Some Questions Answered
Can the Griddle Be Used Safely Indoors With Proper Ventilation?
No, you shouldn’t use it indoors even with ventilation requirements met; propane tabletop griddles are designed for outdoor use. You’ll expose yourself to carbon monoxide and combustion risks that typical home vents don’t fully mitigate. Compared to indoor-rated gas ranges, this unit lacks indoor safety certifications and sealed combustion. If you need indoor griddling, choose an appliance labeled for indoor use with proper ventilation and CO alarms for safer operation.
Are Replacement Griddle Plates Available From the Manufacturer?
Yes — replacement griddle plates are available from the manufacturer or authorized dealers, though stock can vary. You’ll want to check replacement availability before buying; contact ONLYFIRE for current parts and confirm compatibility with your model. If a plate fails, manufacturer warranty may cover defects within one year, but normal wear likely won’t. Comparing seller warranties and third-party parts can save time and money on long-term maintenance.
Does the Unit Support Natural Gas Conversion Kits?
No — it doesn’t support natural gas conversion kits out of the box. You’ll be limited to propane unless the manufacturer offers an explicit conversion accessory; using third‑party kits risks safety and voids the warranty. If you need natural gas, compare full‑size grills or models designed for conversion: they have certified kits and fittings. Contact ONLYFIRE GRILLS to confirm options or request a factory-approved conversion before modifying your unit.
How Compatible Is the Grease Tray With Aftermarket Liners?
You’ll find liner compatibility good but not perfect — the grease tray fits common aftermarket liners sized for compact griddles. You’ll want to measure width/depth first; aftermarket fitment varies by brand, and some thicker or gusseted liners won’t sit flat. Compared to full-size griddles, this tray accepts most universal liners, but expect occasional trimming or folding for a snug, drip-free fit. Always test before heavy use.
Is a Spare Electric Igniter Sold Separately?
No, a spare electric igniter isn’t listed as sold separately; you’ll need to contact ONLYFIRE or third-party parts sellers. Expect a replacement cost in the $5–$25 range for generic igniters, higher for OEM units and shipping. You’ll want to compare dealer quotes versus aftermarket parts: dealers may offer exact-fit reliability, while aftermarket options are cheaper but might need more installation effort and occasional adjustments.
