INSPECTION AND SERVICE
1Align burner combustion head (A) into the boiler housing tube with gasket (B) correctly fitted.
Push firmly down to compress the gasket (B). Tighten burner retainers (C) sufficiently to ensure a good seal.
IMPORTANT:
Ensure the gasket is a good seal between the burner combustion head and the boiler housing to prevent flue gases escaping.
Refit flexible air duct and secure with clip (D).
2Plug burner lead (E) into control box (F). Connect an oil pressure gauge to the oil pump, run the burner and check the oil pressure is correct for the required boiler output. Check that the smoke reading is between 0 and 1, if the smoke reading is above 1 check the air setting. If the air setting is correct check that the burner has been reassembled correctly.
Allow the boiler to warm up then check the combustion settings are correct as indicated in the table below, adjust the
CO2 if necessary using the air shutter. When the combustion is correct turn off the boiler, remove the pressure gauge and refit the blanking plug and plastic cover.
