NOTE
: Probe and float type low water cut-off devices require annual inspection and
maintenance. Refer to Service Instructions for proper cleaning instructions.
6.2.10 CHECK OPERATING CONTROL on Boiler equipped with tankless heaters. With
burner off, draw hot water until burner starts, then turn off hot water and check burner
shutdown.
6.2.11 CHECK OPERATING CONTROL OPERATION. Raise and lower operating control
setting as required to start and stop burner. With burner off, draw how water until burner
starts, then turn off hot water and check burner shutdown.
6.3 General Maintenance Considerations
6.3.1 Keep radiators and convectors clean.
6.3.2 If a hot water radiator is hot at the bottom but not at the top, it indicates that air
has accumulated inside and should be vented. To vent radiator, hold small cup under air
vent (located near top of radiator), open vent until water escapes and then close.
6.3.3 If mush water is added to system, it is advisable to heat system to high
temperature and vent again. This will make less venting necessary during the winter.
6.3.4 Where an expansion tank is used, makes sure that neither the tank nor its
drainpipe is exposed to freezing temperatures. Never place valves in piping leading to or
from expansion tank.
6.3.5 Boiler and system cleaning will help assure trouble free operation. See Item 5
and 6 Operating Instructions for procedure.
6.3.6 ATTENTION TO BOILER WHILE NOT IN OPERATION
NOTE: If Boiler is not used during winter time, it must be fully drained to prevent freeze
damage.
6.3.7 STEAM BOILERS – Procedure for taking steam Boilers off line at the end of
the heating season. Drain off boiler water until it runs clear while holding the boiler
temperature between 180 and 200 °F. Then refill to the top of the gauge glass.
6.3.8 WATER BOILERS – Procedure for taking water Boilers off line at the end of the
heating season. While the boiler temperature is still between 180 and 200 °F, drain
water from the bottom of the Boiler until it runs clear. Then refill the system to normal
water pressure.
NOTE: Any time raw water is introduced into the Boiler, it must be immediately heated
to 180 °F to drive off dissolved gases. If water treatment is used, sufficient water
treatment compound should be added to condition to make up water.
