The vent does not have to be piped
The vent cannot be plugged. It can be piped, but it is much easier to just use a vent limiter. The unit must be mounted in the upright position as shown when using a vent limiter. Model numbers that end with the letter "L" come with the vent limiter installed.
Doesn't need to be piped as far as our local code is concerned. I used this to add a natural gas grill to my system -- same device as on my furnaces and other gas appliances. Set it up using a water-tube manometer made from clear plastic tubing -- worked like a champ.
These units must be mounted in a horizontal upright position when using a vent limiting device.
The 325-3 with the standard outlet spring is adjustable from 4" to 12" wc pressure. It can be custom-ordered with different springs that have different pressure ranges.
