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 electri- cal 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 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.

Caution: blower will start to operate at low speed.

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.)
