CAUTION
Chemicals should not be stored near the heater
installation. Combustion air can be contaminated by
corrosive chemical fumes which can void the warranty.
NOTE

should be sized according to Tables 12. and 13.
Air supply requirements below apply to all
MiniMax heaters
All opening sizes are minimum and unobstructed.
