Section 4 - Chimney/Vent System
General Requirements
1.
Safe operation of any gravity vented heating appliance requires a proper air make-up
system to prevent the heater exhaust gases from being drawn into the building. These
gases could cause death, serious injury, and/or property damage. Exhaust fans and
paint
booths may cause draft problems.
2.
Never vent this heater into another heating appliance’s chimney. Never vent into ‘Class B”
chimney. Gas heaters use “Class B” chimney. It is rated for a much lower temperature than
is required for your waste-oil furnace. This heater must have its own separate “Class A”
chimney.
3.
Inspect and maintain the chimney on an annual basis.
4.
A U.L. listed barometric damper
MUST
be installed in
the chimney or the
WARRANTY WILL BE VOID
. Do not
reduce or enlarge the vent pipe.
5.
Minimize or eliminate horizontal runs and angle/elbow
connections, where possible. Consider chimney clea-
nout access when installing. If your installation fails to
acheive proper draft, consider lengthening the vertical
chimney.
Contact Lanair for Assistance with special installation
circumstances.
6.
To prevent the drawing of exhaust gases into the build-
ing, keep the barometric draft control at least 3 feet from any fan, blower, etc..
7.
The position of the draft control Barometric Damper gate hinge pins must be horizontal
(parallel to the floor) for proper operation.
8.
Secure all connections in the chimney connector with 3 screws per joint.
9.
Clearance for the chimney connector and any single-wall flue to any combustible mate-
rial is 18”. The “Class A” chimney clearance to any combustible is 2”. Follow the chimney
manufacturer’s instructions.
Failure to provide proper venting of the heater exhaust gases could
result in death, serious injury, and/or property damage. FOLLOW
CHIMNEY MANUFACTURERS INSTRUCTIONS.
