Instant Warmth for Lassen County's High-Desert Winters.
Reliable, on-demand heat for Susanville, Herlong, Westwood, and the ranch country in between—natural gas in town through Southwest Gas, propane everywhere else. Find the right unit and connect with a trusted local dealer.
Every Project Starts From One of These Five Situations
Clean heat that keeps up with plateau winters.
Lassen County sits on the high desert plateau of northeastern California, with Susanville at roughly 4,200 feet and outlying communities like Herlong, Westwood, and Standish spread across sagebrush flats and pine-covered foothills. With a long, demanding heating season and average winter lows around 22°F, this is Climate Zone 5B territory—comparable in severity to Bozeman, Montana rather than the California coast most people picture. Wood heat has deep roots here thanks to oak, madrone, and Douglas fir stands across the Lassen, Plumas, and Modoc National Forests, but a growing number of households are turning to gas for the rooms where they want heat without tending a fire.
Natural gas service through Southwest Gas covers much of Susanville and the immediate surrounding area; outside town—Herlong, Westwood, Janesville, and the county's ranch and rural residential parcels—propane is the standard fuel, delivered and stored in a tank on the property. Either way, a gas fireplace or insert gives you heat at the flip of a switch, which matters in a county where PG&E public safety power shutoffs during fire season aren't unusual. The right unit also sidesteps the smoke concerns that come with wood-burning during Lassen County's increasingly common wildfire smoke advisories.

Frequently Asked Questions
How much does a gas fireplace installation cost in Lassen County?
Most gas fireplace installations in Lassen County run somewhere between $4,000 and $10,000, with the spread driven mainly by whether you're on natural gas or propane, how much venting work is needed, and whether an existing masonry fireplace is being converted versus building out a new gas line from scratch. Homes in Susanville with existing natural gas service through Southwest Gas tend to land on the lower end. Rural properties in Herlong, Westwood, or outlying ranch country that need a new propane tank set and a longer gas line run typically land higher, and installers may add a modest travel charge for the distance. A local retailer will size the job accurately after an in-home look at your existing setup.
Can I convert my existing wood fireplace to gas?
Yes, and it's a common project for older Lassen County homes built around a traditional masonry fireplace. A gas insert slides into the existing firebox and vents through the same chimney using a stainless liner, which keeps the cost down compared to a ground-up install. For a home already burning oak or Douglas fir in an open hearth, converting to a sealed gas insert also means you're no longer dependent on a wood supply or subject to burn restrictions during wildfire smoke advisories. Whether you're on natural gas or propane affects the orifice and regulator setup, but doesn't change the basic scope of the conversion—your installer handles that part.
Do I need natural gas, or can I use propane?
Either works, and which one you use largely comes down to where you live. Susanville has natural gas service through Southwest Gas, so homes already running gas appliances there can typically add a fireplace with a straightforward tap into the existing line. Outside Susanville—Herlong, Westwood, Standish, and the county's rural residential and ranch parcels—propane is the standard, either from an existing tank or a new tank set by a local propane supplier. Nearly every gas fireplace on the market can be configured for either fuel; your installer sets the orifice and regulator to match.
Will my gas fireplace work during a power outage?
Most modern gas fireplaces will, which matters in a county where PG&E public safety power shutoffs are a real part of fire-season life. Units with IPI (intermittent pilot ignition) run on a battery backup that kicks in automatically when the power drops, so the fireplace lights on demand off the batteries until service is restored. Valor fireplaces take a slightly different approach—their pilot's thermocouple generates the small amount of electricity the ignition system needs, so there are no batteries to remember at all. For a rural county where outages can run longer than in town, that's worth asking about when you're comparing models with a local dealer.
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 choice for new construction or a remodel without an existing hearth. A gas insert drops into an existing masonry fireplace and uses the current chimney as its vent path, which makes it the natural fit for older Susanville and outlying homes with a traditional wood-burning hearth already in place. A gas stove is a freestanding unit that sits on the floor like a wood stove but runs on gas or propane—a good option if you want a stove-style look without an existing fireplace to convert. Most Lassen County homeowners upgrading an existing fireplace go with an insert; new rooms or new builds usually call for a built-in unit or freestanding stove.
Do I need a permit to install a gas fireplace in Lassen County?
Yes—a building permit and, for the gas line work, a permit tied to a licensed gas-fitter are both required through the Lassen County Building Department for new gas fireplace installations. Most established local installers handle the permitting as part of the job, so you're not left coordinating separate trades for the venting, the gas line, and the framing. If you're on propane and need a new tank set, your propane supplier typically handles that permitting separately.
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 the byproducts back outside through a sealed vent system. They're the cleanest, safest option and the one most local installers default to. Vent-free (or
How often should my gas fireplace be serviced?
An annual inspection is the standard recommendation for any gas appliance, including direct-vent fireplaces and inserts. A technician checks the burner, pilot assembly, venting, and gas connections, and cleans the glass and interior—a shorter visit than a wood chimney sweep, but just as important for safe operation. Local gas appliance service providers typically charge $150 to $250 for this annual visit, and it's worth scheduling before the start of each heating season rather than waiting until something acts up.
Gas vs. wood—which is right for my home?
Wood is deeply rooted in Lassen County, with oak, madrone, and Douglas fir available through inexpensive cutting permits ($5 to $20 per cord) on the Lassen, Plumas, and Modoc National Forests during the May-to-October season. It burns without electricity and costs less in fuel over a winter, but it also means dealing with ash, chimney maintenance, and—increasingly—periods where wildfire smoke advisories make any additional smoke unwelcome. Gas offers instant, consistent heat with no ash and no smoke of its own, and it's easy to run in a room you use daily without the upkeep. Many Lassen County homes end up with both: wood as a backup and a source of real heat during outages, gas for the everyday convenience in the main living space.
Is my gas fireplace wasting gas?
If it was installed more than 15 years ago, probably. Older gas fireplaces keep a standing pilot light burning all the time, and that little flame can cost a couple hundred dollars a year. Newer models use pilot-on-demand ignition—the pilot lights only when you use the fireplace and goes out when you turn it off.
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.
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.
