Right,
I am at my wits end. Firstly I cannot find a plumber who will come and commission my new ST40 NuWay oil burner fitted to my Range Cooker. They all throw their hands up and say - ooohhhh noo, that's special, or I'm busy, or 'has it been installed by an OFTEC engineer"
Well, it hasn't. It was installed by me who happens to have installed a number of boilers over the years, including a wood burning stove that is connected to our water.
I have installed everything as per regulations; flue diameters, distance from combustibles, diameters of oil pipes, fire valves, electrical isolation etc. It has a fan flue from Exhausto. This has been installed and works with a pressure switch.
The new burner was install in the combustion chamber. Oil line purged. Pressure set to 115 pis as per instructions for the Range Cooker. air damper set to 5, as per instructions. Air inlet is room sealed outside - no blockage.
Flue is new, no blockage. Oil pipe allows oil to flow, I timed it at about 0.5 litre per minute, so way in excess of the 0.4 gph 80 nozzle. There are no air bubbles in it. The oil comes from a tank which supplies another boiler - the CH boiler. That works, and always has done, very well.
Problem. I cannot get the feck er to start. Start it up. The fan flue starts. Pressure switch then allows power to the burner once up to speed. THe burner pre-purges, oil pressure hits 115 psi, flames start, struggles for a bit, then pop goes the puff back and the lockout comes on. Try again, same thing. Pump works, solenoid works, air works. The only way I have manages to get the thing going in anyway is to turn the pressure right down - say 80psi, then lots of air and it fires but it is MAASIVELY sooty so turn off and clean the cooker out!
Boy have I struggled. Daily call to plumbers to commission it, no reponse. All they have to do is to turn up and adjust the settings and make it work. I cannot think what I have missed. The cooker manufacturer uses the fan flue all the time, so it is not too weak or strong for the cooker. I thought maybe the draught was too high and so the flame was bouncing on the nozzle, so I trimmed the fan flue right down and still not joy.
That's it. 5 weeks without hot food! Wifey is getting ****ed off. Anyone got any bright ideas what to try next. The can only be three things, oil, air and flue, unless there is something that I am missing like preying to the God Venus or something.
I can only think there must be a fan flue issue. Is it too strong? It is set to the miniumum setting which is 20 which is equivalent to 0.8 wa I think. The instrcutions say that I should set to 115psi and 5 air and this gives a slightly different reading to normal on the analyser, but I cant get the sodding thing fired up to get any blasted reading.
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaagh!
