Crown Boiler AWR User's Information Manual page 4

• Do not store or use sources of hydrocarbons such as bleaches, fabric softeners, paints, cleaners,
refrigerants, and cat boxes near the boiler. Traces of these chemicals can be drawn into the boiler,
causing severe corrosion damage to the boiler and/or objectionable odors.
• Do not expose the boiler to large amounts of dust such as that generated by dry wall construction or
woodworking.
3) A qualified gas service technician should perform the maintenance procedure shown in the installation
manual on an annual basis.
4) The owner should visually inspect the venting system on a monthly basis. If any of the following condi-
tions are found, the boiler should be shut down and a qualified gas service technician called to correct the
problem before the boiler is placed back in service:
• Loose joints, corrosion or other deterioration
• Condensate leakage
• Sags in horizontal runs of vent pipe
The BWC has a heat exchanger made from a special aluminum alloy which can be severely damaged by frequent addi-
tions of water or by the addition of boiler water additives which are not designed for use with aluminum boilers. If it is
nessasary to add water to the boiler, have a service technican check the system for leaks. Do not add any chemicals to
the boiler not listed in the BWC installation manual. Warranty is void if the service and maintenance procedure shown
in the BWC installation manual is not followed.
Carbon ("soot") in or near the burner compartment area is an indication of a potential carbon monoxide hazard. If
carbon is found, the boiler should be shut down immediately and inspected by a qualified gas service technician. The
cause of the sooting should be found and corrected before the boiler is restarted.
5) The owner should also perform a monthly visual inspection of the boiler and the surrounding system
piping. To do this, remove the boiler jacket door. If any of the following are found, a qualified gas ser-
vice technician should be consulted immediately:
• Deterioration of the visible controls, wiring, and sheet metal components
• Heating system water Leaks
• Carbon ("soot") in or near the burner compartment area
• (BWC Boilers Only) - Make sure that the condensate drain system is unobstructed and leak-
tight.
6) BSI Series Boilers Only – Steam boilers require the following maintenance:
• Some steam boilers are equipped with a float type low water cut-off (Figure 3). This control
must be "blown down" on a weekly basis, or more often if needed. To do this, follow the
instructions on the label adjacent to the low water cut-off.
• It will occasionally be necessary to add water to the boiler. In most cases this will be true even
if the boiler is equipped with an automatic water feeder (most automatic water feeders maintain
the water level at the minimum point required to assure boiler operation). On a monthly basis,
turn the boiler off and wait at least 10 minutes for any water in the system to return to the boiler.
Add water to the boiler until the water level in the glass is approximately 6" (about 3/4 of the
way) from the bottom of the glass.
