Gas Logs, Remotes, and Blowers in Fort Collins

Gas logs, remotes, and blowers in Fort Collins price like this: a remote receiver or wall switch $150 to $400 installed, a blower kit or replacement $250 to $600, a replacement log set $300 to $1,200, and a new gas log set installed in an existing masonry fireplace $600 to $1,800 plus the gas line. These are the parts that make a fireplace convenient and warm rather than merely lit, and they fail in ways that get misdiagnosed as bigger problems.

As on every page: if you smell gas, leave the house and call Xcel Energy or 911 from outside.

Remotes and wall switches

Every gas fireplace turns on through a low-voltage circuit: a wall switch, a wall thermostat, or a remote receiver wired to the valve. On a standing-pilot unit that circuit is powered by the thermopile’s 300 to 750 millivolts and nothing else, which is why a corroded switch contact or a thin wire can stop a perfectly good fireplace. On an electronic unit the receiver talks to the ignition module.

The systems we see most: Skytech, Proflame (the SIT system on a lot of Heat & Glo, Napoleon, and Regency units), and Acumen. Each has a handheld and a receiver box, usually behind the bottom louver next to the valve.

Before you call, in this order:

1. Fresh batteries in the handheld.
2. Fresh batteries in the receiver box. They die every one to two years and nobody remembers they exist.
3. On the receiver, the slide switch: Remote, Off, or On. Set to On, the fireplace should light without the handheld. If it does, the problem is the remote or its pairing, not the fireplace.
4. Re-pair the handheld to the receiver per the manual (usually a learn button on the receiver).

If it still does nothing, the visit runs through the thermopile reading first, because a receiver cannot open a valve on 200 millivolts, then the switch and wiring, then the receiver. A remote quoted without a thermopile reading is a guess. The pilot and ignition page explains the reading.

Upgrading from a wall switch to a thermostatic remote is the same $150 to $400 range and is the most-appreciated small upgrade on a 1990s direct-vent unit.

Blowers and fan kits

A blower does not affect combustion. It pulls room air through the bottom louver, across the hot steel of the firebox, and out the top, and on a direct-vent unit it is the difference between a pretty fire and a warm room. Most factory fireplaces from the city’s late-20th-century southward expansion were pre-wired for one, with a junction box under the unit; some got the kit at construction and some did not.

Failures: a squeal or rattle (bearings), no fan (dead motor, failed speed control, or a thermostatic snap switch that no longer closes), fan runs but weakly (cage packed with lint, which is also why the motor overheated). Cleaning the cage is part of annual service; a new blower or a first-time kit is $250 to $600 installed, including the variable-speed control.

Blowers need 120 volts, so a unit with no outlet underneath needs an electrician for the outlet, which is a separate state-licensed trade in Colorado.

Log sets: replacement, vented, and vent-free

Replacing logs in an existing unit ($300 to $1,200)

Ceramic fiber and refractory logs crack, chip, and shed over 15 to 20 years, and once a log breaks it tends to sit wrong on the burner. Replacement sets are brand and model specific because the log geometry is designed around the burner ports and the pilot; a generic set that “looks close” is how you get soot and a fouled thermopile. The rating plate photo tells us which set you need. Embers and glowing-ember material get refreshed at the same time.

New vented gas logs in a masonry fireplace ($600 to $1,800 plus gas line)

The Old Town streets around the 1978 National Register district, and the 1960s and 1970s subdivisions that followed, are full of masonry wood-burning fireplaces that owners want to keep using without hauling wood. A vented log set is a burner pan, a grate, and a ceramic log set installed in the open firebox, with the damper clamped permanently partly open so the exhaust goes up the chimney. Realistic flame, wood-fire look, modest heat, because most of the heat goes up the flue with the exhaust.

The gas line to the firebox is a separate item: gas piping in Colorado is plumbing under the State Plumbing Board, whose rules require a permit and inspection for all fuel gas piping work, with a rough inspection under air test. Larimer County lists gas log inserts and gas lines and gas appliances among its Miscellaneous Permits; the City of Fort Collins lists gas fireplaces as permit work. The chimney has to be sound and open, so a chimney that has not been used in years gets looked at first.

Vent-free (unvented) logs

An oxygen depletion sensor pilot shuts the unit down if room oxygen drops. Cleaner burn, all the heat stays in the room, no chimney needed. The trade-offs are real: water vapor and combustion products go into the living space, there is a faint odor, and a tight modern house in Timnath or south Fort Collins can show condensation on windows. We install them where they fit and steer people away from them where they do not, particularly households with asthma or infants. Local code and HOA rules vary; we check before quoting.

Altitude on log sets

Every log set has an orifice, and at 4,997 feet in Fort Collins the National Fuel Gas Code’s derate of about 4 percent per 1,000 feet above 2,000 feet applies to it as much as to a furnace. Vented log sets are the units we most often find running the sea-level orifice, because they get installed by whoever ran the gas line. Yellow, lazy flame and soot on the logs is the tell. In Estes Park at 7,743 feet, and on the propane cabins there, the orifice and regulator setting are different again.
