FUEL TANK INSTALLATION

The fuel tank must be purchased separately and installed by a qualified fuel supply technician.

NOTE: Fuel tank installation must comply with locally applicable codes. Check with local

building officials.

NOTE: Keep the fuel tank away from direct sunlight, high temperature, dust, rain and fire, and

take preventive measures against falling during an earthquake.

NOTE: The fuel tank should be installed on non-flammable objects, and kept level to prevent

the unit from falling or shaking.

NOTE: The fuel tank should be installed on a base finished with non-flammable objects

(concrete, mortar or block). The legs of fuel tank should be secured with anchor bolts (4

locations) to prevent falling or shaking.

FUEL PIPE INSTALLATION

Insert the rubber fuel hose to the fuel valve connected with the fuel tank, and tighten by the

hose band.

NOTE: Do not apply heavy pressure on the fuel hose. To prevent an air lock in the fuel line,

the fuel line should not be deformed.

NOTE: Only regular pipe should be used as a fuel pipe.

NOTE: To install a rubber fuel hose, if the bending radius is too small, cracks will occur in a

short time because of stress on the inside of the rubber, and an oil leakage may occur.

Be sure to maintain a bending radius more than 100 mm, and avoid torsion.

NOTE: Select a place protected from direct sunlight. When the rubber fuel hose is exposed to

UV rays, degradation will be accelerated.

NOTE: For outdoor installation, be sure to use a metal pipe (copper pipe with an external

diameter of 3/8 in.) as a fuel pipe.
