LIGHTING AND OPERATION (ALL MODELS)
STEP ONE: PILOT LIGHTING (ALL MODELS)
1. Slightly push in the “EASY” Safety Valve Knob, located behind the ALTERNA™ face plate on the right side (Figure
32A), and turn clockwise to “OFF”.
2. Before lighting, wait at least five minutes to allow gas which may have accumulated around burner to escape, then
slightly push in the “EASY” Safety Valve Knob and turn to “PILOT/OFF”.
3. Depress Valve Knob until air dissipates and gas flows to pilot (located at center of ATERNA™). Press the Piezo
Igniter Button (left side of ALTERNA™) (Figure 33) to light the pilot, and continue to hold Valve Knob in until pilot
remains lighted after knob is released. The pilot flame should be steady and soft blue surrounding 1/8 inch of the ther-
mocouple tip and extending approximately 1 inch beyond the pilot tube as shown in Figures 34 A and B below.
NOTE: If pilot flame adjustment is necessary, use a narrow long stem flathead screwdriver to turn Pilot Adjustment
Screw clockwise for less flame, counterclockwise for more (Figure 32B). If after pilot adjustment the burner begins to
shutdown, re-adjust for a longer pilot flame.
4. Slowly turn Valve Knob to “ON” to light burner. (If burner fails to light or if pilot goes out, repeat steps 1 through 4.
5. Adjust the burner flame height by turning the “EASY” Safety Valve Knob clockwise to lower and counter-clockwise to
raise up to full on (Figure 32).
6.For complete shutdown, push “EASY” Safety Valve in and turn to “OFF”.

NOTE: The “EASY” Safety Valve has complete control of gas to the pilot and burner. It cannot be turned to “OFF”
without first depressing knob to the “PILOT” position and then rotating clockwise to “OFF”. During the heating season
leave valve knob in “PILOT” position for convenience. Otherwise, turn to “OFF” position for any prolonged non-use.
Periodically check the pilot and burner flame for proper appearance (see page 23 “Customer Responsibilities and
Maintenance”).
