OPERATING INSTRUCTIONS

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.

This appliance has a pilot which can  be light with the equipped piezo ignitor.  When lighting the pilot, follow these
instructions exactly.

BEFORE LIGHTING 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 attempt 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.

Use only your hand to push in or turn the gas control knob. Never use tools. If the knob will not push in or 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.

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.

Press the knob lightly and turn clockwise                to the “OFF” position.

Wait five (5) minutes to clear out any gas.  If you then smell gas, STOP!  Follow

Press the knob down lightly and turn counterclockwise              to the “Pilot”.
Press again downwards.

Press the Piezo Ignition button to light the pilot.  Repeat this operation with the
knob pressed down until the pilot has lit.  When the pilot lights, continue holding
pressure for another 10 seconds.  Release the knob.  If the pilot goes out, repeat
the process 1 through 6.

If the knob does not pop up when released, stop and immediately call your ser-
vice technician or gas supplier.

If the pilot will not stay lit after several tries, turn the gas control knob to OFF and
call your service technician or gas supplier.

Press down and turning the control knob counterclockwise                to the

LIGHTING INSTRUCTIONS

When the heater is first started after installation or if the heater has not been used for a long period of time, there is a
normal delay of gas from the gas supply through the gas control on the heater.  In this case, maintain pressure on the knob
at the “Pilot” position for 30-40 seconds and then try the piezo lighter.

When the heater is not to be in use for a long period of time or for servicing, turn the control knob clockwise                 to
the OFF position and close the main gas supply valve.
