Chris, where did you get the PDF manual for the Lamborghini boiler from please?! I'm currently staying with relatives in France who have a Lambo (Fire 1 C/FR) which after a few hours of disuse, refuses to fire up - it's showing a red light at the top left which is clearly a 'fan failure' light - we don't have a manual, and I've figured we can restart the boiler by taking the bottom front cover off and pressing what appears to be a priming pump/switch. However, this is ponly a temporary fix. My assumption is that this is possibly associated with fuel temp - the outsoide temp being around -3 at the moment. Any thoughts, or a hint as to where I could find a manul, would be gratefully received!!! [quote user="chrisbooth"] Hi again, hope you dont mind me asking another question. I have manged to download a pdf file with the instructions for the Lamborghini boiler. It appears the boiler has an output of around 34kw, it is a combi bolier but we only use it to heat the radiators. the water is provided by electric on heures creuse. If I purchased new injector for 0.50gph (does this stand for gallons per hour?), is it possible for me to self fit. I am confident of being able to physically fit the part into the burner unit, but if it then needs to be adjusted it will be beyond my expertise. I am off to france on Boxing day and now you have kindly given me information I would like to use that in making the boiler more efficient Thanks again Chris [/quote]
