with draft that strong, you can get wild with flue path, and it will still pull it.

Base is 5.25" AFF

This puts the bottom of my grates and fire pot about 18" above the floor.

yeah, i went thru about a month of gymnastics at the start of the season last yr. trying to arrange a dependable way to get the draft over even a small and slow fire under -.10

my plans are for a conservative gas flow path, staying very close to the volume and cross sectional area ratios observed in the best of the later original base heaters.

i'm not trying to re-invent anything, just optimize an otherwise already pretty good stove.

Too much draft is easy to control in a number of ways.

But, I think the two best ways are with smaller coal size, or check dampers.
Many of the old stoves have adjustable check dampers - either built into the stove, or range top, or in cast section of pipe.

Check dampers allow a hot fire, but let in cool air with the hot gasses in the flue that can cause such a strong draft.

Here's three types of check dampers. You might be able to incorporate something like one of these in your re-design.

The first picture is the slide type near the pipe collar of a E24 Round Oak.
The second is the slide type in the top of my kitchen range.
The third is a rotary type in the pipe elbow that comes with a #6 Base Heater.

All three work well at helping to tame and slow down a strong draft.

Steve,

The underside of the back pipe base casting for my 118's is 9 inches from the floor. The floor of the ash drawer is about 8 inches to the floor.

that's great info Paul, the lower surface of my back pipe riser will be about 9-10 off the floor too.

Steve,

For what it's worth. As long as we're measuring to the undersides of stoves, I'll throw this in to give some idea of the other end of the spectrum of how hot and how far.

Like my #6 bh, my kitchen range has base heater flues under the oven. That flue path forms a flat, heated floor pan that is 18 x 18 inch and 14 inches from the floor. So far, those flues can get the oven up to 450 degrees. I've heard of much higher oven temps from a stove shop that uses a Glenwood range.

The point is, before the days of fire codes, rarely do you ever see a range on a hearth. At most, maybe some glass insulators under the range feet to prevent digging into the wood floors.

The hottest I've ever had the floor get under my range is in the mid 90 degrees - measured with an IR gun.

right, i agree. i'm not terribly concerned with air space under the stove.

i'm really only trying to replicate what was done by the period firms. i think they had that figured out too for best transfer of heat out from under the stoves and into the room.
