Nozzle sprays to one side

Terry_14 Member Posts: 209
Perplexing problem. Have you removed the burner motor and blower wheel? I have found similar with pet dander and lint on wheel.

Next I would open the bottom of the chamber and check for build up both on the floor of the boiler and then check above on the section pins. I have had success with a sawzall blade to clean all passages from below.

A build up in either place will change the air pattern within and this can effect the patern

    Nozzle sprays to one side

    I was working on a weil mclain g04 beckett fired and powervented. I fired the unit before cleaning it, and noticed the nozzle spraying to one side, I cleaned the unit. Replaced nozzle reset electrodes and cleaned the endcone and inspected chamber. I also check the draft and got that down to .05 (powervented). All this and the new nozzle still sprays alittle to the left, I tried many nozzle (all within spec of boiler)and the same thing happened. Also I use wrenches not a nozzle wrench. Any thoughts???
  • Nozzle Spray

    Is the nozzle actually spraying to the left or are you seeing the fire veering to the left? If it is the fire you are watching it may just be the electrodes still a bit misaligned. The fire will follow the spark if it is misaligned. Also, does this have an R8184 or R7184 on the burner? If it is misaligned electrodes and you are dropping out the spark, the flame generally straightens out again. With constant ignition it will continue to follow the spark. Hope this helps.

    And if that doesn't help

    the firing head may be distorted. Replacing the head would cure this.

    nozzle adapter

    One thing to look for an out of square cut on the nozzle adapter. I think that Firedragons' website has a tool to resurface the nozzle adapter and ensure it is square. I have only had this problem once and I just replaced the nozzle chassis and it fixed the problem.

    Check for a dirty, bent or misaligned blower wheel. Also does it have the correct motor? Some burners require a closed end type motor.
