I took on the challenge of cleaning out the remaining ash from Hitzer 503 insert yesterday and got her set for summer. Seemed to go easier this year with ash removal, inspection of bricks and metal parts, and cleaning of chimney, which produced slightly less than a 1 gallon volume of extremely fine fly ash. Good to get things cleaned up after October to April burn. Did notice metal deterioration on back of hopper assembly and will either replace that or weld a replacement plate onto the assembly. Sprayed all metal parts with Cortec (http://www.cortecvci.com/Products/single.php?code=10051
), which again worked out well. Easy to apply and can sprays upside down and at any angle. Last thing for the summer is to put some DampRid in there.
