WHat else could it be?

not familier with that heater,but most gas units sequence of operation start with call for heat,combustion blower starts,pressure switch proves ,pilot(or )ignitor)fires ,proves pilot,main flame ignition.Because you have a led light blinking twice ,that is a code for a problem I would say,check the manual for what that indicates.These are somewhat general instructions so good luck.if you post the model # I can look the manual and get a better idea what kind of heater it is.
