Inconstant starting is mostly due to the differences between the way biodiesel and HHO burn. The air fuel ratio needs to be adjusted for biodiesel to maintain the proper flame size and color. The CAD cell is the safety device that shuts off the fuel when there is no flame. If the color or brightness of the flame is off, the CAD cell will shut off the flow of fuel. If you are not experienced working on furnaces, your best course of action will be to hire a furnace technician experienced with biodiesel to adjust your furnace for biodiesel.

For those experienced with working on furnaces, going to a smaller .75 GPH nozzle and adjust the flame slightly lean.
