GENEVA SERIES B-VENT GAS APPLIANCE
F. UTILITIES
1. High Altitude Installation
For U.S. Installation, appliances are tested and approved for elevations from 0-2000 feet. When installing this 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 Heatilator distributor.
For Canada, appliances are certified for elevations from 0-4500 feet. When installing this appliance at an elevation
between 0-4500 feet in Canada, the input rating does not need to be reduced. When installing this appliance at an
elevation above 4500 feet in Canada, check with local authorities.
2. Gas Line Connection
Remove/open the control access panel as shown in Figures 11 and 12.
The appliance is provided with a stainless steel flexible connector and a listed (and Commonwealth of Massachusetts
approved) T-handle manual shutoff valve. The incoming gas line should be piped into the valve compartment and
connected to the 1/2 FIP connection provided on the manual shutoff valve. See Figure 13 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 soap and water solution or a leak detector.
Bleed the gas line to extract any air that may have been trapped inside the pipe.

Note:
This appliance and its manual shutoff valve must
be disconnected from the gas supply piping system dur-
ing any pressure testing of that system at test pressures
in excess of 1/2 psi (3.5 kPa). The appliance must be
isolated from the gas supply piping system by closing its
manual shutoff valve during any pressure testing of the
gas supply piping system at test pressures equal to or
less than 1/2 psi (3.5 kPa).

OPTIONAL: Seal around the gas line to prevent
cold air leakage.
Note:
Have the gas supply line installed in accordance with building codes by a qualified installer approved and/or
licensed as required by the locality. In the Commonwealth of Massachusetts, installation must be performed by a
licensed plumber or gas fitter.
