I have a new hearthstone soapstone 8031 model. I have broken it in with a few small fires. Now that I’m ready to burn hot I’m having a hard time getting it up to 400 degrees. My wood is seasoned. Burning good oak. I have a laser thermometer and when I point it on the sides of the stove It’s registering 370 degrees. The top of the stove is considerably lower by 79 to 80 degrees. Also when I point at my flu which is coming out the back of stove it’s only showing around 220- 230 degrees. The catalyst gauge sais it hot enough to close damper so I’m thinking it’s burning efficiently. I’m confused. I don’t want want a bad creosote build up in my flu. Maybe my thermometer is not accurate! I also have a soapstone thermometer on the top of stove and I’m only in the low burn range. Help!!
