Fig. 7: Minimum Clearances from Combustible

Surfaces – Indoor Installations

When installed according to the listed minimum clear- ances from combustible construction, these heaters can still be serviced without removing permanent structural construction around the heater. However, for ease of servicing, we recommend a clearance of at least 24 in. in front, and at least 12 in. on the water connection side. This will allow the heater to be serv- iced in its installed location without movement or removal of the heater.

Service clearances less than the minimums may require removal of the heater to service either the heat exchanger or the burner tray. In either case, 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 that is less than 3 ft from the top of the heater. Three sides must be open in the area under the overhang. Roof water drainage must be diverted away from heaters installed under overhangs.
