Service Information

Test 1

Check ignitor circuit for correct resistance.

Remove 4-pin plug from control.

Check ohms reading across terminals 1 and 5.

Reading should be between 39 and 70 ohms. If

value is correct, this is the only test needed.

If the reading on the meter is not correct, (0 or

infinity) then a second test is needed.

Test 2

Check ignitor for correct resistance.

Seperate the 2-pin jack-plug near the manifold and check

resistance of ignitor at the plug. Reading should be

between 39 and 70 ohms. If the reading is correct, then

the problem is with the wiring between the jack-plug and

the control. If reading is not correct, the issue is the ignitor.

Test 3

Check ignitor for correct voltage

Insert meter probes into terminals 1 and 5 (use small

diameter probes in order not to damage plug).

Check voltage during 20 second ignitor warm up period.

Voltage should read 120 volts +

10%. If voltage reads below

these values, check for correct supply voltage to furnace.

As required.'MVe gas may be acidic and may adversely affect some building materials. *f a side wall vent

termination is used and flue gases will impinge on the building materials, a corrosionresistant shield

(24 inches square) should be used to protect the wall surface. *f optional tee is used, the protective shield

is recommended. The shield should be constructed using wood, sheet metal or other suitable material.

All seams, joints, cracks, etc. in affected area, should be sealed using an appropriate sealant.

Exhaust pipe 45° elbow can be rotated to the side away from the combustion air inlet to direct exhaust

away from adjacent property. The

exhaust must never be directed toward the combustion air inlet.
