A. 3-2-10 Rule. Residential code says you need to be a minimum of 3′ above the penetration point and 2′ above anything within 10′.
A. Yes! The stock legs, tall legs and wood storage stand all have mounting holes for securing to the floor. The legs come with hardware installed in the legs that are for leveling the stove. This plate / hole that is used for leveling can also be used to bolt / secure the stove to the structure.
A. We recommend that any chimney installed on a structure that moves (RV, bus, van, tiny house on wheels, etc) be constructed so that the chimney can be removed for travel. This provides lower clearance, as well as protects the chimney from being damaged by branches or road debris while in motion. See this article on detachable chimneys.
A: Standard installations require 18” clearance on the back and 16” on the sides. This can be reduced by 66% with the use of a heat shield (non-combustible material with 1” air space behind it and around the perimeter).
A: 3” flexible aluminum pipe and a hose clamp works well, and can be sourced locally at the hardware store. Alternatively, if you prefer a more rigid pipe, our 3″ single-wall stovepipe female end fits nicely over the inlet of our direct air box.
A: No, but we do plan to complete the UL certification in the near future.
A: All of our standard Dwarf stoves have drafted well with straight 40” chimneys, so we’re confident that you can design a successful flue system for even the smallest spaces.
If you are using the oven accessory on the Dwarf 5kW (the Cookstove Combo), you may need 80" or more height for optimal draft.
If you have non-vertical sections in your chimney (i.e. you’re using 45s or a wall exit), you may need significantly more height to produce sufficient draw. Connecting a small stove to a larger chimney with an adapter can also interfere with good draw. If you’re not sure whether your flue design will work, send us an email at email@example.com and we’ll be happy to help.
A: If you are installing in a vehicle, you’ll most likely want our RV/Bus kit. If you’re installing in a tiny house or cabin, you’ll most likely want our Tiny House Roof Exit kit. If you can’t use a roof exit, we have a Tiny House Wall Exit kit available for stoves with 4” and 5” flues. Check out our handy roof install worksheet to help you decide how much single wall pipe you need in addition to your kit. Most people also order some extra insulated pipe to get enough height above their roof. Residential code says the top of the flue should be 3′ above penetration and 2′ above anything within 10′. If you want to maximize the cooking area on top of your stove by using the rear flue exit, you’re going to want a rear exit kit.
If you need help deciding which parts to order, send us an email at firstname.lastname@example.org and we’ll be happy to help.
A: We don’t want you to have to buy extra parts that you don’t need, so we only included items in the kit that most everyone will need. Since every install is different, most people will need different amounts of single-wall and double-wall pipe to complete their installations. You can purchase extra pipe separately from your kit.
A: The 3kW stove doesn’t usually draft well with a wall exit. If you’re installing a stove with a 3” flue, we recommend keeping the flue as vertical as possible to create the best draft. Larger stoves like the Dwarf 4kW and Dwarf 5kW do work well with a wall exit, so we offer wall exit kits in 4” and 5”.
A: Sizing a stove to your space is going to depend on the size of your space, how well your space is insulated, the climate where you’re spending the winter, and how you intend to use your stove. A stove used for primary heat might be sized differently than a stove used primarily for ambiance. It’s generally better to run a small stove hotter and more efficiently than to underfire a larger stove, since underfiring your stove can cause creosote buildup in your flue.
A good place to start your design is to run your space through the BTU Calculator. For typical installations, we usually recommend a Dwarf 3kW for applications calling for 10-20k BTUs, a Dwarf 4kW for applications calling for 20-30k BTUs, and a Dwarf 5kW for applications calling for 30-40k BTUs. You might notice that the BTU numbers don’t match the kW ratings on the stoves — that’s because a typical installation includes some single-wall stovepipe which adds additional heat to the space.
If you need help deciding which stove will work best in your space, drop us a line at email@example.com and we’ll be happy to help.
A: The clearance requirements for the Dwarf stoves are listed on page 7 of the Dwarf Manual. You’ll need 18″ clearance from combustibles for the back of the stove and the single-wall stovepipe, 16″ from the sides of the stove, and 2″ from double-wall insulated stovepipe. You can tighten up those clearances significantly by installing a heat shield.
You’ll want to build a hearth under the stove at least 1/2″ thick, extending 8-12″ in front of the stove, and matching your clearances on the back and the sides.
A: A basic heat shield should be composed of non-combustible material (metal or cement board) and have at least a 1” air gap behind, above, below and beside the shield. A heat shield can be as simple as a piece of sheet metal with a 1” air gap behind and around. The “air wash” behind the shield is very effective but there has to be at least a 1” gap on all sides of the shield. Ceramic or metal spacers can be purchased for installing your shield.

A: Aside from basic tools to build your hearth and heat shields, and cut holes through your roof or walls, you may need:
- Chop saw or angle grinder with a metal cut-off blade for cutting pipe,
- Sheet metal crimpers for adding new crimps or adjusting existing crimps to make pipes fit together nicely
- Sealant to seal the roof boot to your roof. RTV silicone works well for this. If you’re installing in an aluminum trailer like an Airstream, Sikaflex 221 or Trempro 635 can be used instead.
- Stove gasket cement to attach the flue to the flue flange. Watch this video to see how that’s done. The rear exit tee can sometimes be a looser fit than the straight pipe, so I prefer to use this cement instead for a rear exit.
Installing a wood stove is a moderately advanced DIY project, so give yourself plenty of time, be patient and thorough in your work, and ask for help if you need it. Feel free to contact us with any questions you have about your installation.
A: Pellet pipe is typically constructed of zinc galvanized steel. The zinc coating can gas off at temperatures around 550 degrees F. Small wood stoves are easily capable of producing temperatures in excess of 550 degrees F at the flue. Since zinc gas is toxic if inhaled, this is an especially big problem in a small, poorly ventilated space, like almost any space were you would consider installing one of our stoves. Solid fuel rated flue pipe is constructed of stainless or carbon steel with high-temperature paint, no zinc coating, and is rated to temperatures in excess of 2,000 degrees F.
A: No, not yet. Most people build a custom cabinet for their 3kW stove to sit on top of using the standard legs.
A: No, not yet. We are still in a R&D phase for this option.
A: Yes, direct air is available. No, it’s not usually required. A wood stove exhausts air outside, so it wouldn’t deplete the oxygen in your small space the same way that a catalytic propane heater might. However, if your space is very airtight, the stove might not draft well without a direct air kit. Also, if you’re trying to keep your heating as efficient as possible, feeding the stove with outside air could help keep your heat in the house, rather than sending it up the chimney to be replaced by cold outside air leaking in.
A: The Dwarf 3kW and 4kW aren’t big enough to make a useful oven accessory. The footprint of the stove is so small that you wouldn’t be able to fit a useful sized pan inside of it. If you want to bake on top of a 3kW or 4kW stove, we recommend using a dutch oven. Be sure to get the rear exit kit with your flue system so that you can use the entire top cooking surface.
A: Yes, but it brings the top of the oven (also a cooking surface) to about 47″ off the ground. With the standard legs, the top of the oven is about 38″ off the ground, around the same height as a standard kitchen counter. If you intend to use the top of the oven as a cooking surface, it can be awkward to use at 47″ high.
