Gas furnace is to draw combustion air from outside. Installation allows compution air to be feed into the furnace from the left or the right and provides a plug for the unused side. With the plug installed furnace tries to run but the pilot light gets blown out. Leaving the plug out the furnace runs fine, but that means it is getting air from within my home. Inlet is per installation instructions. It is not blocked. It is not too long, only ~ 10 ft. Any ideas what is wrong? I have a repairman coming this week but it would be good to have some information for him. Tim
