High Altitude Derate; Propane Gas Conversion - Maytag Amana MES80 Series Manual

CONTACTOR COILS
NOTES:
1. ISOLATING RELAY MAY BE ELIMINATED IF LINE VOLTAGE
SUPPLY TO FURNACES IS THE SAME PHASE .
TO VERIFY PHASING:
A) VERIFY SOURCE IS EXACTLY THE SAME EITHER L1, L2,
OR L3 FROM THE SAME TRANSFORMER OR
B) CHECK WITH SCOPE OR PHASE METER
C) IF IN DOUBT USE RELAY
2. IF ISOLATING RELAY IS NOT USED, CONNECT FURNACE "W" TERMINALS TOGETHER.
not exceed the rated input shown on the rating
plate. Overfiring of the fur nace can result in
premature heat exchanger failure. Gas pressures
in excess of 13 inch es water column can also cause
permanent damage to the gas valve.
At all altitudes, the manifold pressure must be within 0.3
inches w.c. of that listed in the Specification Sheet applicable
to your model for the fuel used. At all altitudes and with either
fuel, the air tempera ture rise must be within the range listed
on the furnace nameplate. Should this appliance be convert-
ed to LP, refer to the instructions included in the factory au-
thorized LP conversion kit.

High Altitude Derate

IMPORTANT NOTE: The furnace, as shipped, re-
quires no change to run between 0 - 5500 feet. Do
not attempt to increase the fir ing rate by changing
orifices or increasing the manifold pressure be-
low 5500 feet. This can cause poor combustion and
equipment failure.
High altitude installations above 5500 feet may require both
a pressure switch and an orifice change. These changes are
necessary to compensate for the natural reduction in the
density of both the gas fuel and the combustion air at higher
altitude.
For installations above 5500 feet, please refer to your dis-

tributor for required kit(s).
All conversions must be performed by a qualified installer, or
service agency.

Propane Gas Conversion

Possible property damage, personal injury or death may
occur if the correct conversion kits are not installed. The
appropriate kits must be applied to ensure safe and proper
furnace operation. All conversions must be performed by a
qualified installer or service agency.
This unit is configured for natural gas but may be converted
for use with L.P. gas by installing the specified L.P. conver-
sion Kit.
If converting to LP gas, it is recommended that an LPLP0* kit
also be installed. The use of this kit will prevent the furnace
from firing when the LP gas supply pressure is too low to
support proper combustion.
