1.1 Cautions and
Warnings
WARNING: The installing contractor must be certain that the area where the heater
is being installed does not contain corrosive or toxic fumes or that elements in the
atmosphere do not produce corrosive or toxic fumes in the presence of an open ame.
The chlorine atmosphere in enclosed swimming pool areas may cause burner and tube
corrosion if the area is not ventilated. ASHRAE design guides suggest a minimum of
5-6 air changes per hour. The manufacturer recommends outside combustion air. To
provide outside combustion air, Option DE2, Combustion Air Inlet Kit, must be used.
There are warning labels on the unit and throughout this manual. For your
