Set aside the temp sensor housing for now. 4. Turn the heater on it’s back and remove the bottom cover to expose the temp sensor. 5. Remove the temp sensor and carefully uncoil the sensor cable that is attached to the sensor. Heater Fence 6.
9. At this point, it’s time to switch on the heater, so turn on the breaker. There is a non-toxic coating on the heater elements, and the purpose of this preliminary heating stage is to burn that coating away. It is normal for smoke to appear, so keep the door open to prevent it from leaving a black residue on the ceiling. Run the heater for 3-5 minutes or until it stops smoking, and then turn it off and allow the elements to cool.
Cedar Trim Sensor Cover 11. Mount the metal temp sensor housing vertically on the wall and 12” to the right or left of the heater. For barrel-shaped saunas: Mount the housing so that the top is 4.5” below the upper horizontal wall support. For a box-shaped saunas: Mount the housing 15” down from the ceiling. 12. Conceal the temp sensor by mounting the sensor cover. Place the cover over the temp sensor and mount with a single screw that is provided.
TROUBLESHOOTING 1. If sauna heater does not operate after initial installation and wiring Check breaker to be sure it is on. Be sure timer is set properly and is “on”. (Step #9) 2. If sauna heater operates but sauna room does not come up to temperature Check to be sure breaker is on. Check to see that the timer has not wound down. If so, reset. Are the stones placed loosely around the elements? Stones packed too tightly can re strict airflow and reduce heating capacity.
