Checking Burner & Controls; Lubrication; General Maintenance Considerations; Attention To Boiler While Not In Operation - Burnham V11 Series Installation, Operating And Service Instructions

all visible wiring for brittle or worn insulation and
make sure electrical contacts are clean and that they
function properly. Give special attention to solder
joints on bellows and float when this type of control
is used. Check float for evidence of collapse and
check mercury bulb (where applicable) for mercury
separation or discoloration. DO NOT ATTEMPT
TO REPAIR MECHANISMS IN THE FIELD.
Complete replacement mechanisms, including
necessary gaskets and installation instructions, are
available from the manufacturer.
D
. CHECK BURNER AND CONTROLS at least once
a year. See Section IV, Paragraph (E) under Operating
Instructions for control checks. See Burner Manual for
burner tests and adjustments.
E.
LUBRICATE BOILER COMPONENTS
according to manufacturer's instructions. Generally,
this involves the oil burner and circulator. This includes
the type of lubricant to use, frequency of lubrication,
and points to lubricate.
F.
GENERAL MAINTENANCE
CONSIDERATIONS
1. Keep radiators and convectors clean.
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.
3. If much water is added to system, it is advisable to
heat system to a high temperature and vent again.
This will make less venting necessary during the
winter.
4. Where an expansion tank is used, make sure that
neither the tank nor its drain pipe is exposed to
freezing temperatures. Never place valves in piping
leading to or from expansion tank.
5. Boiler and system cleaning will help assure trouble
free operation. See Section IV, Paragraphs (F and
G) under Operating Instructions for procedure.
G.
ATTENTION TO BOILER WHILE NOT IN
OPERATION
If boiler is not used during winter time, it must be
fully drained to prevent freeze damage.
1. Spray inside surfaces with light lubricating or
crankcase oil using gun with extended stem so as to
reach all corners.
2. With steam boilers, at end of season add sufficient
water to fill boiler to top of water column and leave
it that way until fall when water should be drained
again to proper level. If at this time boiler water is
dirty, drain water, flush out boiler, and refill with
clean water to prescribed water level.
3. Always keep the manual fuel supply valve shut off
if the burner is shut down for an extended period of
time.
4. To recondition the heating system in the fall season
after a prolonged shut down, follow the instructions
outlined in Section IV - Operating Instructions,
Paragraphs (B) through (E).
