ash removal , barometeric damper screw removal

I have a 520 built when or near when I was born 53, I have a question about ash flow, the flat sheet metal was oxy aceytlened burnt out but i reinstalled it. I have noticed that newer models have different flat metal configuration with slots of the flat metal under the pot, from that eras ash removal . Is anyone able to educate me about this. Also on the barometric damper I am installing there is a screw installed on it that states remove for coal fueled units , the question why?.......................... there is so much i dont know.

All the sheet metal does is to direct the ash to the can and keep it from falling into the bottom of the base outside the can. Screw two pieces of angle iron to the side and slide in a piece of sheet metal with a hole in it and forget about it.

I have no idea what they are talking about by removing a screw in the damper.

On the baro, its probably to reduce weight on the flapper, since coal can have a lower exhaust then a oil or gas fired appliance. So it responds quicker.

A picture would be good. The damper supplied with the stoker is the exact same damper as supplied with oil units.

I have seen this tag/label also, it is found on all the Field Type M barometric Dampers.
No label show at wesite...but bolt can be seen middle right of center...http://www.fieldcontrols.com/m_mg1.php

It is simply a 10-32x1/4" machine screw w/ square nut attached to inside of the damper swing plate. Removing it will obviously leave a 3/16" hole and reduce the weight by that much from the swing plate.

What effect the removal has I can't say???

The only thing that matters is if you can get a neg. .04 vacuum in the stack when it's firing hot.

I have the same damper hooked up to my Keystoker 90. I have the screw in, and also checked the manual on their website and there is no mention of removing the screw :?

Just like the OP, I have 2 of them here still in the box (NOS) that have the stickers w/ red arrow pointing to that screw and saying "remove bolt if plant is coal fired".

Seen this in the manual...

IMPORTANT: Don't change positions of weights on rear of gate. Except on 6" size, remove bolt and nut in upper part of gate if furnace or boiler is coal fired. Leave bolt alone if heating with oil. Bolt is identified by small decal with red arrow. On 6" size, follow directions on green card.
