IF YOU CAN SMELL FLUE GASES IN THE HOME, IT IS
A SIGN OF LEAKAGE SOMEWHERE IN THE FLUE
SYSTEM. CHECK FOR LEAKAGE AT ALL JOINTS OF
THE FLEX DUCT (AT THE HEATER CONNECTION AND
THE VENT TERMINAL). MAKE SURE THE SMOKE
SAMPLING PORT IS SEALED WITH THE COVER AND
GASKET (Figure 7).
ANNUAL INSPECTION
Once a year inspect all vent joints for leakage as
described in the section under “Initial Setup”. Inspect the
outside vent terminal and remove any debris which may
have accumulated.
Perform a combustion test and overfire test as described
in the same section.
Repair all leaks as required and make the necessary
burner adjustments to obtain the prescribed smoke
readings at the maximum overfire pressure.
Replace leaking band clamps with new ones as required.
