IMPORTANT NOTE

The purpose of this manual is to act as an installation guide

only for the LIFEBREATH Clean Air Furnace.

Manufacturers' instructions for other components, such as

the water-heater/boiler, must be followed.
All national and local code requirements must be met when

installing a LIFEBREATH Clean Air Furnace. Be sure to

consult the proper authorities.

Note: Temperatures greater than 130°F (54°C) pose a seri-

ous risk of scalding individuals running domestic

hot water for potable use.

This appliance complies with IAS Canada Inc. Requirement

CR95-003, Additional Requirements for Fan Coil Units for

use with Potable Water Heaters.
All piping and components connected to this appliance shall

be suitable for use with potable water.
Toxic chemicals, such as used for boiler treatment, shall not

be introduced into the potable water heater system.
When using this system and the hot water for space heating

is set to a higher temperature than for other uses, an anti-

scald valve shall be used to ensure water for common use is

reduced in temperature to minimize a scalding hazard.

Combining two or more end uses such as space heating and

the heating of domestic hot water in a single system has the

potential to increase efficiency and reduce overall capital

costs. However, the proper design, installation, and com-

missioning of these systems are critical if these advantages

are to be realized.
This manual provides a guideline of good engineering prac-

tice in the design, installation and commissioning of

Integrated Combo Systems. The guidelines in the manual

are designed for residential forced warm air Integrated

Combo Systems which utilize domestic water heaters or

boilers and the LIFEBREATH furnace. Heating and cooling

loads shall be calculated in accordance with recognized

Residential Heat Loss and Heat Gain Calculation methods.

Duct design shall comply with recognized Residential Air

System Design methods. This manual provides worksheets

to be used for the purpose of sizing residential water heaters

and the combo furnace.
The LIFEBREATH Clean Air Furnace is a volume ventila-

tion system. Use the optional Lifebreath Bathroom Exhaust

System Kit (Part 99-CAF-BESKIT) if you wish to exhaust

from specific locations such as bathrooms.

Description and Purpose

Operation Heating/Cooling

When the room thermostat calls for heat, it activates a cir-

culation pump located inside the Clean Air Furnace. This

pump delivers hot water from the water heater, through the

furnace coil and back to the water tank. Simultaneously, the

furnace blower switches on to high speed and will start cir-

culating air across the coil, which picks up heat and delivers

it to the rest of your home.
Once the thermostat's temperature is reached the pump will

shut off, and the blower will return to its pre-set speed or

off.

Note: When the furnace blower is left running on low

speed the air in the home circulates continuously. When

the heat is called for the blower will automatically switch

to a higher speed. After the required hot air has been

delivered the blower will switch back to low speed.

When the thermostat calls for cooling (evaporator coil and

condensing unit required), the furnace blower activates to

high speed and the outdoor condenser unit is energized.

After the thermostat temperature is reached, the condensing

unit will shut off and the blower will return to its preset

speed or off.

Ventilation

The heat recovery ventilation (HRV) portion of the Clean

Air Furnace, is automatic. Once set, a desired amount of

fresh air will be drawn into the home while the furnace

blower is activated.
To reduce humidity, increased ventilation may be required

during heating season. An optional remote dehumidistat can

be installed. The dehumidistat will increase the speed of the

furnace blower to high and will return to its original setting

when humidity levels decrease. Your dehumidistat must be

switched off during warmer months. A quality humidifier

should be added if you wish to increase winter humidity

levels
Typically the air flow for ventilation will be set to 50 -

70cfm, for low speed furnace operation, and

100 - 150cfm at high speed. The pleated furnace filter

should be checked regularly and replaced as needed. The

HRV filter should be washed twice a year or more often if

needed.

Off Season Circulation Timer

All models are equipped with a circulation timer. It is nor-

mal operation for these models to automatically run the

circulation pump intermittently for a short period of time.
