Jotul F45 Greenville Experiences

[firenightdance]

Waved goodbye to the F45 today. She was a great stove but it’s time to move on with my rebuilt Fireview. The Fireview should be a bit better fit with more radiant heat and lower output for those shoulder season days.

Damn! Who the hell will I ask for advice? . Thanks for the tips

This might not be the right thread to ask this, so please move if needed: I'm still learning my f45, which I started burning later in the 2025 winter. What is an ok stove (top) temp for it to consistently reach? I have a stovetop thermometer (have double-wall pipe going into ss liner/insulated masonry chimney; I am not planning on getting a probe thermometer), and the stove always wants to reach 600-650 stove top temp and stay there a bit before lingering (at the ideal?) 500+/- range. I have the front holes blocked with screws but that's it. Just want to make sure I'm not risking damage to the stove, but this is the temp it likes to reach even with air fully closed (as closed as you can get it on these models). If this is ok, then great, but I'm looking for answers from those more experienced. Thanks!

Every stove can be a little different. Chimney height, chimney cleanliness, outside air kit, wood moisture and other factors can alter the stove efficiency.

Page 15 of the manual:
Use a Stove-top Thermometer
Determining the primary air setting for the best overall performance for your particular needs and installation will be established over time and experience. Each installation has unique characteristics that affect stove performance. You should use a stove-top thermometer to monitor the status of the fire. Place the thermometer on the stove top, centered to one side or the other. Generally speaking, once the stove temperature has reached 400°F - 600°F (204°C -316°C), the air control may be set in a mid-range position
to allow adequate oxygen to support efficient combustion throughout the burn cycle. You can also monitor stove performance through the window. Peak combustion efficiency occurs when exhaust gas is burned at the baffle in the top of the firebox. This is apparent as rolling yellow-orange flames appearing at the
secondary air ports in the underside of the baffle plate and forward tube. At this stage, little or no smoke will be visible exiting the chimney.

Hope that helps
