INTRODUCTION
WHAT DOES THE VENT DO?
The Vent-Sure Kiln Ventilation System is designed to pull
air contaminated with carbon monoxide and other fumes
including those of volatile metals, decals, sulfur oxide, and
others in a down draft fashion out of the kiln and then vent it
outside or to a central vent system.
KILN VENTILATION CAUTIONS
VENTILATION IS ESSENTIAL
1. Kilns generate harmful fumes when firing ceramics
including: carbon monoxide, sulfur oxides, hydrogen
fluoride and metal vapors (all of which can be toxic).
2. Install kiln in a well-ventilated area and never operate
in an enclosed space unless you have good airflow.
3. Severe corrosion can be caused by kiln fumes, salt air
,or other environmental conditions.
AMBIENT HEAT AND VENTILATION
1. The kiln should operate in an environment that is
between -18°C (0°F ) and 38°C (100°F).
2. Kiln vents do not take care of ambient ventilation of the
kiln room to remove the heat of the kiln.
3. See the following web page for guidance on how to
calculate ventilation requirements for a kiln room:

INSTALLATION
IMPORTANT CAUTION
MAKE CERTAIN KILN POWER IS OFF BEFORE
PROCEEDING WITH INSTALLATION.
Step 1. Turn Off Kiln Power
This is critical for safety reasons.
Step 2. Drill Holes (if needed)
Before mounting the Bypass Box, you should drill the vent
holes. (Note: if you bought the vent system with a new kiln,
it should be pre-drilled) The easiest way to drill the vent
holes is to place the stand upside-down on the kiln bottom,
center it, and then drill your holes within the large aperture.
Otherwise you can measure out the center of your kiln slab
and draw a circle in the middle with a radius of 1.5” Then
drill your vent holes within that circle.
Step 3. Install Bypass Collection Box
With the vent holes taken care of, you can install the Bypass
Collection Box. Just simply use the studs on the bottom of
the stand and secure with the provided hardware.
IMPORTANT: Remember to have the outlet pointed towards
your fume exhaust location.
The Bypass Collection Box is mounted to the bottom of the
stand with provided hardware.
Step 4. Install Blower System
Install blower system by penetrating outside wall or setting
into a window with appropriate support. Attach the provided
90 degree elbow to point down on the outside of the building
(this is to prevent rain water from getting into the duct).
(Note: this procedure will change if you use the Multi-Mount
bracket). Mount securely because motor may vibrate over
time especially if it builds up any dust in the blower.
The motor assembly comes pre-mounted onto the Wall mount
bracket:
3” Diameter Inlet
4” Diameter
Outlet
