​Are all of your employees on the same page? Is there a discrepancy in terms or procedures? Does your office staff understand what your chimney technicians are trying to tell them? Does it take a long time to train new employees? These problems can be solved with the Chim-Scan® Factory Training (CSFT) class.

This class/book follows a video scanning and inspection process. Each of the five modules takes the technician from one transition point to the next. It provides an up-close view within the structure.  There is also a 17-page glossary with terms and images. The book includes over 400 photos that explain what you will see in the flue. 

How can your team be aligned if your technicians don’t agree on terms or the procedure? Is this causing confusion with your office staff? If each employee who trains a new technician uses their own terms and unique processes, this confuses the technicians and office support staff! Having streamlined training is essential to having a staff that works together.

Do your technicians understand what is happening in the flue? A cracked chimney does not always mean a chimney fire has occurred. A crack may indicate one of these causes: overfiring, chimney fire, or a seismic event. This book focuses in depth on the symptoms to look for other than cracks. There is other evidence to gather, images to capture, and analysis of how this may affect the structure. 

Highlights for the CSFT book and training:
• What is an Ideal Chimney? How does it stand up to IRC and NFPA 211?
• When do I use IRC, NFPA 211, or the appliance manufacturer’s installation instructions?
• Understanding the Levels of Inspection and Chimney Scanning
• Cracks in the flue, Thermal Stress, and Thermal Shock
• Best viewing angles for scanning – the best angle to use by defect for the best images
• The Four Pathways to Deterioration, with examples and images
• Best Access Points for scanning
• What you might find in a chimney (animals, types of soot, etc.).
• Equipment check
• Scanning patterns

Once technicians become familiar with the content in the book, they can take the Chim-Scan® Factory Trained Technician Test to achieve this designation. They will earn a certificate and a patch. A copy of the logo is also available for their use now. This will put them light years ahead of their competition and make them a source of knowledge for homeowners.

Masonry Clay Flue Tile Defects
Masonry clay flue tiles meet a harsh environment inside the chimney. Corrosive condensation, moisture, chimney fires, and other conditions may damage a flue tile. In certain circumstances, a clay flue tile can last for decades, provided they are maintained and the homeowner operates the appliance or burns responsibly.

Latent Defects are defects found within the system from improper and sometimes creative use of material that stray from building codes or the manufacturer's installation instructions. This deviation from the codes or installation instructions creates various issues within an installation.

Wear and Tear is the natural aging process where material breaks down over time. Wear and tear can also include how an appliance is operated. If it is too hot, it decreases the life of the appliance, chimney, and connector pipe. If the temperatures are too low, it can create a tar-like creosote and increase the likelihood of a Sudden Occurrence (or condensation with gas/oil). Another factor is maintenance or lack of maintenance. Wear and tear can sometimes overlap with other categories.

Moisture and Condensation damage occur when water enters the chimney interior due to a missing cap, leaking crown, cracks in the brick structure, freeze-thaw breaks in the bed or head joints, and a poor choice of brick, causing excess water absorption. Another source of water in a chimney can come from condensation. This condensation occurs when the flue gas temperature falls below the dew point. Because of the water percentage in natural gas and liquid propane, the flue gases may condense in masonry chimneys, especially those located along the home's exterior.
The next fuel to condense is wood. When the warm gases reach the masonry flue liners, they, too, cool off. The moisture is included with the other byproducts of wood burning – black creosote, watery or tarlike soot.
The last fuel, oil, will also condense on the masonry walls. Due to the higher efficiencies that oil appliances can now operate, they too will condense and, with their acidic nature, can destroy masonry clay flue tiles.

A Sudden Occurrence is a sudden event that causes damage. It can be a chimney fire, a sudden weather-related incident(s) such as a tornado, strong wind, or a seismic event. It has to be out of the ordinary of daily operations.
A Sudden Occurrence, the last Pathway, includes damage seen from a direct and sudden event. Indirect manners can apply to areas where mine subsidence has occurred (where mining was performed). Of the Pathways, this last defect(s) will usually become an insurable loss. The other three defect categories – Latent Defect, Wear & Tear, and Moisture are generally not insurable losses since insurance contracts (policies) do not include them.

