CALIBER B-VENT INSTALLATION INSTRUCTIONS
6. Install the Outside Air Kit
An outside air kit is available as an optional feature
with this appliance. An outside air kit helps to decrease
the amount of room air taken by utilizing outside air
for combustion. It is strongly recommended that it be
installed.
The outside air kit can only be installed on the left
side of the appliance.
To install the outside air kit, refer to the installation
instructions provided with the kit.
Note:
The outside air kit can terminate at any level with
the exception that it must terminate at least one foot
below the vent termination cap. The outside air kit inlet
thimble should be positioned at least 4 ft above the
ground level in a manner that will not allow snow, leaves,
etc. to block the inlet.
F. UTILITIES
1. High Altitude Installation
For U.S. installation, gas appliances are tested and approved for elevations from 0-2000 feet. When installing this
gas appliance at an elevation above 2000 feet, National Fuel Gas Codes require a decrease of the input rating by
changing the existing burner orifice to a smaller size. Input should be reduced 4% for each 1000 feet above sea
level. Check with the local gas utility for proper orifice size identification. The correct orifice is available from your
Hearth & Home Technologies distributor.
For Canada, gas appliances are certified for elevations from 0-4500 feet. When installing this gas appliance at an
elevation between 0-4500 feet in Canada, the input rating does not need to be reduced. When installing this gas
appliance at an elevation above 4500 feet in Canada, check with local authorities.
2. Gas Line Connection
The appliance is provided with a stainless steel flexible connector and a listed (and Commonwealth of Massachusetts
approved) tee-handle manual shutoff valve. See Figure 10. The incoming gas line should be piped into the valve
compartment and connected to the 1/2 in. FIP connection provided on the manual shutoff valve. See Figure 11 to
connect the gas line.
Optional:
Seal around the gas line to prevent cold air leakage.
All connections must be tightened and checked for leaks with a commercially available, non-corrosive leak check
solution. Be sure to rinse off the solution when done leak testing.
Bleed the gas line to extract any air that may have been trapped inside the pipe.

WARNING!
Exhaust products of gasoline engines are hazardous. The outside air must not be taken from a garage space,
attic spaces, basements or above the roofing where other heating appliances, fans or chimneys exhaust or
utilize air.
