B. Primary control and flame sensor:
Check:
1.
flame failure
- simulate by shutting off oil supply with
hand valve while burner is on. Sixty seconds after flame-
out, the safety switch locks out, ignition stops, motor
stops and oil valve - when used - closes. To restart, open
oil supply valve and reset safety switch.
2.
Ignition failure
- with burner off, close oil supply valve
and run through start-up procedure, The safety switch
should lock out as in flame failure.
3.
Power failure
- Turn off main power supply switch while
burner is operating. When burner stops, restore power
and burner should start.
If operation is not as described as above, check wiring and
controls.
PREVENTIVE MAINTENANCE
of an oil fired boiler
reduces operating costs. The boiler and vent pipe should
be inspected for accumulation of soot or scale deposits
periodically but at least once every year before the start
of each heating season. When soot is present on the sec-
tion walls and flueways, improper combustion will result,
causing additional sooting and scaling until flueways are
completely closed. To remove soot and scale from the flu-
eways, remove top jacket panel, top clean-out plate, open
burner swing door. (See
figure #19
)
PERIODIC INSPECTION
and tightening of the tankless
heater/cover plate bolts will reduce the risk of leaks. See
part number 6,
replacement Parts “Heat Exchanger”
section
in the back of this manual.
