2.How to connect air intake hose.

Screw one air intake hose into socket of the appliance’s main air intake hose. If this is not long enough then join air intake hoses together by screwing them both half way into a hose joint socket.

Important: The PVC air line is longer than the flue line and may need to be cut down to size. Be sure to thoroughly debur all rough edges.
