Safety (continued)
H For safe operation
We recommend that you frequently:
- Check for debris which could obstruct
the flow of flue gases. The vent or
chimney must not be blocked. A
blocked or partially blocked vent or
chimney can cause flue gases to leak
into the structure. Flue gases leaking
into the house can cause injury or
death. Blocked or partially blocked
chimneys must have the blockage
removed by a qualified heating
contractor.
- Check pressure gage for correct
system (water) pressure. Check for
water on the floor from the discharge
pipe of the pressure relief v al ve or any
other pipe, pipe joint, valve or air vent.
- Check for moisture, water, or
appearance of rust on the flue gas
pipes, their joints as well as vent
dampers, or side wall vent terminals (if
so equipped).
- Ensure that nothing is obstructing the
flow of combustion and ventilation air
and no chemicals, garbage, gasoline,
combustible materi als, flammable
vapors and liquids are stored (not even
temporarily) in the vicinity of the
boiler.
-Donot allow unsupervised childr en
near the boiler.
Service/inspection of the boiler and the
system is recommended once a year.
Maintenance, s ervice and cleaning are
specified in the Installation Instructions.
Before the heating season begins, the
boiler with its burners should be
serviced by a qualified heating
contractor. Service contracts may be

other licensed contractors in your area.
