INSTALLATION

Continued

8.Recheck all air vents as described in step 4.

9.Inspect the liquid level in the expansion tank. The system must be full and under normal operating pressure to ensure proper water level in the expansion tank. Ensure that diaphragm type expansion tanks are properly charged and not water logged.

10.Start the boiler according to the operating instructions in this manual. Operate the system, including the pump, boiler and radiation units, for one hour.

11.Recheck the water level in the expansion tank. If it exceeds half the tank volume, open the tank to reduce the water level. Recheck pressure charge on diaphragm type tanks.

12.Shut down the entire system and vent all radiation units and high points in the system.

13.Close the water makeup valve and check the strainer and pressure reducing valve for sediment or debris. Reopen the water makeup valve.

14.Verify system pressure with the boiler pressure gauge before beginning regular operation.

15.Within three days of startup, recheck and bleed all air vents and the expansion tank using these instructions.

WATER TREATMENT

In hard water areas, water treatment should be used to reduce the introduction of minerals to the system. Minerals in the water can collect in the heat exchanger tubes and cause noise on operation. Excessive build up of minerals in the heat exchanger can cause a non-warrantable failure.

OPERATION

FOR YOUR SAFETY READ BEFORE OPERATING

￿WARNING: If you do not follow these instructions exactly, a fire or explosion may result causing property damage, personal injury or loss of life.

A.This appliance does not have a pilot. It is equipped with an ignition device which automatically lights the burner. Do not try to light the burner by hand.

B.BEFORE OPERATING, smell around the appliance area for gas. Be sure to smell next to the floor because some gas is heavier than air and will settle to the floor.

WHAT TO DO IF YOU SMELL GAS

• Do not try to light any appliance.

• Do not touch any electric switch; do not use any phone in your building.

• Immediately call your gas supplier from a neighbors phone.

• Follow the gas supplier's instructions.

• If you cannot reach your gas supplier, call the fire department.

C.Use only your hand to turn the gas control lever. Never use tools. If the lever will not turn by hand, don't try to repair it, call a qualified service technician. Force or attempted repair may result in a fire or explosion.

D.Do not use this boiler if any part has been under water. Immediately call a qualified service technician to replace the boiler. The possible damage to a flooded boiler can be extensive and present numerous safety hazards. Any appliance that has been under water must be replaced.

Lighting Instructions

1.STOP! Read the safety information.

2.Set the temperature control to the desired settings (see Setting Temperature Control, page 29).

3.Loosen the knurled knob at the bottom of the control panel cover (see Figure 31).

4.Grasp the bottom of the control panel cover and pull out and down.

5.Locate the ON/OFF switch inside the control area. The switch is located to the left of the control panel (see Figure 32).

6.Turn the power switch to the “OFF” position.

7.This unit is equipped with an ignition device which automatically lights the burners. Do not try to light the burners by hand.
