Step 4: Connect Electricity
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
