Part 3 of our PVI Conquest service tip of the month is focusing on maintenance on the water heater. Please make sure a qualified individual is working on the unit, and that they are following all safety precautions.

Regular maintenance is very important for all gas-fired water heaters. This regular maintenance will ensure you get the maximum life out of the equipment. Please follow the manufacturer’s Installation, Operation and Maintenance manual for detailed instructions on maintaining the heater. If you do not have the manual for the Conquest, it can be downloaded from https://www.pvi.com/products/gas-condensing. There are two different models to choose from: the 100 or the 130-gallon tank model. Please select the appropriate size tank for your model number to get to the correct manual.
