To determine if the air shutter needs adjustment, it is necessary to view the flame pattern with the variable output control knob at its highest setting. Allow the unit to operate for 10 minutes to allow the entire unit to reach temperature and for the flame pattern to stabilize. Generally, the more air (open shutter) in the mixture, the bluer the flame. Less air (closed shutter) results in a more yellow flame, but too little air will result in incomplete combustion, low efficiency and a dirty burn. There are two simple guidelines to aid in determining the correct flame pattern:
1.if the flame at the base of the logs is completely blue, the air shutter may be open too far;
2.if the flame is dirty or licks the top of the stove, the air shutter may be closed too far.
Some conditions cannot be corrected
through air shutter adjustment; an adjustment must be made to the gas supply pressure or by changing the restriction plate location. Qualified service personnel must perform supply line/manifold gas line pressure adjustments and restrictor plate adjustments Do not attempt to complete any part of the installation or adjustment of this unit unless technically qualified to do so.
LIGHTING INSTRUCTIONS
NOTE: The gas control knobs and the piezo ignitor are located behind the control valve access door, under the front of the unit.
1.STOP! Read the What To Do If You Smell Gas! Warning (on the cover of this manual).
2.Set the on/off/T’stat switch or thermostat
to the “OFF” position.
3.Unplug the fan accessory, if so equipped.
4.Push in and turn gas control knob clockwise to “OFF”. (If not previously lit, the knob should be in this position.)
5.Wait (5) five minutes to clear out any gas. If you then smell gas, STOP! Smell all around the appliance area for gas. Be sure to smell next to the floor because some gases are heavier than air and will settle on the floor. If you smell gas immediately follow the What To Do If You Smell Gas! warning on the cover of this Manual. If you do not smell gas, proceed to the next step.
6.Turn gas control knob
7.Push in control knob all the way and hold in. Immediately light the pilot with the gas lighter (push in and “click” the piezoelectric spark ignitor button several times until lit). Continue to hold the control knob in for about 20 seconds after the pilot is lit. Release the knob and it will pop back out. Pilot should remain lit. If the pilot goes out, repeat the operation.
∙If knob does not pop out when released, stop, shut off the gas supply to the heater and immediately call a qualified service technician or gas supplier.
∙If the pilot will not stay lit after several tries, turn the gas control knob “OFF” and call a qualified service technician or gas supplier.
8.After the pilot lights, turn gas control knob
9.If the ON/OFF/T’stat switch is set to “ON”, the stove should now be lit. If the thermostat (or remote) has been installed, set the ON/OFF/ T’stat switch to “T’stat” and turn the thermostat (or remote) to “ON”. Then set the desired temperature.
