Narvi Kaamos Wood Burning Sauna Heater | Dundalk Leisurecraft

The Narvi Kaamos Wood Burning Sauna Heater is a high-efficiency Finnish wood-burning sauna stove designed and manufactured in Finland. Drawing its name from the Finnish word for "Polar Night," the Kaamos features an angular structure finished in a durable matte black exterior that pairs minimalist Nordic aesthetics with robust off-grid heating power. Engineered for authentic sauna enthusiasts, it provides an uncompromised Finnish bathing ritual powered purely by seasoned firewood.

Built for decades of dependable service, the Narvi Kaamos is equipped with a sturdy 10 mm thick firebox ceiling, a hard-wearing cast-iron fire grate, and a full glass fire door hatch that casts a calming ambient flame across your sauna cabin. At the back of the heater, an integrated protective air deflector plate promotes a clean, efficient burn while keeping fuel consumption low. Its expansive stone compartment accommodates up to 132 lbs (60 kg) of natural sauna stones in the standard Kaamos 20 model (up to 176 lbs in the Kaamos 24), generating generous volumes of soft, enveloping löyly steam when water is ladled over the hot rocks. With adjustable leveling feet and top or rear chimney flue connectivity, the Narvi Kaamos integrates seamlessly into traditional barrel saunas and outdoor log cabins.

Important Shipping Notice: When purchased together with any Dundalk Leisurecraft sauna cabin or barrel kit, this heater ships free bundled directly inside the sauna's primary freight crate. If this heater is bought singularly as an individual standalone unit without a sauna, a flat $350 freight shipping fee will be applied at checkout to cover dedicated carrier handling and cross-border transport.

User Manual

Installation Manual

• Initial Outdoor Paint-Curing Burn: Before installing the stove permanently inside your sauna cabin, the heater requires an initial preheating fire outdoors to cure the heat-resistant protective paint and dissipate initial manufacturing odors.

• Installation Base & Clearance Compliance: Always place the stove on an approved, non-combustible base (such as a certified floor protection plate or masonry foundation). Strictly adhere to the minimum clearance to combustibles: 11.8" side, 7.9" back, 19.7" front, and 50" top clearance.

• Stone Loading & Airflow: Thoroughly rinse sauna stones with clean tap water before loading to remove fine mineral dust. Position larger stones loosely around the bottom and smoke channels, layering smaller stones at the top. Never force, pack, or wedge rocks tightly into the stone cavity; natural airflow through the stones is essential for proper heat transfer and draft performance.

• Firewood Selection: Burn only clean, dry, well-seasoned split natural firewood. Never burn treated wood, painted lumber, plywood, cardboard, trash, or unrefined charcoal, as intense synthetic heat or chemical fumes can damage the firebox and create safety hazards.

• Ash Removal & Pan Maintenance: Empty the bottom ash box regularly before starting each burn session to maintain unrestricted combustion draft through the bottom cast-iron grate. Dispose of cooled ashes strictly in a metal container with a tight lid.

• Chimney & Flue Inspection: Inspect the stove connection and chimney flue piping at least twice a year (or after every 50 operating hours) for creosote and soot accumulation. Clean the flue pipe regularly to prevent chimney fires.

• Glass & Exterior Care: Clean the cast-iron door glass once the stove is fully cold using a damp cloth dipped in fine wood ash (or an approved wood stove glass cleaner) to remove soot residue. Wipe down exterior matte black painted panels with a soft, dry cloth. Never spray cold water directly onto the glass door while hot.

• Löyly Application: Pour fresh domestic tap water gently over the hot stones using a long-handled sauna ladle. Never pour pool water, chemically treated spa water, or salt water over the stones, as harsh chemicals corrode the steel firebox and stone compartment.

• Manufacturer Warranty: The Narvi Kaamos Wood Burning Sauna Heater carries a 2-year manufacturer parts warranty matching Dundalk Leisurecraft supplier distribution terms (covering factory structural fabrication and material defects under standard residential use).

• Warranty Exclusions: Consumable wear parts—including the ceramic glass door, ash grate, fire deflector plates, and sauna stones—are excluded from warranty coverage. Damage resulting from improper outdoor curing, lack of an approved non-combustible hearth base, over-firing with unapproved fuels, uncertified chimney connections, or failure to observe required combustible clearances voids warranty protection.

• Order Modifications & Cancellations: Orders modified or canceled within 14 days of placement are processed free of charge. Cancellations submitted after 14 days or once the unit enters packaging and carrier dispatch are subject to a $350 administrative/order adjustment fee.

• Return Policy: Due to specialized carrier handling, heavy freight classification, and cross-border transit logistics, freight units are generally non-returnable. If an authorized return is explicitly approved in writing by the manufacturer, the customer is responsible for 100% of return freight shipping charges back to the facility plus a 20% restocking fee. Returned units must be completely uninstalled, unfired, and secured in their original wooden crate/packaging.

• Transit Damage Protocol: Thoroughly inspect the freight packaging upon arrival. Note any visible carton tears, pallet damage, or punctures on the driver’s Bill of Lading (BOL) and report missing or damaged parts within 30 days of delivery for complimentary replacement parts.

• Sauna Bundle vs. Standalone Freight:

  • Free Shipping with Sauna Purchase: When ordered alongside any Dundalk Leisurecraft sauna cabin or barrel kit, this wood heater is bundled directly into the main sauna crate and ships 100% free.

  • Standalone Purchase ($350 Flat Freight): If purchased individually as a standalone unit without a sauna, a flat $350 freight shipping fee is applied at checkout to cover dealer packaging, cross-border freight transit, and carrier surcharges.

• Service Area: Standard delivery covers the Contiguous United States. Shipments to Alaska, Hawaii, offshore islands, and remote/limited-access areas require a custom freight quote prior to dispatch.

• Delivery Method: Delivered curbside or to the property driveway threshold via standard commercial ground freight carrier.

• Address Rerouting: Any destination address change requested after the unit has dispatched from the warehouse incurs a mandatory $350 carrier rerouting fee.

• Shipment Refusal: Any unauthorized delivery refusal at curbside will incur a 15% restocking fee plus all applicable round-trip transit charges.
