  4.  Turn gas control knob clockwise 

 to the OFF position, set the thermostat to the lowest setting and 

turn ON/OFF switch to OFF position.

  5.  Wait (5) minutes to clear out any gas. Then smell for gas, including near the floor. If you smell gas, STOP! 

Follow the instructions under “What To Do If You Smell Gas,” page 29.

NOTE: If you are running the heater for the first time, it may be 

necessary to press in the control knob for 30 seconds or longer to allow air to bleed out 
of the gas piping. 

  7.  With the control knob pushed in, push in and release the piezo ignitor button to light the pilot.
  8.  Continue pushing the control knob in for a further 10 seconds to prevent the flame detector from shutting 

off the gas while the probe is warming up. Release the control knob.

 to the ON position.

 10.  After the pilot has been lit for one minute, the burners can be turned on. Turn the ON/OFF switch to 

ON position or adjust thermostat to desired setting. 

NOTE: To use the thermostat  function (if 

installed) the control knob must be set to “ON” and ON/OFF switch must be in the “OFF” 
position.
