Operating Instructions - UTICA BOILERS SFH-3085 Installation, Operation & Maintenance Manual

Operating Instructions

1.
Inspect venting system at start of each heating season.
2.
Check vent pipe from boiler to chimney for signs
of deterioration by rust or sagging joints. Repair if
necessary.
3.
Remove vent pipe at base of chimney or flue and, using
mirror, check for obstruction.
Safety Relief Valve
!
WARNING
Burn and scald hazard. Safety relief valve could
discharge steam or hot water during operation.
• Operate lever of safety relief valve, on boiler
periodically to make sure it is functioning properly.
• Safety relief valve should open before water pressure
exceeds 30 psi reading on gauge.
• If this pressure is exceeded and safety relief valve
starts leaking water when boiler is operating at normal
pressures, it should be immediately replaced.
• Corrosion can build up rapidly at valve seat and
prevent its functioning as safety device. See Figure
#11, page 13.
Start-Up And Adjustment Of Oil Burner
(See oil burner instructions for nozzle and electrode
setting)
A. Check oil burner nozzle to verify it is tight in the
adapter.
B. Check electrode setting, may have been jarred out
of position during transportation.
C. Burner mounting bolts should be tight.
D. Set room thermostat to call for heat, or jump
thermostat contacts on the boiler control.
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 port
on pump.
I. Start burner again and check oil pressure per setup
charts on page 24. Adjust if necessary.
OPERATING INSTRUCTIONS
Do not set fire visually. 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,
and in some instances, house cleaning or redecorating. A
competent service mechanic should be consulted to make
proper adjustments with smoke tester, CO
draft gauge.
Instructions For Proper Operation Of Boiler
Burner Unit
A ¼" diameter slot is provided in inspection cover plate to
take draft readings in combustion chamber. See Figure
#26. A ¼" diameter hole will be required in flue pipe
between boiler and barometric damper (if used) to take
draft, CO
shutter on oil burner to obtain "trace" of smoke. Measure
CO at this point. Increase air adjustment to lower CO

approximately one (1) percent. Check to insure minimum
negative .02" w.c., (water column), "overfire" draft and
zero (0) smoke. If - .02"w.c. "overfire" draft can not be
maintained, changes and/or modifications may be required
in venting or chimney.
Following tables (page 25) are provided as guideline for
initial start-up. Final adjustments MUST be made using
combustion instruments as previously mentioned.
Check Safety Control Circuit - for satisfactory
performance after burner adjustments have been made.
1. High limit control: remove cover and note temperature
setting. See Figure #26. With burner operating,
decrease setting to minimum point. When boiler water
temperature exceeds this set point, high limit switch
will open, shutting off power to oil burner. Return
setting to desired high limit point. Burner should
restart. Refer to instructions included with limit.
2.
Primary control and flame sensor check following:
A. Flame failure - simulate by shutting off oil supply
B. Ignition failure - with burner off, close oil supply
C. Power failure - Turn off main power supply switch
If operation is not as described as above, check
wiring and controls.
