clearances
This water heater is approved for installation on combustible
flooring (with NSf leg kit #9003425205) in an alcove when
minimum clearance from any combustion construction are followed
as indicated in figure 6 and Table 4.
In all installations the minimum combustible clearances from vent piping
shall be 6” (152mm). Vent piping passing through a combustible wall
or ceiling must be a continuous run (no joints) and retain 6”
(152mm) clearance unless an approved reducing thimble is used.
A service clearance of 24” (610mm) should be maintained from
serviceable parts, such as relief valves, flue baffles, thermostats,
cleanout openings or drain valves.
The units are approved for installation with side, rear and ceiling
clearances as indicated below:
