17.4 SYSTEM PIPING INSPECTION
Inspect all piping (water and gas) on the boiler system for leaks and verify that the piping is leak
free and properly supported. Inspect the fittings and components on the unit and verify they are
leak free.
WARNING!
Eliminate all boiler water system leaks. Continual fresh make-up
water will reduce the heat exchanger life causing boiler failure.
Leaking water may also cause severe property damage to the
surrounding area. Inspect the gas supply piping using the
procedure outlined in section 12.3.3.
17.5 CLEAN CONDENSATE DRAIN ASSEMBLY
Cleaning the Condensate Drain Assembly
1. Loosen the retaining nut from the condensate drain assembly and disconnect the assembly
from the boiler.
2. Empty any water from the trap and drain assembly. Flush with fresh water as necessary to
clean.
3. Check the drain piping from the condensate drain assembly to the drain. Flush to clean as
necessary.
4. Reassemble the condensate drain assembly onto the boiler by tightening the retaining nut
with rubber seal onto the boiler. Hand tighten only.
5. Remove the fill plug on the condensate drain assembly and fill with water. See Figure 6-1.
6. Replace the fill plug on drain assembly.
17.6 VENTILATION AIR OPENINGS INSPECTION
•
Verify that all ventilation openings to the mechanical room or building are open and
unobstructed. Check the operation and wiring of any automatic ventilation dampers.
•
Check and verify the vent discharge and the combustion air intake are free of debris and
obstructions.
17.7 VENT AND COMBUSTION AIR PIPING INSPECTION
•
Visually inspect the venting system and combustion air piping for blockage, deterioration
or leakage. Repair any deficiencies.
•
Verify that the combustion air inlet piping is connected, sealed and properly supported.
WARNING!
Failure to inspect the vent system and combustion air inlet piping
and to have any conditions repaired can result in severe personal
injury or death.
