Step 4: Connect Electricity

WARNING
ELECTRIC GROUNDING INSTRUCTIONS
This appliance (120V ovens only) is equipped with a three-prong (grounding) plug for your protection
against shock hazard and should be plugged directly into a properly grounded three-prong
receptacle. Do not cut or remove the grounding prong from this plug.
NOTICE
This appliance, when installed, must be electrically grounded in accordance with local codes, or in the
absence of local codes, with the
National Electrical Code, ANSI/NFPA 70 or the Canadian Electrical
Code, CSA C22.2 , as applicable.
Wiring diagrams are located on the side of the control panel assembly, as well as in this manual (beginning
on page 21). Be sure that the input voltage and phase match the requirements shown on the serial plate,
which is located inside the lower front panel.
Ovens ordered to operate on 120V power have a three-wire cord. (Double-deck ovens have two power
cords, one for each oven.) Each cord has a three-prong plug that fits any standard three-prong grounded
receptacle. Single-oven units require a 15 ampere supply, while double-oven units require a 20 ampere
supply.
Step 5: Connect Gas Supply
NOTICE
The installation must conform with local codes, or in the absence of local codes, with the National
Fuel Gas Code, ANSI Z223.1, Natural Gas Installation Code, CAN/CGA-B149.1, or the Propane
Installation Code CAN/CGA-B149.2, as applicable, including:
1. The appliance and its individual 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 (3.45
kPa).
2. The appliance must be isolated from the gas supply piping system by closing its individual manual
shutoff valve during any pressure testing of the gas supply piping system at test pressures equal to
or less than 1/2 psi (3.45 kPa).
A 3/4" NPT line is provided at the rear for the gas connection.
If this equipment is being installed at over 2,000 feet altitude and that information was not specified when
ordered, contact the appropriate authorized Sierra Service Representative or the Sierra
Service Department.
Failure to install with proper orifice sizing will result in poor performance and may void the warranty.
The serial plate is located inside the front lower panel. It indicates the type of gas the unit is equipped to burn.
All Sierra equipment is adjusted at the factory. Check type of gas on serial plate.
These models are design-certified for operation on natural or propane gases. For natural gas, the regulator is
set to deliver a 3.5" W.C. pressure to the manifold. For propane gas, it is set to deliver 11" W.C.
This appliance should be connected ONLY to the type of gas for which it is equipped. The inlet pressure
before the regulator should be 6-10" W.C. for natural gas or 11-14" W.C. for LP gas.
