The Lennox Conservator boiler is a gas-fired induced draft water boiler. Six sizes, all with product numbers beginning with GWB8, are available in a range of efficiency ratings from 82.0 to 84.4 percent AFUE. This boiler is designed with flexibility in mind, as it can be configured to accommodate several installation needs, including side wall venting. It also can function with either natural or LP gas.
The Conservator has an electronic ignition to minimize gas consumption. The induced draft combustion allows for efficient heat transfer as the inducer fan optimizes the flue gas rate of travel through the boiler. The unit’s efficiency is further aided by the thick fiberglass insulation within its jacket; this insulation is designed to reduce fuel consumption and minimize heat loss during the off-cycle.
This line of Lennox boilers is manufactured with a baked-on enamel finish, cast-iron heat exchangers and corrosion-resistant titanium burners. Additionally, it comes with safety features such as a pressure switch that ensures clear flue for venting. Factory testing is performed for each unit for quality assurance for consumers.
