Remember the wall-vented, gas-fired space heaters with standing pilots? It sure was fun trying to relight those pilots through the peephole on windy days — not.
I had one customer who heated their entire home with gas-fired heaters that resembled window air conditioners. They were as old as dirt and suffered constant breakdowns. One bitter-cold winter, I talked them into replacing several instead of repairing, and ordered four new units. Meanwhile, they froze to death while waiting. I got a call from the distributor that the units had arrived, called my customer and they were jumping for joy, I headed to the distributor only to find they had been sold to another mechanical contractor just minutes before I arrived! To say my customer was madder than a wet hen would not do his rage justice. I had to reorder and installed them several weeks later.
