Dimension® TWO-STAGE GAS FURNACE

(New to Two-Stage Furnaces? Read This!)

Like hot cocoa, the Dimension® gas furnace keeps you nice and warm inside - only without the calories.

On a cold winter's night, there's nothing quite as comforting as being all snug and warm in your favorite blanket. Lennox has recreated that same sense of warmth and security for your entire home, with our top-of-the-line, two-stage gas furnace -- Dimension®.

Built For Life

By the time you've gone through four cars, a couple of sets of braces, several graduations, and your kids are finally leaving home, your Dimension® gas furnace will still be there keeping you comfortable.

From conception to production our furnaces go through several series of rigorous tests. We purposely subject our equipment to extreme conditions. This ensures that you will receive quality products. We are so serious about quality that we run-test each and every unit before it leaves the factory.

We are proud that Lennox quality standards are among the toughest in the industry.

Nothing Sounds Better

Have you ever missed the best line in a movie because your furnace turned on? That won't happen with the Dimension gas furnace. Extra efforts have been made to make the Dimension one of the quietest furnaces around: added insulation, a two-speed combustion blower motor and even a very low-speed continuous fan. All this to make your TV watching more enjoyable. Too bad it doesn't come with popcorn.

Breath of Fresh Air

The Dimension® furnace plays a role in battling indoor air pollution. It's a fact that 50% of all illnesses are either caused by, or are aggravated by, poor indoor air quality. To improve air circulation within the home, the Dimension furnace is equipped with a dedicated low speed for continuous fan operation. This allows more air to continuously move slowly and quietly through the system and indoor air quality products, such as humidifiers or filters.

Save Comfortably

The Dimension furnace offers more comfort for every energy dollar you spend. No matter how warm your furnace keeps you, a high energy bill will send a cold shiver up your spine. With an efficiency rating of up to 94.2%, the Dimension gas furnace not only keeps you cozy, it can reduce your energy bills when compared to older furnaces. The additional monthly savings means you'll be comfortable with the return on your investment for years to come.

This chart compares the average 3-year savings you can expect from the Dimension furnace versus older furnaces with lower efficiency ratings. Costs are based on industry averages for a typical 3-bedroom house in a city with 2,000 heating hours, with a 100,000 Btuh load, and $.63 ccf for gas. Your actual savings will vary depending on the weather, local fuel rates, and your lifestyle.

Go With a Sure Thing
SureLight™ Ignition
When it comes to safety and reliability, second best is simply not good enough. That's why Lennox has an ignition system that is the safest, surest, most intelligent hot surface ignition system available today.

The SureLight™ ignition system features an igniter made of a virtually unbreakable material -- silicon nitride. Accelerated life-cycle testing on this igniter has proven its remarkable reliability.

But the igniter is just half the story. The SureLight ignition system also features a patented "adaptive technology" control module that's intelligent enough to determine just how much energy is needed to light the burners without overheating the igniter. No other hot-surface ignition system is as reliable. That's the kind of performance, innovation, safety and reliability you've come to expect from the company you trust.

The Comfortable Way to Heat Your Home
Two-Stage Heating
Two-stage heating reduces temperature swings within your home, maintaining a consistent, comfortable and preferred temperature. Most of the time the furnace operates in the first stage or low heat for greater efficiency and comfort. On colder days, if first stage can not satisfy the heating demand, it switches to high heat or the second stage. Standard, single-stage furnaces only offer one level of heat - high.

Take Control of Your Comfort and Your Energy Bills
Variable-Speed Technology
Think of variable-speed technology as your insurance for home comfort the way you prefer it. The variable-speed technology ensures that your home receives the amount of air required to keep you and your family comfortable. While you are enjoying exceptional comfort you are also saving money on your energy bills. That's right, variable-speed motors work so efficiently that they actually consume less electricity than standard furnace motors.
