CAUTION
Chemicals should not be stored near the heater

corrosive chemical fumes which can void the warranty.
NOTE
The heater requires two uninterrupted air supply
openings; one for ventilation and one to supply oxygen
for proper gas combustion. The air supply openings
should be sized according to Tables 12. and 13.
Air supply requirements below apply to all
MiniMax
