For more detailed burner start-up information, refer to the burner
literature supplied as an appendix to this manual relative to the actual burner
supplied with your unit.
IV. OPERATION AND MAINTENANCE
A.
OPERATION
1.
When the operating controller calls for pressure, the burner blower motor will
start and after a suitable prepurge period (30-90 seconds approximately) the
burner pilot will light. (The unit performs its own safety check and opens the main
valve only after the pilot is proven to be lit). The main flame is then established.
2.
The operating controller will control to the desired steam pressure. The
differential adjustment should be set at the highest value which will still provide
acceptable steam pressure variation. Two pressure controllers are supplied on hi-
lo fired units, and a proportional controller is supplied on modulating burners.
3.
An automatic reset pressure limit is supplied as standard on all modulating units.
4.
A manual reset high limit is provided as standard equipment on all units. The
burner will automatically shut down whenever an over pressure condition occurs.
5.
A manual reset low water cutoff is also provided as standard equipment on all
units. The low water cutoff automatically shuts off the burner whenever the water
level drops below the Factory set level in the upper part of the tank.
NOTE:
Warranty does not cover any damage caused by lack of required
maintenance or improper operating practices.
B.
MAINTENANCE
1.
At startup and at least every six months thereafter, the pilot and main burner
flame should be observed for proper performance. (Refer to burner literature
supplied with this manual for detailed information).
2.
Inspect the venting system for obstruction, leakage, and corrosion at least once
per year.
3.
Keep Boiler area clean and free from combustible material, gasoline and other
flammable vapors and liquids.
4.
Be certain all combustion air and ventilation openings are unobstructed.
5.
The gas and electric controls installed on these Boilers are engineered for both
dependable operation and long life, but the safety of this equipment completely
depends on their proper functioning. It is strongly recommended that the basic
