WARNING: Never install boiler on combustible flooring without combustible flooring pan or on carpeting as heat damage and/or fire may result.

CAUTION: Locate boiler so horizontal connecting flue pipe is as short as possible. Maximize height of vertical flue connector.

NOTE: Do not loosen tie rods on absorption unit. They accommodate thermal expansion. Loss of boiler structural integrity and water leaks/damage may result.
