Tiny Woodstove Installation

The following is for a recreational trailer, using some specs from the Marine Stove website:

The “chimney must be at least 3′ higher than the highest point where it passes through the roof,” and through a listed metal prefabricated chimney, to, “at least 2′ higher than the highest part of the roof or structure that is within 10′ of the chimney, measured horizontally.” So plan to take it off when traveling and replace it with a cap.

“When a metal prefabricated chimney (Type HT per UL 103 or ULC S629) is used, the manufacturer’s installation instructions must be followed precisely. You must also purchase (from the same manufacturer) and install the ceiling support package or wall pass through, the “T” section package, the firestops (when needed), the insulation shield, the roof flashing, the chimney cap, etc. Maintain the proper clearance to the structure as recommended by the manufacturer. This clearance is usually a minimum of 2″, although it may vary by manufacturer or for certain components.”

Stovepipe – 4″ single-wall stovepipe is recommended from your the Little Cod to the ceiling (crimped end down).”

Pipe Damper 4″ (no 3″) made of cast iron & steel. Install this 30″ above your Little Cod stove. This is your stove’s “gas pedal”. Running a stove without a damper is unsafe. You would also go through wood in a hurry without one!”

Stove Surround (instructions are for the “Little Cod” stove:

Shield Construction Specifications:

1) Minimum space between shield and combustibles: 1” – 25 mm

2) Minimum clearance along the bottom of shield: 1” – 25 mm

3) Maximum clearance along the bottom of shield: 3” – 75 mm

4) Minimum clearance along the top of shield at ceiling: 3” – 75 mm

5) Edge clearance for ceiling shields: 3” – 75 mm

6) Adhesives used in shield construction must not ignite or lose adhesive qualities at temperatures likely to be encountered.

7) Mounting hardware must allow full vertical ventilation.

8) Mounting hardware must not be located closer than 200 mm
(8 in.) from the vertical centre line of the appliance.

9) Mounting hardware which extends from the shield surface into combustibles may be used only at the lateral extremities of the shield.

After reduction, clearances shall be not less than 12 in. (41Cm) to combustible walls (for the Little Cod) and not less than 18 in. (76Cm) to combustible ceilings.

Insulation material used as part of a clearance reduction system shall have a thermal conductivity of 1.0 (Btu-in.) / (ft 2 -hr-°F) or less. Insulation board shall be formed of noncombustible material.

K-FAC 19 insulation board is manufactured by Thermafiber TO ORDER PLEASE CONTACT: Foundry Service @ 562-945-6511 / foundryservice.com / Speak with Dave or Blake.”

Materials and Accessories

Furnace Cement is a ready-mixed, high-temperature silicate cement with a finely ground smooth consistency. This material has the appearance and texture of fine mortar, and will withstand temperatures to 2000°F. Can be used anywhere a high-temperature resistant adhesive is needed. Especially for bonding and sealing metal to metal joints. When air dried and cured according to directions, this cement becomes as hard and durable as firebrick. Primarily, a metal to metal sealant that may be used for filling joints between masonry and metal as this material strongly resists separating from the metal, unlike so many similar products.”

RTV High-Heat Silicone Sealant (Clear). Good for caulking the joint between the bronze deck iron and the wood leveling block.”

Make your own firebrick. Originally developed for use in blast furnaces, castable refractory cement has exceptional strength and abrasion resistance. It’s ideal for casting into custom shapes to replace worn-out firebrick. When the dry material is mixed with water, it chemically sets and dries brick hard. It can be cast in irregular shapes or as a solid stone bed. 12.5 lbs. casts a block 12″x12″x11/4″, or 120 lbs./ cu. ft.”

Chimney Brush (3″ or 4″) w/ 10′ flexible handle & ball tip. Makes cleaning pipes a simpler job. Flexible shaft “snakes” brush through 45’s & 90’s. Cut handle down to suit your particular pipe run. [3″ – #17409, 4″ – #17410].”

The Alcohol “Drop-In” Burner Here’s a handy item that will allow you to boil water or cook on top of your stove in the warmer months. No need to take up valuable counter space with another burner device while your woodstove sits idle. The DROP IN BURNER literally drops into the stove top and burns plain denatured alcohol. The burner element is self pressurizing(minimal) and since it is located down in the cast bronze burner housing, there is little worry of spilling fuel. The “DROP IN” fits all NAVIGATOR stoves. On a 2 oz. filling it will run for 20 min. We found that it takes 8 min to boil a liter of water. Running in simmer mode, the burn time is easily doubled. To refill is simple using the included fuel bottle. Longer cook times are only interrupted by the time it takes to add another 2 oz. of fuel. Then during the same day when you’d like to have a fire in the stove to warm up, the “DROP IN” can be taken out in a split second and a wood fire can be started. Pretty slick, eh?”

Okay, it’s me now… and here is my disclaimer: This is what I plan to do. I am not recommending it to anyone else. You are responsible for your own plans.

I plan to put the stove on a bench so that I can store wood under it. That also means a shorter stovepipe. I don’t plan to hang the stove pipe from the ceiling or roof but to stand the weight of it entirely on the stove. For travel I will take the chimney off (most of the part above the roof, leaving just the stub coming from inside), and put a cap on the stub. Installing the stovepipe with a rubber grommet at the roof will prevent lateral movement.

Colorado Cylinder Stoves

  • Mesa Stove Kit (they will give you a 5″ damper instead of 4″ if you ask, and credit you $10 or so if you don’t want the telescoping stovepipe normally in the kit).
  • 4″ to 5″ Adapter (I can’t find any 4″ chimneys, so I have to go to 5″).
  • 2 pieces of 5″ Stovepipe (enough to go a few inches above the roof).

Woodstove Pro

See the Selkirk Superpro system Tech Sheet for detailed specs.

  • Rain cap for 5″ chimney: SPR5DRC
  • Spark arresting screen (is this needed, or included in the cap?): JSC5SPAR
  • T-Plug (to cover pipe stub while traveling): J51TPI
  • Chimney, 5″ x 24″: SPR5L24
  • Storm Collar, 5″ (I.D. 7″, Height 4 1/2″): 5/6T-SC or JSC5SC-1
  • 5″ adapter from single-wall pipe to chimney (12″ high): JSC5ASE
  • Rafter radiant heat Shield: http: JSC5RRS needed in addition to my sleeve, below?
  • (7″ single-wall sleeve for 5″ single wall pipe coming through “attic” and roof boot is purchased below. I will wrap fiberglass? between the two as a spacer)
  • Trim Plate, 5″ (extra wide so it can be tight around 5″ pipe but hide the 7″ sleeve, and it will not be attached to any woodwork but only to the pipe system): 5T-TPS

Amazon

  • Rubber Chimney Boot – This should accommodate flexing during road travel. (Amazon has this cheapest.)

Woodstove Outlet has heat shielding for 5″ single-wall stovepipe, and other supplies.

  • HomeSave Singlewall Stovepipe Shield, for 5″-8″ pipe – to protect the wall from radiant heat. My closest “wall”, about 6″ from the stovepipe, will be a  ~1/2″ thick concrete panel painted with heat resistant paint and mounted with air flow under, behind, and above it.
  • 7″ x 36″ single wall pipe for sleeve through attic space and roof grommet (I need ~30″).
