The Harvia 136 and 136E are electric sauna heaters designed for heating sauna rooms to bathing temperatures. The 136 model features an integrated timer and thermostat, while the 136E model requires a separate control unit.
Stone placement
Proper stone placement is critical for safety and performance. Use only stones approved for sauna heaters (peridotite, olivine diabase, olivine, or vulcanite) with a diameter of 5–10 cm. Wash dust off before use. Do not wedge stones tightly between heating elements; they should support each other without putting weight on the elements.
Operation
Heater 136: Use the timer to set the on-time (0–4 hours) or pre-set time (0–8 hours). Use the thermostat to set the desired temperature.
Heater 136E: Controlled via a separate control unit. Refer to the control unit's specific manual.
Installation
The heater must be installed by a professional electrician in accordance with local regulations. Ensure the sauna room is properly insulated and ventilated. The heater must be wall-mounted using the provided rack. Ensure safety distances are maintained as specified in the manual.
Maintenance and Troubleshooting
Rearrange stones at least once a year to maintain optimal heating and prevent overheating. If the heater does not heat, check the fuses, connection cable, and ensure the overheat protector has not tripped. The overheat protector reset button is located inside the electrical box.
