I have a thermocouple mounted in the stovepipe right outside the VF, it very rarely goes over 400*F...if it does that usually means that either the HX needs cleaned, or computer is turned up, not on low anymore.
280-350 is a pretty normal operating for me, on low, which is where it stays 95-98% of the time for us...might move it up to medium for a "polar vortex" in January occasionally.

I have to concur with this I stuck one of those magnet gauges on just for fun a few days and I stayed mostly 175 to 205. So likely internal temp would be over the 250 threshold. However I have found that it burns so clean the temperature swings doesn't really hurt it none. These are very easy furnaces to run by far the safest imo. I have a very similar setup 2 45s about a 20" section of single wall, somewhat shorter 18' chimney 6" insulated stainless inside large brick through middle of house. Baro been on 4 the whole time and flaps fairly regularly.
Thanks for all the responses everyone. Sounds like my magnetic thermometer is right on track then. My only concern now is the ice build up on my famco wind cap. My chimney is a 25' tall cinderblock chimney on the exterior of the house, and i have a 6" liner running down it. I wonder if i should have insulated it... hmmmm
I have a question for the VF100 folks. I have the VF100, the buzzer goes off constantly. After playing with everything to stop the noise I found I can make the noise stop by placing a cloth over the thermocoupler/thermometor for a few seconds. It will start up again in about 20 mins. I know the wood could be dryer than it likes, but I cannot change that. How do I get it to stop beeping for hours on end.
You talking about the over temp alarm?
That doesn't sound right...better call Lamppa.
Is this a brand new unit?
If it's the overtemp alarm, I'd start with making sure your draft is in check and that you have no leaking door seals. If that checks out then I'd give Lamppa a call.
FYI, drier wood would only make the issue worse....not better.
Like asked above, is this a new unit or.....??

You must be loading it pretty full? That's about the only way I get the OT alarm...a big load of super dry wood, especially on a big pile of coals, that'll do it!
