Rig unit using either belt or cable slings. Use spreader bars to protect the top of the unit when it
is lifted. See
On units with a total length of less than 104 inch (2642 mm), excluding evaporative cooler, two
holes are provided in the base rail on each side of the unit. Slide pipes beneath the unit through
these holes and attach rigging to pipes for lifting the unit.
On units with a total length of a 104 inch (2642 mm) or greater, excluding evaporative cooler,
lifting lugs attached to the base rail are provided. Attach rigging to lugs for lifting the unit. For
distance between lifting lugs and total unit lengths, refer to original Submittal Sheets supplied
specified for the unit. Also see Center of Gravity and Weights Sections in this manual.

In Canada, if unit is to be installed at altitudes of 2000 feet (610 m) to 4500 feet (1372 m), each
duct furnace must have the main burners re-orificed to give 90% of the normal altitude input
rating.
If the unit was ordered from the factory for high altitude operation, confirm input rating. See
Gas Input Adjustment.
1 inch = 25.4 mm
1 foot = 0.305 m
1 gallon = 3.785 L
1 pound = 0.454 kg
1 psig = 6.894 kPa
1 cubic foot = 0.028 m 3
1000 Btu/Cu. Ft. = 37.5 MJ/m
1000 Btu per hour = 0.293 kW
1 inch water column = 0.249 kPa
liter/second = CFM x 0.472
meter/second = FPM ÷ 196.8
