(TCO C) John Hunter died from carbon monoxide poisoning from a gas heater that he had installed in his hunting cabin. His wife wanted to sue the manufacturer under a theory of product liability. The manufacturer claimed that the heater had been improperly installed because the vent pipe was not extended far enough above the roofline. They pointed out that the instruction manual stated that the pipe had to be vented outside but acknowledged that it did not specify how far outside the vent pipe should extend, however the manual did have a drawing that showed it extending beyond the roofline. They also pointed out that the instruction manual had the statement: WARNING; To ensure compliance with local codes, have installed by a gas or utility inspector.
