Most installation problems are not machine problems. They are site problems discovered on delivery day. Run this list before you order.
Gas
- Supply size. The HR-6KG burns 1.85 m³/h of natural gas; the HR-120KG burns 15.3–20 m³/h. Your meter and pipe must carry that plus everything else on site.
- Pressure and type. Natural gas and LPG need different nozzles and regulators. We set the machine for your gas at build — tell us which, and the supply pressure your utility quotes.
- Isolation and test point. A shut-off valve and a test nipple within reach of the machine. Your gas contractor will want them.
- Inspection. In most jurisdictions the installation needs a certificate before first firing. Book the inspection when you book the machine, not after.
Flue and ventilation
- Duct the exhaust outside, above roof level where local rules require it. A drum roaster moves a lot of smoke and chaff.
- A cyclone separator drops most of the particulate before the duct leaves the building — it also keeps the duct cleaner.
- Provide make-up air. A sealed room with an extractor becomes a vacuum and the burner misbehaves.
- Basements are possible but need mechanical supply and extract designed by somebody who has done it before.
Power
Have an electrician confirm the available capacity before the machine ships. A 36 kW element bank on a supply that cannot carry it is an expensive discovery.
Floor and clearance
- Level, load-bearing floor. The HR-20KG weighs 850 kg gross; the HR-30KG about 1.72 tonnes.
- Working space on the loading side, the discharge side and around the cooling tray.
- Room to pull the drum for cleaning, and to get a sack or a bin under the chute.
- If the machine is upstairs, check the floor loading with a structural engineer — this is not a domestic appliance.
First firing
Every machine is fired and run with beans before it leaves us, and the test log ships with it. On site, the first batch should be a cheap washed coffee: you are checking gas pressure, damper response and cooling, not chasing a profile.
What we send
Drawings, gas and power requirements, the test log and a commissioning checklist. Installation itself is done by your local contractor — we support it by video, and can quote on-site commissioning separately.
