Every Project Starts From One of These Five Situations
Steady warmth without splitting a single log.
LaSalle County sits along the Illinois River in north-central Illinois, home to roughly 85,401 people spread across Ottawa, Peru, LaSalle, Streator, Mendota, Oglesby, and a wide ring of farmland in between. Winters here are genuinely cold—climate zone 5A, an average winter low near 14°F, and a heating season on par with what a Madison, Wisconsin household deals with most winters. The county's oak, hickory, walnut, and maple river-bottom timber has kept wood stoves relevant for generations, but a growing share of homeowners—especially in the older brick and frame housing stock around Ottawa and Peru's historic districts—are turning to gas for the convenience of heat at the flip of a switch.
Nicor Gas provides natural gas service through most of the incorporated communities along the Illinois River corridor, including Ottawa, Peru, LaSalle, Streator, Mendota, and Oglesby. Once you're out past city limits, in the unincorporated townships and farmsteads that make up much of the county, propane from regional suppliers is the standard fuel. Either way, a properly installed gas fireplace or insert gives you zone heat for a drafty living room, a backup source of warmth if the furnace goes down during a January cold snap, and none of the ash, creosote, or wood-splitting that comes with a cordwood stove.

Frequently Asked Questions
How much does a gas fireplace installation cost in LaSalle County?
A gas fireplace or insert installation in LaSalle County typically runs $4,000 to $10,500, depending on the unit, the venting path, and whether new gas line work is needed. A direct-vent insert going into an existing masonry fireplace with gas already run to the room sits toward the lower end. New construction or a fireplace added where no gas line currently exists—common in some of the older farmhouses outside Ottawa and Streator—pushes toward the higher end once trenching or a propane tank setup is factored in. A local dealer will give you a firm number after seeing the space.
Can I convert my existing wood fireplace to gas?
Yes, and it's one of the more common projects for LaSalle County's older housing stock—plenty of homes in Ottawa, Peru, and Streator still have the original masonry fireplace from decades past. A gas insert slides into that existing firebox, uses a stainless liner run up your current chimney for venting, and typically runs $4,500 to $9,000 installed. If you're on Nicor Gas already, and the appliance is on the same side of the house as an existing gas line, costs land on the lower end. Homes relying on propane sometimes need a bit more line work, which adds to the total.
Do I need natural gas to install a gas fireplace, or can I use propane?
Either works. If you're inside Ottawa, Peru, LaSalle, Streator, Mendota, or Oglesby, you're likely within Nicor Gas's natural gas territory, and if your home already has gas appliances, adding a fireplace is usually a straightforward tie-in. Outside those city limits, in the unincorporated parts of the county, propane is the standard fuel, supplied by regional propane companies that serve the area's farms and rural subdivisions. Most gas fireplace models can be set up for either fuel—your installer configures the correct orifice and regulator for whichever one you have.
Will my gas fireplace work during a power outage?
Most modern gas fireplaces will. 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 just like normal. Valor takes a different approach: their units generate their own electricity off the pilot's thermocouple, so there's no battery to remember at all. That distinction matters in LaSalle County, where ice storms and high winds off the open farmland can knock out power for a day or more in a bad winter. Ask your local dealer which ignition system is on any unit you're considering.
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 major remodel. A gas insert is built to drop into an existing masonry fireplace, which is common in LaSalle County's older Ottawa, Peru, and Streator neighborhoods, and it uses your current chimney as the vent path. A gas stove is a freestanding unit that sits on the floor like a wood stove but burns gas, and works well in rooms without an existing fireplace or chimney. For most homeowners here with a fireplace already in place, an insert is the straightforward upgrade.
Do I need a permit to install a gas fireplace in LaSalle County?
Yes. If your home is within Ottawa, Peru, LaSalle, Streator, Mendota, or Oglesby city limits, you'll pull a building permit and gas permit through that city's building department. If you're in unincorporated LaSalle County, permitting runs through the LaSalle County Building & Zoning Department. Gas line work also needs to be done by a licensed gas-fitter—most established hearth dealers coordinate the permit, the gas line, and the final inspection as one package, so you're not chasing 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 the byproducts back outside through a sealed system. Vent-free units burn gas directly into the room without any outside venting, and while Illinois permits them with room-sizing and oxygen-sensor requirements, they release some water vapor and combustion byproducts into your living space. Given LaSalle County's real cold—winter lows averaging 14°F and a heating season on par with what a Madison, Wisconsin household deals with most winters—a direct-vent unit is the safer, more universally recommended choice, and it's what most local dealers will steer you toward for a primary living space.
How often should my gas fireplace be serviced?
Plan on an annual inspection, ideally before the heating season ramps up in the fall. A technician checks the burner, pilot assembly, venting, and any gas connections, and cleans the glass and interior. It's a quicker job than a wood chimney sweep, but skipping it is how small pilot or ignition issues turn into a fireplace that won't light on the coldest night of the year. Most LaSalle County gas appliance service providers charge in the range of $150 to $250 for the visit.
Gas vs. wood—which is right for my home?
LaSalle County has no air quality restrictions on wood burning, and the county's oak, hickory, walnut, and maple mean firewood is genuinely abundant if you want it—wood also keeps working during a power outage, which gas units without battery backup won't. Gas wins on convenience: no splitting, hauling, or ash cleanup, instant on-off operation, and more even heat output for daily use. A lot of LaSalle County homeowners end up with both—gas in the main living space for everyday warmth, and a wood stove in a workshop, basement, or secondary space for backup heat and the lower running cost of burning your own timber.
What's the difference between an insert and a zero-clearance fireplace?
An insert is a fireplace that slides into a pre-existing wood-burning fireplace—if you don't have one, there's nothing to insert it into. A zero-clearance fireplace is built into a framed wall, which makes it the answer for remodels and new construction. Simple test: existing masonry fireplace means insert; blank or framed wall means zero-clearance.
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.
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.
Should the dealer who sells my fireplace also install it?
Ideally, yes. A fireplace project involves vent pipe, gas line, electrical, and often tile or stone. Hire three or four separate trades and you own the liability and the game of telephone between them. One company selling and installing means one accountable party, start to finish—ask about factory training, on-time completion records, and what happens if an inspection fails.
