When the pilot burns but the burner stays off

A steady pilot with no main flame means the pilot safety is holding and the fault sits further along, between the call for heat and the burner valve. On millivolt units, one maker's charts work through it in a set order.

The thermopile reading settles the last question. Low output means the pilot assembly, while adequate output with the switch on and still no burner means the valve. A pilot flame that sits too far from the thermopile is adjusted before either part is condemned.

Each result goes on the estimate, so a valve is not quoted when a loose switch wire was the real cause. Our technician runs these checks in order at your Spring Isle home.

• The wall switch or remote and its connections
• The wiring between the switch and the valve
• How far the pilot flame reaches onto the thermopile
• The thermopile's output, read at the valve terminals

A pilot that stays lit or goes out when off

Owners often ask whether the pilot should burn all the time, and owner's manuals answer it in their question tables. It depends on the system and how it is set, so neither a steady pilot nor a dark one is a fault by itself.

Some electronic systems keep the pilot lit on purpose. One insert's remote has a pilot-on setting, labeled cold climate, for that. A command system from another maker can be configured for a standing or an intermittent pilot, and in standing mode the pilot stays lit after the burner shuts off.

A standing pilot on a millivolt valve is meant to be present whenever the fireplace is in operation. Our technician confirms the design and the mode your fireplace is set to before calling anything a defect, and the estimate names that setup so the next service starts from the same facts.

Only the fan kit the maker approves

Adding a fan to a fireplace that never had one sounds like a simple upgrade. The manuals warn against doing it casually. Among its warnings, a sealed-unit manual says not to use a blower insert, heat exchanger insert or any other accessory not approved for use with that fireplace, and its natural vent manual carries the same warning.

An insert maker says to use only its approved optional accessories and warns that non-listed accessories could create a safety hazard. Florida's fuel gas code expects an appliance to be listed and labeled for the application in which it is used, and a fan the listing never covered sits outside that.

The parts list for your model settles it. Where the maker offers a fan kit, that kit and its wiring go on the estimate with the model it belongs to. Where it does not, you hear that plainly, and no universal fan is fitted in its place.

Shutting the fireplace down for a long break

A fireplace that will sit unused for months, or while the house is empty, is best left so it cannot start by accident. The upkeep section of one manual gives that reason, to prevent unintended operation during summer months, vacations or trips, and its steps are about the controls.

A standing pilot is a separate choice. It can stay lit or be shut off for the break, and the manual for that model describes how it is shut off. On that maker's module, the off position means the fireplace ignores the wall switch and both remotes, which is why that switch matters more than a remote's own off button.

A maintenance visit just before a long absence is a good moment for this. The controls can be left in the state your model's manual describes, with a note of what to switch back on later.

• Wall controls switched off
• The module's selector switch set to off
• Batteries out of remotes and the backup pack
