12. VENT RESIZING INSTRUCTIONS

When an existing furnace is removed from a venting
system servicing other appliances, the venting system
is likely to be too large to properly vent the remaining
attached appliances.
The following steps shall be followed with each of
the appliances remaining connected to the common
venting system, placed in operation one at a time
while the other appliances remaining connected to the
common venting system are not in operation.
1. Seal any unused openings in the venting system.
2. Inspect the venting system for proper size and
horizontal pitch, as required in the National
Fuel Gas code, ANSI Z223.1 or the CAN/CGA
B149 Installation Codes and these instructions.
Determine that there is no blockage or restriction,
leakage, corrosion and other deficiencies which
could cause an unsafe condition.
3. In so far as is practical, close all building doors
and windows and all doors between the space
in which the appliance(s) connected to the
venting system are located and other spaces of
the building. Turn on clothes dryers and any
appliances not connected to the venting system.
Turn on any exhaust fans, such as range hoods
and bathroom exhausts, so they will operate
at maximum speed. Do not operate a summer
exhaust fan. Close fireplace dampers.
4. Follow the lighting instructions. Place the
appliance being inspected in operation. Adjust
thermostat so appliance shall operate continuously.
5. Test for draft hood equipped appliance spillage at
the draft hood relief opening after 5 minutes of
main burner operation. Use the flame of a match
or candle.
6. After it has been determined that each appliance
connected to the venting system properly vents
when tested as outlined above, return doors,
windows, exhaust fans, fireplace dampers and
any other gas-burning appliances to their previous
conditions of use.
7. If improper venting is observed during any of the
above tests, the venting system must be corrected.

13. FRESH AIR INTAKE

All units are built with fresh air inlet slots punched in
the service panel.
The default unit is built with blank-off plates
installed. All capacity, efficiency and cost of operation
information as required for Department of Energy
"Energyguide" Fact Sheets is based upon the fresh
air blank-off plate in place and is recommended for
maximum energy efficiency.

One of several other ventilation options may be
installed. Refer to model number and/or supplemental
installation instructions.

14. CONDENSATE DRAIN

A plastic drain hose extends from the drain pan at
the top of the unit down to the unit base. There are
openings in the unit base for the drain hose to pass
through. In the event the drain hose is connected to
a drain system of some type, it must be an open or
vented type system to assure proper drainage.
15. WIRING – MAIN POWER
WARNING
For your personal safety, turn off electric
power at service entrance panel before
making any electrical connections. Failure to
do so could result in electric shock or fire.
Refer to unit rating plate for wire sizing information and
maximum fuse or circuit breaker size. Each outdoor
unit is marked with a "Minimum Circuit Ampacity".
This means that the field wiring used must be sized to
carry that amount of current. All models are suitable
only for connection with copper wire. Each unit and/or
wiring diagram will be marked "Use Copper Conductors
Only". These instructions must be adhered to. Refer
to the National Electrical Code (NEC) for complete
current carrying capacity data on the various insulation
grades of wiring material. All wiring must conform to
NEC and all local codes.
The electrical data lists fuse and wire sizes (75° C
copper) for all models.
The unit rating plate lists a "Maximum Time Delay
Relay Fuse" or circuit breaker that is to be used with
the equipment. The correct size must be used for
proper circuit protection and also to assure that there
will be no nuisance tripping due to the momentary high
starting current of the compressor motor.
The disconnect access door on this unit may be locked
to prevent unauthorized access to the disconnect. To
convert for the locking capability, bend the tab located
in the bottom left hand corner of the disconnect
opening under the disconnect access panel straight
out. This tab will now line up with the slot in the door.
When shut, a padlock may be placed through the hole
in the tab preventing entry.
See "Start Up" section for important information on
three phase scroll compressor start ups.
