Relationship Btw Blower Limit Control & Dial Heat Regulator

We bought a Hitzer 82 furnace with blower in August. Works really well, but the blower limit control casing around the dial was egged and it was holding the dial in one spot. We had not really been using the blower until recently and when I tried to pull the button for auto blower it broke off. When I took the cover off the pull knob was discolored like the plastic was old. That was also when we discovered the housing was egged. I called Hitzer and they sent us a new one. I had it installed last week and left the settings on the factory settings which are 100/off, 125/on, 250/high limit off. I think I understand how it works but would appreciate a lesson. I was going to adjust the dial so the high limit was 200, but am unable to move any of the little pins. I also want to know the relationship between this limit control and the dial heat regulator on the back of the stove. I can't seem to find any useful information in the literature that came with the furnace. Any help would be appreciated since I am always preaching to my husband how great I think this forum is.

I'm at a loss w/ all that, but I do know there's a couple experienced 82 owners on here. Be patient my friend.

This is blower control and H/L.
High Limit setting on Fan/Limit Control is *fixed*, meaning not to be ever moved/adjusted.
It is the High Safety, and is to kill the *burner power* to the stove if/when setpoint is reached.
Not sure that Hitzer 82 has any *burner* to stop.

The other 2 pins , on and off setpoints do adjust, they are tight though and one must hold the round dial in one hand firmly while adjusting them.

The stove temp/fire rate control is the rear dial. It controls heat of fire from within stove only.

Thanks for that explanation. Now I hope there are some 82 owners who can guide me on that dial heat regulator.

I have an 82 a dad well. I have experimented with a number of different settings with the limit control and heat regulator. Some of how you have it set up will depend on how you are using the stove. That high limit is not wired to anything, so it is only the fan on and off that you need to worry about. I'll check to see where I have mine set. The main thing with setting the limit is, when you are running the stove at cooler temps, how often do you want the fan to cycle on and off? Or do you want it to stay on longer? Regarding the dial a heat control, what are you looking for precisely? I've had my 82 for three years, and it has been a learning curve, so I'd be glad to help if I can.

The only thing the literature says is not to move it more than 1 number per day because it will take that long for the furnace to adjust to outside temp. We are in southeastern Pa and the temps have been all over the place this winter. I guess my question is what number do you set yours on in relation to the outside temp? And then if its going to drop 10 degrees for a couple of days do you change it? If so, how much? Or how often do you change it? I have been leaving it on 8. It's supposed to get super cold so I turned it to 9 today. I don't get all into it like a lot of people on here with stack temps, and all that because I don't have the time or knowledge. I don't even know what region my coal originated from. I wanted the coal option because we're getting older and it's easier than doing firewood. My husband it a wood guy and still doesn't get the coal thing and is always in the furnace like he would be with wood. He's better than he used to be. The mantra here is "leave it alone"

New hitzer 82FA owner myself (since November) so no expert here.

The dial and fan controller are independent of each other. I left the fan controller at factory defaults. It cycles on/off just fine when needed.

On cold days (single digit and below) I turn the dial to 12+. Anything over a 9 and the fan never turns off. Up at 15 the furnance puts melt your face off heat out.

Biggest issue I have had I'd clinkers. Clinkers can greatly reduce the max heat out put. Now that I have figured that out the furnance is wonderfully.

Yes, twice a day tending is all you should need to do. We should be in the same climate since I only live about 10 miles from you. I run mine from numbers 5 to 8 depending on how cold it is. If you look where the chain hooks together below the dial, I have 14 balls past the connection. I have a coal stove upstairs running to, but even before I got it and the 82 was it, I don't think I've ever ran it over 9.5. Old farm house with no insulation.

CorrosionMan and Ashokin, what is the size of your cold air return into the blower box? My nephew who does furnace repair, installation , and duct work came and helped with heat output into the propane furnace duct and the cold air return. He doesn't have wood/coal experience but was somewhere doing repair work and there was a coal furnace also. He asked some questions and used 14" round for the cold air return. Well getting ready to go to Florida for a week so I doubt I will see any replies till I get back.

Wide open. Filters on both sides.

I was tied in to about an 8 x 20 cold air return before. This winter I disconnected it and put a filter on each side of the box and am using basement steps as return. I think it is actually working better that way. I know the fan is moving a heck of a lot more air. I also have run it with an elbow off the top pointing toward the basement stairs and the small panels removed from the bottom, more gravity style, and it heats about as well that way, too. It just takes longer to get the house up to temp and doesn't keep the temps quite as even from room to room.

Love your diamond plate hearth pad btw.
