Introduction
You will notice that the heated air in your home feels more
comfortable than air heated by a conventional furnace. One
reason for this is that LIFEBREATH's hydronically heated
air is uniform and temperate... no short blasts of hot air or hot and cold temperature spikes. In this regard, the air flowing from your hot air vents will not feel as hot to the touch as air from a conventional furnace.

With a high efficiency, adequately sized natural gas,
propane or oil hot water heater/boiler, you will always have plenty of hot water for showers and baths, washing dishes
and clothes, and all other normal domestic hot water needs.
If there is an unusually high demand for hot water, such as
filling a large hot tub, than all you need to do is allow more time for the task so the water heater/boiler can keep up to
its job of providing hot water for the heating system as well as other household uses.

Once it is correctly installed, safety will never be an issue with your LIFEBREATH air handler. No flames, fumes or
flue gases to be concerned about. Your domestic hot water
heater/boiler now provides the heat source for your furnace. This Operating and Installation Guide will help you learn
about your LIFEBREATH Air Handler quickly and easily.
The table of contents will show you where to find information on every feature of this unit along with easy to understand operating instructions. If, however, you do
encounter a question that is not covered in this Guide you
should call the LIFEBREATH dealer who installed your
furnace. Chances are that he will be able to give you a satisfactory answer but if he is unable to do so then we invite you to contact us directly.
