What the numbers suggest for chimneys in Vernon

Census estimates show about 48% of Vernon's 9,118 occupied homes heating with fuel oil, 21% with utility gas, 13% with electricity, 11% with propane and 3.7% with wood. With oil this common, many chimneys in the township carry oil exhaust, and with it soot and the sulfur that comes with burning oil. Those flues are cleaned on a schedule for that reason; see oil furnace and boiler flues.

Of 10,587 housing units, about 42% date from the 1960s and 1970s and 33% from 1980 to 1999, with 6% before 1940, 10% from 1940 to 1959 and 9% since 2000. Masonry chimneys from those decades may hold a fireplace flue and a heating flue side by side, which is the subject of chimneys with more than one flue.

About 74% of units are detached houses and 12% are in buildings with five or more units, where chimneys and vents may be under an association's control. The figures outline the township and say nothing definite about any one chimney.

A new oil boiler on an older flue

Replacing oil with oil sounds like a simple swap, and the state still treats the chimney as part of the job. New Jersey's chimney verification form for replacement fuel-fired equipment, Form F370, lists "oil to oil replacement" among the cases it covers. The person signing it confirms that the chimney is sound and unobstructed, substantially free of residue from the old fuel, and lined and sized to suit the new appliance. On minor work it accompanies the permit application; on a job under a full permit, the code official sees it before the final inspection.

The new boiler may treat the flue differently from the old one. One oil boiler manufacturer's installation manual (PB Heat's WBV-e) lists chimney design, connector length, sulfur content in the fuel and flue gas temperature as factors in flue gas condensation. It requires a clay flue liner in a masonry chimney, calls for a listed corrosion-resistant metal liner if condensation occurs, and recommends one outright for its smaller models at their lower firing rates. CSIA adds that sulfur mixed with moisture is absorbed into flue tile and causes it to flake.

What to settle before installation day

1. Clean and scan the flueYears of oil soot and scale come out first, followed by a camera look at the tile and joints when the flue allows. You get the findings with photos.
2. Hand the numbers to the heating contractorInside flue dimensions, liner material and chimney height let the installer compare the flue against the new boiler's manual.
3. Decide on a liner if one is neededIf the flue is damaged, unlined or a poor fit for the new boiler, a chimney liner is the usual fix. The liner options guide compares the materials.
4. Account for anything else on the flueWhen the boiler's flue also serves a water heater, the new setup must work for both of them.

Vernon's construction permit guidance

Vernon Township's construction permits page says homeowners use the mechanical inspector's technical section when replacing water heaters, furnaces and boilers, and when installing a fireplace or a wood or pellet stove. The page also offers the chimney verification form, which it describes as verifying that an existing vent or chimney is the proper size and material for the fuel and appliance connected to it. The township's construction office can tell you which sections apply to your project.
