Gas fireplace repair and service in Lake Mann Estates

A pilot starved by a dirty orifice

The pilot runs through a tiny opening called the orifice, or spud. It passes only a small flow of gas, so dust, cobwebs or corrosion can starve it, and the result is a pilot that is weak, lazy or will not light at all.

Several complaints trace back here. A pilot too small to reach the thermopile, an electronic pilot that sparks but will not catch, or a flame rod that never sees enough flame can all start with a partly blocked orifice. One electronic ignition chart asks whether the pilot orifices are blocked, and one owner's manual has the technician clean or replace the orifice spud as needed.

We clean or replace it as the manual for that model describes, keep the pilot air opening clear and recheck the flame pattern afterward. A corroded spud becomes its own estimate line.

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.

No extra decor, media or accessories in the firebox

It is tempting to dress up a gas fireplace with extra stones, glass pieces or ornaments. One installation manual allows only accessories its maker approves, warning that unapproved components could make the fireplace overheat and that non-listed accessories void the warranty.

One direct vent manual warns that lava rock or ember chunks scattered on top of the burner may cause sooting, glass breakage and a fire hazard. Anything added can also cover ports or sit in the path the pilot flame uses to light the burner.

We take out anything that is not part of the maker's set and explain why, and approved media or log options for your model can be priced on the estimate. Items like these come out.

• Decorative stones or glass not supplied for the model
• Extra ember chunks on top of the burner
• Ornaments or seasonal decor set on the logs

A gas fireplace burns gas and nothing else

The logs in a gas fireplace look real, and that tempts some owners to add something. Two vent manuals from one maker are firm. Do not use any solid fuel such as wood, coal, paper or cardboard, do not cook food or burn other objects, and use only the gas type shown on the rating plate. Heatilator adds that gasoline, lantern fuel, kerosene and charcoal lighter fluid must never go into the appliance.

The direct vent one of the pair also warns never to connect the fireplace to a private, non-utility gas well. The burner, logs and ports are built around one fuel, and anything else in the firebox is outside what the appliance is listed for.

When our technician finds paper, trash or other burned material in a firebox, it is removed as one maker's yearly task list directs for foreign objects, and the logs, ember material and burner ports are checked for anything it left behind. What that finding needs, if anything, goes on the estimate.
