PILOT BURNER FLAME (STG  PILOT UNITS)

NORMAL INSPECTION PROCEDURES

First and third month after initial start up and then on

an annual basis.  If problems are found, refer to Trouble

Shooting Guide for additional directions.

  1. Remove top of boiler  and inspect heat exchanger

for soot and examine venting system.

  2. Remove rear header and inspect for scale depos-

its.

*3. Inspect pilot and main burner flame and firing rate.

*4. Inspect and operate all controls and gas valve.

*5. Visually inspect system for water leaks.

*6. Oil pump motor and bearing assembly, if oil cups

are provided.

  7. Check flow switch paddle.

  8. Clean room air intake openings to assure adequate

flow of combustion and ventilation air.

  9. Keep boiler area clear and free from combustible

materials, gasoline, and other flammable vapors

and  liquids.

*Should be checked monthly.  (Takes approximately 15

  minutes).

SAFE SHUTDOWN TESTS

LIMIT ACTION

With the burner operating, lower the high limit

setting to simulate an overheated boiler.  Normal shut-

down should occur.  Restore the normal limit setting,

and the burner should restart.

FLAME FAILURE

With burner operating, close the manual fuel valves

to simulate a flame failure.  System should lock out after

safety switch timing (15 seconds).  After the safety

switch has cooled, open the manual valves (relight

standing pilots) and reset the safety switch; the burner

should restart.

INSPECTION PROCEDURES

BURNERS

Clean main burners and air louvers of dust, lint and

debris.  Keep boiler area clear and free from combus-

tibles and flammable liquids.  Do not obstruct the flow  of

combustion and ventilating air.  Make visual check of

burner and pilot flame.  Yellow flame indicates clogging

of air openings.  Lifting or blowing flame indicates high

gas pressure.  Low flame indicates low gas pressure.

NOTE: 

Modulating burner flame varies in height from

approximately 1/4" at low fire to approximately 4" in

high fire.
