tent trailer heater blowing cold air

I have a 1998 Coleman Taos tent trailer. The heater was only blowing cold air, so I had the propane tank filled. The dome lights and propane stove work on battery power. (The battery is a fully charged deep cycle battery.) When the trailer is connected to outlet power (via extension cord to my house) the heater blows hot air. However, when I switch to battery power, it only blows cold air. Any idea why or what I can do to fix the problem? I'd really like to fix this myself as the nearest dealer is 2.5 hours away.
