FLAMMABLE ITEM
Flammable items or pressurized containers or any other potentially hazardous articles must never be
placed on or adjacent to the heater. Open containers of flammable material should not be stored or used
in the same room with the heater or in the area of the exterior air intake of a direct vent installation. Direct
venting does not eliminate the need to remove flammable or corrosives from the area surrounding the
heater.

Supply Gas Pressure
The supply gas pressure is normally
measured at the dirt leg or at the gas
pressure tapping on the supply side
of a gas valve. This reading must be
measured with ‘flowing’ gas.
Manifold gas pressure is measured
at the manifold pressure tap on the
outlet side of each gas valve when
the gas is flowing.
See “Gas Connections” section of
the installation and operation manual
to verify proper gas supply piping
installation.
