Fan Blade, Exhaust Blower, DC

Part #MF3642

(for all DC Magnum units)

• Unplug the stove before servicing unit.

• Open side panel.

• If you have a model of Baby that has the inspection cover/plate on the outside of the

exhaust manifold, you will be able to take off the cover/plate, to change the blade.

• Take the old fan blade out use a ¼” Allan wrench, loosen the set screw in the center of

fan blade. To loosen set screw, turn counterclockwise.

• Lift old fan blade out, screw set screw clockwise to tighten.

• Install new fan blade, use a 1/8” Allan wrench, loosen the set screw in the center of fan

blade. Slide fan blade down shaft. Make sure that the blade is about 1/16" away from

the back of the housing so that it will not scrape when running. This is not an exact

measurement, just make sure that if you push the blade toward the back of the housing

and turn it by hand that it does not rub on anything.

• Tighten set screw, turn clockwise. Add a light coat of red (RTV) silicone to the gasket

on the cover/plate and bolt it back on.

If blade installation requires blower to be un-installed try to leave the exhaust pipe (this is the

short piece of metal pipe that bolts to the exhaust blower and then goes out the back of the unit)

on the draft blower. You should be able to take the draft blower off once you disconnect the

venting from the short exhaust pipe on the draft blower. Be careful not to harm the gasket that

is between the draft blower housing and the steel housing when taking off the draft blower. If

you do break the gasket or if it looks like it won't seal, I would suggest ordering a new one.

You can take silicone and seal the gasket when you put the draft blower back on but it will be

really hard to get off later so I do not recommend it.

• For the MagnuM Countryside, the tools needed are a 5/16 inch or a 7/16”, tube of high

temp red silicone and caulking gun, ¼ inch socket, utility knife for cutting out old

caulking, and a scraping tool for removing old caulking and housing gasket.

• Unplug the stove.

• Open the left side panel. (It will be necessary to unscrew the knob from the manual draft

control).
