ANNUALLY
Vent System • Inspect for blockages or damage.
• Inspect vent screen or room air lter (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 lubricaon).
Controller Clean by using a so, damp cloth. Do not use solvents.
Pressure Conrm the pressure is within the proper range (between 17-26 PSI). If the
pressure is lower than the specied range, add water unl 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 precauons with regard to the discharge of potenally
scalding hot water under pressure. Ensure discharge has a safe place to ow.
Contact with your body or other property may cause damage or harm.
Heang System
Dirt Trap
Clean annually. Be sure to close the shut o valves under the boiler. Aer
cleaning and installing the lter, purge the air.
Expansion Tank Perform annual checks as recommended by the manufacturer to ensure proper
operaon.
Condensaon
Trap
Check if the trap contains sediment. To remove sediment, unplug the boom of
the condensate trap. Remove the sediment, and then return the plug. Do not
use a wrench to ghten the condensate drain as this could cause the
connecon to break.
Condensaon
Drain
• Conrm the condensaon drain line is not blocked or clocked.
• Ensure the condensaon drain pump (if ulized) is working correctly.
Draining Water When the system will be shutdown for a long period of me (seasonal
shutdown), close the shuto valves below the boiler and drain the boiler to
protect it from potenal freeze damage.
Tesng 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.
