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.

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 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

!
fired furnace installation (see Note below). The alarm
should be installed as recommended by the alarm
manufacturer’s installation instructions.
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
Laboratories installed and maintained in the building or
dwelling (see Note below).
