Code, the International Building Code, and
local building, plumbing, and waste water
codes. In the absence of local codes
installation must conform
to current
National Fuel Code ANSI Z223.1/NFPA 54
or the National Gas & Propane Installation
Code CSA B149.1, and CSA B52
Mechanical
Refrigeration Code. All

heating or cooling at any time during
any phase of construction. Very low
return air temperatures, harmful
vapors, and misplacement of the
filters will damage the unit and its
efficiency.
