| Step | Key actions | |------|-------------| | | Verify floor load‑capacity, levelness, clearance (≥ 600 mm front, 300 mm sides, 900 mm overhead). Provide a dedicated fire‑rated enclosure if required. | | Foundation & anchoring | Concrete pad with vibration isolators; bolt the unit to the base per the mounting‑hole pattern (usually 4 M12 bolts). | | Fuel system | Install a fuel filter (5 µm) and priming pump; use a fuel line rated ≥ 10 MPa. Add a pressure‑relief valve and a fuel shut‑off valve accessible to the operator. | | Exhaust & ventilation | Connect the exhaust to a stainless‑steel, insulated pipe (minimum 150 mm diameter) with a back‑pressure ≤ 30 Pa. Ensure adequate fresh‑air intake (≥ 30 L/s per 100 kW). | | Electrical connections | Follow the wiring diagram (normally in the manual’s “Control panel” section). Use a dedicated MCCB, earth‑fault protection, and a 3‑wire + PE cable of appropriate cross‑section (typically 6 mm²). | | Water & heating circuit | Use a closed‑loop glycol‑water mixture if required; install pressure‑relief valve (≈ 2.5 bar) and air‑separator. Connect to the system’s header with flexible hoses or steel pipe, observing the flow direction arrow on the pump. | | Commissioning checklist | Verify all bolts, hoses, and electrical terminals; fill water, bleed air, check fuel pressure, and run a low‑load test before full load. |
