Question:
This summer I bought and installed a Hearthstone Sterling Direct Vent LP stove. Installation is complete but stove will not stay lighted and even the pilot goes out after a few minutes. Trouble shooting guide talks about adjusting the thermo pile height. Pilot does not engulf the top 1/2 " of the thermopile as it should. How is this done? The stove is vented into an existing chimney which is approx. 20 feet high. Is it mandatory to install a restrictor plate in the exhaust vent? Thank you.
Answer:
There is usually a pilot adjustment screw on the valve. Check some other things, in this order:
1. Is the LP tank full?
2. Has the output of the LP pressure regulator (on the tank) been checked?
3. It's possible that a piece of dirt has partially clogged the pilot orifice.
Check with your dealer or HearthStone after you or your installer have undertaken these steps.
