The Pulse furnace brings in gas through a gas line of its own, connected to the primary supply for the house. This line has a gas valve that opens — with orders from the thermostat — and sends a steady supply of gas to the burner when necessary.

Does a Lennox Pulse furnace have a pilot light?
The Lennox Pulse is a discontinued gas furnace with an AFUE of up to 95.5%. The unit had an automotive-type spark plug ignitor used on the initial cycle only, which helped save energy, and worked on the pulse principle, meaning it did not require a pilot burner, main burners, conventional flue or chimney.
Does Lennox still make a pulse furnace?
Lennox is no longer making the Pulse furnace or replacement heat exchanger kits. To honor their warranty, they will provide a single stage 90% equivalent furnace as a replacement, with the option to upgrade to a two stage or two stage with variable speed blower for an additional cost.
How long will a Lennox Pulse furnace Last?
Air conditioners and heat pumps last an average of 10 to 12 years, while furnaces have a life span of around 15 to 20 years, although a number of factors, including previous maintenance and the climate you live in may impact your system’s life span.
When did Lennox stop making the pulse furnace?
There are many comments on HVAC forums regarding the recall of the Pulse furnace due to leaks and cracks in the heat exchanger and secondary heat exchanger. A professional on hvac-talk.com shared a statement from Lennox in 2011 that the company would no longer be producing replacement parts for the Pulse units.
How do you light the pilot on a Lennox furnace?
Once the gas has had time to dissipate, turn the knob to “Pilot.” Then, hold down the “Reset” button and bring the flame of a long lighter close to the pilot light opening. This should light the furnace pilot light. Once you are sure the pilot light is on, release your pressure on the reset button.
How does a pulse boiler work?
The Pulse uses a thermostat system to detect temperature and begin operation. This thermostat contains much of the circuitry in the system. It closes relays and transfers sensor data so the furnace can operate within the ranges set by the house owner.
What is a pulse heater?
Pulse combustion furnaces are completely different from conventional or even energy efficient furnaces. Gas and air are drawn into a combustion chamber and ignited by an electronic spark. Between 60 and 70 pulses of the air/gas mixture are ignited per second producing rapid burning and a pressurized pulse.
Are Lennox furnace parts hard to get?
The short answer is, Yes. The availability of replacement parts of Lennox HVAC products is a bit difficult as compared to other brands. Even though Lennox products seem pretty expensive, they give the best quality for the price. If appropriately maintained, the products may not break down easily.
Are Lennox furnaces made in the United States?
