ThomasPowers Posted October 8, 2012 Share Posted October 8, 2012 If the bellows inflate it is sucking air in *somewhere*. You want that to be through the inlet holes and not through the exhaust pipe as that will draw in hot gases and/or small pieces of burning fuel causing a fire inside the bellows. Your bellows should have a check valve to prevent it from inhaling through the delivery pipe. Now to tell if the bellows is pushing air out: You should be able to see the fire react to the blast of air or even hear the fire react.
