The purpose of this manual is to give the contractor guide­lines for installing the Lifebreath Clean Air Furnace. All national and local codes relating to this type of equipment must be followed.
Locating The Unit
The Clean Air Furnace is designed to be installed vertical­ly, in a conditioned space,where the surrounding temperature does not fall below 50°F (10°C). Attic installa­tions are not recommended. Typically the unit is installed in a mechanical area of the basement, or other partitioned mechanical room, elsewhere in the home.
A location close to an outside wall is recommended, as the ventilation supply and exhaust portion will need to be ducted to the outside air.
Sufficient clearance around the unit is required for service of the filter, heat recovery core and components.
Duct Connections
To accommodate various installations, the Clean Air Furnace has knockouts for the return air plenum and ven­tilation ducts, on both sides of the cabinet. Special care and attention should be given to determining which knock­outs are to be removed. (See Fig. 2 & Fig. 3).
Slide Heat Recovery Core out to remove ventilation knockouts. Never install ductwork directly to the cabinet that is smaller than the opening provided.
Figure 2 Option1-Ventilation Ports Off Left Side
NOTE: Return plenum opening can be on either side of cabinet and is not dependent on which side the ventilation ports are on.

Penetrations from sheet metal screws used to fasten the ductwork to the cabinet of the unit should only be placed into the duct flange provided. This is to avoid contact and damage of the heating/air conditioning coils and internal wiring.
Ducting
The duct sizing for the furnace section can be determined using HRAI Residential Air System Design Manual, SMACNA, or any other industry-recognized manuals.
Any ductwork running through unconditioned space must be sealed properly and insulated to prevent heat loss. All local codes must be followed in determining the amount of insulation needed.
The ventilation section consists of two 6" (15.2cm) round ports located on the side of the cabinet, which vent to the outside. Insulated ducting with a vapour barrier such as flex-ducting, or ridged pipe wrapped in pipe sleeve, is required to prevent condensation from occurring on the pipe. Also the airflow in these lines is designed to be bal­anced. (See "Balancing Airflows" in this manual, for damper location and procedure.)
Warning: A backdraft damper is required in the exhaust air duct to prevent cold air from entering the unit when the Clean Air Furnace is not running. Fig. D Page 9.
Locating Intake Weatherhood
The intake weatherhood should be located as follows:
* 4-6' from ventilation exhaust hood, and upstream of
prevailing winds, if possible.
* At least 6' from a dryer vent, oil fill pipes, combustion
outlets, gas meters, garbage containers or anything else, which may contaminate the air.
* Do not locate fresh air intake in garages, crawl
spaces or attics.
* Install 18" above grade, or above expected snow
accumulation.

Locating the Exhaust Weatherhoods
The Exhaust Weatherhood should be located as fol­lows:
* At least 4-6' from the supply inlet.
* At least 18" above grade or expected snow accu-
mulation.
* At least 3' from gas meters, combustion vents, or
dryer vents.
* Do not install in garages, crawl spaces or attics.
Outside Ducting the Weatherhoods
The ventilation portion of the Clean Air Furnace can be vented off either side of the unit by removing knockouts provided. Once the knockouts in Fig. 2 / Fig. 3 are removed, a bead of silicone can be placed on the plastic thermo-collars (provided), to form a seal between the collars and the cabinet. The collars can then be fas­tened into place with screws. Note the exhaust outlet is always the port on the bottom, and the supply inlet is always the port on the top, both ports should be labeled from the factory as such.
A small piece of rigid duct (1-2') can be fabricated for joining the outside ducting to the port collars. (Fig. D, page 12). This section of pipe is needed to accommo­date the balancing damper, as required in the "Balancing Procedure" in this manual. After installing the dampers, the small section of pipe can be fastened to the port collars. The ductwork from the outside weatherhoods to the unit, is usually flexible ducting, although rigid pipe may be needed if the runs are greater than 20 feet. In either case the pipes (both exhaust and supply and the added fittings) must be insulated, with a complete vapor barrier Fig. 4. To mini­mize restriction in airflows the ducting should be short, with as few bends as possible. See diagram below for recommended connection of insulated ducting to out­side weatherhoods and the Clean Air Furnace port collars.

Pitot Tube Air Flow Balancing
It is necessary to have balanced air flows in an HRV. The volume of air brought in from the outside must equal the volume of air exhausted by the unit. If the air flows are not properly balanced then:
* The HRV may not operate at its maximum efficiency * A negative or positive air pressure may occur in the house * The unit may not defrost properly * Failure to balance the HRV may void warranty
Prior to balancing, ensure that:
1. All sealing of the ductwork system has been completed.
2. All of the HRV's components are in place and functioning properly.
3. Balancing dampers are fully open.
4. Unit is on high speed.
5. After taking readings of both the stale air to the HRV duct and fresh air to the house duct, the duct with the lower CFM ([L/s] velocity) reading should be left alone, while the duct with the higher reading should be dampered back to match the lower reading.
6. Return unit to appropriate fan speed for normal operation.
Balancing Procedure
The following is a method of field balancing an HRV using a Pitot tube, advantageous in situations when flow sta­tions are not installed in the ductwork. Procedure should be performed with the HRV on high speed.
Choose the straightest section of duct between the HRV and the weatherhoods. This will be used for both the sup­ply and return ducts.
Drill a small hole in the duct (about 3/16"), three feet downstream of any elbows or bends, and one foot upstream of any elbows or bends. These are recommend­ed distances but the actual installation may limit the amount of straight duct.
The Pitot tube should be connected to a magnehelic gauge or other manometer capable of reading from 0 to
0.25 in. (0 - 62 Pa) of water, preferably to 3 digits of reso­lution. The tube coming out of the top of the Pitot is connected to the high pressure side of the gauge. The tube coming out of the side of the Pitot is connected to the low pressure or reference side of the gauge.
Insert the Pitot tube into the duct, pointing the tip into the airflow.
Installation

