Direct Venting Problems

Bruce_06 Member Posts: 2
I have a Weather King oil fired furnace equipped with a direct vent kit by field controls. The situation is the secondary safety switch continues to pop. However there are no signs of poor venting or improper combustion. I have checked the power supply and the amp draws on the exhaust fan and all operation is normal. If any one has any ideas anything will help.

    direct venting

    When all else fails, contact the rep for Field. Any time I have had to call on them they have been great with the tech support.

    Prevailing wind issue?

     which side of the house does it terminate?

    strong winds and a poorly protected termination location

    would be the first thing I would look at

    What is your stack temp? What is your draft? How is it wired in? Do you have a draft regulator? When is the last time you oiled the motor?
