Questions people ask us

What do I need to order with the 3500?

Osburn lists a door overlay in black or brushed nickel as required, sold separately in the trims and fronts collection. The stove comes with its 130 CFM blower and a thermodisc. A rigid firescreen and a glass ash lip are options.

How much wood does it hold?

The 3.5 cu ft firebox takes logs up to 22" long, loaded across the width or the depth, for burns of up to 10 hours.

How much area will it heat?

Osburn recommends the 3500 for 1,000 to 2,700 sq ft. Climate, layout and insulation matter, so send us the details and we will talk it through.

Can it go in a mobile home or an alcove?

Yes, Osburn approves the 3500 for both, with the conditions in the manual. In a mobile home it needs a double wall connector, an insulated fresh air intake and anchoring to the structure.
