Series Condensing Boiler Combi Manual
TWO YEAR SERVICE
Vent System
•
Inspect for blockages or damage.
•
Inspect vent screen or room air filter (if using) for debris and blockages. Clean
if needed.
Fan and Motors
Clean dust and dirt from fan and motor (motors are permanently lubricated and
do not require lubrication).
Controller
Check diagnostic code history.
Pressure
Confirm the pressure is within the proper range (between 17
-
26 PSI). If the
pressure is lower than the specified range, add water until in the proper range.
Pressure Relief
Valve
Operate the pressure relief valve manually once a year. In doing so, it will be
necessary to take precautions with regard to the discharge of potentially scalding
hot water under pressure. Ensure discharge has a safe place to flow. Contact
with your body or other property may cause damage or harm.
Expansion Tank
Perform annual checks as recommended by the manufacturer to ensure proper
operation.
Condensation
Trap
Check if the trap contains sediment. To remove sediment, unplug the bottom of
the condensate trap. Remove the sediment, and then return the plug. Do not use
a wrench to tighten the condensate drain as this could cause the connection to
break.
Condensation
Drain
•
Confirm the condensation drain line is not blocked or clocked.
•
Ensure the condensation drain pump (if utilized) is working correctly.
Draining Water
When the system will be shutdown for a long period of time (seasonal
shutdown), close the shutoff valves below the boiler and drain the boiler to
protect it from potential freeze damage.
Water Quality
Confirm the water quality. Refer to section
“
4.4.1 Water Quality Guidelines
”
to
determine if the water needs to be treated or conditioned. DHW must be
potable, free of corrosive chemicals, sand, dirt, or other contaminates. It is up to
the installer to ensure the water does not contain corrosive chemicals or
elements that can affect or damage the heat exchanger. Water that contains
chemicals exceeding the levels required affect and damage the heat exchanger.
Replacement of the heat exchanger due to water quality damage is not covered
by the warranty.
Testing the pressure relief valve should only be
performed by a licensed professional. Water
discharged from the pressure relief valve could cause severe burns
instantly or death from scalds.
