The setting of the fan output according to the installation should be done only through the air damper. Should you want to adjust the setting of the combustion head, with the burner running, turn the rod (1) with a 6mm wrench (2) as follows: TURN TO THE RIGHT: (SIGN + ) In order to increase the volume of air entering the combustion chamber and thus diminishing its pressure. There is a reduction of CO and the adhesion of Figure 21 2 the flame to the air diffuser disc improves.

ii. CARBON DIOXIDE (CO ) OR OXYGEN (O ): Take a CO sample from flue passageway. It is possible to 2 2 2 achieve readings of up to 14% CO (or 2% O ), but it is better to have a slightly lower CO (or higher O ) 2 2 2 2 reading with zero smoke measured. To achieve a lower CO reading, open the air band, or shutter, on the 2 burner until zero smoke is measured. For example, if a 13% CO (or 3.5% O ) is recorded at a trace of smoke, open the air shutter until zero smoke is 2 2 measured with a 12

a. With the oil shut off, remove the 1/8 in. NPT threaded pipe plug located on the lower rear side of the oil pump, refer to Figure 22. Attach a pressure gage, capable of measuring pressure in pounds per square inch gage, PSIG, in this opening, on the discharge side, of the oil pump. NOTICE: It may be necessary to remove the oil pump to attach the plumbing required to connect a pressure gage to the pump. b. Turn on the fuel oil and cause the appliance to activate the heat
