Congratulations on your purchase of your Scandia Ultra-Sauna gas fired heater!
Since 1964 Scandia Manufacturing has been making the best sauna heaters in the industry. Each heater is
hand crafted and individually made by an expert technician. They are not mass-produced; we consider each
heater a work of art.
To ensure your satisfaction with our heater we suggest you read through this guide and familiarize yourself with:
1. Installation Instructions
2. Gas Heater Component List
3. Warranty Information
4. Troubleshooting Guide
**Safety First**
You must consult a certified plumber or HVAC professional to assist you with regulating gas line pressure, installation
and connection of your Scandia Ultra-Sauna. Self-installations will void your warranty.
When you receive your heater you should inspect it within 48 hours to verify all parts, materials and instructions are
there. Scandia is not responsible for replacing or warranting items that are not reported within 5 days of receipt of
your shipment.
*If your shipment is damaged please retain all packaging and call us im-
mediately*
Prior to installation, the installer (certified professional) should check all connections and parts to ensure proper fitting.
These items may have come loose in shipping. You can rest assured knowing that your unit was fired and tested in our
production facility prior to shipping to ensure proper working order. Loose connections and/or improper installation
are the most common reasons for your unit not firing up right away. Do not call the manufacturer until a licensed
professional has checked to ensure proper connection.
The heater must be installed with a heater guard rail – see instruction for proper clearances.
Your heater comes standard with a flue cap (for through-wall venting) or an elbow and draft-hood (for through-ceiling
venting). We recommend one 90 degree turn in venting if needed as additional turns can cause heat to become
trapped in the unit itself and result in improper functioning of the heater. Straight through the wall venting (flue cap)
typically does not use an elbow and it is not recommended unless approved by a certified professional. We highly
recommend consulting with a venting specialist or engineer if you are planning venting runs longer than 7 ft as this
may require a power vent.
Scandia is not a venting company. Please consult a venting specialist for your venting needs.
Caution signs are included for your safety.

GAS CONSUMPTION INFORMATION
FOR SCANDIA ULTRASAUNA
The gas consumption for the Ultra-Sauna heater can be different for every
room and will vary depending on the following conditions:
• Properly built sauna room
• Seven foot ceiling height
• Adequate room insulation
• All cedar wood interior
• Tightly fitting door
• Outside (for outdoor saunas) temperature 50 def F or higher
• Correct heater sizing
• Correct heater venting configuration
THE HEATER WILL PERFORM AS FOLLOWS:
• Heat the room to temp (170 deg F) within 10-15 minutes
• After reaching temp (with minimal door traffic) the heater should maintain that
temp on a 50% on/off basis.
• A one hour run –time should result in 25-40 minutes of heater run time.
• Door traffic, outside temp and other conditions listed above will influence efficiency.
CALCULATION NOTES TO REFERENCE AGAINST LOCAL UTILITY PRICING:
1 BTU = 0.03 Watt hours
100,000 BTUs = 1 therm
Please provide this information to your local gas supplier and they will be able to provide you with the gas
consumption calculations for your sauna room.
Sincerely,

DAILY
• Wait for the sauna to cool before entering the sauna to conduct a cleaning
• Use a bucket of warm water with a mild detergent (a liquid soap is sufficient) and clean
sponge or rag to wipe the bench surfaces.
• Do not use petroleum-based detergents. They can discolor your wood and will leave a residue
which could emit irritating fumes.
• Wet mop the tile or cement floor.
• If something unpleasant other than ladled water is applied to the heater’s rocks, clean them after
they have completely cooled. Soak them in a soapy (light detergent) mixture of warm water. Wash
off with a sponge, then rinse in clean water. Allow the rocks to dry, then re-apply rocks to the
heater trough. Clean the heater and trough of the foreign substance. Gradually build heat in the
sauna to totally dry the rocks.
WEEKLY
Take a rag and soapy water and wipe down benches and heavily used wall areas. (Do not take hose to sauna at
any time.) Inspect benches for broken boards, tighten loose screws and make sure benches are firm.
There should be a thermometer/hygrometer in the sauna room at all times to show temperature and humidity for
members safety.
EVERY 6 MONTHSONE YEAR (depending on usage)
Take an orbital sander and lightly sand benches and walls to take off thin layer of discolored wood. Directly
after use Scandia Essential Wood Oil and apply to sanded area. Wood oil comes in gallon jugs and can be
purchased through Scandia’s website.
WEEKLY
Remove and inspect all stones and clean the trough. If a stone is broken throw it away. If broken stones are al-
lowed to remain inthe trough they will break down into a sandy grit. That grit will eat a hole in the stainless steel.
This damage is not covered by the warranty.
MONTHLY
Wipe down the heater shell to clean up any water stains.
NEVER EVER TURN A HOSE ON THE SAUNA TO WASH IT DOWN.
IT WILL DAMAGE THE HEATER’S ELECTRIC COMPONENTS.
