I fired my new Tundra II last week for the first time. Here are some observations.
- They include three bags of screws. A large bag of square drive screws, a small bag of self drilling screws, and a small bag of Phillips drive screws. The manual does not clearly detail the usage of the screws. After talking to them on the phone, I believe the self drilling screws are intended for capping off the unused plenum holes. I also believe the large bag is for assembling the plenum. I do not know what the small bag of Phillips drive is for. They are slightly smaller than the square drive screws.
- There is a display and two buttons on the electrical box. There is no documentation on its purpose except a note on page 33 of the manual. When I asked, I was told that it is only for factory use. When I said that pressing the left button, you could see the temperature of the probe. He confirmed this. Does anyone have more info on this, either from hacking, or otherwise?
- The connector on the electrical box for the plenum probe is not captive. You can lift it right out of the electrical box. The guy I spoke to didn’t offer any suggestions. I want to enlarge the hole so that the mounting ears on the connector will engage in the box wall, but I don’t want to screw up the warranty.
- The book only mentions the ash plug in the troubleshooting section. How hard would it be for them to add a paragraph in the operation section?
- I like the stove. The operation is simple. It has a convection draft. The combustion control is a two position shutter (damper) on the front combustion air intake. It is either open or closed. There is a switch on the control box to open or close the shutter. There is also an electrical connection on the control box for a thermostat. The shutter will be open when the thermostat is calling for heat, and closed otherwise. You can also switch the shutter open as an override to the thermostat.
The two speed blower comes on when the probe reads 125° and switches off when the probe reads 110°. I do not know what temperature activates high speed yet.
By filling the firebox and running the draft shutter closed, I can get a pretty consistent 12 hour burn - so far.
