In order for any appliance to work properly it must
be set up and tested by a knowledgeable 
technician.

1. Ensure that connecting water lines are purged

and free of debris.
Caution: solder or other debris may cause the
furnace pump or check valve to malfunction.

2. Blower wheel rotates freely inside its housing.

3. Wiring connections are tight.

4. Water is sitting in the "P" trap below the 

HRV core.

5. All duct and pipe connections are sealed.

6. Check that styrene block is removed from

under pump.

7. Front access door is on tight.

8. Fan speed selection:

a)  

- factory setting is at

high speed and can be changed in the electri-
cal box to medium-high or medium if required.
b)  

- factory setting is continuous

low speed and can be disconnected in the
electrical box if desired.

1. Close shut-off valves separating the Clean Air

Furnace from the water heater.

2. Set up water heater according to manufactur-

er's instructions.

3. Purge air from unit. To do so, open the supply

shut-off valve to the furnace. Attach a garden
hose to drain valve, and drain water until you
get a continuous flow. Close the drain valve and
purge the pump. To purge the air from the
pump, turn the large screw on the face of the
pump counterclockwise until water leaks out,
then tighten. Open the supply shut-off valve.

4. Turn on power supply to Clean Air Furnace.

5. Switch the room thermostat to heat. The ther-

mostat should be set higher than the current
room temperature in order to energize the pump
and commence the heating cycle. (If the pump
does not start, or the Clean Air Furnace is not
producing heat, refer to the Troubleshooting
Section in this manual.

6. Set room thermostat at desired temperature set-

ting.

7. 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.
(Refer to Balancing Procedure in this manual.)
