Start-Up Procedure
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 - factory setting is continuous low speed and can be disconnected
in the electrical box if desired.
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 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. Caution: blower will start to operate at
low speed.
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.
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.)
8. 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 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.
