15. FLUE GAS SAMPLING
It may be necessary to take flue gas sampling
from oil and gas gun furnaces (M1S and M1B
Series Models) in order to check the perfor-
mance after furnace installation. A flue gas
sample may be taken from the heat exchanger,
which is located behind the hole of the top-front
of blower compartment.
1. STOP! Read the SAFETY INFORMATION.
2. Turn off all electric power to the appliance.
3. Remove the black plastic cap located above
the blower and save.
4. Through the top of the blower compartment
hole, drill a hole for your sampling tube into the
heat exchanger.
5. Insert sampling tube through the drilled hole.
6. After a complete check and adjustment of
furnace performance, fill the drilled hole with
a screw that is larger than the hole.
7. Put silicon sealant (rated at least 500° F)
around the screw.
8. Plug the outside hole with the plastic cap you
removed in step 3.
