C. Inspect Pressure Relief Valve (Monthly)
1. Inspect the pressure relief valve outlet for signs of leakage.
2. Notify a qualified service contractor immediately if there are signs of leakage. (If the problem
persists, it may be the result of a malfunctioning expansion tank or improper system design).
D. Inspect Condensate Drain System (Monthly)
1. Check the vent hole on the top tee outlet of the condensate drain pipe. Make sure there are no
exhaust emissions leaking from this hole.
2. Check the condensate drain piping for visible water leaks.
3. Check the level of condensate neutralization media (where used) in the front condensate
collector.
4. Notify a qualified service contractor immediately if there are signs of leakage or depleted
neutralization media.
E. Observe Boiler Operation (Monthly)
1. Initiate a call for heat from the system by turning up a room thermostat or draining hot water at
a faucet (if an indirect water heater is used).
2. Observe the boiler start and listen for objectionable noises during the start-up.
3. Contact a qualified service person if objectionable sounds are observed.
F. Control Inspection and Maintenance (As Required by Control Manufacturer)
1. Safety Relief Valve. Conduct try lever test as outlined in manufacturer’s instruction tag on the
safety relief valve.
2. Low Water Cut-off (if used). Follow instructions provided by control manufacturer.
G. General Inspection and Maintenance (Annual)
Annual inspection and service is to be performed by a qualified service contractor as specified in the
Installation, Operation and Maintenance Manual supplied to the installer with the boiler. If a copy of the
original Installation, Operation and Maintenance Manual is not available a new copy is available at
PeerlessBoilers.com or from your local PB Heat Representative.
WARNING
Do not operate the boiler with the condensate drain line disconnected. If there is evidence of
exhaust leakage from the condensate drain line, turn off the unit and contact a qualified service
contractor. These conditions may result in boiler exhaust entering the structure and causing
severe personal injury or death from carbon monoxide poisoning and oxygen depletion.
