The difference between an A or B nozzle can be very small
our cause a hell of problem. Testing equiptment helps determine proper adjustment of the furnace.
Also it may not ignite or cause delayed ignition
Be cautious

    NOZZLE QUESTION

    Hello all and happy holidays! I have a quick question about my Hot air heating unit.. I have a becket head and i'm firing a .75 70deg nozzle-which is what i should be using.. The unit says--to use a B solid -I only have a Hollow in that size right now.. My question is--will i have any BTU loss and or heat loss by using a hollow Vs solid fire? Could i cause damage to the combust chamber? Thanks for all your help!! Happy Holidays!!

    nozzle

    The test equipment is the key. the look of the flame was ok when fuel cost was under $1.00 but those days are long gone.

    The pressure is important also. 100 minimum
    Merry Christmas and good luck with nozzle

    Nozzles

    Look at it like a cars tires. There are variations of fifteen inch tires and each vehcicle specifies what it should have. You can use what isn't specified but how good will it perform. A mfg specs a certain nozzle for a reason also.

    .

    you can just wait and buy the correct nozzle --but you still run the risk of having a bad nozzle ---if you don't have combustion equipment -its a crap-shoot --i think the delevan nozzles have the closest tolerances and closest comparison when you have identical nozzles -rating and spray pattern --but they can be different and i have run into a few defective ones ,by few i'm talking 3 in 18 years that i know for sure , it can happen

    Everything I read on oil said that the oil pattern should match the air pattern as close as possible. All flame retention burners have a more solid(right down the center) air pattern. The problem is that the spray patterns of nozzles can't be guaranteed. Any nozzle, new or old could have a bad spray pattern. I have found doing CO testing on oil burners could totally decipher the difference. This is irregardless of the smoke. CO can also can determine if the angle is good or bad along with other mechanical settings.
