Utica Boilers SW Series II 安装指导

Venting system should be inspected at start of each heating 

season. 

• Check vent pipe from boiler to termination cap for 

signs of deterioration by rust or cracked silicone joints.  

Repair if necessary.

• Lever of safety relief valve, shown in Figure 17, on 

page 18, on boiler should be operated periodically to 

make sure it is functioning properly. Pressure relief 

valve should open before water pressure exceeds 

30 psi. reading on gauge. If pressure is exceeded 

and pressure relief valve leaks water when boiler is 

operating at normal pressures, immediately replace. 

Corrosion can build up rapidly at valve seat preventing 

it functioning as safety device. 

Start-up and adjustment of oil burner (See oil burner 

instructions for nozzle and electrode setting). 

A.  Check oil burner nozzle to make certain it is tight in 

adapter. Burner mounting bolts should be tight.

B.  Check electrode setting, as they may have been 

jarred out of position during transportation.

C.  Lubricate burner motor and circulator motor if 

required. Some circulators are water lubricated and 

do not require oiling.

D.  Set room thermostat to call for heat.
E.  Open all oil line valves.
F.  Turn service switch on. Burner should start.
G.  On one pipe fuel systems only, vent pump as soon 

as burner starts. Allow oil to run until all traces of 

air in the suction line disappear.

H.  Turn “OFF” burner and install pressure gauge in 

port on pump.

I.  Start burner again and check oil pressure for 140 

psi. Adjust if necessary.

Instruments are only reliable method to determine proper 

air adjustments. Improperly adjusted burner causes soot 

and high fuel bills because of incomplete combustion of fuel 

oil. This in turn may require excessive boiler maintenance, 

service costs. Consult competent service mechanic to make 

proper adjustments with smoke tester, CO

2

 indicator and 

draft gauge. Bacharach or Dwyer test kits include these 

instruments.

• 1/4" diameter slot is provided in inspection cover plate 

to take draft reading in combustion chamber.   

• 3/8" hole is provided in vent appliance adapter to take 

draft, CO

2

, smoke, and temperature readings. 

• Adjust air dial on oil burner to obtain trace of smoke. 

Measure CO

2

 at this point and increase air setting until 

CO

2

 = 1-1.5% lower than reading at trace point.  

• Check draft over fi re and in vent, normal readings will 

be positive (+.01 Over-fi re & +.02 In Vent) W.C.

Table page 17 is provided as guideline for initial start-

up. Final adjustments MUST be made using combustion 

instruments as previously mentioned.
