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.

!WARNING:

If you do not follow these instructions exactly, a fire or explosion may result causing personal injury, loss of life, or property damage.

d. WHAT TO DO IF YOU SMELL GAS: Do not try to light any appliance. Do not touch any electric switch and do not use any phone in your building. Immediately call your gas supplier from a neighbor’s phone. Follow the gas supplier’s instructions. If you cannot reach your gas supplier, call the fire depart- ment.

e.Use only your hand to push in the gas control lever. Never use tools. If the lever will not push in by hand, don’t try to repair it. Call a qualified service technician. Force or at- tempted repair may result in a fire or explo- sion.

f.Do not use this furnace if any part has been under water. Immediately call a qualified service technician to inspect the furnace and to replace any part of the gas valve or control system which has been under water.
