FOR YOUR SAFETY READ BEFORE LIGHTING
WARNING: If you do not follow these instructions exactly, a fire or explosion may result causing property damage,
personal injury or loss of life.
1. This appliance does have an intermittant pilot. It is equipped with an ignition device which automatically lights the
pilot. Do Not try to light the pilot or burner by hand.
2. BEFORE OPERATING, 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.
3. WHAT TO DO IF YOU SMELL GAS
• Do not try to light any appliance.
• Do not touch any electrical switch; do not use any telephone in your building.
• Immediately call your gas supplier from a neighbor's telephone. Follow the gas supplier's instructions.
• If you cannot reach your gas supplier, call the fire department.
4. Use only your hand to push in or turn the gas control knob. Never use tools. If the knob will not turn by hand, do
not try to repair it, call a qualified service technician. Forced or attempted repair may result in a fire or explosion.
5. 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.
PRE-START-UP CHECK
1. Verify boiler is filled with water.
2. Check system piping for leaks. If found, repair immediately.
3. Vent air from system. Repeat steps 4 and 5 under “Fill the System.” Air in system can interfere with water
circulation and cause improper heat distribution.
