- Attach the second 45 degree elbow on the other side of the wall, turning the angle upward
to run parallel with the wall. Install the second piece of ute pipe into the elbow, parallel to
the outside wall. Utilize galvanized steel brackets or clamps as necessary to secure the
piping. Install the rain/wind cap on top of the second piece of exhaust pipe.
- Install a condensation drain on the portion of pipe located outside the structure.
- Through the roof installations: Use one piece of straight pipe, 60” or shorter, a wind/rain cap
and a condensation drain. Attach directly to the outlet of the unit (16L units).
- Drill a hole through the roof and ceiling slightly larger than the vent pipe diameter. Attach
pipe to the top of the unit and go straight up and out the roof. Install rain/wind cap on top of
vent pipe. Total vertical distance must not exceed 60”. Roof clearance must be at least 12”.
- Fresh air intake: The room in which the heater is located must have an air inlet not less than
.75 square feet (roughly 9” x 12” or larger).
**NOTE: If your situation requires a vent pipe distance of longer than 60”, a low CFM
duct booster fan may need to be employed to ensure proper venting of the unit and
install two D Cell batteries. Check the door of the battery
compartment for correct battery position.
