LOCATION

Use the following guidelines to select a suitable loca-
tion for these units.
1. Unit is designed for outdoor installation only.
2. Condenser coils must have an unlimited supply of
air.
3. Where a choice of location is possible, position the
unit on either north or east side of building.
4. For ground level installation, use a level concrete
slab with a minimum thickness of 4 inches. The
length and width should be at least 6 inches
greater than the unit base rails. Do not tie slab to
the building foundation.
5. Roof structures must be able to support the weight
of the unit and its options and/or accessories. Unit
must be installed on a solid level roof curb or
appropriate angle iron frame.
6. Maintain level tolerance to 1/2 inch maximum
across the entire length or width of the unit.
Excessive exposure of this furnace to contami-
nated combustion air may result in equipment
damage or personal injury. Typical contami-
nates include: permanent wave solutions, chlo-
rinated waxes and cleaners, chlorine based
swimming pool chemicals, water softening
chemicals, carbon tetrachloride, Halogen type
refrigerants, cleaning solvents (e.g. perchloro-
ethylene), printing inks, paint removers, var-
nishes, hydrochloric acid, cements and glues,
antistatic fabric softeners for clothes dryers,
masonry acid washing materials.
If a unit is to be installed on a roof curb or special frame
other than a YORK roof curb, gasketing must be
applied to all surfaces that come in contact with the unit
underside.

RIGGING AND HANDLING

Exercise care when moving the unit. Do not remove
any packaging until the unit is near the place of installa-
tion. Rig the unit by attaching chain or cable slings to
the round lifting holes provided in the base rails.
Spreaders, whose length exceeds the largest dimen-
sion across the unit, MUST BE USED. Refer to
Figure 1.

Units may also be moved or lifted with a forklift, from
the side only, providing that an accessory skid is used.
LENGTH OF FORKS MUST BE A MINIMUM OF 90".
Refer to the Physical Data Table 7 for unit weights and
to the Figure 2 for approximate center of gravity.
Before lifting a unit, make sure that all panels
are in place and that its weight is distributed
equally on all cables so it will lift evenly.

and service. Installer must make provisions for ade-
quate combustion and ventilation air in accordance
with Section 5.3, Air for Combustion and Ventilation of
the National Fuel Gas Code, ANSI Z223.1 (in U.S.A.)
or Sections 7.2, 7.3 or 7.4 of Gas Installation Codes
CSA-B149.1 (in Canada) and/or applicable provisions
