USER’S INFORMATION MANUAL
DC/HC SERIES BOILERS
MAINTENANCE
Daily Maintenance
•
Check the surrounding area – inspect for water leaks in the general area
around the boiler and boiler piping
•
Check the system pressure. The heating system pressure should not exceed
25psi and not drop below 10psi in most applications. If the pressure is outside
this normal range or if the water pressure fluctuates more than 2-3psi, contact
your qualified service technician for service.
•
Check the area around the boiler and the air intake opening for obstructions
and chemical contaminates.
Monthly Maintenance
•
Check all the Daily Maintenance items.
•
For DC series boilers, check the domestic hot water temperature at the faucet
to ensure the temperature is not too hot. If the temperature is too hot, you
can adjust the thermostatic mixing valve to a lower number, adjust the water
temperature with the boilers controller, or adjust the water temperature at the
hot water tank. If these adjustments are not correcting the issue, call your
qualified service technician for service.
•
Check the pressure relief valve and discharge piping for signs of leakage
or moisture. If water or moisture is found, contact your qualified service
technician as soon as possible for service.
•
Check the condensate trap and outlet pipe. The condensate trap shall be full
of water. The outlet hose may be connected to a condensate neutralizer, if so,
check the pH of the water coming out of the neutralizer is above 6.0pH. If the
pH is below 6.0 then the neutralizer will need to be re-charged or replaced.
Contact your qualified service technician for service.
Annual Maintenance
The boiler must be inspected by your qualified service technician for the following:
•
Inspect the flue gas exhaust and air intake connections. All connections
should be tight and leak free.
•
Inspect flue gas exhaust piping, combustion air piping and terminations.
•
Inspect the boilers interior and vacuum if required.
•
Check for water, gas and condensate leaks in the boiler and around the boiler.
•
Check the condensate trap and clean if required. Re-fill the trap and re-install
the trap hook.
•
Check the water pressure, expansion tank and pumps.
•
Check the electrical connections.
•
Check the ignition electrode and remove oxidation from the electrode.
Replace if necessary.
•
Check the gas valve and ignition cable.
•
Check the controller settings.
•
Check the burners flame. Should be a quick and quiet ignition across the full
burner.
•
If required, clean the heat exchanger and the burner.
