Yes installing a ducted gas heater in a way that does not conform to the manufacturer’s recommendations can void the warranty. Manufacturers typically provide detailed instructions on how their heaters should be installed, including specifications for venting, clearances, accessibility for servicing and other requirements that must be met to ensure safe and efficient operation.

As you will see in the photo on this page the heater is installed with the hot flue gasses existing close to the wooden deck. The wooden deck has been scorched and is a potential fire risk. This is a photo of an actual job we attended. The heater was isolated and can no longer be used until the decking is modified.

If you choose to install a ducted gas heater yourself or have it installed by someone who is not qualified, you run the risk of voiding the manufacturer’s warranty. This means that if something goes wrong with the heater, you may be responsible for the cost of repairs or replacements.

To prevent voiding the warranty, it’s essential to follow the manufacturer’s recommendations for the installation and maintenance of your ducted gas heater. You should also have the heater serviced regularly by a qualified technician to ensure it operates safely and efficiently.
