1.Safe Installation Requirements
FIRE, EXPLOSION, AND ASPHIXIATION HAZARD
Improper adjustment, alteration, service,
maintance or installation could cause death, personal injury, and/or property damage.
Installation or repairs made by unqualified persons could result in hazards to you and others. Installation MUST conform with 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 LP gas with approved kit.)
•Install this furnace only in a location and position as speci-
fied in "2. Installation"of these instructions.
•Provide adequate combustion and ventilation air to the fur-
nace as specified in "4. Combustion and Ventilation Air" of these instructions.
Combustion products must be discharged outdoors. Con- nect this furnace to an approved vent system only, as spe-
cified in "5. Gas Vent lnstallation, 6. Horizontal Venting and
7.Masonry Chimney Venting"of these instructions.
Never test for gas leaks with an open flame. Use a com- mercially available soap solution made specifically for the
detection of leaks to check all connections, as specified in "8. Gas Supply and Piping, Final Check"of these instruc- tions.
Always install furnace to operate within the furnace's in-
tended temperature-rise range with a duct system which has an external static pressure within the allowable range,
as specified in "Technical Support Manual" of these in- structions. See furnace rating plate.
•When a furnace is installed so that supply ducts carry air circulated by the furnace to areas outside the space con- taining the furnace, the return air shall also be handled by a duct(s) sealed to the furnace casing and terminating out- side the space containing the furnace.
•A gas-fired furnace for installation in a residential garage
must be installed as specified in "2. Installation"of these instructions.
•This furnace is not to be used for temporary heating of buildings or structures under construction.
See "2. Installation, Item 10'_
•This furnace is NOT approved for installation in mo-
bile 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 pro- tected 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.
A. 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 serious 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 ca rbon
monoxide levels, you should have a commercially available carbon monoxide alarm that is listed by a nationally recog-
nized testing agency in accordance with Underwriters Labora- tories Inc. Standard for Single and Multiple Station Carbon Monoxide Alarms, ANSI/UL 2034 or the CSA 6.19-01 Resi- dential 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 in- structions.
B.There can be numerous sources of fire or smoke in a building or dwelling. Fire or smoke can cause serious bodily injury, death, and/or property damage. Therefore, in order to alert people of potentially da ngerous fire or smoke, you should have fire extinguisher and smoke alarms listed by Underwriters Lab- oratories 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.
C.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 haz- ards involved with gas and electricity.
2.Do not use this unit if any part has been under water. Im- mediately call a qualified service agency 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.
