Hi all
firstly I want to say that we are oftec reg and have 30 years exp and have posted here many times so be nice.
we were called this morning to a Grant Vortex external Eco 26. On arrival we took off the top and front casing to find soot everywhere!!!!! Customer said it was serviced last Feb.
so after stripping the boiler down we found the first baffle slightly warped and showing signs of very high heat you know what I mean! We cleaned the chamber and turbalators which were coked in crap. New nozzle checked pump pressure and smoke on 0. FGA 11.5% co2 air at 3.5 ish. Only thing we couldn't test was the stats coz we left our kbb tester behind.
Apart from the control stat being shot any ideas as to what could of caused this???? Old nozzle was correct 65/80 pump pressure 8.5
thanks
also the condense pipe that connects the heat exc to the top of the trap had basically melted off on the elbow that pushes onto the metal pipe from the heat exc!
