WARNING
• Check that the ground wire is securely connected.
Do not connect ground wiring to gas piping, water
piping, lighting conductor, or telephone ground wiring.
• If a circuit breaker, fuse or safety sensor is frequently
activated, i.e. rapid red flashes, shut down the system
and contact your service contractor. Please follow all
instructions provided in this manual. Any disregard of
the steps outlined in this manual is taken at the user's
own risk.
WARNING
Unauthorized modifications to Johnson Controls
products are prohibited as they:
- may create hazards which could result in death,
serious injury or equipment damage.
- will void product warranties.
- may invalidate product regulatory certifications.
- may violate OSHA standards.
WARNING
Use appropriate personal protective equipment,
such as gloves and protective goggles and, where
appropriate, have a gas mask nearby. Also, use
electrical protection equipment and tools suited for
electrical operation purposes. Do not touch or adjust
any safety devices inside the indoor or outdoor units.
All safety features, disengagement, and interlocks
must be in place and functioning correctly before the
equipment is put into operation. If these devices are
improperly adjusted or tampered with in any way, a
serious accident can occur. Never bypass or wire
around any safety device.
Specific safety rules and precautions
•
Only natural gas or propane (LP) gas are approved for
use with this furnace.
•
Only install this furnace in a location and position as
specified in this manual.
•
Only install a gas-fired furnace in a residential garage
as specified in this manual.
•
Provide adequate combustion and ventilation air to
the furnace space as specified in this manual.

Installation Manual: Z8ES Single-Stage Standard ECM Residential Gas Furnaces (Non-condensing Multi-position Standard
and Low NOx)
•
Only discharge combustion products outdoors. Only
connect this furnace to an approved vent system, as
specified in this manual.
•
Test for gas leaks as specified in this manual.
FIRE OR EXPLOSION HAZARD
Failure to follow the safety warnings exactly
could result in serious injury, death, or property
damage. Never test for gas leaks with an open
flame. Use a commercially available soap solution
made specifically for detection of leaks to check
all connections. A fire or explosion may result
causing property damage, personal injury, or loss
of life.
•
Always install the furnace to operate within the
furnace's intended temperature rise range. Only
connect the furnace to a duct system that has an
external static pressure within the allowable range, as
specified on the furnace rating plate.
•
When installing a furnace so that supply ducts carry
air circulated by the furnace to areas outside the
space containing the furnace, handle the return
air with ducts sealed to the furnace casing and
terminating outside the space containing the furnace.
•
It is permitted to use the furnace to heat buildings or
structures under construction where the application
and use comply with all installation instructions in this
manual, including:
-
Adequate vent installation
-
The furnace operating under thermostatic control
-
The return air duct sealed to the furnace
-
Air filters in place
-
The furnace input rate and temperature rise set
according to the rating plate marking
-
Means for providing the outside air required for
combustion
-
The return air temperature maintained between
55ºF (13ºC) and 80ºF (27ºC)
Replacing the air filter after substantial
-
completion of the construction process
-
Cleaning the furnace, duct work, and components
after substantial completion of the construction
process, and verifying furnace-operating
conditions, including ignition, input rate,
temperature rise, and venting.
•
When installing in a non-HUD-Approved Modular
Home or building constructed on-site, do not supply
combustion air from occupied spaces.
