INSTALLATION & OPERATIONAL SSHLV SERIES MANUAL
WARNING
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 1.0 μA or greater, (0.15 μA or greater for CE units).
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 1.0 μA or greater, (0.15 μA or greater for CE units).
Note: Allow 3 to 5 minutes between flame adjustments to allow the reading to 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 manifold pressure tap plug and connect an accurate pressure gauge (range of
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.
