Example Forced Air Furnace Example Hot Water Tank
For atmospheric burner
or gravity
vented, forced air heating equipment
with a clamshell or sectional heat
exchanger design
, 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.
Domestic hot water tanks with the ‘bell’
shaped draft diverter can be accurately
tested by inserting the probe tip directly
into the top of the fire tube below the
diverter.
