looking for an inline booster fan for my pellet stove exhaust. ????

[excursion]

Hey all..
anyone know where I can get an inline exhaust booster fan for my pellet stove....I need to move my combustion air a little faster and I read stories where others have done this with great success.....
if anyone has done this please let me know ....it's my only shot at getting my stove to work properly...

What you're looking for is a draft inducer. I know that Kedel sometimes uses them. Someone with more experience with them than me would have to give you recommendations on them.

What stove? There are several stove makers who provide higher flow rate blowers for their stoves best to check that first than rigging an afterthought into the exhaust system.

It's a jamestown j1000 insert...
I put a new combustion blower in it...the rotation of the new motor is opposite the old one...jamestown said it should work fine.....it doesnt....

You want the new combustion blower to go exactly the same as the original.

If it was blowing out the exhaust you sure as hell don't want it blowing out the air intake.

Impeller direction shouldnt matter assuming the impeller blades are not directional.

Now how about tellng us how you know the blower is the problem?

Jamestown has an excellent section in their manuals detailing various burn issues and their solutions.

You can start by letting us know how the insert is installed and in particular how it is vented.

Some motors are reversible. What you do is pull the bearing caps off, flip the rotor around and reassemble. The rotor is the fat rotating part of the motor connected to the shaft, it passes through a hole in the stator which contains the epoxy encapsulated coil and laminated steel plates. Post a pic of the motor and we may be able to help.

WHAT???????????

 

[daffonce]

On my harman xxv the impeller blades lie on a straight line from the cemter of the blade to the od. You spin it cw or ccw it pushes air centrifgually out of the impeller sucks from the middle. If his stove has this type of impeller cw or ccw doesnt mattter. If blades arent straight then direction matters.

Look folks the stove isn't a Harman and it needs the air to go out the exhaust. I would hope the Jamestown folks would know how their stove works but I need to know that the air is going in the right direction. If it is fine then we need to know if all paths for it are clean and that the vent setup conforms to what the manual says is correct.

Placing additional items in the exhaust or air intake path isn't the way to go, in fact it is a recipe for major problems. .

I also wasn't kidding when I said that Jamestown has a decent troubleshooting section in that thing everyone hates to read let alone follow.

I also have no knowledge of weather the stove ever worked correctly, that information isn't actually in the OP's post.

 

[daffonce]

Description of the path would be important. If it has too many bends that could be overpowering the blower. Doubtful it is blowing air backwards or smoke would be filling house if not oakd or exhaust is going out oak either way think op would know that. I used my harman as an example as i have played with it the most. Many rudamentry impellers like in pellet stoves motor direction isnt important so jamestown is probably correct.

 

[JDenyer236]

Just because the blades are straight doesn't mean that impeller direction doesn't matter. The location off the inlet and outlet in relation to the impeller is what determines proper direction of rotation. Also If you look at a pellet stove impeller they are directional. Think of each vane as a scoop. You have the backwall of the scoop ie the impeller body and the side wall ie the fin. If the motor is running backwards it will still vent just not very well. Jamestown may very well have shipped the correct motor but maybe it was assembled such that it rotates backwards or just mislabeled. The OP should just be able to flip the rotor around and get the motor to run in the correct direction.

 

[tjnamtiw]

JDenyer hit the nail on the head as well as Smokey. The shape of the impeller blades defines the direction as well as the shape of the housing. Your exit comes off tangent to the circumference and demands that the air be pushed along that path. If the fan is running the other way, the 'scoops' are not scooping and the back side of them is pushing the air past the exit instead of toward the exit!
Smokey's right too. You don't put extra things in the exhaust to cover up a problem. You FIX THE PROBLEM! If your fan is running backwards, try what JD said, if you can. If you can't get another fan. To do otherwise is not wise. If you still have problems, then we'll go from there.

Yeah those old Jamestowns had combustion motor rotation the reverse of the majority of blower applications. If your replacement motor is a c-frame motor you can reverse the rotation by swapping the end bells. 5-10 minutes max.
