All installations and services must be performed by qualified service personnel.

C. FURNACE CHECKOUT PROCEDURE

Before any system of gas piping is finally put into service, it shall be carefully tested to assure that it is gas tight as indicated in the manual.

NOTICE: All controls on the unit should be checked for proper functioning prior to the qualified service personnel leaving the job site. Specifically the following should be checked:

With furnace in normal heating operation, check to make certain blower will start and stop automatically under control of integrated fan control.

1.Check safety limit control as follows:

a.Shut off incoming power.

b.Disconnect blower motor leads.

c.Restore power to furnace.

d.Set thermostat above room temperature calling for heat.

e.When temperatures are reached in furnace at limit control setting with blower out of operation, burner should shut off.

f.Shut off electrical power.

IMPORTANT: Remove blockage or reconnect blower motor and restore power.

2.Make certain thermostat will automatically start and stop furnace.

3.Block the flue pipe gradually with a flat piece of metal, until the pressure switch functions shutting off the main burners. Note: If the burner was initially operating in high fire, the burner will first reduce rate to the low fire setting. As the flue becomes more blocked, the pressure switch will function and completely shut off the main burners.

4.Block the PVC pipe inlet gradually with a flat piece of metal until pressure switch functions shutting off the main burners. Note: If the burner was initially operating in high fire, the burner will first reduce rate to the low fire setting. As the flue becomes more blocked, the pressure switch will function and completely shut off the main burners.

IMPORTANT: Remove flue air inlet blockage when done.

5.Remove the blower compartment access door with the furnace operating. The door interrupt switch is in the 120 volt circuit and will shut down the entire system. Replace the blower door and the furnace start-up cycle will begin.

V. INSTALLER'S INSTRUCTIONS TO USER:

After completing the installation, the installer shall inform and/or demonstrate to the homeowner:

1.The location of all the instructions in the furnace and that these instructions and the users information manual must be kept along with instructions for any accessories in the plastic pouch on the inside of the furnace.

2.The location and use of the manual gas shut off valve and furnace electrical disconnect switch. Instruct user to always shut off gas before shutting off electric power.

3.The sequence of operation of the furnace.

4.The correct operation and maintenance of the appliance as outlined in the users information manual.
