Propane and natural gas fireplace repair in McDonald

Repairs that keep the appliance within its listing

Florida's code for fuel gas appliances says defective parts are replaced or repaired in a way that preserves the original approval or listing. A gas fireplace was tested as a system, with its own valve, pilot, burner, logs and glass. A part from outside that system can change how it behaves.

Makers say the same thing in plain words. Installation instructions from one insert maker warn against installing damaged, incomplete or substitute components, and say a component part it has not approved voids the warranty. Even wiring has a rule there, since damaged wire is replaced with high temperature rated wire.

Universal parts that the manual does not allow stay off our list. What we quote is the part the maker specifies for your model, named on the estimate by the maker's own description, and checked against these points.

• A part named in the maker's service parts list
• An accessory the maker has approved for the model
• Wire with the temperature rating the manual calls for

The air shutter and a sooty flame

The air shutter lets a measured amount of air mix with the gas before it burns. According to one insert installation manual, the shutter is set at the factory for the minimum vertical vent run, may be adjusted for longer runs and should be opened to give more air if sooting occurs.

That manual gives a table of settings by model and gas, and the owner manual's service list asks the technician to confirm the setting and check that the shutter is clear of dust and debris. A shutter that has been moved or clogged changes the flame even when every other part is sound.

It is a technician setting, made at installation and checked on service, not an owner adjustment. We compare the shutter on your McDonald fireplace with the manual's setting for its vent layout, correct it where the manual allows and list any soot damage it has already caused on the estimate.

How the flame should look once warm

A gas flame changes as the fireplace warms. One owner's manual says blue flames at start-up are normal and begin to yellow as the fireplace keeps running. A direct vent manual from another maker describes the warmed-up flame on its models as yellow and slightly taller than the rear log, after about 15 to 30 minutes at full rate.

Those descriptions are model-specific, and the same manual notes that the type of installation, the vent layout and wind can make the pattern vary. So a flame that looks different from another fireplace is not a fault by itself. A flame that stays blue and short, one that leaves dark marks on the logs, or one that has changed from how it used to look is worth a check.

On a visit to your McDonald home, the flame is watched from a cold start until fully warm and compared with what the manual for that model describes. Any gap between the two is traced to its cause and written into the estimate.

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.
