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, and several other items.

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 carbon

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 dangerous 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 technician to inspect the unit

and to replace any part of the control system and any gas con­
trol 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.
