What's Included
In the Box
Sauna Stove, Installation and Operation Manual

Sauna stones are not included, and the stove must not be fired without them.

Required to Operate

A wood stove is only part of the job. None of these come with it.

Sauna Stones
A minimum of 132 lbs. Narvi does not supply stones through this range, so use split-face or rounded sauna stones from another maker — we stock several. Flue & Chimney
A flue system rated for a solid-fuel appliance, plus the roof or wall penetration hardware. Narvi makes a modular flue that fits these stoves. Clearances
The distances to combustible surfaces given in the installation manual, or a protective wall to reduce them. A Non-Combustible Base
A hearth or installation base under the stove. Narvi makes an adjustable one. Sauna Stones We Stock
Harvia Split-Face Stones, 5-10 cm, Harvia Split-Face Stones, 10-15 cm, Harvia Olivine Rounded Stones, 5-10 cm, HUUM Sauna Stones, 5-10 cm

Narvi tests these stoves to EN 15821 and CE marks them. It publishes no UL, ETL, ULC or CSA listing, and no dealer we checked claims one. Check what your inspector and insurer require before you install.

Clearances to Combustible Materials

The minimum distances Narvi publishes to unprotected combustible surfaces. Measure these before you frame the benches — they decide where the stove can physically go.

Side
11.8" (30 cm) Rear
7.9" (20 cm) Front
19.7" (50 cm) Ceiling
50.0" (127 cm) Protective Wall
Fitting a Narvi protective wall shield halves the side and rear clearances. Floor
A concrete slab of at least 50 mm, or the Narvi installation base. The base is required on any combustible floor and over underfloor heating. Narvi also calls for a metal sheet extending at least 100 mm past each side of the door and 400 mm in front of it.

Narvi's product page and its own installation manual give different side clearances for this stove. The larger figure is shown here. The installation manual supplied with the stove governs — follow it.

Narvi lists these as options for this stove.

Installation & Use Notes
  • Fit the flue and the clearances above before you light it. The flue socket is 119 mm and exits top or rear, so a US-size adaptor is usually needed — Narvi makes one.
  • Cut firewood to about 33 cm (13") and around 5 cm thick, and never fill the firebox past two thirds of its height.
  • Load the stones loosely by hand so air moves between them. Never fire the stove with an empty stone space.
  • Burn dry, split firewood only. Wet wood tars the flue and makes poor steam.

Limited Warranty - Narvi

FAQs
Are stones included with the Kaamos 20 (21 kW)?
No. Narvi specifies a minimum of 132 lbs and supplies none in this range, so budget for stones as a separate line. The stove must never be fired with an empty stone space. Is it UL or ETL listed?
No. Narvi publishes a CE marking, which is the European conformity mark, and no North American listing. Some jurisdictions and insurers require a listed solid-fuel appliance, so confirm before you buy. Do I need a chimney, and what size?
Yes. The flue socket is 119 mm (4.7") and can exit from the top or the back, so most US installs need an adaptor to standard pipe. Narvi makes a modular T600-class flue system and the adaptor; neither is included with the stove. Allow at least 11.8" (30 cm) to the side walls and 50.0" (127 cm) to the ceiling.
