WARNING
If the distance between the air inlet and exhaust vent terminations is too short, the water heater
will draw in the exhaust gases through the intake. There is a risk of inadequate combustion air
for the water heater, increasing Carbon Monoxide (CO) emissions and noise due to vibration.
0
Termination elbows must be oriented vertically, pointing directly downward. Attempts to prevent
exhaust air from entering the air inlet by angling termination elbows in directions other than
directly downward will increase the risk of freezing.
0
Reversing the air intake and exhaust pipes is not allowed.
Carbon Monoxide (CO) emissions and noise due to vibration will increase.
