SAFE INSTALLATION
REQUIREMENTS
4 WARNING
FIRE, EXPLOSION, AND ASPHYXIATION HAZARD
Failure to follow this warning could result in personal injury or
death.
Improper adjustment, alteration, service, maintenance or
installation could cause personal injury, death and/or property
damage.
Installation or repairs made by unqualified persons could result
in hazards to you and others. Installation MUST conform to
local codes or, in the absence of local codes, with codes of all
governmental authorities having jurisdiction.
The information contained in this manual is intended for use
by a qualified service agency that is experienced in such work,
is familiar with all precautions and safety procedures required
in such work, and is equipped with the proper tools and test
instruments.
NOTE: This furnace is design-certified by the CSA
International (formerly AGA and CGA) for installation in the
United States and Canada. Refer to the appropriate codes, along
with this manual, for proper installation.
¢ Use only the type of gas approved for this furnace (see Rating
Plate on unit). Overfiring will result in failure of heat
exchanger and cause dangerous operation. (Furnaces can be
converted to Propane gas with approved kit.)
Install this furnace only in a location and position as specified
in “Installation” of these instructions.
Provide adequate combustion and ventilation air to the furnace
as specified in “ Combustion and Ventilation Air” of these
instructions.
Combustion products must be discharged outdoors. Connect
this furnace to an approved vent system only, as specified in
“Vent and Combustion Air Piping” of these instructions.
Never test for gas leaks with an open flame. Use a
commercially available soap solution made specifically for the
detection of leaks to check all connections, as specified in
“Gas Supply and Piping, Final Check” of these instructions.
Always install furnace to operate within the furnace’s intended
temperature-rise range with a duct system which has an
external static pressure within the allowable range, as specified
in the Service and Maintenance manual. See furnace rating
plate.
When a furnace is installed so that supply ducts carry air
circulated by the furnace to areas outside the space containing
the furnace, the return air shall also be handled by a duct(s)
sealed to the furnace casing and terminating outside the space
containing the furnace.
¢ A gas-fired furnace for installation in a residential garage must
be installed as specified in “Installation” of these instructions.
¢ This furnace is not to be used for temporary heating of
buildings or structures under construction.
¢ This furnace is NOT approved for installation in mobile
homes, trailers or recreation vehicles.
¢ Seal around supply and return air ducts.
¢ Install correct filter type and size.
¢ Unit MUST be installed so electrical components are protected
from direct contact with water.
Safety Rules
Your unit is built to provide many years of safe and dependable
service providing it is properly installed and maintained.
However, abuse and/or improper use can shorten the life of the
unit and create hazards for you, the owner.
The U.S. Consumer Product Safety Commission encourages
installation of carbon monoxide alarms. There can be various
sources of carbon monoxide in a building or dwelling. The
sources could be gas-fired clothes dryers, gas cooking stoves,
water heaters, furnaces, gas-fired fireplaces, wood fireplaces.
Carbon monoxide can cause bodily injury and/or death. Carbon
monoxide or “CO” is a colorless and odorless gas produced when
fuel is not burned completely or when the flame does not receive
sufficient oxygen.
Therefore, to help alert people of potentially dangerous carbon
monoxide levels, you should have a commercially available
carbon monoxide alarm that is listed by a nationally recognized
testing agency in accordance with Underwriters Laboratories Inc.
Standard for Single and Multiple Station Carbon Monoxide
Alarms, ANSI/UL 2034 or the CSA 6.19-01 Residential Carbon
Alarming Devices installed and maintained in the building or
dwelling concurrently with the gas-fired furnace installation (see
Note below). The alarm should be installed as recommended by
the alarm manufacturer’s installation instructions.
There can be numerous sources of fire or smoke in a building or
dwelling. Fire or smoke can cause bodily injury, death, and/or
property damage. Therefore, in order to alert people of potentially
dangerous fire or smoke, you should have fire extinguisher and
smoke alarms listed by Underwriters Laboratories installed and
maintained in the building or dwelling (see Note below).
NOTE: The manufacturer of your furnace does not test any
alarms and makes no representations regarding any brand or type
of alarms.
To ensure safe and efficient operation of your unit, you should do
the following:
1. Thoroughly read this manual and labels on the unit.
This will help you understand how your unit operates and
the hazards involved with gas and electricity.
2. Do not use this unit if any part has been under water.
Immediately call a qualified service technician to inspect
the unit and to replace any part of the control system and
any gas control which has been under water.
3. Never obstruct the vent grilles, or any ducts that
provide air to the unit. Air must be provided for proper
combustion and ventilation of flue gases.
