Jotul Oslo ... To damper or not to damper ?

In my old house I had Waterford cast iron stove (1989) which never had a flue damper or problems with overfiring. I hope to have my Ivory Jotul Oslo delivered in about two weeks. It's been on backorder for two months but given me plenty of time to build a nice hearth. Any recommendations (pros or cons) for adding a damper?

I used Simpson Dura-plus triple wall pipe for the class A chimney. I plan to use Simpson Dura-vent double wall DVL stove pipe from the stove to the chimney support box. The total pipe length is about 20 feet in a completely vertical installation. I'm at high elevation ~7000 ft. Current temps have ranged from the mid-50's to the mid-teen's.

Getting tired of cold feet!

Thanks,
Jeff

Thanks for the input. I'll forgo the damper until I see how the stove burns. I was a bit worried about Oslo posts where folks had a hard time controlling the burn rate and I'd rather not burn my new house down or crack/warp the new $3k stove. I plan to be extra careful not leaving any of the doors open (especially the ash pan door) while unattended.

Do you recommend both a stove top and stove pipe thermometer? I'm a bit concerned about drilling a hole through the double wall pipe for the temperature probe.

Thanks, Jeff
