Performing a Combustion Test
Important: The probe must be at room temperature before
performing the following steps.
1. Before turning ON the analyzer, position the probe or the optional
combustion-air thermocouple to measure the temperature of the
burner’s combustion air by performing one of the following:
• When NOT USING the Combustion-Air Thermocouple –
Before turning ON the analyzer, its probe must be located in
the area containing the burner’s combustion-air supply. If the
burner is using room air, then simply place the probe within the
room. In the case of a high-efficiency furnace where combustion
air is drawn in from an outside source, insert the probe into the
combustion-air stream so it can measure its temperature with
the burner op er at ing.
• When USING the Combustion-Air Thermocouple –
The analyzer’s second thermocouple channel can be used to inde-
pendently monitor the temperature of the burner’s combustion-air
supply while testing. When using this second thermocouple channel,
insert the thermocouple into the burner’s combustion-air stream,
and position the probe to measure the ambient room temperature.
2. Turn ON the analyzer as previously described. At the end of
warmup the Fuel Screen will be displayed.
3. Press either the or button to step through the fuels codes until
the proper fuel is selected. The analyzer defaults to the most re-
cent ly se lect ed fuel.
F1 = Natural Gas
F2 = Propane
F3 = Light Oil
F4 = City Gas
4. Press the ENTER button to select the displayed fuel code and enter
the Run Mode.

Water Trap / Filter Maintenance
The Water Trap / Filter Assembly removes water con den sate from the gas
sam ple, and also prevents soot from con tam i nat ing the internal com po -
nents of the analyzer.
Drain the water condensate after every test.
Procedure:
1. Pull off the Inlet End Cap using a slight twisting motion.
2. Pour out all water condensate; then reassemble trap.
Replace the Filter Element when dirty.
Material Required: • Filter Element, P/N 0007-1644
Procedure:
1. Pull off the Outlet End Cap using a slight twisting motion.
2. Remove and discard old filter.
3. Install new filter; then reassemble trap.
