Outdoor Knight XL User’s Information Manual

Read the list of potential materials listed in Table 1A on page 4 of this manual.

Check pressure/temperature gauge

￿WARNING

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

1.Make sure the pressure reading on the boiler pressure/ temperature gauge does not exceed 24 psi (165.5 kPa). Higher pressure may indicate a problem with the expansion tank.

2.Contact a qualified service technician if problem persists.

Check all piping for leaks

severe personal injury, death, or substantial property damage.

The following information provides detailed instructions for completing the maintenance items listed in the maintenance schedule on page 5. In addition to this maintenance,

￿WARNING

Eliminate all system or boiler leaks. Continual fresh makeup water will reduce boiler life. Minerals can build up in sections, reducing heat transfer, overheating heat exchanger, and causing heat exchanger failure. Leaking water may also cause severe property damage.

found.

￿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.

3. Contact a qualified service technician if problem

persists.

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.

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.

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.

Check condensate drain system

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

Fill condensate trap with water

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

2.Remove the 2" PVC cap with the switch located at the top of the trap (FIG. 2-1).

3.Fill with fresh water until the water begins to pour out of the drain.

4.Replace the cap. Press the cap onto the trap until the cap makes contact with the drain.

5.Replace the retaining screw.
