  • Fryer burners are blowing flames out the front

    Posted by firstdayplumber on October 17, 2022 at 11:08 pm

    My Dean SR142G Gas Fryer burners are clogged again after having the unit serviced. What would be the most likely reason for this as up until a month ago the fryer had been working well for 2 years?

    You never told us what type of gas it’s on. But here are the common problems.

    Dirty or blocked flue/firetubes. Check down through the chimney with a flashlight for dropped material or carbon build-up. Also pull out the burners and look at the diffusers inside the fire tubes. If the gas pressure has changed, the mixture off, or never been properly calibrated you may have a carbon build-up. Check the edges around the front of the fire tubes to make sure they are not leaking from a crack in the tub. Lastly, make sure that the burner area has all the sides and top properly installed and the burners are installed correctly. They have to line up with the center of the fire tubes.

    I suspect that you may have had a point where the mixture was off and made carbon/soot. That would build up on the diffusers inside the fire tubes. You can clean it, but you need to recalibrate the carburetors for proper flame. That means you should check the supply and burner pressure with a manometer.

    Your model is the same as a SM-40 Frymaster without the frills. Manual here:FM-ESG35T_spm.pdf (static-pt.com)

    It’s a liquid propane fryer that was manufactured in the factory. I have since cleaned the entire fryer (tubes, flue, burners) and had a plumber come and set the gas pressure and it took only 2 days for the carbon to buildup and begin to reclog the burner. Is there anything else I should I look at?

    The burner carburetor’s must be closed to far or the orifices have something that is disturbing the vortex from pulling air.

    I forgot to mention that the environment it is in can also be creating a low O2 level. Like steam or CO2 from a lack of ventilation.
