9.6 Check Combustion 

Natural Gas

1. 

Measure input. English unitsTurn off gas to all other 

appliances.

• Activate some heating zones to dissipate heat.
• Set boiler on high 

fi

 re.

• Use ½, 1 or 2 cu ft dial on gas meter.  Measure 

time required for one or more complete 

revolutions.  Measure time for 1-2 minutes.

• Calculate input.

Input (MBH)

=

3600 x        cu ft
           seconds

Example: Gas 

fl

 ow from

 

Meter = 2 cu ft 

 

Measured time = 72 seconds

 

  Rate (MBH)

=

3600 x   2 cu ft

=

100 MBH

    72  seconds

Two sampling points are available at top of the boiler, one 

for venting and the other for combustion air. To sample:

Open the air/vent outlet plug.

Insert probes all the way in.

Turn on TEST mode, wait 10 minutes for boiler to stabilize;

Take measurement.
