Fig. 7: Minimum Installed Service Clearances — Indoor/Closet Installations

CAUTION: Service clearances less than the minimums may require removal of the heater to service either the heat exchanger or the burners.

The heater must be installed in a manner that will enable the heater to be serviced without removing any structure around the heater.

Outdoor Installations

These heaters are design-certified for outdoor installa- tion. Heaters must not be installed under an overhang unless clearances are in accordance with local instal- lation codes and the requirements of the gas supplier. Three sides must be open in the area under the over-

hang. Roof water drainage must be diverted away from heaters installed under overhangs.
