Quad E2 new mother board low heat???

Is the airflow the same, or higher? Higher airflow would reduce the temperature, but the heat would be the same.

Try a search in the box upper right for some reading on the Mount Vernon E2 ... boards were switched out to prevent explosion!

I'm with BrotherBart, ask for money back or a stove that delivers the BTUs as advertised.

52,460 BTU is the advertised - wonder what the output is now with the new board?

I would suspect that the programming on the new boards changed the air/fuel ratios as we have seen comments on auger jamming/not dropping pellets and then dropping a larger fuel load prior to the board change. They likely have increase combustion air meaning more heat lost to the exhaust or slowed auger feed resulting in less pellets so less BTUs. No official statements or reports from independent agencies so left to surmise...

If 5 is now what 3 used to be heat-wise, would the stress levels be higher?

Ok everybody, lets take a stab at this. We have started changing out the E2 Motherboards including the one in the store. We have a MV AE sitting right next to the E2, their flames are very similar now and heat output seems the same. Quadrafire has said the new boards will not significantly change the heat output, supposedly around 10 percent. If that is indeed the case, shouldn't affect many people. Fuel quality is still the biggest variable in the equation. Have had real good results with LaCretes, SprucePointe and Lignetics this year myself, although I do run Enviros at home. The E2 flame characteristics looks to be more in line with the AE, a little less fuller flame with the new board. Heat output is still awesome, at least at the store. Haven't had much feedback on the ones we've changed, and with milder weather, I'd expect we probably won't have much for a while. Hope this keeps the Quad faith.

Sorry LGT, didn't see your observation and question. The updated board has an air to fuel being fed rate change. More air being mixed in with less fuel, for yes a bit less BTU output perhaps, but its feeding a little less fuel too, so you're not losing the BTUs, its just eating a little slower. This supposedly will result in a little cleaner burn, and give overall better operability to the units. No answer yet to the inquiring of is Quad going to reduce the input BTU/hr rating.. I hope this doesn't shake anyone's confidence in this stove, it is a fine heater. edit: This stove is a fine heater, but I can't discount the fact that these explosions should not be happening- hopefully this upgrade will cure it from happening, but I sure can understand the doubts, hopefully no one else gets hurt.

Considering the stove didn't work right with the original board, you could make the argument that now the stove works as advertised, because it isn't clogging itself shut or sending glass shards into your living room (so far).

LGT hows the e2 been treating you with the new board?

Clean her properly (Chimney, interior air flow pathways, all motors), lay her up for the summer months, maybe touch up the interior so no rust can live, maybe put in a box of arm and hammer for humidity control and she'll be ready to go this fall. (I'd unplug it too, in case any dirty electrical spikes come through..)

how often do you have to manually dump the burn pot on it? Also, do you have to shut the stove off to do this?

Really depends on how its running (heat level, pellet quality, how clean internally the stove is.) Generally speaking, not a bad idea to check it to be clear (the airholes in the burnpot) everyday. It has been found if you have missed ignitions, thats usually the cure, keep the burnpot clear. If you were running continuous on a manual mode setting, then probably every 2 days would be ok. Running on thermostat, the burnpot needs to be clean, or you will miss ignitions.

I am a new Quad E2 owner as of October and stove worked great in my opinion besides the intermittent thermostat issue... With the old board, I was getting 315-330 degrees surface temp from air exit. I've tried different air/fuel settings from -4 to +2 and am only reaching 240. Anyone else having these same issue with the new board. I want my old board back

Same pellet stock? Same runtime duration? Same blower speed? Same measuring equipment? Same house pressure? Did you average your first readings to rule out a false positive? I imagine there are some pre-sets from the old Tstat to the new tstat that have changed but doubt any of it would effect total output performance.
