Combustion and
Ventilation Air Supply
Before installing the water heater, you
must determine the amount of air
needed to supply this water heater
and any other gas appliances in the
same area and provide adequate air
for combustion and ventilation.
WARNING! This gas water heater
requires and adequate source
of clean air for combustion and
ventilation. Without sufficient air,
your water heater will have frequent
pilot outages and may emit excessive
and abnormal amounts of carbon
monoxide.
Before beginning:
For safe operation an adequate supply
of fresh, uncontaminated air must be
provided for combustion.
This gas-fired water heater is a direct
vent model. It connects directly to
the outside of the building through
the vent termination hood. The hood
operates as both the combustion air
intake and the heater exhaust port
(see Figure 4).
All combustion air is obtained from
outside the building through this
hood. Ensure the area around the
termination hood is always kept clear
and that the air supply is not exposed
to contamination or flammable
vapors.
