Superior Multi-Sided: a complete vent-free gas log heater that looks right from every side
The Superior Multi-Sided is a vent-free gas log set made for a fireplace that is open on more than one side. A see through, peninsula, corner, or island fireplace exposes the back of a standard log set. This one has five ceramic fiber logs arranged so the fire looks finished from any angle. Two rows of tall yellow flames rise through the stack. It is 27 inches long.
Vent-free means you can run it with the damper closed, so nearly all the heat stays in the room. It puts out up to 39,000 BTU. Unlike most Superior log sets, this one comes with its burner. The burner is millivolt, so it needs no electricity and keeps heating when the power is out. Order it for natural gas or propane. It is remote ready, and on the page you can add an on and off remote, a thermostat remote, or a wall switch. Check your local code first, since some areas restrict vent-free heaters.

The Superior Multi-Sided ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
FAQ
What fireplaces is the Multi-Sided log set for?
See-through, peninsula, corner and island fireplaces with more than one open side, where a normal front-view set would show a bare back. Its five-piece log arrangement and two rows of tall yellow flames from the dual burner look right from any angle. It is a single 27 in size for a fireplace at least 32 in wide, 17 in high and 19 in deep.
Is the burner included?
Yes. Unlike Superior’s front-view log sets, this listing is a complete vent-free gas log heater with the remote-ready millivolt burner and ceramic fiber logs together, which is why the only selectors are Fuel and Accessories. It runs vent-free with the damper closed at 99 percent efficiency or vented with the damper clamp.
How much heat does it produce?
39,000 down to 20,000 BTU per the Specifications tab, adjustable across that range at the valve or with an optional thermostatic remote. As a vent-free heater it warms both rooms of a see-through fireplace, so run the burner manual’s ventilation-air calculation for the combined space and check local vent-free rules.
Natural gas or propane?
Both: the Fuel selector picks the FVFM27NR natural gas or FVFM27PR propane version at the same price, and because the burner is built into this listing the whole heater ships set for your fuel. There is no conversion kit on the page, so choose carefully. Compare fireplaces that suit it in our multi-sided fireplaces category.
What controls can I add?
The millivolt burner is remote-ready, so the Accessories row offers an on/off remote with wall plate, a thermostatic on/off remote, a touch screen remote, a wall-mount thermostat and an on/off wall switch, plus volcanic stone, a floor media kit, the damper clamp for vented use, a gas appliance installation kit and a black fireplace hood.
Does it work in a power outage?
Yes. The millivolt burner’s standing pilot needs no household electricity, so the set lights and heats through an outage; remotes use their own batteries. Vent-free operation means none of that heat leaves up a chimney.
