What Johnstown is, fireplace-wise

Johnstown was incorporated in 1902 and became a home rule municipality on May 13, 1907. It sits at 4,994 feet, spans 13.84 square miles across the Weld and Larimer county line, and sits just west of where the Big Thompson and Little Thompson rivers meet, about 9 miles southeast of Loveland and 10 miles west-southwest of Greeley. The 2020 census counted 17,303 people, with estimates near 22,433 by 2025, and the town has pulled in Scheels, a Kroger fulfillment center, and a Buc-ee’s travel center along the I-25 corridor. All of that growth shows up behind the bottom louver.

• The 1902 core and the mid-century ring. Masonry fireplaces, many converted later to vented gas log sets on a manual valve and a standing pilot. Failures are thermocouples, clogged pilot hoods, corroded burner pans, and dampers. The gas logs page covers those.
• The 1990s and 2000s subdivisions. Factory direct-vent units with sealed glass, a thermopile, and a wall switch, now old enough to be on their second thermopile if they have had any service at all. This is where blower, gasket, and thermopile work comes from.
• Everything built in the last fifteen years. Electronic intermittent pilot ignition, a handheld remote, and a battery backup pack, with no standing pilot. Those fail as a click without flame, a dead receiver, or a flame sensing rod, and the clicks but will not light page is written for exactly this housing.

What fails here, and what it costs

Batteries first, always. In the new-build half of Johnstown the most common “dead fireplace” is a handset, a receiver, or a four-AA backup pack with nothing left in it. That answer is free. A genuine receiver or wall switch is $150 to $400.

Thermopiles in the older ring. A sensor reading 280 millivolts opens a cold valve and quits once the firebox is hot, so the fireplace runs ten minutes and shuts down. $200 to $400 installed, and the shuts off early page explains the heat-soaked reading that catches it.

October pilots. Six idle months put dust in a pilot hood, and the first cold night the pilot lights small and yellow. $200 to $400 for a thermocouple or thermopile, $300 to $600 for a full pilot assembly.

Altitude. At 4,994 feet Johnstown is within a few feet of Fort Collins, and the National Fuel Gas Code (NFPA 54 / ANSI Z223.1) calls for derating gas appliances installed above 2,000 feet by about 4 percent per 1,000 feet, with manufacturers’ natural-gas high-altitude kits typically starting above 4,500 feet. A unit that was set up for sea level soots its glass a week after cleaning. That check costs nothing and it is why the soot page leads with the orifice.

Blowers and gaskets. $250 to $600 and $200 to $600 respectively, both age items on 20-year-old direct-vent stock.

Permits, licensing, and gas

Johnstown issues its own permits through the town’s eTRAKiT portal and uses SafeBuilt for code questions, plan review, and inspections. A new or replacement fireplace is explicitly permitted work, as are plumbing, electrical, and new or replacement furnaces, water heaters, and air conditioning, and every contractor must hold a Town of Johnstown license before a permit is issued. The town enforces the 2024 International Building, Residential, Mechanical, Fuel and Gas, Plumbing, Fire, and Energy Conservation Codes along with the 2023 National Electrical Code. Colorado licenses the plumbers who run gas piping at the state level. A new insert or new gas line is permitted; a thermopile swap is not.

Gas territory here follows the county line more than the town line. Larimer County’s utility-provider list names Xcel Energy for natural gas, while Greeley to the east is Atmos Energy territory, so which company bills a Johnstown address depends on the address, and it prints on the statement. The parts and the pressures are the same either way. Acreage addresses off the mains run propane, which does change orifices and pressure.

Gas smell in Johnstown

Leave the house, leave the door open behind you, do not touch a light switch or a garage door opener, and call your gas utility’s emergency line or 911 from outside. Check the bill for whether that is Xcel or Atmos before you need it. Once the house is cleared, the safety inspection and leak check at $125 to $250 finds the fitting.
