The model # you listed is for a vent-free, natural gas, space heater and requires no electricity to operate. Unless, you have the optional blower. If the blower accessory is what's blowing the fuses, there is a short in wiring to the blower motor. Other than that, there is nothing else about this heater, that would be blowing fuses.

Is the above, the problem you're having? If so, unplug the blower from the wall outlet, until it can be repaired or replaced. The heater will continue to operate and heat with out the blower.
