LIGHTING INSTRUCTIONS

1.  Set thermostat to the lowest setting (PILOT LIGHTING).

TO TURN OFF GAS TO APPLIANCE

BEFORE OPERATING: ENTIRE SYSTEM MUST BE FILLED WITH WATER AND AIR PURGED FROM ALL LINES

.

1.    

STOP!   Read the safety information 

     

above on this label.

2.   Set the thermostat to lowest setting (PILOT LIGHTING). 

Turn thermostat dial fully clockwise  

  until it stops.

3.   Push the gas control knob down slightly and turn 

clockwise 

  to “OFF”, see Figure “A”..

   

NOTE:

 Knob CANNOT be turned from “PILOT” to “OFF” 

unless it is pushed down slightly.  Do not force.

4.   Remove the outer burner door located below the gas 

control.

5.   Wait fi ve (5) minutes to clear out any gas.  If you then smell 

gas, 

 STOP!  Follow “B” in the safety information above 

on  this label. If you don’t smell gas, go to next step.

6.   This unit is equipped with a push button pilot ignitor, 

which is used to light the pilot. Locate the ignitor on the 
gas control.

7.   Turn gas control knob counterclockwise 

  to “PILOT”, 

see Figure “B”.

8.   The pilot is located on the right side of the burner. It can 

be located by looking through the glass view port while 
pressing the piezo ignitor button several times. Look for 
a spark at the pilot location, see Figure “D”.

9.   Once the pilot has been found, push the gas knob all 

the way down.  Immediately press the pilot ignitor button 
rapidly (4) to (5) times. If the pilot will not light, repeat step 
(3) through (9).

10.  Continue to hold the gas control knob down for about one 

(1) minute after the pilot is lit. Release the gas control 
knob and it will pop back up. Pilot should remain lit. If it 
goes out, repeat step (3) through (9). It may take several 
minutes for air to clear the lines before the pilot will light.
•  If knob does not pop up when released, stop and 

immediately call your service technician or gas supplier.

•  If the pilot will not stay lit after several tries, turn the 

gas control knob clockwise 

 to “OFF” and call your 

service technician or gas supplier, see Figure “A”.

  to “ON”, see Figure “C”.

13.  Set thermostat to desired setting.

 

 

DANGER: Hotter water increases the risk  of  

 

scald injury.  Consult the instruction manual  

 

before changing temperature.

A.  This appliance has a pilot which is lit by a piezo-electric 

spark gas ignition system. Do not open the inner door 
of the appliance and try to light the pilot by hand.

 
B. 

BEFORE LIGHTING

 smell all around the appliance 

area for gas. Be sure to smell next to the fl oor because 
some gas is heavier than air and will settle on the fl oor.

WHAT TO DO IF YOU SMELL GAS:

•  Do not try 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
