MAINTENANCE

9. MAINTENANCE

A.GENERAL (WITH BOILER IN USE)

General boiler observation can be performed by the owner. If any potential problems are found, a qualified installer or service technician/agency must be notified.

1.Remove any combustible materials, gasoline and other flammable liquids and substances that generate flammable vapors from the area where the boiler is contained.

2.Observe general boiler conditions (unusual noises, vibrations, etc.)

3.Observe operating temperature and pressure on the combination gauge located in the supply piping on the left side of the boiler. Boiler pressure should never be higher than 5 psi below the rating shown on the safety relief valve (25 psig maximum for a 30 psig rating). Boiler temperature should never be higher than 240° F.

4.Check for water leaks in boiler and system piping.

5.Smell around the appliance area for gas. If you smell gas, follow the procedure listed in the Lighting Operating Instructions to shut down appliance in Section 7, Start-Up Procedure Part B.

B.WEEKLY (WITH BOILER IN USE)

1.Flush float-type low-water cut-off (if used) to remove sediment from the float bowl as stated in the manufacturer’s instructions.

C.ANNUALLY (BEFORE START OF HEATING SEASON)

CAUTION

The following annual inspection must be performed by a qualified service technician.

1.Check boiler room floor drains for proper functioning.

2.Check function of the safety relief valve by performing the following test:

a.Check valve piping to determine that it is properly installed and supported.

b.Check boiler operating temperature and pressure.

c.Lift the try lever on the safety relief valve to the full open position and hold it for at least five seconds or until clean water is discharged.

d.Release the try lever and allow the valve to close. If the valve leaks, operate the lever two or three times to clear the valve seat of foreign matter. It may take some time to determine if the valve has shut completely.

e.If the valve continues to leak, it must be replaced before the boiler is returned to operation.

f.Check that operating pressure and temperature have returned to normal.

g.Check again to confirm that valve has closed completely and is not leaking.

3.Test low-water cut-off (if used) as described by the manufacturer.

4.Test limit as described in Section 7, Part C, “Check- Out Procedure”.

5.Test function of ignition system safety shut-off features as described in Section 7, Part C, “Check- Out Procedure”.

DANGER

When servicing or replacing components, be absolutely certain that the following conditions are met:

●Water, gas and electricity are off.

●The boiler is at room temperature.

●There is no pressure in the boiler.

6.Remove the top/front jacket panel and inspect for any foreign debris that may have entered through air inlet vent.

7.Inspect burner for deterioration. Replace if necessary.

8.With boiler in operation check that condensate is dripping from drain hose. Check for any restriction in condensate drain line.

a. CONDENSATE CLEANING INSTRUCTIONS:

1.Turn the thermostat down or off so the Pinnacle will not cycle and then follow the steps below.

a.Close manual gas shutoff valve.

b.Disconnect the condensate piping from the outside connection (not from the Pinnacle) so flow can be observed.

c.Block the air flow in the exhaust by temporarily plugging the exhaust from the outside vent.
