NOTE: DO NOT mount the heater on a vertical axis. Such installation will reduce the life of the element and will
automatically void the product’s warranty. Heater must be installed with the quartz tube horizontally level. For maximum
tube life, use a level to find the optimum position for the heater’s body. Always maintain the minimum clearances from
the heater body to any combustible materials.