For general balancing it is sufficient to move the Pitot tube around in the duct and take an average or typical reading. Repeat this procedure in the other (supply or return) duct. (Fig. B.). Determine which duct has the highest airflow (highest reading on the gauge). Then damper that airflow back to match the lower reading from the duct. The flows should now be balanced.
Actual airflow can be determined from the gauge reading. The value read on the gauge is called velocity pressure.
The Pitot tube comes with a chart that will give the air flow velocity based on the velocity pressure indicated by the gauge. This velocity will be either feet per minute or metres per second. To determine the actual airflow, the velocity is multiplied by the cross sectional area of the duct being measured.
This is an example for determing the airflow in a 6" duct. The Pitot tube reading was 0.025 inches of water. From the chart, this is 640 feet per minute.
The 6" duct has a cross sectional area of:
= (3.14 x [6"÷12]2)÷4 = 0.2 square feet
The airflow is then 640 ft./min x 0.2 square feet = 128cfm
For your convenience, the cross sectional area of some common round duct is listed below:
DUCT DIAM. (inches) CROSS SECTION AREA (sq. ft.)
5.0 .14
6.0 .20
7.0 .27
The accuracy of the airflow reading will be affected by how close to any elbows or bends the readings are taken. Accuracy can be increased by taking an average of multi­ple readings as outlined in the literature supplied with the Pitot tube.

In order for any appliance to work properly it must be set up and tested by a knowledgeable technician.
The following conditions must be met prior to start-up
1. Blower wheel rotates freely inside its housing.
2. Wiring connections are tight.
3. Water is sitting in the "P" trap below the HRV core.
4. All duct and pipe connections are sealed.
5. Front access door is on tight.
1. Turn on power supply to Clean Air Furnace. Caution: The blower will start running at a lower speed.
2. Switch the room thermostat to heat. The thermostat should be set higher than the current room temperature in order to energize the unit and commence the heating cycle.Verify heat cycle starts.
3. Set room thermostat at desired temperature setting.
4. Switch fan to manual at the thermostat so the unit will run at high speed in order to perform the balancing pro­cedure on the ventilation section.
Note: For ECM motors, refer to note located on this page regarding high speed fan operation.
5. After balancing the ventilation according to instructions, set the thermostats fan switch to "auto". On "auto" the fan will run continuously at a low speed if the ventila­tion switch (fig. 6) is in the continuous mode, until heating or cooling is called for and then will switch to a higher speed. On "manual" the fan will run at high speed continuously.
NOTE: Continuous low speed can be turned ON/OFF
with the ventilation switch, (fig. 6).
NOTE: Continuous high speed can be obtained by
switching thermostat fan switch to manual/on.
NOTE: For models with the ECM blower motor. Low
speed fan is controlled by the thermostat fan switch (R and G terminals).
High speed blower operation is obtained by making a dry contact closure across R and the Orange wire from the ECM motor.
Start Up Procedure
NOTE: Downflow models incorporate a flow
switch to verify blower operation and air­flow. If airflow is not sensed or the pressure switch is blocked, the electric heating elements will NOT start. NEVER override or disable safety switches. If air­flow is blocked or too low, the airflow MUST be diagnosed and corrected.
Page 13
Heating/Cooling
When the room thermostat calls for heat, the furnace blower switches on to heating speed and will start circu­lating 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 ele­ments 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 (optional A 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 low speed. Continuous low speed is selec­table, (fig. 6).
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. 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 as it is not required for air conditioning operation. To increase humidity a quality humidifier should be added to the sys­tem.
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.

Lack of heat
1. Check that the room thermostat is set to the desired temperature.
2. Ensure there is power to the unit.
3. Verify that the airflow in and out of the system matches designed specs. If airflow is low, check for blockage in the filter or some other obstruction.
HRV core freezes up
1. Make sure that the supply and exhaust lines are bal­anced according to the "Balancing Procedure" in this manual.
2. If out of balance, ensure that the balancing dampers have not been moved and that there are no obstruc­tions in the outside hoods.
3. If necessary, install optional defrost kit, according to instructions.
Water sits in drain pipes
1. Check drain pans or lines for plugs.
2. Confirm that the HRV core is installed according to
manufactures recommendations.
3. Check the drain line for kinks.
4. Make sure that the O-ring in the drain nozzles sit flat.
5. Ensure the drain line has enough "fall" to it.
Condensation/ice forming inside ventilation ducts
A rip in the vapor barrier or poorly sealed joints may cause condensation or ice to form on the ducting. If this occurs, replace the entire line.
Humidity levels are too low
1. If you have installed a dehumidistat ensure that its set­ting is correct.
2. Check humidifier settings.
3. Change thermostat fan switch from manual to automat­ic.
4. Change ventilation switch on furnace from continuous (low) to automatic.
Humidity levels are too high
1. If you have installed a dehumidistat ensure its setting is correct.
2. Install a dehumidistat if necessary
3. Change ventilation switch on furnace from automatic to continuous.
4. Change thermostat fan switch from automatic to manual.
