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.
