Clock Natural Gas Meter

Clock natural gas meter to verify input
1. Ensure all other gas equipment served by the meter is
turned off during timing of gas input to the Vitodens
100-W boiler.
2. Measure the time in seconds it takes for the boiler
to use 10 cu. ft. of gas. Divide 3600 x 10 by the
number of seconds and you get the number of cu. ft.
of gas used per hour. Multiply this number by the
heating value of the gas to obtain Btu per hour input.
CAUTION
Always contact your gas utility to obtain the correct
heating value before clocking the meter.
IMPORTANT
A boiler under fired by 5% is still acceptable.
Do not over fire the boiler.

6. Use to select "Burner mod. set value".
7. OK
8. Set the lower heating output:
Select "Minimum heating output".
Confirm with "OK".
The burner now operates at the lower heating output.
9. Set the upper heating output:
Select "Maximum heating output".
Confirm with "OK".
The burner now operates at the upper heating output.
The control unit must be matched to the system
equipment level.
For example:
A Vitodens 100-W 150 boiler (150 000 Btu/h input)
requires 240 seconds to use 10 cu. ft. of natural gas.
After contacting the local utility, you find the heating
value is e.g.
1000 Btu per cu. ft.
Therefore,
((3600 x 10)/240) x 1000 { 150 000 Btu/h input.
Therefore, the boiler input is correct.
Burner input formulas:
INPUT=(3600 + t) x 1000 where
t=TIME (sec.) for 1 ft.3
INPUT=(3600 x .01 x 1000 x 35.31) + T where
T = TIME (sec.) for .01 m3 natural gas
Reset maintenance (after maintenance has been
carried out)
1. and OK simultaneously for approx. 4 sec, then
release.
