WARNING
!
The blower door must be securely in place
when the blower and burners are operating.
Gas fumes, which could contain carbon
monoxide, can be drawn into the living space
resulting in personal injury or death.
Your furnace is a gas appliance. It is critical that the gas
supplied to the unit be completely burned to avoid the
production 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, odourless
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
fireplaces) 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 greatly
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 odourant
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 Lennox Merit Series™ 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 Lennox Merit Series™ furnace into
operation:
Lennox Merit Series™ 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 automatically light. The ignitor does not get hot when
there is no call for heat on units with this ignition system.
