Maintenance Schedules - Baxi DUO-TEC COMPACT 30 GA Instructions For The End User

10. MAINTENANCE SCHEDULES

DAILY MAINTENANCE
Check the surrounding area
WARNING
The Boiler must be inspected and serviced annually, preferably at the start of the heating season, by a qualified service
technician. In addition, the maintenance and care of the boiler must be performed to assure maximum efficiency and
reliability of the unit. Failure to service and maintain the Boiler and the system components could result in equipment
failure, causing possible severe personal injury, death or substantial property damage.
WARNING
To prevent potential of severe personal injury, death or substantial property damage, eliminate all the potential
dangerous materials from the area surrounding the unit and from the vicinity of the combustion air inlet. If contaminates
are found: Remove products immediately from the area. If they have been there for an extended period, call a qualified
service technician to inspect the unit for possible damage from acid corrosion. If products cannot be removed,
immediately call a qualified service technician to re-pipe the combustion air inlet piping and locate the combustion air
intake away from the contaminated areas.
1. Combustible / Flammable materials - Do not store combustible materials, gasoline or other flammable vapors or liquids near
the unit. Remove immediately if found;
2. Air contaminates - Products containing chlorine or fluorine, if allowed, contaminate the combustion air, will cause acidic
condensate within the unit. This will cause significant damage to the unit. If any potentially dangerous products are in the
room where the boiler is located, they must be removed immediately or the combustion air intake must be relocated to
another area. Check Combustion Air Inlets verify that the unit's vent termination and combustion air intake are clean and free
of obstructions. Remove any debris on the air intake or flue exhaust openings. If removing the debris does not allow the unit
to operate correctly, contact your qualified service technician to inspect the unit and the vent /combustion air system. Check
Pressure Gauge, ensure the pressure reading on the pressure gauge does not exceed 25.5 psi (1.8 Bar).
MONTHLY MAINTENANCE
Check Vent Piping
Visually inspect the flue gas vent piping for any signs of blockage, leakage or deterioration of the piping. Notify a qualified service
technician immediately if any problems are found.
WARNING
Failure to inspect the venting system, as noted, and have it repaired by a qualified service technician can result in the
vent system failure, causing severe personal injury or death.
Check Intake Air Vent Piping
1. Visually inspect the intake air vent piping for any signs of blockage. Inspect the entire length of the intake air vent piping to
ensure piping is intact and all joints are properly sealed;
2. Notify a qualified Service Technician if any problems are found.
Check Pressure Relief Valve
1. Visually inspect the pressure relief valve and the relief valve discharge pipe for signs of weeping or leakage;
2. If the pressure relief valve often weeps; the expansion tank may not be operating properly. Immediately contact a qualified
Service Technician to inspect the unit and system.
Check Vent Condensate Drain System
1. While the unit is running, check the discharge end of the condensate drain tubing. Ensure no flue gas is leaking from the
condensate drain tubing or tee connection by holding your fingers near the opening;
2.
If you notice flue gas leaking from the opening, this indicates a dry condensate drain trap. Fill the condensate trap assembly.
Contact a qualified Service Technician to inspect the unit and condensate line and refill the condensate trap if problem
persists regularly;
3. The Service Technician must ensure the condensate drain line is not blocked by pouring water through the condensate drain
assembly (condensate trap). The water should flow out of the end of the drain line. If water does not appear at the end of the
drain line, the qualified service technician must clean the condensate line.
WARNING
You must make sure the condensate hose is securely fastened before restarting the boiler. Do a final check to assure
proper flow.
