4.2 Sampling Hole Location

The analyzer requires that a 13 mm (½ in.) diameter sampling hole be made in the furnace stack to accommodate the probe stop on the Probe and Hose Assembly.

Locate the sampling hole downstream from the last heat exchanger, and upstream from any source of dilution, such as a draft diverter (Figure 4-1).

IMPORTANT! As the distance between the last heat ex- changer and sampling point increases, stack loss will falsely decrease due to heat loss by convection from the flue or stack.

For residential and light-commercial combustion-equipment applications, the following recommendations are applicable:

•Oil Gun Burners – Locate sampling hole at least 30 cm (12 in.) down- stream from the furnace breaching, and at least 15 cm (6 in.) upstream from the furnace side of the draft regulator.

•Gas Burners – Locate sampling hole at least 15 cm (6 in.) upstream from the furnace side of the draft diverter on gas-converted units. For gas- designed equipment, the probe may be inserted down into the flue through the draft diverter or hood.
