CARBON MONOXIDE POISONING HAZARD  

-

 

 

Special Warning for Installation of Furnace or Air Handling Units in
Enclosed Areas such as Garages, Utility Rooms or Parking Areas

Carbon monoxide producing devices (such as an automobile, space
heater, gas water heater, etc.) should not be operated in enclosed areas
such as unventilated garages, utility rooms or parking areas because of
the danger of carbon monoxide (CO) poisoning resulting from the exhaust
emissions.  If a furnace or air handler is installed in an enclosed area such
as a garage, utility room or parking area and a carbon monoxide producing
device is operated therein, there must be adequate, direct outside
ventilation.

This ventilation is necessary to avoid the danger of CO poisoning which
can occur if a carbon monoxide producing device continues to operate in
the enclosed area.  Carbon monoxide emissions can be (re)circulated
throughout the structure if the furnace or air handler is operating in any
mode.

CO can cause serious illness including permanent brain damage or death.

ONSIDERATIONS

This furnace is approved for Category I Venting only.

Provisions must be made for venting combustion
products outdoors through a proper venting system.
The length of flue pipe could be a limiting factor in
locating the furnace.

NSPECTION

All units are securely packed in shipping containers tested
according to International Safe Transit Association specifica-
tions.  The carton must be checked upon arrival for external
damage.  If damage is found, a request for inspection by carrier’s
agent must be made in writing immediately.

The furnace must be carefully inspected on arrival for damage
and bolts or screws which may have come loose in transit.  In
the event of damage the consignee should:

1. Make a notation on delivery receipt of any visible damage

to shipment or container.

2. Notify carrier promptly and request an inspection.
3. With concealed damage, carrier must be notified as soon

as possible -  preferably within five days.

4. File the claim with the following support documents within

a nine month statute of limitations.

Original or certified copy of the Bill of Lading, or
indemnity bond.

Original paid freight bill or indemnity in lieu thereof.

Original or certified copy of the invoice, showing trade
and other discounts or reductions.

Copy of the inspection report issued by carrier’s
representative at the time damage is reported to carrier.

The carrier is responsible for making prompt inspection of dam-
age and for a thorough investigation of each claim. The distribu-
tor or manufacturer will not accept claims from dealers for trans-
portation damage.

Keep this literature in a safe place for future reference.
