property damage, severe injury, or loss of life.
The dehumidifier/air handler and all other gas
appliances sharing the gas supply line must be firing at
maximum capacity to properly measure the inlet
supply pressure. The pressure can be measured at
the supply pressure port on the inlet manual ball valve.
Low gas pressure could be an indication of an
undersized gas meter, undersized gas supply lines
and/or an obstructed gas supply line. The
dehumidifier/air handler unit is equipped with low and
high gas pressure switches that are integrally vent
limited. These types of devices do not require venting
to atmosphere
