Apology to Squeal Appeal and Thanks for Your Payment at Last
Good to hear that you received my controller and burner.
Thanks for your payment again in Paypal.
and Apology for my other post that I say cheat and lie.
1.Regarding the burner
The cover is designed as water tight, you can simply pour water around the cover.
Add lining by fire cement or even mud around walls beneath the grate.
Also add short lining( 1 " high) around walls just on top of the burning element, the cubic metal structure.
Different size of fuels need different grate. You better use broken charcoal by present grate, which is cheaper than wood pellet. If you must use pellet, the grate is OK too. Even some pellet falls down the grate, just leave it, it will continue to burn as the burner is reverse flow
2.Regarding the controller, please explain in detail. Basically it shall be good.
