Real Fyre Fyre Spheres 4-Packs are boxes of four ceramic spheres for vented Real Fyre pan burners. Use them to replace spheres in a P45 set, or as a decorative top layer over glass on a PB pan burner. They come in 2, 3, 4, 5 and 6 inch, in Epic Black and Graystone, and the 4 inch also in Carrera Marble.
- In the box: four spheres of one size and color.
- Material: refractory ceramic, warranted for as long as you own them, indoors.
- For vented burners only. Vent-free G23 burners take their own sphere sets.
- Made by: R.H. Peterson Co. in City of Industry, California.
How many spheres does a burner take?
On a P45 pan burner the count is fixed, and Peterson warns that extra spheres can make it unsafe:
| P45 size | 4" spheres | 5" spheres |
|---|---|---|
| 18" | 19 | 14 |
| 24" | 24 | 19 |
| 30" | 34 | 24 |
On a PB glass pan burner, 4 inch spheres are an optional top layer over the glass: 14 for a 16 inch burner, 20 for 18 inch, 21 for 20 inch, 24 for 24 inch, 26 for 30 inch, 28 for 36 inch and 30 for 42 inch.
Questions people ask
Can I build a full set from 4-packs?
You can, but the complete sets cost less and arrive with the right count. 4-packs are meant for replacements and accents.
Will they turn black?
Some soot is normal on a pan burner. Peterson says so in the P45 manual.
Can I use them in a vent-free fireplace?
No. These are for vented burners.
