Sunstar Warranty: 3 Years on the Burner Assembly
Sunstar backs the burner assembly on MGL and SGL series patio heaters for 3 years. Not all components get the 3-year coverage — the burner is the specifically-covered high-value component.

What you need
Step by step
Find your model and serial
Model (MGL35, SGL35, SGL50) + serial are on the data plate on the heater body. Photograph both before install — they can fade over 3 years outdoors.
Save your authorized-dealer receipt
Original purchase receipt from an authorized Sunstar/AEI dealer is required for a claim. Grey-market or unauthorized-reseller purchases don't carry the warranty.
Register with AEI
Call (949) 474-3070 or email [email protected] with model, serial, purchase date, and dealer name. AEI confirms registration via email.
Confirm residential use
Sunstar warranty terms assume residential use. Commercial installations may have different coverage — confirm at purchase for restaurant, hotel, or bar install.
Common mistakes
- Expecting whole-heater warranty for 3 years. The 3-year warranty specifically covers the BURNER ASSEMBLY. Other components (igniter, valve, cosmetic finish) have different coverage — check with AEI for specifics on your model.
- Running a Sunstar heavy-commercial without upgrading coverage. If you're running Sunstar heaters 10+ hours/day in a restaurant, contact AEI about commercial warranty coverage. Residential warranty terms can be voided by commercial-duty use.
Hands-on tips
- Keep the install photos — if the burner fails and AEI asks for proof of correct install, you have evidence that gas pressures and clearances were per spec.
- Claims through an authorized dealer are usually faster than claims direct to AEI. Keep your dealer's contact info saved.
