NOTICE

The boiler must be inspected and started annually at the beginning of the heating season by a qualified service technician. In addition, the maintenance and care of the boiler designated on page 5 of this manual and explained on pages 6 through 8 must be performed to assure maximum boiler efficiency and reliability. Failure to service and maintain the boiler and system could result in equipment failure, causing possible severe personal injury, death, or substantial property damage.

area.

Check pressure/temperature gauge

1.Make sure the pressure reading on the boiler pressure/ temperature gauge does not exceed 24 psi. Higher pressure may indicate a problem with the expansion tank.

2.Contact a qualified service technician if problem persists.

Check vent piping

1.Visually inspect the flue gas vent piping for any signs of blockage, leakage, or deterioration of the piping. Notify your qualified service technician at once if you find any problems.

death.

￿WARNING

To prevent potential of severe personal injury, death, or substantial property damage, eliminate all materials discussed below from the boiler vicinity and the vicinity of the boiler combustion air inlet. If contaminants 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 boiler for possible damage from acid corrosion.

If products cannot be removed, immediately call a qualified service technician to re-pipe vent and air piping and locate vent termination/air intake away from contaminated areas.

Check air piping

1.Visually inspect the air inlet termination to be sure it is unobstructed. Inspect the entire length of air piping to ensure piping is intact and all joints are properly sealed.

2.Call your qualified service technician if you notice any problems.

Check relief valve

1.Inspect the boiler relief valve and the relief valve discharge pipe for signs of weeping or leakage.

2.If the relief valve often weeps, the expansion tank may not be working properly. Immediately contact your qualified service technician to inspect the boiler and system.

Check condensate drain system

1.Combustible/flammable materials -- Do not store combustible materials, gasoline or any other flammable vapors or liquids near the boiler. Remove immediately if found.

2.Air contaminants -- Products containing chlorine or fluorine, if allowed to contaminate the boiler intake air, will cause acidic condensate in the boiler. This will cause significant damage to the boiler if allowed to continue.

1.Inspect the condensate drain line, condensate PVC fittings and condensate trap.

Fill condensate trap with water

1.Remove the bezel on the front of the unit.

2.Remove the PVC cap retaining screw from the PVC cap (FIG. 2-1).
