6.7.5 Direct vent closet and alcove installation
For closet and alcove installation, CPVC material, instead of PVC, must be used
in a closet/alcove structure. Failure to follow this warning could result in re,
personal injury, or death.
Rinnai strongly suggests the use of concentric venting for all closet and alcove
installations. For non direct vent room air applications see sections 6.7.6 and
6.7.9.
