a.Input for PROPANE is approximately at rating shown on ating plate when manifold pressure is 9-1⁄2" water column

b.Input for NATURAL GAS is approximately at rating when manifold pressure is 3-1/2" water column, but should be checked on the gas meter:

Btuh Input = Btu/cu. ft. metered in 3 minutes x 20

EXAMPLE #1:

For 1000 Btu/cu. ft. gas, this becomes:

Btuh Input = cu. ft. metered in 3 minutes x 1000 Btu/cu. ft. x 20

EXAMPLE #2:

For 1050 Btu/cu. ft. gas, this becomes:

Btuh Input = cu. ft. metered in 3 minutes x 1050 Btu/cu. ft. x 20

4.The higher heating value of gas varies substantially for different localities. Consult with Slant/Fin’s Technical Ser- vice Department for reorificing procedures if any of the following apply:

a.Boiler (burner) is over firing. CAUTION! National Fuel Gas Code (ANSI Z223. -latest edition) does NOT per- mit firing at a higher input rate than the input rate indi- cated on the boiler rating plate in order to avoid haz- ardous conditions such as explosion or carbon monox- ide poisoning.

b.Poor higher heating value of gas is causing the actual input to be substantially lower than the rating plate indication.

INTEGRATED BOILER CONTROL

The integrated boiler control monitors the status of the room thermostat, high limit control (Aquastat), pressure switch and the flame sensor. It controls the operation of circulator, induc- er motor, gas valve and spark for pilot ignition. The boiler con- trol also determines the sequence of operation and timing for pre and post purge periods, trail for ignition and lockout.

The control indicator lights (LED’s) provide information of boil- er operation when lights are steady on or diagnostic informa- tion when they are flashing in order to help to determine the cause of boiler failure.