​Prefabricated chimneys have been in use for decades as a Listed, accepted substitute for masonry chimneys. Prefabricated chimneys and venting product installations can vary based on the product, the installation type, and the appliance type. It’s important that these chimneys be inspected annually and cleaned. Inspecting the chimney with a Chim-Scan® Internal Evaluation System is a great way to ensure the chimney is in a continued operational condition.

All manufacturers of prefabricated chimneys test their products at a recognized laboratory to a test standard.is the creator of the test standards. Tests include several challenging factors the chimney must pass, including temperature, duration, torsion, chimney brushing, and rain tests, to name a few. 

Once the manufacturer successfully passes the test, the product installation instructions must be approved, each component properly labeled, and an agreement must be signed for random manufacturing plant inspections. Then the manufacturer is offered the Listing. 
The manufacturer may choose to offer a training program for installers. The installer's job is to install the chimney or vent, using the listed components to recreate it in the same manner as the manufacturer's installation during the testing for listing or approval. 

A new chimney pipe is shiny inside and should not have any denting or damage inside or outside. The joints should connect firmly, and all supporting components must be used. After a new chimney pipe is put into use, it must be inspected at least annually and cleaned as specified in the maintenance section. Again, the best way to see inside a series of chimney sections is with a Chim-Scan® Internal Video Inspection System.
​
With proper installation, usage, and maintenance, your prefabricated chimney system should give you years of use. After all, they have been used to vent fireplaces and hearth appliances for decades. 

Tom and Esther Urban founded a chimney-sweeping business in 1978 after they served in the Peace Corps. When they got out, it was during the oil crisis. Homeowners were installing woodstoves in old chimneys or installing them with new chimneys. Creosote rapidly built up, and chimney fires started to erupt all over the country. It was a great time to start a chimney-sweeping business, and that’s just what they did. Tom partnered with an insurance adjuster on some of his calls. It always bothered Tom and Esther that they could never obtain a clear view of what was in the flue. At this time, no chimney cameras were available to scan the flue. Tom saw the need for one and researched what it would take to build one. The search would take him to Cornell University, Ithaca, in New York State.
Tom and Esther traveled on Sunday afternoons to Cornell University to search the library’s optics section of the Thomas Registers. There were about twenty 3-inch-thick books listing almost every manufacturer in the U.S. and what they manufactured. They spent many hours copying information about everything they could foresee needing for Tom’s design. Tom then attended a security convention in New York City. After a year of research and work, he took his first camera to the 1984 National Chimney Sweep Guild Convention in Washington, DC, and the first chimney camera – the Chim-Scan®- was born. It was pronounced a “Showstopper” by CNN News Channel. However, it took years before America’s Sweeps adopted and used this critical tool.
Today, forty years later, in 2024, it’s hard to fathom a time when there was no available technology. Imagine what it would be like if the internet disappeared today. That’s what Tom Urban faced when he started researching parts to create a camera capable of being lowered into the chimney and taking a picture from several feet away.  
Eventually, sweeps started to catch on to the need for scanning chimneys. When they needed to prove there was damage to a chimney and could back it up with pictures, the insurance adjuster was more likely to approve a chimney fire claim. Over the years, many companies have sold “chimney cameras,” some of which are decent quality, some modified baby monitors, and some are lightweight consumer-grade camera systems from China or another location. But 40 years later, Chim-Scan® Cameras are still churned out from their manufacturing facility in Iowa, right in the Heartland. Unlike some other chimney camera companies, Chim-Scan® Cameras can still be repaired unless they are too old, and the parts are no longer available. Someday, when Tom and Esther decide to retire or spend time chiseling away at their bucket list, their daughter Shelley is poised to step up as President to run the Estoban Corporation, manufacturer of Chim-Scan® Cameras, the true original commercial-grade chimney sweeping camera.
