Good Idea, Poor Execution

By
Home Inspector with JRV Home Inspection Services, LLC HOI 394

Finding good ideas gone wrong is nearly a daily experience for the home inspector

I often kid that I know enough about something to be dangerous. There are times while looking through a house that it seems that those who should know don't know what they should know with potentially dangerous results. 

Vents in fire resistant doorA basic and it seems from my perspective an often over looked requirement for heating equipment is the need for combustion / dilution air. Particularly with oil fired systems, which I see many of in Connecticut. Simply, when something, whether it be a scrap of paper or oil in a heating system is burned, it needs air for the combustion to work. If you place a glass over the burning paper it goes out. If you enclose a heating system is a small room without ventilation, it may not operate or it will function very inefficiently. 

The answer for the heating system is to provide a direct source of air for the burner. Ideally and in most instances that air should come from the exterior. 

During a recent inspection of a house built around 1980, I found the oil fired boiler installed in a small mechanical room accessible through a door from the garage. The door was open and appeared to have been left that way by the homeowner for some time judging from the amount of stuff in and around it. What almost immediately grabbed my attention were the two vents cut into the door. Seems the installer of the boiler, it was not the original unit, had known the small mechanical room would not provide the necessary air for the boiler to operate efficiently. What he did not appear know or perhaps chose to ignore (although I would like to believe it was ignorance) was the fact that the make up air in this instance can not come from the garage. Further the door that was cut is a required fire resistant door. 

Right idea, wrong method. 

Boiler in garageInterestingly the very next day I found a somewhat similar situation in a house of the very same building type. This house was older, built around 1967. The boiler was in the garage. Once again the system was not original (thankfully), and the installer had been aware of the need for combustion air. This time the air was coming directly from the exterior through a pipe mounted onto the burner. Better. However, the burner itself was at the floor. Installation requirements are that the burner should be no less than 18 inches above the floor. Being that this is a newer installation and it appears there is room to accomplish that that requirement, it begs the question, why wasn't the boiler raised? The direct air intake appears to be an attempt to make the install compliant. 

Once again good intentions gone awry. Repairs will be needed by qualified persons in both situations.

James, I enjoyed this post and have always had a great deal of respect for "Inspectors". Thankfully, the Florida inspectors now require a license and building trades qualifications.

Well done James. Hard to believe that some of these things were not known when installed.

Obviously, they had a little knowledge or they wouldn't have been able to make the installation but not very thought out! Ignorance is bliss.....

I sure hope the buyer requests these necessary changes and that the owner/sellers are smart enough to do the work.

It may had been handyman who created this dangerous situation, but I fear another culprit.  Home improvement shows all over television make major home improvements seem so easy to do, so the TV watching homeowner decides to do it himself, or herself.  Don't believe it!!  Use mechanics to make updates that might be dangerous.

I would have a lot to learn if I were selling real estate up north.  Have never even heard of an oil fired boiler.

The vents in the door don't appear to be large enough, anyway.

James Quarello now if the new installations do not follow the guidelines, its a recipe for disaster! Just wondering what code do they use when they install this.

Bob, Thanks. I feel licensing is good for the home inspection industry as a whole.

Ginny, Interesting is a word I use often :)

Tom, Yes and I have stopped trying to figure out the "why". Makes my head hurt :)

Fred, More than a little, but just not enough.

Lenn, I am very certain they will be making those requests.

Dan, Yes, I think there is that element to some of what I find here and there.

Sajy, As do we here in CT. I have really come to like gas appliances.

Paula, That's kind of funny, you being from a state that produces oil.

Alan, That's possible.

Richie, For certain. And then we add the DIY element.

Praful, There are several codes that relate to installing a heating system in a garage or in a room directly from the garage. IRC 1307.03 is one.
