Hi . I just serviced a Boulters Camray 5 150/200. I always first run it for a minute to check if it starts ok etc before I start and sounded ok.
Quite a bit of carbon on the baffles, just presumed not seen a service in years. Nozzle and blast tube looked ok.
Written in marker on the side panel was the nozzle (1.25x 60 x W) @ 165 psi set up.
So after cleaning all out replaced the nozzle with same and checked pressure and just under 170psi. Adjusted back to 165 and All sounded ok.. Done smoke test and then combustion test - 11.7%co2 co5ppm 32.2 Ex air, 95.3% efficient ..External Flue temp 114deg C ?? Waited a bit but stayed at that and boiler up to temp. I thought this a bit low for such a big boiler. What s the chances of it condensing (Camray - non condenser) and corrodeing . ?
Looking tonight at old manuals of similar Btu boilers looks like the nozzle is under sized and the high psi is trying to make up for it ?
Does any one have a manual for this Camray 5 150/200 . should I go back and change it.? To what? Client says house is fine and warm.
