DRAFT FAN AND AIR DAMPER CLEANING (continued)
The primary air damper (flapper) in front of the draft fan MUST swing open and closed freely
and easily. The draft fan should open the primary air damper and the counterbalance should
close the damper when the fan turns off. If the damper sticks in either position, operation will
be adversely affected. Lubricate the damper with a light graphite oil. Check the damper once
or twice a month! Overheating of the boiler can occur if the damper sticks open!
LOW WATER CUTOFF MAINTENANCE
Periodically inspect any low water cutoffs and flush if they are of float types.
OIL AND GAS BURNER MAINTENANCE
Refer to the burner manual provided with the burner for maintenance instructions.
The burner must be serviced by a qualified burner technician.
LOADING DOOR
The primary air inlets are located at the top corners of the boiler loading door opening. Any
creosote buildup in these openings must be removed. The doorframe and openings should be
cleaned frequently to remove any creosote buildup.
Check the loading door and ash door gaskets regularly to insure that they are sealing well and
that there is no smoke spillage into the house or unwanted air leakage into the boiler.
CLEANING THE PRIMARY AIR DUCTS
The primary air ducts on each side of the loading door can very rarely get clogged with
creosote due to a reversed chimney draft or improper firing. Although this should not happen, if
it does, the boiler will start to perform poorly and it will be necessary to clean the primary air
ducts. To clean the air ducts, the load and ash doors, along with the front jacket panel, will
need to be removed. Then remove the panel cover between the upper and lower door
openings. You now have access to clean the primary air ducts. Make sure you don’t let debris
block the secondary air ducts. After cleaning reposition the secondary air damper and access
panel. Apply silicone to reseal the access panel. Re-install the jacket panel and doors as done
during the original installation.
SMOKE PIPE CLEANING AND INSPECTION
Annually disassemble the stovepipe. Clean and inspect for corrosion. If any pipe is seriously
corroded (for example, if a screwdriver can easily be poked through the metal), this section
must be replaced.
CHECK FOR CREOSOTE BUILDUP
Check for creosote buildup in the heat exchange tubes, the smoke pipe and the chimney once
a month. If you see a buildup of creosote, something is wrong.
NOTE: Creosote buildup, other than in the primary combustion chamber, is generally a
sign that there is air leakage into the boiler during the off cycle which is resulting
in a low-grade fire. Check your door gaskets and the primary air damper near the
draft fan.
