Propane and natural gas fireplace repair in Lake Fredrica

Decorative fireplace or fireplace heater

The fuel gas volume of the Florida Building Code sorts gas fireplaces by the standard they are listed to. That listing changes what a technician should expect from the unit in front of them.

The difference shows in the manuals. One natural vent series is tested to Z21.50, and its manual calls it a decorative appliance that is not intended for use with a thermostat. A direct vent series from the same maker is tested to Z21.88 as a fireplace heater, so two units that look alike from across the room can carry different controls and settings.

Reading the standard off the plate comes before judging how your fireplace should behave, and the estimate names it beside the model. The code names these listing standards.

• ANSI Z21.50 for vented gas fireplaces, the decorative kind
• ANSI Z21.88 for vented gas fireplace heaters
• ANSI Z21.60 for decorative log sets in solid fuel fireplaces

Intermittent pilot ignition and its control module

On an intermittent pilot ignition system, usually shortened to IPI, a control module runs the start. It sparks the pilot, senses that the pilot flame is really there and only then opens gas to the main burner. When the fireplace turns off, the pilot goes out as well, which Heat & Glo's owner manual describes as normal for its IPI units.

That module needs power. The installation manual for those units calls the power cord connection required for the IntelliFire Touch ignition to work, with a battery backup for outages. The same module can lock itself out after a fault and flash an error code until it is reset.

Power, spark, flame sensing and the signal to the valve are separate steps, and our technician checks each one on a visit in Lake Fredrica. The estimate names the step that failed rather than listing a new module by default.

A gas fireplace that has been under water

Water and gas controls do not mix. The manuals we have read agree on this. An appliance with any part that has been under water stays off until a qualified service technician has inspected it and replaced each part of the control system and each gas control that got wet. That holds even when the unit looks clean and dry afterward.

One natural vent manual goes further and calls for arranging replacement of the unit. Another simply tells owners to keep the appliance dry, because water may damage controls. The state fuel gas code also sets rules for where appliances sit in flood hazard areas, which matters if the fireplace is replaced.

We read the model from the rating plate, find that model's instructions and list every control part the maker calls for, or the replacement option where the manual requires it. The fireplace is not lit until that work is done.

Freestanding gas stoves and fireplace heaters

Not every gas appliance with a flame behind glass is a built-in fireplace. Freestanding gas stoves, inserts and wall units are often heaters as much as decorative fireplaces, and the state's fuel gas code treats them that way. Vented gas fireplace heaters, vented room heaters and wall furnaces each have their own listing standard in that code, and each is installed per the manufacturer's instructions.

The listing shows on the rating plate. Heat & Glo's Supreme inserts, for example, are listed as vented gas fireplace heaters rather than decorative fireplaces. Service follows the same order as on any fireplace, the plate first, then the maker's manual and the parts it names.

Units without a vent are different appliances under different rules, and they go to our ventless gas fireplace service. For vented stoves and heaters in your Lake Fredrica home, our technician handles the pilot, burner, controls and fan as on a fireplace, and the estimate names the listing with the model.
