If there is no fire inside the wood stove, having a wood stove pipe in place should generally be safe, assuming the following conditions are met:
Proper Installation: The wood stove and its pipe must be installed according to the manufacturer's guidelines and local building codes. It should be placed at the appropriate distance from flammable materials and be adequately supported.
Proper Maintenance: Regular maintenance and cleaning of the wood stove and pipe are essential to ensure they function efficiently and safely.
Proper Ventilation: The wood stove pipe should be connected to a proper chimney or flue system to vent any potential harmful gases and smoke from the stove to the outside.
No Blockages: The chimney and pipe should be clear of any obstructions or blockages that could cause smoke or gases to back up into the living space.
Carbon Monoxide (CO) Detection: It's important to have carbon monoxide detectors installed in the living space to monitor for any potential buildup of this dangerous gas.
If these conditions are met, there should be no significant safety concerns with having a wood stove pipe without an active fire. However, it's always a good idea to consult with a professional and ensure that your specific installation complies with safety standards and regulations.
