This was the second season that I’ve cleaned this particular stove. I was amazed just how much ash accumulated during the burn season. When I put the Dwyer gauge to the stove and got such a low reading I figured the exhaust blower or the control board were shot but once I started the cleaning I realized it was simply very dirty. The Dwyer gauge, a.k.a. magnahelic gauge, measures air pressure, negative or positive and gives you a visible and concrete measurement of the results of the cleaning. It is used to “dial in” a stove to the manufactures specifications upon completion of the initial installation.
Here the hose from the gauge runs to a hole conveniently provided by the manufacturer for just this purpose.
Yes, that reading is with the stove on and turned to its highest setting. The next set of pictures will take us behind the insulation panels and the removable ash trap plates.
So now that we have the insulation panels and the plates removed I am going to show you the convection tubes and the shelves left and right of the tubes. I use a bent bottle type brush and compressed air to clean the shelves.
And, now that the front of the stove is done its time to pull the exhaust fan. Clean the fan, clean the chamber leading to the fan, clean the pelletvent, clean the convection fan on the other side of the stove and oil the motors.
The two pictures above were taken by my youngest son (11 yrs.) it was “take your child to work day” or so he told me. When the stove was all put back together we hooked up the gauge to see if we had done any good.
The results: from point nothing (.01) to .32, and the stove looks good too.
