ventilation air to the boiler is not obstructed.
Inspection of Heat Exchanger Waterways
Appliances operated in hard water areas should have periodic
inspections of the tubes to be sure that no sediment or scale
accumulates on the heat transfer sur fac es. Inspection plugs are
located at both ends of the heat exchanger. In spec tion plugs
should be removed and tubes inspected at the end of the first 45
days of operation and again at the end of 90 days of operation.
If no scale accumulation is ob served, inspections can be made at
the end of each six months of op er a tion.
IMPORTANT
Upon completion of any testing on the
gas system, leak test all gas connections
with a soap solution while main burners
are operating. Im me di ate ly repair any
leak found in the gas train or re
lat ed
components. Do Not operate an
appliance with a leak in the gas train,
valves or related piping.
