HIGH HEAT RUNTIME: 5 min.
This menu item allows the furnace to be exercised. First, a low heat
runtime and high heat runtime are selected. Range = 5 -- 120 min.
If only the low heat is to be exercised:
The furnace will execute its ignition start--up sequence. This
sequence will be displayed on the Infinity Control screen. After the
gas valve and blower motor turn on, the screen will automatically
change to “
