Installation
AAON equipment has been designed for
quick and easy installation. Startup and
service must be performed by Factory
Trained Service Technician.
The V3 unit can either be shipped assembled
or shipped in sections. See the Unit
Assembly section of this document for
instructions on assembling the sections.
Locating the Unit
Placement of the unit relative to ductwork,
electrical and plumbing must be carefully
considered. Return air plenum or duct can be
mounted directly to the return air flanges.
Use flexible gasket material to seal the duct
to the unit.
Verify floor, foundation or suspension
support can support the total unit weight,
including accessory weights. Unit must be
level in both horizontal axes to support the
unit and reduce noise and vibration from the
unit.
Gas fired unit combustion air inlets and vent
(flue) gas discharges are located on the front
of the unit. See Figure 2. There must be
18 inches of clearance between the front of
the V3 and building walls or equipment. If
equipment is for replacement and required
clearances are not available, contact AAON
for recommendations.
Figure 2 - High Efficiency Gas Heater
Flue discharge vents must be located
at least 120 inches away from any
opening through which combustion
products could enter the building.
