5.Open propane supply valve on propane tank(s) slowly. Note: If not opened slowly, excess-flow check valve on pro- pane tank will stop gas flow. You may hear a click from the excess-flow check valve closing. If this happens, reset the excess-flow check valve by closing pro- pane supply valve and open again slowly.

WARNING: Be sure motor and fan are running before pushing in automatic control valve but- ton. Flames could flash outside heater if motor and fan are not running.
