GAS SUPPLY
The local gas authority or supplier should be consulted at the installation planning stage in order to
establish the availability of an adequate supply of gas (NG or LP). If it is a new installation, have the
gas authorities or supplier check the meter size and piping to assure that the unit is supplied with the
necessary amount of gas supply and pressure to operate the unit(s).
Gas connections should be made by a qualified plumber, or your professional appliance installer.
All appliances must be fitted with an accessible upstream gas shutoff valve as a means of isolating the
appliance for emergency shut off and for servicing.
Make certain new piping and connections have been made in a clean manner and have been purged
so that piping compound, chips, etc. will not clog regulators, valves, orifices, or burners. Use pipe
joint compound / thread sealant approved for natural and LP gases.
The appliance and its individual manual shutoff valve must be disconnected from the gas supply
piping system during 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 individual manual
shutoff valve during any pressure testing of that system at test pressures equal to or less than 1/2 psi
[3.5 kPa].
NEVER CONNECT THE APPLIANCE TO AN UNREGULATED GAS SUPPLY. Before proceeding,
ensure the appliance is fitted for Natural or Liquid Propane gas. Connecting to an improper gas type
will result in poor performance and increased risk of damage or injury. Gas type and gas consumption
(BTU per hour) for each burner type is shown on the rating label.
Installation of this cooking appliance must be made in accordance with local codes. In the absence of
local codes, this unit should be installed in accordance with the National Fuel Gas Code No. Z223.1/
NFPA 54, Natural Gas and Propane Installation code CSA B149-1, or Propane Storage and Handling
Code B149.2.
NOTE: See rating label for manifold pressure for the type of gas of your appliance.
The gas connection at the back of the range (see below) features
1/2”NPT internal threads. Connect to gas supply using a minimum
3/4” inside diameter (1” OD) flexible (semi–rigid) stainless steel gas
hose with appropriate end fittings to prevent gas starvation. This hose
should be no more than 48” [1.2 m] in length. Use the appropriate
thread sealant on all connections. Do not apply sealant to flare
fittings.
The supply line 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 flex 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.
