Every Project Starts From One of These Five Situations
Instant heat for a valley that swings from windy winters to smoky summers.
Kittitas County sits in the rain shadow east of the Cascade crest, from Ellensburg at around 1,700 feet up to Cle Elum, Roslyn, and South Cle Elum climbing toward Snoqualmie Pass. At roughly 6,991 heating degree days and average winter lows near 22°F, the valley runs a heating season closer to Bozeman, Montana than to the wetter west side of the state—made worse by the persistent winds that make the Kittitas Valley one of the windiest corridors in Washington (and home to its wind farms). Cold snaps come fast and stay a while, and a lot of homes here run some kind of supplemental zone heat alongside a furnace or heat pump.
Natural gas service through Cascade Natural Gas reaches most of Ellensburg and its immediate surroundings, but once you're out toward Cle Elum, Roslyn, South Cle Elum, or the ranch and acreage properties scattered across the valley, propane is the standard fuel for a gas fireplace or insert. Either way, gas gives you heat on demand with no wood to split or stack, and during the summer wildfire smoke that regularly settles into the valley from surrounding forests, a sealed gas unit doesn't add another source of particulates to the air the way an open wood fire can. For homes that want reliable zone heat without the maintenance of a wood-burning appliance, gas is usually the fuel of choice.

Frequently Asked Questions
How much does a gas fireplace installation cost in Kittitas County?
A gas fireplace or insert installation in Kittitas County typically runs $4,500 to $11,000, depending on the unit, the venting run, and whether new gas line work is needed. A direct-vent insert dropped into an existing masonry fireplace with gas already nearby sits toward the low end. A new built-in unit in a remodel—with framing, a full vent run, and fresh gas piping—lands in the middle to upper range. If you're outside the Cascade Natural Gas service area around Ellensburg and need a new propane tank set, budget for that on top of the install. Local dealers will give you a firm number after seeing the space.
Can I convert my existing wood fireplace to gas?
Yes, and it's a common project in older Ellensburg and Cle Elum homes that still have a masonry wood fireplace. A gas insert typically slides into the existing firebox and vents through the same chimney using a stainless liner, running $4,500 to $9,500 depending on the insert and whether you're on natural gas or propane. Homes already on Cascade Natural Gas in Ellensburg tend to land on the lower end since there's no propane tank or long line run to add. The conversion keeps the look of the original fireplace while giving you real, controllable heat instead of an open draft.
Do I need natural gas, or can I use propane?
Either works, and which one you use largely comes down to where you live. Cascade Natural Gas serves Ellensburg and nearby areas, so if you already have gas appliances there, adding a fireplace is straightforward. Once you're out in Cle Elum, Roslyn, South Cle Elum, or on acreage elsewhere in the valley, propane is the standard choice, either from an existing tank or a new one set by a local propane supplier. Nearly every gas fireplace model on the market can be configured for either fuel—your installer sets the correct orifice and regulator for the one you have.
Will my gas fireplace work during a power outage?
Most will, which matters in a valley known for its wind. Units with intermittent pilot ignition (IPI) run on a small battery backup that kicks in automatically when the power drops, so the fireplace still lights on demand. Just remember to swap the batteries occasionally—they're easy to forget until you need them. Valor fireplaces take a different approach: the pilot's thermocouple generates the small amount of electricity the unit needs, so there's no battery to maintain at all. For Kittitas County homes that lose power during winter windstorms along the I-90 corridor, that kind of self-powered ignition is worth asking your local dealer about.
What's the difference between a gas fireplace, gas insert, and gas stove?
A gas fireplace is a fully built-in unit framed into a wall—the right call for new construction or a remodel without an existing fireplace. A gas insert fits into an existing masonry firebox and uses the chimney you already have, which is the more common route for older homes in Ellensburg and the Cle Elum/Roslyn area. A gas stove is a freestanding cabinet-style unit, similar in footprint to a wood stove, that can go almost anywhere with the right clearances and venting. Most Kittitas County homeowners upgrading an old wood fireplace end up with an insert; new builds usually go with a built-in unit.
Do I need a permit to install a gas fireplace in Kittitas County?
Yes. New gas fireplace installations need both a building permit and a gas line permit, typically handled through Kittitas County Community Development Services for unincorporated areas or the applicable city building department if you're inside Ellensburg or Cle Elum city limits. Gas line work has to be done by a licensed gas-fitter, which is one of the reasons it's worth working with an established local hearth dealer—they coordinate the gas line, venting, and inspections as one job instead of you juggling separate trades.
What's the difference between vented and vent-free gas fireplaces?
Vented gas fireplaces—direct-vent or B-vent—pull combustion air from outside and exhaust it back outside through a sealed flue. Vent-free units burn without any outside venting, releasing some water vapor and combustion byproducts into the room. Vent-free models are legal in Washington with room-size and ventilation restrictions, but given how often summer wildfire smoke already affects indoor air quality in the Kittitas Valley, most local dealers steer homeowners toward sealed direct-vent units instead—they heat well without adding anything to the air you're breathing indoors.
How often should my gas fireplace be serviced?
Plan on an annual inspection, ideally before the valley's cold snaps set in each fall. A technician checks the burner, pilot assembly, gas connections, and venting, and cleans the glass and interior. It's a lighter service than sweeping a wood chimney but still important—a dirty or misaligned pilot is one of the more common reasons a gas fireplace stops lighting reliably in cold weather. Most local service providers charge in the neighborhood of $150 to $250 for the visit.
Gas vs. wood—which is right for my home?
Wood is still a fixture in Kittitas County, with ponderosa pine, lodgepole pine, and Douglas fir cut locally under permits through the Okanogan-Wenatchee National Forest for $5 to $20 per cord during the May-to-October season. It's the cheaper fuel and it keeps working when the power's out. Gas trades that for push-button convenience, steady heat with no ash or smoke, and—importantly during summer wildfire smoke episodes that regularly settle into the valley—no additional particulates added to your air. For a primary living space or a home where convenience matters more than the ritual of tending a fire, gas is usually the better fit; wood still makes sense as backup heat or in a cabin setting.
Why is my open fireplace making my house colder?
Open fireplaces suck—literally. As the fire burns, it consumes air your furnace already paid to heat and pulls it out through the chimney, so the house is actually colder after the fire goes out than before you lit it. An insert fixes this: it seals the chimney, puts fixed glass across the front, and turns that hole in your house into a real heat source.
Why is a fireplace insert so efficient?
An insert does two things: it seals the chimney completely, so you stop losing air you already paid to heat, and it radiates warmth into the room through the firebox and glass. Most add a heat-exchange fan that pulls cool room air underneath, wraps it around the hot firebox, and pushes it back out warm. Your home is more efficient before you've even lit the first fire.
What is an in-home preview and do I need one?
It's a visit where a hearth professional measures your space, confirms the model you picked actually works in your home, and walks the specs—framing, gas line, venting, finish work—before anything is ordered. Some details you just can't know until you see the house. Never make a down payment without one; it's the single most-skipped step that burns buyers.
Can I install a fireplace myself?
If you're putting a fire in your house on purpose, it's best to work with an expert. Unless you're genuinely experienced in framing, gas line, vent pipe, and the national code on clearances to combustibles, have a professional do it—and ideally the same company that sells you the fireplace, so warranty, service, and liability all live under one roof.
