Fitting Tips

  1. Cool & clean: Only work when the stove is cold.
  2. Dry fit: Test-fit glass, bricks and baffles before adhesives.
  3. Adhesive sparingly: Thin, continuous bead for rope seals.
  4. Re-commission: Light with Firestarter and run a short, hot burn to set seals.

Care & Prevention

  • Ignition: Start hot and clean with Firestarter to reduce tar and fouling.
  • Fuel: Burn dry hardwood only (≤20% moisture).
  • Air settings: Avoid long slumbering; aim for lively, clean flames.
  • Seasonal check: Inspect ropes, baffles and bricks pre-winter.

FAQs

How often should I replace the door rope seal?

Typically every 12–24 months, depending on use. If paper slips easily around the closed door, the seal is due.

My glass blackens quickly—do I need new parts?

Often ignition technique/fuel is the culprit. Start clean (Firestarter), use dry wood, and open air fully for 10–15 minutes.

Can I run the stove with a cracked fire brick?

Hairline cracks may be tolerable short-term, but missing/broken sections should be replaced to protect the stove body.

Do I need a professional for fitting parts?

Many parts are DIY-friendly, but if flue/liner work is needed, book a HETAS-qualified technician.
