required in such work and is equipped with the
proper tools and test instruments.
Failure to carefully read and follow all instruc-
tions in this manual can result in furnace
malfunction, death, personal injury and/or
property damage.
NOTE: This furnace is design certified by the American Gas
Association and the Canadian Gas Association for installation in
the United States and Canada. Refer to the appropriate codes,
along with Figure 1 or Figure 2 and this manual, for proper instal-
lation.
• This furnace is NOT approved for installation in mobile
homes, trailers or recreation vehicles.
Do NOT use this furnace as a construction heater or to heat
a building that is under construction.
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 L.P. gas with approved kit.)
• Do NOT use open flame to test for gas leak.
• Ensure adequate combustion and ventilation air is pro-
vided to the furnace.
• Seal supply and return air ducts.
• The vent system MUST be checked to determine that it is
the correct type and size.
• Install correct filter type and size.
• Unit MUST be installed so electrical components are pro-
tected from direct contact with water.

SafetyRules
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 recom-
mends that users of gas-burning appliances install carbon
monoxide detectors. There can be various sources of car-
bon 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,
and several other items. Carbon monoxide can cause seri-
ous bodily injury and/or death. Therefore, to help alert
people of potentially dangerous carbon monoxide levels,
you should have carbon monoxide detectors listed by a na-
tionally recognized agency (e.g. Underwriters Laboratories
or International Approval Services) installed and main-
tained in the building or dwelling (see Note below).
B. There can be numerous sources of fire or smoke in a build-
ing or dwelling. Fire or smoke can cause serious bodily inju-
ry, death, and/or property damage. Therefore, in order to
alert people of potentially dangerous fire or smoke, you
should have fire and smoke detectors listed by Underwrit-
ers Laboratories installed and maintained in the building or
dwelling (see Note below).
Note: The manufacturer of your furnace does not test any de-
tectors and makes no representations regarding any brand
or type of detector.
C. To ensure safe and efficient operation of your unit, you
should do the 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 pro-
vide air to the unit. Air must be provided for proper com-
bustion and ventilation of flue gases.
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.
FreezingTemperaturesandYourStructure
Freeze warning.
Turn off water system.
If your unit remains shut off during cold weather
the water pipes could freeze and burst, resulting
in serious water damage.
Your unit is equipped with safety devices that may keep itfrom op-
erating if sensors detect abnormal conditions such as clogged ex-
haust flues.
If the structure will be unattended during cold weather you should
take these precautions.
1. Turn off main supply water into the structure and drain the
water lines if possible. Open faucets in appropriate areas.
2. Have someone check the structure frequently during cold
weather to make sure it is warm enough to prevent pipes
from freezing. Suggest they call qualified service agency, if
required.
