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. 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) Heating/Cooling - factory setting is at high speed and
can be changed in the electrical box to medium-high or
medium if required.
b) Ventilation - low speed is controlled by the
Thermostat Fan switch.
Once all of the necessary connections have been
made, the Clean Air Furnace Start-Up Procedure is
as follows:
1. Close shut-off valves separating the Clean Air Furnace
from the water heater.
2. Set up water heater according to manufacturer's instruc-
tions.
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 tight-
en. Open the supply shut-off valve.
4. Turn on power supply to Clean Air Furnace.
5. Switch the room thermostat to heat. The thermostat
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 setting.
