CGTH USE AND CARE MANUAL
Your heater may be installed in one of three ways: horizontal, 45° tilt left or 45° tilt right. Since the distances for the tilt installation are the same, the chart only shows one (the 45° tilt left). To determine the minimum required safe distances for your heater, you must know the mounting type and model number of your heater.

*All dimensions are from the reflector.
NOTE: All dimensions indicate the required safe distances from combustibles, dimension "C" and "E" DO NOT indicate the required mounting height. The minimum mounting height is 7' (2.1 m), except for aircraft hangars and public garages. (See Page 7, Sections 4.5.1 and 4.5.2.)
Flue clearances from combustibles are zero. It is not necessary to provide additional clearance on penetrations through the wall or roof.
