NOTE:
The clearances specified above must be maintained to combustibles and other materials that may be damaged by
temperatures 90ºF above ambient temperature. It is the installer’s responsibility to ensure that building materials with a
low heat tolerance which may degrade at lower temperatures are protected to prevent degradation. Clearances to
combustibles are posted on the reflector near the control end of the heater. In locations used for storage of combustible
materials where they may be stacked below the heater, NFPA 54 requires that the installer must post signs that will
“specify the maximum permissible stacking height to maintain the required clearances from the heater to combustibles.”
SunStar recommends posting these signs adjacent to the heater thermostat or other suitable location that will provide
enhanced visibility.

HANGING
The heater can be mounted with the reflector horizontal or angled up to 30º from horizontal. When the heater is to be angle
mounted, make sure the gas manifold assembly is on the lower side of the heater. Coil chains (No. 2 or larger) or rigid
supports may be used to mount the heater, which must be suspended from a permanent structure with adequate load
capacity. The gas manifold assembly tube must be level, and for angled mounting, it must be at the LOWER end of the heater.
All “S” hooks and eyebolts must be manually crimped closed by the installer.
