CSD-1 Control System – Propane gas
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”).
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.
