In-line fan as a Power Vent?

In-line fan as a Power Vent?

PostBy: jkabdoors On: Wed Apr 25, 2012 4:50 pm

Can you use an inline fan that you would use to move the warm air or move the cold air as a power-vent to help keep the draft in your chimney on a stoker?

No. The power venters for coal stoves are SS and even if that didn't make a difference they don't have wires, motors and other parts inside a pipe that is going melt them. If you hooked one inside a vent pipe I'd give it a few hours before it was toast.

A power venter would be a device that would allow complete exhausting of flue gasses. These can be at the boiler, midpoint or end of the draft system.

A draft inducer is a device that assists the natual draft of a chimney. These are typically placed in the breeching from the boiler to the chimney. They provide a boost to the flue gases.

Both devices are engineered for their application. Special materials are used to withstand the higher temperatures and corrosive nature of flue gases. Most incorporate some sort of control to help interlock the fan with the boiler.
Selection of the device in respect to the nature of the flue gasses and the size of the boiler is very important for proper and safe operation.

A standard inline fan would not be equipped to handle the temperature and corrosive nature of flue gasses. You just cannot take any fan and stick it inline and say it will work or work safely.

Spend the extra dollars for a unit designed for your application. The manufacturer will have application and sizing date to assist you to properly select the unit.

Have a look at these, I use the AD-1

- EDIT -
I see they have the DJ-3 which is smaller and would probably be better than the AD-1 since many of us had to modify the speed control on the AD-1 to slow it down because it made way too much draft on the lowest setting. Maybe someone with a DJ-3 could confirm?

If your chimney is marginal in this weather you can also try blocking off part of the combustion blower inlet to adjust over fire pressure. You should have some type of draft gauge but you can try blocking half with duct tape if that works you can do a more permanent and adjustable metal plate later. I would make sure all pipes are clean and no holes as well. If you need to you can give us a call 570-752-1811. I am assuming you are talking about the Pocono in your avatar? Dave

Thanks everyone, my Pocono has a powervent system. My buddy that has the Harman Mag Stoker does not have a power-vent it is just hookd to his chimney. He was just wondering if would be possible. Would he have to bypass the chimney to install a power-vent and make a new hole?

If you have a chimney why would you want to powervent? :?

In the warmer weather he is smelling that rotton egg smell, only a small amount. He was just asking what could be done to take the exhaust out.

Need a manometer, and on the mag there is a restrictor plate on the combustion blower to close so you can lower the pressure in the fire box. That would be the first step.

Looks like the DJ-3 might be an improvement over the AD-1.

that ad-1 looks great! Im not sure why this happens, he never had this problem when he burned wood. He and i are both new to coal this year i had mine installed by a dealer and have no problems he bought his used and i think it is not installed the rite way.This will be a summer project as far as his chimney it was just cleaned pryor to the Mag install.

There is two differences, firstly the combustion air creates some pressure inside the stove. Secondly the coal stove are much more efficient, less heat in chimney means less potential for a draft.
