Sequence Of Operation
On call for heat, thermostat will actuate, completing the
circuit to the boiler. In turn, the ignition systems are
activated and ignition will begin.
In event of a low water condition, an automatic low water
cut-off device will interrupt power between the low water
cut-off and burner. Burner remains off until low water
condition is corrected, (i.e., manually restore boiler water
or utilize water feeder device which automatically restores
water to its normal operating level).
Installer
- Before putting boiler in operation, test
mechanical low water cut-off device for proper operation.
While burner is on, open blow-off valve located in lower
portion of cut-off body. This will drain water quickly from
cut-off body and break circuit to burner. If it does not,
replace control.
DANGER
Water temperatures exceeding 125°F will cause
severe burns instantly or death by scalding.
!
Refill boiler to its normal water line.
Operating Instructions
• Start of heating season have venting system inspected.
Check vent pipe from boiler to chimney for signs
of deterioration by rust or sagging joints. Repair if
necessary.
• Remove vent pipe at base of chimney or flue and, using
mirror, check for obstruction and verify compliance to
latest revision of the NFPA 211.
• Operate lever of safety valve on boiler periodically to
verify it is functioning properly.
See
Figure #14.
• Safety relief valve should open before steam pressure
exceeds 15 psi. reading on the gauge. If this pressure
is exceeded and safety relief valve leaks steam when
boiler is operating at normal pressures, immediately
replace. Corrosion can build up rapidly at valve seat
and prevent its functioning as a safety device.
