Lennox Pulse Furnace

The Lennox Pulse Furnace
 
The Lenox Pulse furnace was a popular high efficiency furnace in the 1980s and 1990s. 
Furnaces installed from 1982 to 1989 were covered under a safety inspection program, released in 1997, due to the increased chances of a leaking heat exchanger.  This safety inspection program ran through to July 1st, 1999 and thus has now expired.
As a heat exchanger ages, it begins to rust.  A rusted or cracked heat exchanger could potentially leak combustion gases, including deadly carbon monoxide, into the house air.
 
As a safety precaution, anyone owning a home or considering purchasing a home with a Lennox Pulse furnace should have the heat exchanger professionally pressure tested.  This test could reveal a leaking heat exchanger (life safety issue).
 
With a typical heat exchanger life expectancy of 15-20 years, even a Lennox Pulse furnace that did not fit under the expired safety inspection program should still be pressure tested by a qualified technician.
 
Do we see these furnaces in Peterborough?  Yes, absolutely.

Lennox Heats Up Call For Consumers To Schedule Furnace Inspections - Sep 10, 1997

(DALLAS) -- Lennox Industries officials said that with cooler temperatures approaching, it is urgent that owners of Lennox Pulse furnaces installed before 1990 have those furnaces inspected.

Lennox, one of North America's leading residential and commercial heating and air conditioning equipment companies, will continue its Pulse furnace inspection program which began in April, 1997 and has already garnered over 25,000 consumer calls. The inspection program is a response to dealer reports of increased instances of corrosion in some Pulse furnace heat exchangers in units installed before 1990.

With all high-efficiency condensing furnaces, a combination of factors -- such as impurities in fuel or combustion air -- can cause corrosion of key components which could lead to potentially dangerous leaks. Furnaces which are inadequately inspected or improperly maintained can develop problems, including the possibility of carbon monoxide leaks that could be fatal.

According to Bob Schjerven, president and chief operating officer for Lennox Industries Inc., "Consumer response to the Pulse furnace inspection program has been terrific, but we need to reach everyone. We're urging all Pulse furnace owners, before they turn their thermostats from cool to heat, to call our 800 number and schedule a furnace inspection and a safety check with an independent Lennox dealer."

With each inspection, trained service technicians will perform the recommended 17-point Pulse furnace service check, conduct a visual inspection, and complete a pressure test of the unit's lifetime warranted heat exchanger. While Lennox is subsidizing participation in the inspection program, there may still be some cost to Pulse owners. Factors such as the location of the furnace, the condition of the furnace, and service unrelated to the inspection will determine the actual cost of the inspection.

If the warranted heat exchanger needs replacing, Lennox will provide a new heat exchanger at no cost to the owner. While labor costs for replacements are generally not part of the Pulse furnace warranty, Lennox will pay a reasonable allowance to the dealer for installation costs as part of this inspection program. There may be some costs to the owner, depending on the area of the country, type of installation, work required by local code requirements, and any other service required not related to the heat exchanger.

For those owners whose pre-1990 Pulse furnace has a heat exchanger which requires replacement, Lennox will provide, through the local independent Lennox dealer and at the owner's option, a $400 rebate on a new Lennox Pulse furnace. The Pulse furnace inspection program runs through July 1, 1999.

Lennox will also provide a free AIM Safety carbon monoxide detector, one of the highest quality detectors available, as part of the inspection program.

"Lennox has long been involved in a consumer carbon monoxide awareness program unrelated to this Pulse furnace inspection," explains Schjerven. "Since currently there is no device on the market that effectively shuts a furnace down if there is a carbon monoxide leak, it is important to install a carbon monoxide detector as a safeguard, in addition to annual maintenance and inspections."

Scheduling inspections: Homeowners can schedule a furnace inspection and safety check with an independent Lennox dealer by calling 1-800-537-4341. For convenience, the 800 number is staffed 24 hours a day, seven days a week. A Pulse furnace can be identified by its name on the door.

To determine whether your Pulse furnace should be inspected under this program:

1. Check for the Pulse name on the door. If the unit is a Pulse 21 furnace, it was manufactured after 1990 and is not part of this inspection program. However, as with all furnaces, annual inspections are still required.

2. Otherwise, remove the front door and look for the product identification stickers. These stickers are usually placed on the inside cabinet wall on the left side of the furnace.

3. Write down the model number that appears on the sticker (either G14 or GSR14, followed by a series of numbers and letters).

4. Write down the serial number on the product identification sticker (four numbers, followed by a letter, then five more numbers).

5. Call 1-800-537-4341 and have the model number and serial number ready.

All Furnaces Need Yearly Inspection

To maintain safety, efficiency, and reliability, Lennox recommends owners have their heating systems inspected at least once a year. The owner can extend the life of the furnace and help stop inefficient combustion and leaks, which could result in serious injuries, by:

1. Inspecting the filter monthly. Dirty filters can cause inefficient operation and could result in premature heat exchanger failure.

2. Watching for leaks and signs of deterioration. If found, call a certified service technician.

3. Insisting on a combustion efficiency test as part of the annual inspection.

Founded in 1895, Lennox Industries Inc. is an international manufacturer of air conditioning and heating equipment for residential and commercial applications. The company markets its products through a network of over 5,000 independent dealers.
