Chimney Services in Vineland, NJ

Close to a third of Vineland's homes date from the 1960s and 1970s, and three in four households already heat with gas. If you own a fireplace from that era and are thinking about a gas insert, the answer starts with measuring what you already have.

What the numbers suggest for chimneys in Vineland

Census estimates place about 31% of Vineland's 22,768 housing units in the 1960s and 1970s, another 20% between 1940 and 1959 and 14% before 1940. Houses from those decades commonly have masonry chimneys, and a single chimney often holds two passages, the fireplace's and the heating system's. Our guide to chimneys with more than one flue explains how to tell them apart from the roof and from the basement.

About 75% of occupied homes heat with utility gas, 11% with electricity, 9% with fuel oil and 3% with propane. Gas furnaces and water heaters venting into masonry send a lot of water vapor up the flue, which is the subject of our guide to chimney condensation. The 9% on oil points to flues that gather soot and need cleaning on a schedule.

Roughly 68% of units are detached houses and 13% are in buildings of five or more units. These are citywide estimates. They cannot tell you how a given chimney was built or what condition it is in.

Will a gas insert fit an older fireplace? Five checks in order

A gas insert is a closed, glass-fronted heater set inside the masonry fireplace you already have, with its exhaust carried up through the chimney. Before anyone picks a model, a short sequence of checks decides whether the plan works for your fireplace.

  1. Measure the fireboxEvery insert's installation manual lists a minimum opening: height, front width, back width and depth. The Kozy Heat Nordik 34i manual, as one example, calls for an opening at least 23-3/4 inches high and 34-1/8 inches wide at the front. A shallow or sharply tapered firebox can rule out some models while leaving others possible.
  2. Check the flue size and conditionThe same manual sets a minimum inside size for the masonry flue (6 by 8 inches), because the insert's vent pipes have to pass through it. A camera inspection shows cracked or offset tiles, ledges and debris that could block the run.
  3. Clean the chimney before installationThe Nordik manual tells the installer to verify the chimney is clean and in good working order, and to clean it so creosote odor does not come into the house. Years of wood smoke do not disappear because the fuel changes.
  4. Decide what happens to the damperInsert manuals typically allow the old damper to be removed or blocked fully open so the vent pipes can pass. The Nordik manual permits either.
  5. Confirm the gas supplyWe connect inserts to an existing gas line only. Where the fireplace has no gas line yet, a gas contractor has to bring one there before the insert goes in.

Why the vent pipes run all the way to the chimney top

Most direct-vent gas inserts do not breathe through the open masonry flue. They use a pair of vent pipes: one brings outside air down to the burner and the other carries exhaust up and out through a termination at the top. Some systems run the two as separate flexible pipes (co-linear venting), and some nest one pipe inside the other (co-axial). The Nordik manual describes an adapter for converting between the two, with a required one-inch clearance to combustibles around the co-axial pipe.

Because the pipes become the exhaust path, the masonry around them still has a job. The crown has to support the termination and shed water, and the brick and flashing have to keep rain out of the chimney. Relining and adding a different type of appliance both appear on CSIA's list of reasons for a Level 2 inspection, so an insert project is a natural time for a full look at the chimney. Our fireplace insert installation page covers the work itself, and gas logs vs. gas inserts sets the insert beside the simpler gas log option.

Local questions

Our 1970s fireplace shares a chimney with the furnace. Can it still take a gas insert?

Often the fireplace and the furnace each have their own flue inside the same chimney, and the insert uses only the fireplace flue. An inspection confirms which flue is which and whether the fireplace flue is large enough and sound enough for the insert's vent pipes.

Does the chimney need cleaning if we are giving up wood?

Yes. Insert manuals ask for a clean chimney before installation. Leftover creosote can cause odors and leaves deposits in the flue the new vent pipes pass through.

Can an insert use the gas line that feeds our gas logs?

An existing line is the starting point, but the insert's manual sets the gas supply requirements and the line has to meet them. If no line reaches the fireplace, a gas contractor installs one before we connect the insert.

Is a gas insert the same thing as gas logs?

No. Gas logs sit in the open fireplace and send exhaust up the existing flue with the damper open. An insert is a sealed unit with its own venting, built to heat the room.
