Keeping a vent-free fireplace within its listing
Pilot that dies when the gas knob is released
On a millivolt control, the pilot is held in by hand until the sensing tip warms. If the pilot dies the moment the knob is released, the thermocouple is not holding the valve open. The cause can be a dirty pilot, a weak flame, a loose connection at the valve or a worn part.
We check them in that order, because the simpler causes come first. Please do not hold the knob in longer than the manual says, or relight again and again. Leave the unit off and describe what happened when you phone us.
Two kinds of ventless shutdown
The troubleshooting charts in vent-free manuals split shutdowns into two groups. In one, the main burner stops while the pilot stays lit. In the other, the pilot goes out too and the unit closes completely. Each group has its own list of causes.
Tell us which one you saw, if you noticed. A burner that drops back to pilot may be a thermostat, a control or a pressure question. A full shutdown more often involves the sensor, its air supply or the room. Knowing which path to follow keeps the visit focused.
The host fireplace must allow vent-free logs
A vent-free log set may go only into a fireplace that allows it. For factory-built fireplaces, the residential volume of the Florida Building Code sets a clear rule. Unvented gas logs belong there only when the fireplace itself has been tested, listed and labeled for them. Some fireplace manuals say outright that the unit was not tested with unvented burners.
We read both labels, the log set's and the fireplace's, before servicing the logs. If the host does not allow them, we explain that plainly. Servicing a set in a fireplace that forbids it is not a repair we can offer.
Replacing a whole vent-free burner system
Sometimes the practical answer is a new burner system rather than another part. Discontinued pilots, a damaged valve without a listed replacement or a burner warped by heat can lead there. We explain why before suggesting it.
A replacement system must be listed for the host fireplace and sized for the room, the same as the original. The estimate names the model, what it includes and what happens to the old set. You approve it as its own item, separate from any service work.

Oxygen depletion sensor questions, answered
How is an ODS pilot cleaned during a service visit?
With the unit off and cool, the pilot area is brushed lightly while loose debris is vacuumed away, so nothing goes into the pilot opening. The air intakes are cleared, and the flame is compared with the manual's picture afterward.
Can a vent-free fireplace be used after it was under water?
Not until it has been inspected. The manuals say to replace any part of the control system and any gas control that has been under water. We identify those parts from the maker's list and price them before any work.
What happens during a free inspection of a ventless unit in Twin Lakes North?
We identify the model from its rating plate, look at the pilot, burner, logs and room, and explain what we found. You receive a written estimate with each item separate, and nothing is done until you approve it.
