Speaking of fan motors, I had a problem the other day.
My distribution blower started making sick noises. Then it made no noise at all..... I called the dealer & they started with a song and dance about not having some $#@@% yellow warranty paper on file (they were total robots about this
- !!!!) - so I wound up taking the blower motor apart thinking I could relubricate,restart and keep it going long enough to get it replaced.
What I found is something everyone should take a look at. My blower motor (not the blower housing, but the motor itself) was mounted up side down in the housing. When the motor heated up, oil that was in the bearings was able to leak out of the lubrication holes. Over time it ran dry & siezed up. I flipped the motor & soaked the felts with oil - spins like new now.
On my stove, the power cord was coming out towards the back of the stove. When I flipped the motor, the wire faces the stove body & the oiling holes face up. ( I never knew it had oil holes & no where is oiling the motor mentioned in the manual) Now that I know that I can oil it, its getting taken apart, cleaned & re-lubed once a season. I was amazed at how dirty the squirrel cage blades were. BTW-If it goes bad, no big deal, dealer wants $120, Grainger has one in stock for $65.
On the subject of efficiency, I recently covered both sides of the stove with 1" finned aluminum heat sink material ( 12"x15" bolted on under the covers) Closed off the cover bottoms by migging a 1" strip of steel onto them. Mounted some nice mil-spec rotron box fans to the lower face of the covers. More noise - More heat. I'll do a write up after I take some pics.
PS - Feed Rate Adjuster should be left at '3' - by running it at '1' you are just limiting the stove at full blast. In stove temp mode, the stove temp dial sets the feed rate (1-7) To put it another way - Feed Rate Adjuster determines how much ash you have in front of the fire @ "7" which is 100% output. Its factory set at '3' When I dialed mine in, '3' gave me a ~1.75" ash line - so I left it alone at '3' The 'stove temp' dial should really be labeled 'feed rate / room temp'
