Operation

4.4 Sampling Point

Forced Air Furnace – For atmospheric burner or gravity vented, forced air heating equipment with a clamshell or sectional heat exchanger de- sign, test each of the exhaust ports at the top of the heat exchanger. The probe should be inserted back into each of the exhaust ports to obtain a flue-gas sample, before any dilution air is mixed in.

Hot Water Tank – Domestic hot water tanks with the ‘bell’ shaped draft diverter can be ac- curately tested by inserting the probe tip directly into the top of the fire tube below the diverter.

80% Efficiency Fan Assist or Power Vented

– Combustion testing of fan assist or power vented, furnaces/boilers should be done through a hole drilled in the vent immediately above the inducer fan.

90% Efficiency Condensing – Condens- ing furnaces/boilers can be tested through a hole drilled in the plastic vent pipe (when allowed by the manufacturer or local authority of jurisdiction) or taken from the exhaust termination.

Atmospheric or Gravity Vented Boiler

– Boilers, which have a ‘bell’ shaped draft diverter on top, should be tested directly below the diverter through a hole drilled in the vent connector.
