Nozzle replacement Econoburn 150

Those nozzles are really hard. They say use a hammer. I used an air chisel which seemed much easier without hammering the hell out of the rest of the refractory. The nozzle just sits on the lower poured refractory.

Joe, just brought my notes in from my boiler shed from when i did this in 2015 on my 100.( I got 6 years service from the original nozzle) So I will assume you read the instruction sheet supplied with the new nozzle kit. In addition to those instructions here are my notes: As Goosegunner said above, the old nozzle was easier to bust out with an air chisel (used a pointed and flat chisel) Be surgical here so you take out only what is necessary. Don't overdo it. (see the photos in the instruction sheet) My new nozzle was not a drop in replacement , i had to trim it to fit and did this with a masonry blade on an old circular saw and 4 " angle grinder with a masonry blade. Make sure you don't add too much water to the refractory cement, just a bit of water at a time to get a thick consistency like the instructions say. I used a margin trowel to spread the cement and feather it around the nozzle on the floor of the burn chamber. If you haven't done it already , do a search on the forum and you will see some other threads on this as I recall from a few years back-seems like everybody was doing it , once somebody mentioned it on the forum.

I used the air chisel as well took minutes to remove the old nozzle.I probably changed mine a couple of years too soon.
I live a long ways from New York so i am going to try to make my own replacement. I bought a bag of cast able refractory cement and stainless steel needles.I believe it was 2700 F rated it was the highest they had.
I also have a nozzle that is to small for my 200,could you measure yours to see if it is the same as the small one i have?Thanks i would like to know what it fits so i can pass it on to somebody that can use it.
Mailing cement around gets expensive.
