We replaced the raincap on our outdoor flue with a Tee and 2 elbows (cowl) to combat downdraft but we had major downdrafts & smokeback this morning with our heater.
What have other folks who live in wind prone areas done to combat downdraft? What can we do to ameliorate this problem?
This heater is largley based on donkey's 6" dragon burner except our core is comprised of firebricks (rather than the dragon core) surrounded by perlclay insulation encased by 30g barrel surrounded by 55g barrel.
Thanks
