similar pressure indicating device) to the pressure port at the inlet to the
burner. You will have to remove the 3/8” plug.
3. Open the supply valve to the burner supply regulator.
4. Turn the reigniter switch “ON”. Establish pilot by turning temperature control
dial to "RUN" position. Push down the "PILOT" button while igniting pilot
(hold button down for 30 - 60 seconds). After pilot flame is established,
rotate the temperature control dial counterclockwise. The main burner(s)

pressure port using a manometer (see No. 2 above). For the required burner
input pressure for each model refer to page 1-3. To adjust the pressure,
remove the cap on the burner supply regulator (See Figure 10) and turn the
adjustment screw clockwise with a standard screwdriver to increase the
pressure. Return burner supply regulator cap when complete.
6. Close the supply valve to the Burner Supply Regulator and wait until the
pilot and main burner have extinguished
. Turn the temperature control
dial to “OFF" position. Remove the manometer and fittings. Replace all
plugs and perform a leak test before proceeding .
