Our Answer:

Both of the control levers you speak of are part of the outside air control box for your unit. The first lever, which is the control that goes up and down, is the lever that allows air to enter from outside. The second lever is the control for allowing the unit to draw air from inside the home or outside the home. In order to use outside air for combustion, you will need to have the first lever in the upward position (or left position, depending on how the control box was installed). This is as you face the unit. Then, you will need to pull the second lever toward you. The combination of these actions allows the unit to receive outside combustion air. This will most likely rectify the issue you are having. It is also necessary to leave the doors slightly cracked open until a good fire has been established. Once burning, the outside air system should provide plenty of air. If the system still does not function properly, it is possible there is a blockage in the outside air duct. It will be necessary to inspect the duct for any blockages and to determine if it has become pinched for any reason.

In Response to Question:

I have the NZ3000 and am having problems with the air flow into the unit. When I close the doors the fire almost goes out. I have to keep opening and closing the doors. How do I adjust the air flow to get maximum air into the unit? My unit has 2 controls one that goes up and down and one that goes in and out, both are under the fire box on the left hand side of the unit as you look at it. I think the in and out lever is opening or closing air to the outside of the house but I am not sure.
