FinSteam Sauna Gas Heater – Installation Requirements
When installing and using a FinSteam gas sauna heater, all installation requirements must be strictly followed. These requirements are mandatory and relate especially to ventilation, safety distances, and gas installation..
The heater must not be used in saunas where the ventilation requirements are not met.
The heater must not be used in saunas where the ventilation requirements are not met.
Before installation
Ensure that the heater is being installed in a sauna room or tent with ventilation that meets the required specifications.
Ensure that you have the correct gas type and low-pressure regulator suitable for the heater model. The heater must not be used with any gas type or pressure other than those for which it is designed
Before installation, verify whether national gas appliance regulations require installation by an authorized professional.
Ensure that the heater is not being installed in a completely airtight space.
Ensure that the heater and its components are in good condition and show no visible damage. Verify that no structural or other modifications have been made without authorization from FinSteam Oy.
Ensure that the heater is used only for its intended purpose and not as a space heater in residential areas or for any other purpose.
Introducing
FINSTEAM AURORA
AURORA combines modern design with improved adaptability for a wide range of sauna types.
1. Ventilation requirements
The ventilation must be natural (gravity) ventilation.
a gas heater must not be used in mechanically ventilated saunas.
There must be an unobstructed fresh air intake opening located near the heater.
Minimum air intake opening: 350 cm²
Examples: Rectangular openings: 200 × 175 mm or 250 × 140 mm. Circular opening: diameter Ø 210 mm
An exhaust air opening must be installed in the opposite upper corner of the sauna, either on the wall or in the ceiling.
Minimum exhaust air opening: 250 cm²
Examples: Rectangular openings: 200 × 125 mm or 160 x 160 mm. Circular opening: diameter Ø 180 mm
In permanent sauna buildings, we recommend using ventilation vents with an unobstructed airflow opening.
The air intake opening must be positioned so that the fresh air is always taken directly from outside air.
Sufficient fresh air supply can be achieved with one or two air intake vents.
The air intake vent should be adjustable and closable.
The exhaust air must be discharged directly to the outside air, not into the interior of the building or dwelling.
The exhaust air should preferably be implemented with a single exhaust air vent.
The exhaust air vent should be adjustable and closable.
Why proper ventilation is essential
A gas heater uses a significant amount of oxygen during combustion, which makes correct ventilation a critical part of both safety and performance.
Why proper ventilation is essential
A gas heater uses a significant amount of oxygen during combustion, which makes correct ventilation a critical part of both safety and performance.
Without proper ventilation:
Combustion becomes unstable
When combustion weakens too much, the ODS safety mechanism will automatically shut down the heater.
Unstable combustion can cause carbon monoxide (CO) levels to rise before the ODS safety mechanism shuts down the heater.
Adequate ventilation also ensures a comfortable, oxygen-rich sauna experience.
Proper airflow is not just recommended.
It is essential for safe and reliable operation.

IMPORTANT:
The ODS system is a safety feature and does not replace proper installation, adequate ventilation, or compliance with the manufacturer’s instructions and local regulations.
Gas Installation
Gas Hose Requirements & Safety
Use only CE-marked gas hoses, fittings, and connections in all gas installations.
Min. internal diameter 9 mm. Length must comply with local regulations (typically 1.2–1.5 m), securely fixed at both ends, kink-free, tension-free, and fully visible for inspection.
Protect the first 300 mm from the heater connection (e.g. with a 25 mm aluminium sleeve). Do not route under the heater, over sharp edges, or in contact with hot surfaces. Protect from mechanical damage and avoid placing in walkways without proper protection.
Place the gas cylinder outside the sauna in an upright position on a stable, level surface. Keep it away from heat sources and open flames, and always follow national regulations and local safety requirements.
Gas Cylinder Installation
Gas Regulator
Use only certified low-pressure regulators and ensure the pressure matches the heater category:
I3B/P: 30 mbar (butane/propane or mix)
I3P: 37 mbar (propane)
Incorrect pressure can cause excessive gas flow, incomplete combustion, CO emissions, and unstable performance. Always close the regulator valve after use.
Correct gas and low-pressure regulator installed
Ventilation openings confirmed
Required safety clearances met
Sauna stones properly placed inside the stone cage
This is an additional safety feature.
Not a substitute for proper ventilation, correct clearances, and full compliance with installation instructions.
