Is there anyway i can get more air flow out of my stove,it just seems like it dosent move enough air.The manual states the hotter the stove gets the faster the blower goes ,and that dosent seem to be the case.I have replaced the circut board and enhancement board thought that might have been it but no luck,i like the stove has worked good but if the blower would move more air it would be great,any ideas?

When was the last time you removed the blower and cleaned the impeller? This should be done at least once a season and if you have pets more often. Maaybe a couple times a season at least. Dust bunnies stick to the impellet and reduce air flow.

I have done a thorough cleaning including blowers,exaust,removed all ash cleaned burnpot ect.ect. this stove has always worked ok but i had always expected more if the blower output was higher it would blow me out of my 1500 sq foot ranch , the heat that comes out of stove is nice and hot but doesnt come out with much power.if i can find a blower with more cfm that will fit do you think it would push more or would the board limit it?

Member Don2222 has some experiance with the pel pro stoves. I don't, But if you have a volt meter you can carefully check the supplied voltage to the blower to see how much its getting. or you could carefully rig a lamp cord to bypass the control and power the fan directly to see if it has more flow/volume.
If you are not used to playing with electricity I do not recommend it. Always unplug the unit before playing with the stove!

Please tell us what the controller is on that Danson stove?
You can safely (as far as the control board goes that is) replace it with any blower that can move more CFM and fits on the stove that has a current draw of no more than what the current blower does.
There are a few other considerations that include making sure to not move the air so fast that it doesn't remove enough heat from the heat exchanger (this results in a couple of different possible outcomes that you do not want to have, one being a high limit trip and the other being sending a lot of the heat up the flue).
the blower on it is a Dayton 134 cfm thats the blower size thats supposed to be on it
like i said the heat that comes out of the stove is hot almost scaulding if your hand is 4" away just more output would be awsome!

Is this the current blower you have http://www.drillspot.com/products/47646/Dayton_2C647_Shaded_Pole_Blower
I don't care about the current temperature it is 4" from the stove, if you get a stronger blower in there it changes what comes out at the stove and into the room along with what goes out the flue. What I'm concerned with is what it is going to do to the temperatures in the flue that that Harman ESP is going to see in this case or what the thermal protection on the exhaust blower is going to see.
First we have to match up the electrical requirements, the attachment configuration and size, then find a blower that produces more output in the same physical size range without causing the controller to go poof.

Yes that is the on, i understand that a different blower needs to be the same or less amperage ,I was looking at the grainger website for blowers(they have a large selection)and if i could find one with better cfm i would buy and try it

I'll see what I can find sometime today, I plan on using Google to gather information on what is available for 160 CFM to 200 CFM blowers as a starting point. I have a 230 CFM one here and checked its plate and it pulls to much current.
At one time Harman was using a two speed in some of its stoves and had a rocker switch to change the CFM.

Maybe the motor on the blower is old and tired.
I have read threads on here, where people have replaced their blowers with new ones that have the same CFM and notice a huge difference.
Not sure who the members were but if you search you will find it.

You can include me in that category. I replaced the blower on my Harman Invincible with the Dayton one from Grainger referenced above and it made a world of difference for me.
if i cant find one with a little more cfm that will fit ,i will probably end up buying another dayton

One thing to look at is RPM of the blower. Your present blower is only 1500 RPM's. You can increase he CFM's by increasing the RPM's. Look at the current blower and see if the lable lists the motor numbers. Then look at grainger to find the motor and compare its spec's(shaft size and length) to find a motor with higher RPM's that will easily bolt in.
I'd also add a rheastat inliner so you can tweak the speed of the higher RPM motor.

jtakeman,
I've been looking and the published data for all of the blowers I've come up with exceed the current blower's current draw.
If the controller could take anything under 2 amps it becomes a case of what one physically fits.

the closest i can find is 1TDP9 looks like it will fit in the space but i will have to fab the mounting flange,would it matter if its a psc blower or shaded pole blower?

Yes it matters. A shaded pole motor is what you want. PSC(split phase capaciter) Do Not like to be controlled with a voltage/speed controller to vary speed.

Pat M,
I'd talk to grainger about being able to use that permanent split capacitor motor in place of what you currently have and be sure to let them know that it is going to be used with a triac based speed control system.
A number of shaded pole motors are being replaced with PSC units on both new and older stoves..
But in general what jtakeman is saying is correct.
