Note 1. Do not install on carpeting.
When installed according to the listed minimum clearances from combustible construction mate-
rials, the Raypak heaters can still be serviced without removing permanent structural construc-
tion around the heater.
However, for ease of servicing, we recommend a clearance of at least 24” in front, and at least
18” on the water connection side. This will enable the heater to be serviced in its installed
location, that is, without movement or removal of the heater.
Clearances less than minimum, 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.
