Vent-free repair notes from our North Orange technicians
Each topic below can show up on an estimate in North Orange, so here is what it means.
Why the Florida code requires an ODS on vent-free units
Section 621.6 of the Florida Building Code, Fuel Gas, requires every unvented room heater to carry an oxygen-depletion safety shutoff. It has to shut off the gas to the main burner and the pilot when the room's oxygen drops to the level the manufacturer specifies, and the code sets a floor below which that level may not go.
So the ODS is never treated as optional hardware. When one fails, our specialists replace it with the assembly listed for your model and gas type, then test the shutdown before the fireplace goes back into service.
Reading the pilot flame against the thermocouple
On many vent-free units the pilot flame has to wrap the thermocouple to hold the gas valve open. One manual prints the correct pattern beside a faulty one in which the flame misses the thermocouple. The thermocouple cools, and the heater shuts down.
A pilot knocked out of position, a partly blocked orifice or low gas pressure can each move that flame. Our specialists identify which one is at work before quoting a part, so you never pay for a thermocouple the fireplace did not need.
Loose logs and worn pin holes
Many vent-free logs lock onto pins on the grate or burner. One manufacturer says the logs must fit firmly on the burner when positioned as shown, and that malformed logs or logs with sloppy pin holes must be replaced.
A log that rocks on its pins drifts into the flame over time. We check each fit by hand and quote replacement logs by part number from your model's parts list, so the new piece seats on the pins it was made for.
Orifice alignment in the burner venturi
On some vent-free burners, primary air enters through a venturi tube at the back. One manufacturer notes that airflow drops when lint or dirt builds up around the venturi, or when the gas orifice sits off center or out of line with the venturi inlet.
The maker describes a correction for a misaligned orifice. That adjustment belongs in trained hands, and our specialists make it only where your manual describes it, then confirm the flame afterward.
Shut off and cooled before any service
Before cleaning or service, a vent-free unit has to be turned off, pilot included, and allowed to cool. One manual says to wait at least 30 minutes before inspecting the burner and pilot.
So we ask owners to leave the fireplace off before a scheduled visit. It saves time on the day, the work starts sooner, and the inspection is still free.

Questions North Orange owners ask about vent-free logs
Plain answers first, and a free visit in North Orange whenever you want the fireplace checked.
Can vent-free logs go in a prefab fireplace?
Only when that factory-built fireplace was tested, listed and labeled for unvented use under UL 127, as section 621.7 of the Florida fuel gas code requires. One log set manual adds that it must not go in a factory-built unit whose instructions say it was not tested with unvented logs.
Can I add embers or lava rock to vent-free logs?
Only as your manual allows. One maker limits rock wool embers to a single layer on the front of the burner and keeps lava rock on the fireplace floor. Other manuals ban added logs, pine cones, vermiculite and rock wool because they cause sooting.
