Pilot Flame Adjustment; Main Burner System Adjustment - Pitco SSHLV184 Series Installation & Operation Manual

INSTALLATION & OPERATIONAL SSHLV SERIES MANUAL
Do not store flammable materials in or near this appliance. Do not spray aerosols in the
vicinity of this appliance while it is in operation. Contact a qualified service person or the
factory, using the information on the back of this manual, if the appliance produces unusual
odor, yellow tipping flames or is not performing as per the original installation.

2.11.3. PILOT FLAME ADJUSTMENT

Perform this procedure with the pilot lit.
Note: This procedure requires the use of a DC microammeter.
1. Connect the DC microammeter between the flame sensor terminal and the flame
sensor lead. Observe proper polarity: if the meter needle goes below 0, reverse
the leads. The current reading must be or 0.15 µA or greater.
2. Adjust the current reading to the required level by adjusting the pilot flame.
Remove the pilot adjustment screw cap to expose the pilot adjustment screw.
Turning the pilot adjustment screw clockwise will decrease the size of the pilot
flame and flame sense current. Turning the pilot adjustment screw
counterclockwise will increase the pilot flame size and the flame sense current.
3. Rotate the screw in the direction needed to achieve a reading of 0.15 µA or
greater.
Note: Allow 3 to 5 minutes between flame adjustments to allow the reading
stabilize.
4. Once the pilot flame has been adjusted properly, replace the pilot adjustment
screw cap screw and remove the microammeter.

2.11.4. MAIN BURNER SYSTEM ADJUSTMENT

For the main burners to operate the gas supply valve must be open and the
main power button on the computer must be pressed. The main burners
receive gas from the main gas supply through the thermostatically controlled
valve. When the oil temperature drops below the preset temperature the
gas control valve opens.
The main burners must be adjusted to deliver optimum flame. Refer to the following procedure to
adjust the main burners.
1. Ensure that the main gas valve is shut off, remove the burner pressure tap plug and connect
an accurate pressure gauge (range of 0-16 "W.C. (39.85mbar, 3.98kPa) in 0.1" (.25mbar,
.02kPa) increments) or manometer.
2. Turn on this and all appliances connected to the gas supply line and light their main burners.
The pressure reading of the installed pressure gauge should not drop from the required
installation pressure. Any loss of pressure indicates inadequate supply line installation, which
will cause poor performance of all appliances during peak usage.
3. The installed pressure gauge should be the same, ±0.1" W.C. (.25mbar, .02kPa), as that
marked on the data plate on the inside door of the appliance. If the pressure is correct, go to
step 6, if it is not, adjust the pressure as outlined in step 4.
4. To adjust the pressure, remove the burner pressure adjustment screw cap and, with a flat
head screwdriver, adjust the regulator screw until the proper burner pressure is reached.
Turning the screw clockwise will increase the burner pressure. Turning the screw
counterclockwise will decrease the burner pressure. When the pressure is correct, replace
the regulator adjustment screw cover.
