E 13 is the code for ignition failure. You can find the codes at www.monitorproducts.com. Look under service manuals. Has the heater ever burned? Make sure your fresh air pipe isn't connected to one of the two exhaust ports on the flue pipe and that the air port you are connected to isn't blocked off. May be air in the gas line if its a new install.
