Difficulty getting HARMAN MAGNUM STOKER COAL STOVE to run...

good pic, your plate is open further than mine. Is that fan all the way in the slot it is supposed to fit into?

That pic i posted below is what the fire is supposed to look like when on full burn. your combustion air must be going someplace other than through the grates. Does that controller have a variable speed control on the combustion fan? mine does not, it is either on or off. take the fan off and plug it in and see if it is pushing a lot of air out of the squirrel cage.

just throwing out some ideas.......

Titleist1 the pic was not posted. I open the baffle plate on the combustion fan and the flame has increased. I am going run the stove for awhile to see if the temperature increases and to see how the coal burns. Thanks for all the advice so far I appreciate it. The combustion fan has a high and low level.

Here is mine today. I think it looks farther back than it really is- coals turn grey about 2-2 1/2" from the edge. Is this good?

my bad, when i said "below" i meant the pic in the other post, i didn't post a second pic.

I did take a pic of the stoker in the basement, had to open the door because the glass in that one is etched more and you can't see the flame very well when the door is closed. I noticed opening the door knocked the flame down a good bit, but not nearly as low as your is.

ash is about 1" from the end of the grates.

mine is closer to the edge of the grates....only about an inch of gray.

I have my combustion blower on 24x7 on a fan speed control. Burns much better.

Harman Magnum Stoker Installation

Cover plate on the combustion blower does prevent blowback of coal gas through the hopper by reducing the air flow, but this also reduces the size of the flame and the heat output. I've had my Magnum Stoker for 20 plus years. In our older smaller house I had no problem with the draft with no cover over the combustion blower. Then we built a 2500 ft2 ranch and put the stove in the basement. I immediately had coal gas coming out of the hopper. I believe that newer homes are built so darn air tight that blowing air up the chimney puts the house under negative pressure preventing all of the air from going up the chimney. Some gets blown out the hopper. I installed a 2" PVC pipe to the outside and fastened it up against the combustion blower intake. I also removed the cover plate from the blower so it runs unobstructed and I have no problem with blow back. It also makes more sense to draw combustion air in from the outside rather than draw in room air that you paid to heat only to blow it up the chimney.

How did you make out? Give me an update. I bought a Super Mag as well and this post has been informative so far. You had service men coming?

The servicemen did not show, because I got the stove running very well. I bought a manometer and that corrected the drafting issue but I also had to open the flap on the blower to give it more air.

Glad to hear your stove is working better for you.. In interest of learning more about what was 'wrong' and what was done to fix the problem, could you share more about the 'fix' ??

What was your draft before you adjusted the baro? And after?
How far open was the flapper on the combustion blower? and where is it now?
Do you have a photo of the fire now with the adjustments done?

Thanks,,
