Your furnace is a gas appliance.
It is critical that the gas
supplied to the unit be completely burned to avoid the pro-
duction of carbon monoxide gas. Complete combustion of
the gas requires, but is not limited to, correct gas pressure
and gas flow rate, adequate combustion, air, and proper
venting.
WARNING
Carbon monoxide gas is invisible, odorless and toxic.
Exposure to carbon monoxide gas can cause personal injury
and even death to all occupants, including pets. Any item
that is powered by or gives off heat from a combustion
process (including lawn mowers, automobiles, and fire-
places) has the potential to produce carbon monoxide
gas. Because of this,
Lennox recommends the use of
a carbon monoxide detector in your home, even if
you do not own gas appliances.
Reliable detectors are
available at reasonable retail prices. Contact your Lennox
dealer for more details about this investment in your safety.
Your furnace is designed to meet standards set by national
agencies, and to operate safely when properly installed and
maintained. However, the unit’s performance can be great-
ly impacted by the individual installation and the operating
environment. It is your responsibility to ensure that this
appliance is maintained. Proper maintenance is critical for
your safety and the satisfactory operation of the product.
Lennox strongly recommends annual inspection and
maintenance of this appliance.
Contact your Lennox
dealer for an inspection by a licensed professional service
technician (or equivalent).
DANGER
Danger of explosion.
There are circumstances in which odorant used with LP/
propane gas can lose its scent. In case of a leak, LP/
propane gas will settle close to the floor and may be
difficult to smell. An LP/propane leak detector should be
installed in all LP applications. Do not attempt to bleed
the gas lines of air. Call your local gas provider.
Start-Up & Operation Information
WARNING
If you do not follow these instructions exactly,
a fire or explosion may result causing
property damage, personal injury or death.
BEFORE PLACING THE UNIT INTO OPERATION,
smell
all around the appliance area for gas. Be sure to smell
next to the floor because some gas is heavier than air and
will settle on the floor.The gas valve on the EL195DF will
be equipped with a gas control switch. Use only your hand to
move the switch. Never use tools. If the switch will not move
by hand, do not try to repair it. Call a licensed professional
service technician (or equivalent). Force or attempted repair
may result in a fire or explosion.
Placing the EL195DF furnace into operation:
EL195DF units are equipped with an ignition system. Do not
attempt to manually light burners on this furnace.
Each time the thermostat calls for heat, the burners will auto-
matically light. The ignitor does not get hot when there is no
call for heat on units with this ignition system.
