Hargrove Radiant Heat 30" Cimarron Timber Vent Free Log Set
The Hargrove Radiant Heat 30" Cimarron Timbers set brings Hargrove's Radiant Heat Technology to a vent-free log set: textured timbers in warm brown tones over a large glowing ember bed, with up to 39,000 Btu/hr on natural gas warming the room as it burns.
Hargrove molds these logs with a process it says gives detail that was not possible with ceramic fiber logs before. This listing covers the 30" set, model RGCI30, in natural gas or propane with a millivolt, variable flame or electronic ignition valve. A 24" size is also available.
The Hargrove Cimarron Timbers 30": Radiant Heat You Can Feel Right Away
Hargrove built the Radiant Heat series so you feel the warmth as soon as the set lights, and the glowing ember bed keeps the fire looking alive between flames. The Cimarron Timbers gives you a classic wood fire in a fireplace you no longer want to feed with wood. See the rest of Hargrove's sets in our gas logs collection.
Hargrove's vent-free sets run as an unvented room heater in a masonry or manufactured wood-burning fireplace with the flue damper closed, or in a vent-free fireplace listed and approved with Hargrove products. Because the Cimarron Timbers is dual listed, it can also burn as a vented log set in a wood-burning fireplace with the chimney damper fully or partially open.
The 30" set needs an opening at least 17" high, 38" wide at the front, 26" wide at the back and 14-1/2" deep. Hargrove asks for 15" from the opening to a combustible side wall, 42" to a combustible ceiling and 6" to each side of a mantel. Run vent-free, the room has to be an unconfined space of at least 50 cubic feet for every 1,000 Btu/hr of gas appliances in it, so this set alone needs about 1,950 cubic feet on natural gas.
A qualified gas installer sets it up with a manual shutoff valve in the supply line, plus an external regulator on a propane tank. It is not for bedrooms, bathrooms or recreational vehicles, and glass fireplace doors have to be fully open whenever it runs. Before you buy, check that your local code allows unvented gas appliances; our direct vent vs. vent-free guide explains where they are restricted.

Choosing a Valve
-
Millivolt (2C): a standing pilot valve that is remote ready and ships with an on/off switch. It works with Hargrove's millivolt remotes, wall switch, wall thermostat and bark chip or pine cone switches.
-
Variable flame (1E): remote ready, with flame height you can raise and lower from Hargrove's variable flame remotes.
-
Electronic ignition (3E): comes with a variable remote that lights the pilot and burner and raises or lowers the flame. There is no standing pilot; it shuts off when the burner is turned off.

FAQs
Can I run the Cimarron Timbers with the chimney damper open?
Yes. The set is dual listed, so in a wood-burning fireplace it can run as a vented log set with the damper fully or partially open. Hargrove notes that mantel clearances do not apply when it is installed as a vented appliance in a fireplace that can burn wood. With the damper closed it runs vent-free.
How large does the room need to be?
For vent-free use the room must be an unconfined space: at least 50 cubic feet per 1,000 Btu/hr of all the gas appliances in it. At 39,000 Btu/hr on natural gas, this set alone needs about 1,950 cubic feet, and adjoining rooms joined by doorless passageways or ventilation grills count. Direct vent appliances are left out of the total.
Which remote do I need?
It depends on the valve: the millivolt (2C) set works with Hargrove's millivolt remotes and switches; the variable flame (1E) set takes the RC-S6V-MX, RC-S6V-MXT or RC-R300; the electronic ignition (3E) set already includes a variable remote. Our millivolt vs. electronic ignition guide covers how standing pilot and electronic ignition systems differ.
