Wiedmann suffered burns to 54 percent of his body and has undergone 10 operations, all of which required skin grafts.
Wiedmann was rescued in the fire by his colleagues, desperate to save his life, after a mayday call sent them scrambling.
There had been reports that someone was trapped, and Wiedmann and firefighter James Gersbeck were both badly burned during the search.
What they did not know is that the tenants were not home at the time of the fire.
