Wood gun Operation questions

[muncybob]

I think my manual stated to expect to replace the center/nozzle brick every 15 cords which seems a bit optimistic. Due to a small fire in my horizontal pipe run a few years ago I'm a bit paranoid andI replace e/o year which is more like 8 to 9 cords.

I heat 3 different buildings. Shop, finish room, garage and home so have some pretty serious square ftage to deal with.
Would appreciate some user's to connect with. Mike from AHS gave me 3 connections here in MN. but more is better.
I'm concerned with the fire brick life?

PM me and I'll be happy to give you my number, so we can chat.

Theirs a bunch of guys with WoodGuns, all of which are on this forum. They have owned their units just as long as me and few guys own it a couple years longer.
I'm the only one who has had to replace the refractories, Ive either seen them in person or by picture and their refractories look brand new.
Maybe I had a bad mix of cement.

Im talking about the main refractories, the center bricks need to be replaced like Bob said, every couple, few years, depends on how many cord you push through it
