Narvi NC Black Wood Burning Sauna Heater | Dundalk Leisurecraft

The Narvi NC Black Wood Burning Sauna Heater is a high-efficiency Finnish wood-burning sauna stove renowned for its timeless design, clean lines, and superior thermal performance. Designed and manufactured in Finland, the NC series combines a minimalist black-painted casing with a robust cast-iron glass door and an elegant steel top frame surrounding the stone compartment. Engineered for authentic off-grid sauna enthusiasts, it provides an uncompromised Finnish bathing ritual powered entirely by natural split firewood.

What sets the Narvi NC stove apart is its novel fire chamber architecture. This advanced design facilitates highly efficient, environmentally friendly secondary combustion that complies with strict CE marking standards without consuming excessive amounts of firewood. Its expansive stone compartment accommodates substantial rock loads (up to 176.4 lbs depending on model size), creating deep thermal retention that delivers an even, long-lasting, and soft löyly steam experience. Outfitted with adjustable leveling feet and dual flue routing (allowing both top and rear chimney connections), the Narvi NC Black effortlessly elevates both traditional and modern outdoor saunas.

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.

Installation Manual

(Note: Natural sauna stones, protective hearth floor plates, and chimney flue pipes are sold separately).

• Initial Outdoor Paint-Curing Burn: Before mounting the stove permanently inside your sauna cabin, conduct an initial outdoor test burn with split wood. This cures the high-temperature protective black paint and burns off manufacturing oils safely outside the sauna room.

• Hearth Base & Clearance Adherence: Position the heater on an approved non-combustible base (such as a masonry floor or certified steel stove hearth plate). Strictly follow manufacturer minimum clearances to combustible walls: 5.9" side, 5.9" back, 19.7" front, and 47.2"–49.2" top.

• Stone Loading & Convection: Wash all sauna stones thoroughly with fresh tap water to remove surface minerals prior to stacking. Place larger stones loosely around the lower firebox and smoke channels, layering smaller stones at the top. Never pack or jam stones tightly into the upper basket; free convective airflow through the rocks is essential to heat transfer and proper draft.

• Firewood Selection: Burn only dry, natural, seasoned firewood logs. Never burn pressure-treated lumber, painted wood, driftwood, plastics, garbage, or charcoal, as toxic fumes and extreme localized temperatures can warp the fire chamber and void coverage.

• Ash Drawer Maintenance: Empty cooled ashes regularly from the bottom ash box before starting each burn session to maintain unhindered airflow intake through the fire grate. Store cooled ashes strictly in a metal container with a tight lid.

• Flue & Chimney Sweeping: Inspect the chimney connection and flue pipes periodically for creosote and soot accumulation. Have the chimney swept at regular intervals to maintain drafting efficiency and prevent chimney fires.

• Glass & Outer Surface Cleaning: Clean the ceramic glass door window only when completely cool using a damp cloth dipped in fine wood ash or a dedicated wood stove glass cleaner. Wipe down exterior matte black steel panels with a soft, dry cloth. Never splash cold water onto the glass door while hot.

• Löyly Water Application: Pour clean, fresh domestic tap water gently over the hot rocks using a long-handled sauna ladle. Never use pool water, chemically treated spa water, or salt water, which corrode the steel firebox and stone basket.

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

• Warranty Exclusions: Consumable wear components—including the ceramic glass door, ash grate, deflector plates, and sauna stones—are excluded from warranty protection. Damage caused by unapproved fuels, improper outdoor curing, lack of an approved hearth foundation, or failure to observe required combustible clearances voids warranty coverage.

• 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 crating 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 transport logistics, freight units are generally non-returnable. If an authorized factory return is 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. Units must be completely uninstalled, unfired, and secured in their original wooden crate/packaging.

• Transit Damage Protocol: Thoroughly inspect the crate upon arrival. Note any visible carton tears, pallet damage, or punctures directly on the driver’s Bill of Lading (BOL) and report missing or damaged components 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.
