Model UEZ gas-fired unit heaters offer a high-efficiency, separated combustion system great for space heating applications. UEZ units use outside air for combustion to prevent dirt, lint, dust or other contaminants in the indoor atmosphere from being burned. The UEZ is available in 7 sizes ranging from 55,000 to 310,000 BTUH gas input and is approved for installation in the United States and Canada by ETL.
