Himalaya SL2 Series Sauna Heater – Frequently Asked Questions
1. What are the different models available and what room sizes do they accommodate?
Answer: The Himalaya SL2 Series offers two models:
- Himalaya SL2 7.0 (6.8 kW): Suitable for rooms with 21-175 sq ft floor area and 175-350 cubic feet volume
- Himalaya SL2 9.0 (9.0 kW): Suitable for rooms with 38-310 sq ft floor area and 310-500 cubic feet volume
Both models can accommodate ceiling heights from 75″ minimum to 96″ maximum.
2. What electrical requirements do I need for installation?
Answer: The electrical requirements vary by model and voltage:
Himalaya SL2 7.0:
- Single phase: 208V (32.7 amps) or 240V (28.3 amps) – requires 2 #8AWG wire with ground
- Three phase: 208V (18.9 amps) or 240V (16.4 amps) – requires 3 #10AWG wire with ground
Himalaya SL2 9.0:
- Single phase: 208V (43.3 amps) or 240V (37.5 amps) – requires 2 #6AWG wire with ground
- Three phase: 208V (25.0 amps) or 240V (21.7 amps) – requires 3 #8AWG or 3 #10AWG wire with ground
All installations must use copper wire only, suitable for minimum 90°C, and must be grounded per NEC requirements.
3. What are the minimum clearance requirements for safe installation?
Answer: Minimum clearances to combustible materials are the same for both models:
Both Himalaya SL2 Models:
- Front: 3.0″, Sides: 2.5″, Back: 2.5″, Top: 15.5″
- Temperature sensor: 3″ from ceiling directly above heater
- Minimum 44″ clearance from ceiling above heater
The Himalaya series has more compact clearance requirements compared to other Finnleo models.
4. How do I properly place the rocks in the heater?
Answer: Proper rock placement is critical for safe operation:
- Use only the rocks supplied with the heater (other types may void warranty)
- Rinse rocks with water before placing
- Place larger rocks at the bottom and smallest at the top
- Place rocks loosely to allow air circulation – packing too tightly may trip the high limit switch
- Rocks must completely cover all heating elements
- Never operate the heater without rocks in place
- Install the guard rail with provided screws after rock placement
5. How does the SL2 control system work?
Answer: The Himalaya SL2 features the advanced SaunaLogic 2 digital control system:
Control Features:
- Digital temperature display and control
- Programmable timer functions
- Remote temperature sensor (30-foot wire included)
- Can be mounted inside or outside sauna room
- Control size: 3⅜”W × 5½”H × ¼”D
Operation: The SL2 system provides precise temperature control with digital readout and programmable operation for consistent sauna experiences.
6. What should I do if the high limit control keeps shutting off the heater?
Answer: If the high limit control repeatedly trips:
- Immediate Reset: Turn control off, let heater cool, then press the reset button
- Check Rock Placement: Improperly placed or deteriorated rocks are the most common cause
- Rock Maintenance: Remove rocks smaller than 2″ pieces and ensure proper loose placement
- Ventilation Check: Ensure proper room ventilation and that vents aren’t blocked
- Sensor Check: Verify temperature sensor is properly mounted 3″ from ceiling
- Professional Service: If problem persists, contact qualified service technician
7. What maintenance is required to keep the heater operating properly?
Answer: Regular maintenance includes:
Daily: Inspect that controls and system are off at end of each day
Weekly: For daily-use saunas, wash down the room to keep clean and air fresh
Monthly: Wipe down heater with damp cloth to remove lint and dust
Annually:
- Remove and clean rocks, replacing any that are crumbled or smaller than 2″
- Inspect benches and supporting structures for deterioration
- Check all electrical connections
- Verify sensor mounting and wire condition
General Cleaning: Use soap or detergent in warm water with scrub brush for perspiration stains.
8. Can the SL2 control be relocated to a different position?
Answer: Yes, the SL2 control offers flexible mounting options:
Mounting Options:
- Inside sauna room on any wall
- Outside sauna room for convenience
- Control size allows for easy wall mounting
- 30-foot sensor wire provides flexibility for sensor placement
Installation Notes:
- Sensor must be mounted 3″ from ceiling directly above heater
- Control should be mounted at convenient height for operation
- All wiring must be performed by qualified electrician
9. What are the proper sauna room construction requirements?
Answer: Key construction requirements include:
Door Safety:
- No permanent locking or latch systems
- Use only magnetic catches, friction catches, or spring/gravity loaded closures
- Door must always open outward
- Mount WARNING placard on door at eye level
Electrical:
- No electrical receptacles inside sauna room
- All heaters and controls must be grounded per NEC
- CB Box can be inside or outside sauna room
Insulation & Structure:
- Minimum R12 insulation recommended
- Proper vapor barrier installation
- Install CAUTION placard on interior wall above heater
Other Requirements:
- No showers in sauna room
- Fire sprinkler systems must be rated for sauna temperatures
- Never use wood stain, seal, or preservative inside sauna room
10. What ventilation is required for the sauna room?
Answer: Proper ventilation requires approximately 6 air changes per hour:
Vent Placement:
- Fresh air inlet: Below the heater in the sauna wall
- Air outlet: Lower than upper benches, as far as possible from heater
Vent Sizing: Use these guidelines for minimum vent opening:
- For rooms under 31 sq ft: Minimum 9.3 square inches
- For rooms 31 sq ft or larger: 0.3 × floor area in square feet
Example: A 100 sq ft room would need minimum vent openings of 0.3 × 100 = 30 square inches each for inlet and outlet.
Special Considerations for Himalaya SL2:
- Higher power output requires adequate ventilation
- Sensor placement critical for proper temperature control
- Ensure ventilation doesn’t interfere with sensor readings
