1. Quick Reference Electrical Specification Matrix

All ratings apply to North American standard single-phase residential electrical service (240V, 2-wire + equipment ground).

Table 1: 240V Single-Phase Specifications

\Note on SW80 Breaker: NEC 125% continuous duty rule requires 50A breaker in strict inspection jurisdictions.*

2. Critical Electrician Directives & Code Mandates

A. Supply Conductor Standards & Conduit Entry

• Conductor Material: Copper conductors only, rated minimum 90°C (194°F) (THHN/THWN).
• Conduit Rough-In: Terminate wiring using flexible metallic or liquid-tight conduit through the knockout located on the rear bottom electrical tray.
• Neutral Conductor: No neutral wire is connected. Operating voltage is straight 240V across terminals L1 and L2 plus equipment ground.

B. GFCI Breaker Policy

• Manufacturer Recommendation: Connect to a dedicated standard 2-pole thermal-magnetic breaker without GFCI. Standard Class A GFCI breakers (4–6 mA) are prone to nuisance tripping during startup due to minor atmospheric moisture absorption in the heating elements, which evaporates within 1 hour of heating.

C. Reversible Switch Position Feature

• Symmetrical Mounting Rack: The Wall features a separate mounting rack that determines the position of the illuminated control switches (can be mounted on either the right or left side to optimize access and rough-in conduit location).

3. Clearances & Spatial Layout (Safety Distances)

Table 2: Minimum Safety Clearances to Combustibles

4. Wall Mounting & Sauna Kit Timber Construction

The loaded operating weight of The Wall with 44 lbs of stones is ~75 lbs (34 kg).

B. Custom Indoor Builds

• If building an indoor custom sauna with 2x4 stud framing and cedar tongue-and-groove cladding, install horizontal 2x4 solid wood backing between wall studs at the mounting bracket height before nailing tongue-and-groove boards.

5. Control Operation & High-Limit Reset

• Illuminated Controls: The operating switches light up during operation for visibility in low-light sauna rooms.
• Thermostat Dial: Controls temperature setpoint.
• Timer Dial: 60-minute active run time with delay-start capabilities.
• High-Limit Reset: Located on the bottom of the heater. If an overheat occurs, allow the heater to cool completely and press the red reset switch.
