VII Operating instructions

Starting

boiler

A.This boiler is equipped with a pilot which must be lighted by hand. When lighting the pilot, follow these instructions exactly. The gas supply to this pilot is controlled by Pilot switch box. This boiler is also equipped with an ignition device which automatically lights a second pilot. The gas supply to this pilot is controlled by the Gas control. Do not try to light this pilot by hand.

B.BEFORE OPERATING THE MANUAL PILOT, smell all around the appliance area for gas. Be sure to smell next to the floor because some gas is heavier than air and will settle on 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 neighbor’s phone. Follow the gas supplier’s instructions.

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

C.Do not use this appliance if any part has been under water. Immediately call a qualified service technician to inspect the appliance and to replace any part of the control system and any gas control, which has been under water.

This document is intended only as a supplement to the LGB Gas-Fired Boiler Manual. Follow all instructions in the Manual, including those regarding start-up (found in Section VIII, “Placing boiler in operation”).

1. STOP! Read the safety information above.

2. Set the Operating control to lowest setting.

3. Turn off all electrical power to the appliance.

4.Remove the Base access shield.

5.Close the Pilot shut-off valve connected to Manual main shut-off valve. Close Manual main shut-off valve.

6.Wait five (5) minutes to clear out any gas. Then smell for gas, including near the floor. If you smell gas, STOP! Follow“B”in the safety information above. If you don’t smell gas, go to the next step.

7.Open the Pilot shut-off valve.

8.Press and hold the reset lever on the Pilot switch box. Manually light the

pilot while holding the lever down. Air in the gas supply line will have to purge through the line before sufficient gas will reach the pilot.

9. After purging all air, hold the Pilot switch box lever for about 1 minute to heat the thermocouple.

10.Release the Pilot switch box lever. The pilot should remain lit.

11.Open the Manual main shut-off valve and follow the sequence below.

12.This appliance is also equipped with an ignition device which automatically lights the second pilot. Do not try to light this pilot by hand.

13.Turn on all electric power to the appliance.

14.Set Operating control to desired setting.

15.If the appliance will not operate, turn off gas to the appliance by closing the Manual main shut-off valve and Pilot shut-off valve. Call your service technician or gas supplier.

16.Replace Base access shield and Front panel.
