Introduction

Congratulations on your selection of the LIFEBREATH Clean Air Furnace (CAF). This is a very advanced unit that combines the outstanding efficiency and economy of the water heater/airhandler concept, plus the tremendous health benefits of year-round fresh air ventilation in every room of your house.

With the addition of LIFEBREATH Turbulent Flow Precipitator (TFP) Air Cleaner (optional) you will have the ultimate in comfort and healthy indoor air quality.

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 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 furnace. 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 Clean Air Furnace 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.

HRV - Aluminum Core

A Heat Recovery Ventilator (HRV) is designed to provide fresh air into a building while exhausting an equal amount of stale air. During the winter months, the incoming cold fresh air is warmed by utilizing the heat recovered from the stale air before it is exhausted to the outdoors. During summer months when the indoor space is air conditioned, the Heat Recovery Ventilator will help in cooling the incoming fresh air with the stale air that is being exhausted.

ERV - Enthalpic Paper Core

An Energy Recovery Ventilator (ERV) is designed to provide fresh air into a building while exhausting an equal amount of stale air. An ERV is designed for use in warm humid areas with heavy air conditioning use. The ERV will transfer both sensible and latent heat from the incoming fresh air to the outgoing stale air thereby reducing the load (due to ventilation) on the air conditioning system.

ERVs are not suitable for climates where the temperature drops below -4˚C (25˚F).
