Burner Problem gas fired boiler

[turbo65]

Hello guys,

I m using 8t/h natural gas fired boiler with echo flame burner(Italy) . I m facing problems with its electro hydraulic valve mounted on gas train assembly. This is modulating type burner and valve is SKP70 type. We are unable to adjust the valve at start up , once the boiler starts then it is OK. Does any one else has expierience on this valve.

thanks for any advise
