Superior Crescent Hill HD: the same two row vent-free fire with sharper, more detailed logs
The Superior Crescent Hill HD is a vent-free gas log set that fits in the fireplace you already have. HD stands for high definition. The concrete logs are molded with deeper bark and cleaner split ends than the standard Crescent Hill set, so they look more like real firewood up close. Two rows of yellow flames dance between the logs. The logs come in lengths of 18 or 24 inches. Pick the size on the page.
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 36,000 BTU. It keeps heating when the power is out because the burner needs no electricity. The burner is not included. On the page you pick the log size, the fuel, and the burner. Order it for natural gas or propane. The manual burner has a knob that turns the flame up and down. The millivolt burner is remote ready, so 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 Crescent Hill HD ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.

FAQ
What is the difference between Crescent Hill HD and the standard Crescent Hill?
Same Double-Flame burner, sizes and output; HD stands for high-definition logs with sharper bark and split-wood detail, sold at a small premium over the standard Crescent Hill concrete logs. Both are 18 or 24 in sets that run vent-free with the damper closed at 99 percent efficiency, or vented with the optional damper clamp.
Is a burner included?
The burner is a required choice on the Burner selector after you pick size and fuel: Manual, with a variable high-low flame knob, or Millivolt, which is remote-ready for the on/off remote, thermostatic remote, touch screen remote, wall thermostat or wall switch on the Accessories row. Neither needs household electricity.
How much heat and what fireplace size?
36,000 down to 19,000 BTU for both sizes per the Specifications tab, with a minimum fireplace width of 24 in for the 18 in set and 28 in for the 24 in set, 17 in of height and 13-1/2 in of depth. Vent-free, almost all of that heats the room, so use the burner manual’s ventilation-air calculation to size it.
Can I run it with the damper closed?
Yes; that is the vent-free mode the Double-Flame series is designed for, with no heat lost up the chimney. It is also listed for vented use in a working fireplace with the damper clamp from the Accessories row holding the damper open. Local codes decide whether vent-free operation is allowed in your area and room.
Natural gas or propane?
Both, chosen on the Fuel Type selector, which switches the Burner row to the natural gas or propane version at the same price. Browse more ventless gas logs if you want a taller flame style such as the Triple-Flame or Mega-Flame sets.
Does it heat during a power outage?
Yes. Both the manual and millivolt burners use a standing pilot and need no electricity, which the description highlights: vent-free heating logs keep you warm when the power is out. Any remote you add to the millivolt version runs on its own batteries.
