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 Figures 2 or 12 for approximate center of gravity.
CLEARANCES
All units require certain clearances for proper operation
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
of the local building codes. Refer to Figures 13, 14 and
15 for the dimensions and clearances required for com-
bustible construction, servicing, and proper unit opera-
tion.
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.

An adhesive backed label is provided over the
outside of the combustion air inlet opening to
prevent moisture from entering the unit, which
could cause damage to electrical components.
Allow this closure label to remain in place until
the combustion air hood is to be installed (refer
to Vent and Combustion Hood Figure 8).
