This is determined by the BTU output of your furnace. There is a tag of the furnace normally by the burner assembly that will tell you the BTU. Here is a list of nozzle sizes for BTU. You can get more information on oil furnaces from my book, Forced Hot Air Furnace Troubleshooting and Repair at Amazon: BTU Nozzle size (gallon per hour) 50,000 0.35 55,000 .040 60,000 .045 65,000 .050 70,000 .050 75,000 .055 80,000 .060 85,000 .060 90,000 .065 95,000 .070 100,000 .070 110,000 .080 115,000 .085 120,000 .085 125,000 .090 130,000 .090 135,000 1.0 140,000 1.0 You also need to consider the angle of the cone at the end of the burner assembly.This is the angle of spray for the nozzle. The nozzle will have a marking on it such as 1.0/80 which means 1.0 GPH with an angle of 80 degrees. Be sure to match the nozzle spray angle to your furnace.
SR nozzle means "Self Reinforced Nozzle".

Convergent nozzle indicates nozzles will converge with an end closing together at the end divergent nozzles increase size at the end. If air flows in this direction: ---> Convergent nozzle > Divergent nozzle <
The Wedco Nozzle is a CARB compliant spill-proof gas can nozzle. With the nozzle in place you can invert your gas can and it will not leak. Then simply push the nozzle lock and push the nozzle against the rim of the filling throat of the tank you're filling to start the flow of fuel. If you lift the nozzle away from the rim the flow stops.
You get the rocket nozzle after you open the rocket nozzle box in the level with the blooper boss.
BTU x 1,055.056 = joules
BTU
About 2 inches
The answer: 17070 BTU The math: 3414 BTU = 1 KVA (KW) so 5 KVA = 17070 BTU
Jump on a red box with a weird symbol on on it and take nozzle that comes out. You have obtained the rocket nozzle.
70000 BTU/hr = 20.5kW > 70000 BTU/min = 1230.9kW > 70000 BTU/sec = 73854.2kW
