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.
Will it fit?
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.
Clearances
A vented gas log set borrows the fireplace's own clearances: the mantel, hearth and side-wall rules of the wood-burning fireplace it goes into stay exactly as they were built and inspected. What the log set adds is the room the burner and the flames need inside the firebox, below, and three rules: the damper fixed fully open with the clamp supplied, glass doors open or removed whenever the burner runs, and nothing stored or draped within 3 feet of the front of the fireplace.
Installation
A vented set goes into a wood-burning fireplace with a working chimney and a gas line, by a licensed gas installer, in about two hours.
- Gas: a dedicated 1/2-inch line to a shutoff at the fireplace; natural gas at 5 to 7 inches of water column, propane at 11 to 13. The connector runs through a plate in the firebox floor or wall.
- Damper: fixed fully open with the clamp in the box. This is the rule that makes a vented set safe; the fire's exhaust goes up the chimney like a wood fire's.
- Doors: open or removed whenever the burner runs.
- Burner: set on the grate in the center of the firebox, the logs placed by the diagram in the box, embers scattered on the burner, sand or vermiculite in the pan for natural gas, lava rock for propane.
- Controls: a match-light burner uses the fireplace's key valve; a safety-pilot burner has its own valve and knob; an electronic burner takes batteries in the control box or a 110-volt outlet inside the firebox for the plug-in version, and the remote pairs once.
- Codes: match-light burners are not allowed in some cities; the installer knows which. Most jurisdictions want the inspection.
How it performs
The Fyre Spheres 4-Pack set is a vented gas fire in a wood-burning fireplace: the burner runs under and through the logs, the flames are tall and yellow and move like a wood fire's, and the embers glow under them. The look depends on the burner as much as the logs. On the burner, the flame comes up through the log stack in more than one place, which is what makes people stop and look twice. It lights from a match, a knob or a remote, and the damper stays open, so the room does not get the heat a wood fire never gave it either.
Trade-offs to know
- Vented logs are decorative: the damper is open and most of the heat goes up the chimney. For heat, the vent-free version of this style is the one.
- The logs never burn away, but they char and darken where the flame touches; that is part of the look.
- Gas use is real: a 24-inch burner on high draws about what a large furnace does. Low is for long evenings.
Living with it
Brush the logs and the embers gently once a season and never wash them; replace the embers when they stop glowing. Keep the damper clamp on for good. Electronic controls take batteries yearly. Have the burner and pilot checked when the chimney is swept.

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.
What size gas line does it need?
A dedicated 1/2-inch line is typical for one burner; natural gas at 5 to 7 inches of water column at the burner, propane at 11 to 13. The installer sizes a long run.
Can I switch between logs styles later?
Yes. The logs sit on the burner; any Real Fyre log set for the same burner size can replace them. Keep the ember and pan materials.
Does the remote need electricity?
The battery-powered electronic burners run on batteries in the control and the remote; the 110-volt versions need an outlet inside the firebox. A safety-pilot burner with a remote is millivolt and needs no power at all.
How long do the logs last?
Peterson warrants the ceramic logs for as long as you own them. They char and darken, they do not burn away.
