Hi guys this is my first post and hoping someone can help. I am about to hook up the 50-93 I just purchased but noticed that the back damper door that is controlled by the thermostat knob does not move until it hits the number 4 setting. I tried adjusting the chain but then the door stops opening about 12. How can I adjust this properly? Also does that door open and close as the stove operates or does it stay at the same position? Thanks for the help. Super excited to get this going!

C, hook it on the 28th ball from the loose end. That's a good starting point & get back to us once you get her fired up good. I use self light briquettes, full bag. Fill slowly through front door to bottom of hopper & then fill hopper FULL.

You won't know for sure what is right until the stove is hot. Like FF said, try the 28th ball, assuming your stove is identical to his. Another way -- though mine is not a Hitzer -- is that on mine the damper is open about 1/8 inch when the stove is stone cold and the dial is at its lowest setting.

Standard 50-93 setting is 28 balls cold.

Not on mine. I've used 18 balls in from the loose end since it was new. Maybe the older models had a longer chain? The current models are shipping with a clip on the end of both chains so no more guessing.

Thanks guys I will see if is on the 28th ball. Problem is that if I go one ball up from where I am now its to tight and the door is open on zero. If I go down one ball it has to much slack and begins to open at a higher number like 6 or 7. Does this door move without touching the dial while the stove is running?

I have a Vigilant 2310 with a similar air control. The door opens as the stove cools and closes if gets too hot...without human interference. ;)
The spring moves just like the magnetic thermometers folks stick on stoves and pipes.

J, you will not see the door activity unless you sit & watch it for a couple hrs. Myself & a few other 50-93 users have tried the 28 ball & found it to work well. Don't get hung up on numbers--set it where-ever you think it works best for your stove.

Yes. That's its purpose. When the stove cools, the door opens more to let in more air, making the fire hotter. When the stove heats up, the door closes more to reduce the fire. In theory, a given dial setting will maintain a steady stove (stove -- not room) temperature. The door movement is usually very small, like watching the minute hand of your clock move.

Here's a Wikipedia description of the bimetal thermostat.

With a cold 50-93, if I'm not mistaken, the flapper door is open when dial is on low (factory setting). What you're shooting for is dial to be straight up, and flapper door closed at average room comfort. Then you can turn the dial a little either way. Example: turn it down if outside temps warm, and up if outside temps drop.

Quick question about this topic, my chain somehow came off and my stove is up and running, how do you judge where to set the chain at? I tried turning the knob to zero and using the 28th ball but that holds the door all the way up to the point I can’t even hook it, any thoughts?

28 from the hanging end? If you're idled down pretty low, I'd just hook it where ya got maybe just a sliver open on the flap & really keep an eye on it. PLUS--take pliers & gently squeeze the clasp a tad tighter--don't bull it!!

Question: How long is the TOTAL length of your chain? Maybe it's been broken. Maybe someone had it set, and cut off the excess. If that were the case, you'd put it on the very end. Measure over all length from end of chain, to the other end, and let us know.

If it's still factory length, do as Fred said; 28 beads hanging. At this setting, the flapper door will be open on a cold stove. What you're shooting for is; with stove up to temp, dial pointing strait up, and flapper door closed, or just about closed. Actually, the outside temps are still mild. So you may want to have the dial on about 7, or even 6 . When old man winter sets in, you'll have it turned to 8, or 9. Once you get it set right, you'll never have to touch it again.

Don't get stuck on the numbers. They are only for reference. I'm letting you know where I'd run my 50-93, with fan on low. As a rule, Fred doesn't use his fan. With everything the same, he may run his 50-93 on 10 at the back dial. And if HITZER has shortened the over all length of the factory chain, then you'd have less than 28 beads hanging. We are giving you starting points.

Did you buy the stove new? If so, you should have left it at factory setting. You can also call HITZER. Ask them how many beads hanging.

If bought used, I'd follow Fred's advise of 28 beads hanging. I'd start with over all length of chain. I say this ONLY because previous owner could have cut off excess.
