Figures are for the SP80E (HSPE80U1M) only. The two-circuit amperage and wire size apply when the heater is wired across two separate supply circuits — see the circuit diagram in the Installation and Operation Manual. A licensed electrician must size the breaker and confirm every value against that manual before wiring.
Safety Distances
| Minimum clearance | Harvia Spirit SP80E (HSPE80U1M) |
|---|---|
| Heater to side wall | 3.2" (80 mm) |
| Heater to combustible material, left and right | 3.2" (80 mm) |
| Heater front to combustible material | 3.2" (80 mm) |
| Top of heater to ceiling | 35.5" (900 mm) |
| Floor to underside of heater (mounting height) | 4" – 12" (100 – 300 mm) |

Harvia states the same clearances at every Spirit output, so these do not change with the heater's kW rating. The last two rows are the total protected zone — cabinet plus the 3.2" clearance on each free side (385 + 80 + 80 = 545 mm wide, 334 + 80 = 414 mm deep). Neglecting these values causes a risk of fire; confirm against the Installation and Operation Manual linked below before building.
