My draft inducer seized up last week. So, today was spent cleaning the stove and installing a new draft inducer and replacing a section of pipe. While the stove was down I decided to install the anti- explosion louvers from DS Machines.

what are the louver,a hot air passage thru the fire?

Yeah, I guess they are supposed to let combustion air across the top of the bed of coal to keep the explosions down. They work like over fire vents I'm guessing. They seem to be working because on a new fire I usually get a lot explosions but I haven't had any but one tiny one since relighting this afternoon.

How are they held in place? Do they latch in between the fire brick and the piece of angle that holds them in place?

Does anyone know if these are now standard equipment of DS Machine stoves?

They replace a brick. There are little tabs on the louver that hook onto the channel. I probably should've taken a closer picture of them installed.

Lsayre, I believe they are standard in the #4 and they came in Coalfire's 1500 that he just procured. They should've been putting them in all of their stoves from the get go though, they seem to be working.

Not standard on any of the models. You only need them if you have a problem with explosions, Every situation is differant.

I might look into this for next year.... Mine usually will puff back if the whole coal bed is covered after a shake-down, but it's not terribly violent, at least not enough that I'm concerned about damaging the stove or the pipe.

IOF - do you happen to have any of your puffbacks on video?

IOF nice project,

Is that copper colored sealant on your flue pipe the "Ultra Copper" by Permatex and have you found it works good in higher heat areas ?

Last year I used some black rtv on my ash door and it didn't last very long at all. This year I have a bead of the Ultra Copper around it hoping the 700* rating is correct and that it will last much longer.

The louvers seem to be like the Warm Morning's hollow corner blocks.Does D.S.M. only require 2 per stove

Thanks for sharing IOF. Are they cast iron made? Since you installed them, is there some over the fire gases burning difference?
Nice photos

They put those in all of the DS Energymax stoves.
I might check on them for mine,maybe that would help with burning bit coal.

Echo, yes it's the Permatex Ultra copper. I used it on all my door gaskets and they are holding up well, stove was around 700• a few weeks ago when I left the ash door open.

Posse, no, I never thought to record any of them. Some were so violent that they shook the house.

Nortcan, yes, they are cast iron.

Coalfire, thanks for picking them up for me.

Those Anti-Explosion Louvers are not a new design.

They were standard item on Riteway Stoves from back in the 1970's and 80's.

Riteway Stoves were a favorite of the Amish Community right up until Riteway went out of business.
It stands to reason why there are a lot of similarities in DS Machine and Hitzer's stove line-ups from the Good ole Riteways.

I have a pair of Louvers from a 80's model #37 Riteway. As was mentioned...same dimensions as a brick...to take ones place in the stove and channel air from below up to top of fire.
There were some smart fellows in the 1970's that figured these out.

SO its gonna give your primary combustion air a path to bypass the coal bed? Hows that gonna pan out later in the burn when ash starts to block air going up thru the grates? Seems it would be much better to have independent control of primary and secondary air.. Am I missing something?
