The preferred installation location is on the warm or supply side of the furnace. If that location is
not possible, the steam nozzle should be inserted a minimum of 12 in. upstream of the furnace filter.
Depending on the location and the duct rigidity, additional duct reinforcement may be necessary.

shorten the humidifier’s life.
