15. FLUE GAS SAMPLING
It may be necessary to take fl ue gas sampling
from oil and gas gun furnaces (M1S and M1B

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, fi ll 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.
