    Sounds like...

    an air/fuel adjustment to me. I'm not familiar with that particular product, but regardless, if the air fuel ratio is wrong, it will have issues lighting off.

    You MUST use a combustion analyzer to figure it out. Even if you get it to light off smoothly, you could be producing too much still be producing excess CO.

    I'd recommend starting at the factory level and moving up from there. They have THE most experience with the product.
