14 Install burner
To install burner:
1.Unpack burner.
2.Place gasket around air tube and against burner mounting flange. If sealing rope is used, apply 1/8" continuous bead of rope adhesive around burner mounting flange and apply sealing rope to make
3.Mount burner into opening in burner mounting plate.
Maintain
4.Level burner using burner support brackets where required.
5.Secure with furnished bolts.
6.Retain burner information packet. Keep with boiler.
15 Wiring and fuel piping
Electric shock hazard. Can cause severe personal injury or death if power source is not disconnected before installing or servicing boiler and burner.
To wire burner and boiler controls:
1.Install all wiring in compliance with:
•National Electrical Code ANSI/NFPA 70.
•Any additional national, state, or local codes.
2.Follow burner manual and wiring diagram found in burner information packet.
3.Use 14 ga. wire for operating and safety circuit wiring.
4.Where burner motor voltage differs from control voltage, supply proper voltage to each. Size fused disconnect(s) and conductors per National Electrical Code ANSI/NFPA 70.
To install gas and/or oil piping:
1.Install all piping in compliance with:
•Local, state or national codes and regulations.
•Seperate burner manual provided with burner.
2.Use pipe joint compound (pipe dope) resistant to corrosive action of fuel oil or liquified petroleum gases. Apply sparingly to male threads of pipe joints. Do not use any kind of pipe tape.
3.Oil piping – use
Do not use compression or soldered fittings. No safe repair can be made. Severe personal injury, death or substantial property damage will result.

16 Make final adjustments
To fill water boilers:
1.Close manual air vents and drain cocks.
2.Fill to correct system pressure. Correct pressure will vary with each installation.
3.Starting on lowest floor, open air vents one at a time until water squirts out. Close vent. Repeat with remaining vents.
4.Refill boiler to correct pressure.
To fill steam boilers:
1.Do not fill (except for leakage test) until boiler is ready to be fired.
2.Fill to normal waterline, halfway up gauge glass.
3.Recommend boiler water pH 7.0 to 8.5.
Adjust burner and damper assembly:
1. Lock open flue transition damper.
Make final burner adjustments using combustion test equipment to assure proper operation. Do not fire boiler without water. Sections will overheat, damaging boiler and resulting in severe property damage.
2.Refer to burner manual for
3.Let burner advance to high fire. Heat boiler to design conditions.
4.Using combustion test equipment, adjust burner for:
a.12% (± ¼%) CO2 for No. 2 fuel oil, 0 smoke.
b.9 – 10% CO2 natural gas; CO in flue gas not to exceed 50 ppm (0.01%).
5.Adjust damper assembly (Figure 35, page 33) to ensure 0.1" W.C. positive pressure at test opening. Tighten screws to secure in position. Plug test opening with 3/8" bolt provided with damper assembly.
6.Adjust barometric draft control, when used, to design conditions.
7.Repeat steps 4 through 6. Adjust as required.
