    Oil smell

    The only explanation for the oil smell would be intermittent delayed ignition. Some anti-drip devices require higher pump pressures if they are a check valves. They don't really solve any problems. Most after-drip is caused by air in the head of the nozzle, not behind it. Ran tests on every device for six months and none of them worked unless you had a defective pump and that ain't the fix. 100psi is marginal pressure. Nozzle should be down sized one size and 125-130psi should be used. Get rid of drip device, they only cause additional problems. Hopefully you are using an 80 degree, solid nozzle. CO test could be helpful in solving real problem.

    oil smell

    the new cad cell controls from carlin do a great job of pre purge/post purge with 15sec. safeties we use these on tight sectioned boilers, long chimney runs or turns or cold start boilers you can pick post purge times as an option
