Hi all.
I'm just starting my waste oil heater journey up here @ Crossfield Alberta, Canada. (just north of Calgary)
I've salvaged a used nat.gas h2o htr, and plan to follow the Roger Sander's program.
First question: Has anyone tried NOT filtering used auto oil before use? Seems to me that so long as there is no particulate material larger than the needle valve opening, there should be no trouble?
(he said knowing he has no experience!)
Second question: Short of buying R.S.'s needle valve, does anyone know of a common part with the proper level of control? Has anyone taken a file to the ball of a ball valve, to allow a more "tapered flow"?
Cheers, Gorram. (short for "Gorram Reavers" an obscure sci-fi reference)
