NOTE: A listed (and Commonwealth of Massachusetts
approved) 1/2 inch (13mm) T-handle manual shut-off valve and
fl exible gas connector are connected to the 1/2 inch (13mm)
control valve inlet.
• If substituting for these components, please consult
local codes for compliance.
NOTE: The gap between the supply piping and gas access
hole may be plugged with non-combustible insulation to prevent
cold air infi ltration.
C. Gas Connection
NOTE: Have the gas supply line installed in accordance with
local building codes, if any. If not, follow ANSI Z223.1. Instal-
lation should be done by a qualifi ed 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 fi tter.)
Leak test all gas line joints and the gas control valve prior
to and after starting the appliance.
Before making the gas connection, ensure that the appliance
you are installing is designed for the type of gas being
supplied. This information can be found on the ratings label
under the appliance. If the appliance has been converted
to propane (LP), the valve cover should have a label stating
that the appliance has been converted to propane.
Connect the gas line at the 3/8 in. (10mm) pipe connector
on the valve at the back of appliance. We recommend
connecting the appliance with an approved flex gas line.
If flex gas lines are not approved in your area, you must
connect a hard pipe to the gas hookup.
You must supply a manual shut-off valve in a visible location
within 3 ft. (914mm) of the appliance.
WARNING
Gas Leak Risk.
• Support control when attaching pipe to
prevent bending gas line.
HIGH ALTITUDE INSTALLATIONS
Omni-Test Laboratories, Inc. listed gas appliances are tested and
approved without requiring changes for elevations from 0 to 2000
feet in the U.S.A. and 0 to 4500 feet in Canada.
When installing this appliance at an elevation above 2000 feet,
it may be necessary to decrease the input rating by changing
the existing burner orifi ce to a smaller size. Input rate should be
reduced by 4% for each 1000 feet above a 2000 foot elevation
in the U.S.A. If the heating value of the gas has been reduced,
these rules do not apply. To identify the proper orifi ce size, check
with the local gas utility.
If installing this appliance at an elevation above 4500 feet (in
Canada), check with local authorities.
