Frozen Exhaust Vent Terminal
If an exhaust vent terminal is blocked with ice or snow due to severe conditions, the pressure switch
and control will not allow the burner to operate. This will result in a three flash error code. Once the blockage is
removed (through melting or other means) the controls will let the burner operate. The position of the vent
terminals in relation to each other and terminals from other appliances can have an effect on the potential for
blockage due to ice or snow. See the installation instructions for recommended positioning of the terminals.
