glad to see you're still with us!! :D

too much combustion air is a bad thing, even though you aren't smelling anything now, keep an eye on the hopper lid. if you see moisture on the underside it would indicate exhaust heading that way and you may see that before you smell anything.

Don,

The Vari Speed control wont hurt the C Framed electric motors??? Meaning cutting the voltage down on them??? I'm no electrician.. : - )

I have one on my Disto Fan, but may just fabricate a slide to block air going into the combustion area via squirrel cage fan..

Leadslingingdaddy,

The older Alaskas, Readings, Leisure Lines and anything else with the old Tri-Burner stoker mech runs on the very same motor. The only control these stoves have is a reostat to control the motor speed and a threaded nut to set the feed rate. No thermostat, no noth'in! very simple.

This old Alaska is heating my garage. The gearbox and motor started squeeling like a banshee about 2 monthes ago. I still had the 140 in the garage all apart, so I pulled one of the motors off of one of the 140 mechs and put it on the old Alaska, same part number and everything, runs on a reostat for motor speed control.

The reostat is in the little control box to the left of the stove.

So, Yes, these motors can be run on a speed control.
I have only had the 140 for a few months now and I have never read the manual, so the way it is hooked up is just the way that I thought it would work best. I never even considered that the Varispeed would conrtol the distrobution blower. I don't know why you would want to do that?

Don,

My first Alaska stoker stove had a 265 cfm distribution blower running wide open . Our basement was always at least 15 degrees warmer than the rest of the house. Alaska offered an optional 500 cfm distribution blower for this stove also.

My 140 has a 1650 cfm distribution blower with a variable speed and it's an option I really love.

I have it set to run when the plenum temp gets around 150 degrees and shut off when it cools down to about 90..

Without the speed control it would cool down really quick and kick on and off constantly.

I found my sweet spot at about half throttle and I no longer blow the wife's table lamps over in the living room. :lol: And my basement is only a degree or two warmer than the rest of the house.

I'm thinking it depends on your duct arrangement and the size of your distribution fan weather the variable speed control fits your needs.

I have the same high output distro fan with the vari-speed control. May buy a couple more from the way it sounds to slow down the combustion fans if I ever run both sides of the stove to keep the internal pressure down.

I am getting a tstat this week to do what you are doing for the stack temp. High low shut off.

Paul,

My 140 also has the 1650 cfm blower. My 140 seems to somehow restrict the flow of that big blower. The spot that I have the 140 is where my Harman SF3500 used to be. I put it there because there is a plenum into the main trunk there. The Harman has a smaller cfm blower, I think 1300 or 1400, but when that one kicked on it blow the curtins around upstairs, the 140 just bearly moves the curtins. I like my 140 setup a little better, the bedrooms in the back of the house stay a few degrees cooler the with the Harman.
I don't understand why this 1650 cfm blower moves less air, but it does and it is working out OK for me.
My fan switch is on the back of the plenum near the middle. My blower runs very long cycle times, no short cycling.
This pic is before I completed the tie in to the plenum. The fan switch goes in the hole just above where it is sitting in the pic.

Leadslingingdaddy,

You can buy those Alaska reostat boxes from Jono Ace Hardware on ebay. I think they are $65, you unplug the combustion blower, plug the blower into the reostat, then plug the reostat in where the combution blower was plugged. Bang! adjustable combustion.

My fan switch is set very low, I don't think it sees a lot of heat there, 120 on 100 off. if I set it much higher it doesn't come on at all.

You better get that thing crank'in, It's gona be COLD tonight!
