PSA for Christmas Day - Carbon Monoxide Detectors

One of the best / worst examples I can remember was a furnace we did not install, and turned out to have VERY aggressive and uncooperative owners.

The furnace had been correctly installed in an partially unfinished basement utility room along with washer / dryer/ water heater. The furnace (90+ efficient) had been correctly vented out the back wall of the house, and correctly spaced the required distance from windows or doors

The owners BUILT A VERY LARGE DECK which pretty much occupied the entire space across the rear of the house OVER THE TOP of the basement windows and the furnace vent terminations!!!

Worse, the housewife insisted on leaving the basement window open above the washer dryer, providing a path for furnace combustion products to enter back into the house!!!

The furnace vent had to be completely re worked because they are required to be pitched for condensate drainback. Because of their height position exiting the basement, there was inadequate pitch available to just extend them out to the outside edge of the deck.

The owners absolutely refused to have or pay for any proper solution. I don't remember what the outcome, but our company was not involved. Two of the most obnoxious people I remember dealing with in those years.
