As Wood N coal said. I Literally make 2 adjustments a year.
Thats the truth. One for spring/summer and one for fall /winter. I increase my wilbert timer setting for spring/summer to prevent outfire.
I haven't adjusted it since Oct 9th and won't adjust it again until probably April maybe May depending. and off we go for another 6 months...
"""I'm sorry.....even if you are only burning in the winter, I find it hard to believe you make No adjustments.
Give me a break !""""
I won't take any offense to the coments! I'm a good guy! Honest.
