GAS CONNECTION
(CONTINUED)
Connect to the gas supply using a mininum 3/4” inside diameter (1” OD) flexible (semi-rigid) stainless
steel gas hose (not included) with appropriate fittings to prevent gas starvation. This hose should be
no more that 48” [1.2m] in length. Use the appropriate thread sealant on all connections, except flare
fittings.
The gas hose must not interfere with the rear of the range. Use caution when pushing the range
against the back wall, so that you do not kink or crimp the hose as this could result in a gas leak.
CONVERSION KITS
In the event your Hestan appliance needs to be converted from NG to LP, or vice-versa, you will
need to contact Hestan Customer Service to arrange a service call. This conversion should only be
performed by a qualified technician.
HIGH ALTITUDE KITS
If you live in a high altitude area, 2,000 ft. [610 m] or more above sea level, your appliance may
require different orifices for proper combustion and performance. You will need to contact Hestan
Customer Service to arrange a service call. High Altitude kits must be installed by a qualified
technician. Please have your model and serial number information ready when you call.
GAS CONNECTION - NATURAL GAS (NG)
To ensure proper heating performance of this appliance, verify that the gas line supply pressure is
adequate. The appliance is supplied with a gas pressure regulator already installed. This regulator
is set for a supply (inlet) pressure of 7-14 inch WC [1.74-3.48 kPa] to maintain 5 inch WC [1.24 kPa]
nominal outlet (manifold) pressure. Ensure that the service pipe supplying the appliance is fitted
with a shut-off valve conveniently positioned and easily accessible as an emergency gas shut-off.
GAS CONNECTION - LIQUID PROPANE (LP)
If you purchased an LP version of your appliance, it will be supplied with a gas pressure regulator
already installed. This regulator is set to maintain 10 inch WC [2.49 kPa] nominal outlet (manifold)
pressure. Ensure that the service pipe supplying the appliance is fitted with a shut-off valve
conveniently positioned and easily accessible as an emergency gas shut-off.
When connecting to LP gas, verify the tank is equipped with its own high pressure regulator. The
pressure of the gas supplied to the appliance must be 11-14 inch WC [2.74-3.48 kPa].
LEAK TESTING
GENERAL
Although all gas connections on your Hestan appliance are leak tested at the factory prior to
shipment, a complete gas tightness check must be performed at the installation site due to possible
movement in shipment, or excessive pressure unknowingly being applied to parts of the unit.
Immediately check if the smell of gas is detected. Leak testing of the appliance shall be conducted
according to these instructions:
BEFORE TESTING
DO NOT SMOKE WHILE LEAK TESTING.
• Never leak test with an open flame.
• Make a soap solution of one part liquid detergent and one part water for leak testing purposes.
• Apply the solution to the gas fittings and flex hose by using a spray bottle or a brush.
TO TEST
• Make sure all control knobs are in the “OFF” position.
• Apply the soap solution to all fittings and flex hose.
• Turn the gas supply on.
• Check all connections from the supply line up to the regulator connection at the rear of the
appliance.
