3. In case of concealed damage, carrier should be notified as soon as possible-preferably within 5 days.
4. File the claim with the following supporting documents:
a. Original Bill of Lading, certified copy, or indemnity bond.
b. Original paid freight bill or indemnity in lieu thereof.
c. Original invoice or certified copy thereof, showing trade and other discounts or reductions.
d. Copy of the inspection report issued by carrier representative at the time damage is reported to the carrier. The carrier
is responsible for making prompt inspection of damage and for a thorough investigation of each claim. The distributor or
manufacturer will not accept claims from dealers for transportation damage.
NOTE:
When inspecting the unit for transportation damage, remove all packaging materials. Recycle or dispose of the packaging
material according to local codes.
RIGGING DETAILS
IMPORTANT NOTE:
If using bottom discharge with roof curb,
ductwork should be attached to the curb prior to installing the
unit. Ductwork dimensions are shown in roof curb installation
instructions.
Refer to the Roof Curb Installation Instructions for proper curb
installation. Curbing must be installed in compliance with the National
Roofing Contractors Association Manual.
Lower unit carefully onto roof mounting curb. While rigging unit, center
of gravity will cause condenser end to be lower than supply air end.
GAS PIPING
IMPORTANT NOTE
:
This unit is factory set to operate on natural gas at
the altitudes shown on the rating plate.
The rating plate is stamped with the model number, type of gas and gas
input rating. Make sure the unit is equipped to operate on the type of
gas available. Conversion to LP gas is permitted with the use of a factory
authorized conversion kit. Contact your distributor or refer to the
specification sheet for your model for a listing of approved LP gas
conversion kit(s). Refer to the Installation Manual provided with the
LP kit for conversion from natural gas to propane gas.
The minimum supply pressure should not vary from that shown in the
Inlet Gas Pressure table because this could prevent the unit from
having dependable ignition. In addition, gas input to the burners
must not exceed the rated input shown on the rating plate. Overfiring
of the unit could result in premature heat exchanger failure.

IMPORTANT NOTE:
The gas/electric units naturally derate with altitude. Do not attempt to increase the firing rate by changing
orifices or increasing the manifold pressure. This can cause poor combustion and equipment failure. At all altitudes, the manifold
pressure must be within 0.3 inches W.C. of that listed on the nameplate for the fuel used. At all altitudes and with either fuel, the
air temperature rise must be within the range listed on the unit nameplate. Contact your distributor or refer to the specification
sheet for your model for listing of approved high altitude conversion kit(s). Refer to the Installation Manual provided with the high
altitude kit for altitude adjustments.
NOTE:
No changes are required up to 2,000 feet. Use the appropriate high altitude kit above 2,000 feet.

IPING
IMPORTANT NOTE:
To avoid possible unsatisfactory operation or equipment damage due to under firing of equipment, do not
undersize the natural/propane gas piping from the meter/tank to the unit. When sizing a trunk line, include all appliances on that
line that could be operated simultaneously.
