Gas Supply
The importance of the proper installation of commercial
gas cooking equipment cannot be over stressed. Proper
performance of the equipment is dependent, in great part,
on the compliance of the installation with the manufacturer's
specifications. In addition, compliance with the National Fuel
code, ANSI Z223.1-1988(NFPA No. 54) or the latest edition
and/or local codes is required to assure safe and efficient
operation.
Before assembly and connection, check gas supply.
A. The type of gas for which the unit is equipped to stamp
on the data plate located behind lower front panel.
Connect a unit stamped "NAT" only to natural gas;
connect a unit stamped "PRO" only to propane gas.
B. If it is a new installation, have gas authorities check meter
size and piping to assure that the unit is supplied with
sufficient amount of gas pressure required to operate the
unit.
C. If it is additional or replacement equipment, have gas
authorities check pressure to make certain that existing
meter and piping will supply fuel at the unit with not
more than 1/2" water column pressure drop.
NOTE: When checking pressure be sure that all other
equipment on the same gas line is on. A pressure regulator is
supplied with SunFire Convection Ovens. Regulator is preset
to deliver gas at pressure shown on the rating plate.

Gas Inlet
The appliance and its individual shut-off 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 (3.45kPa.).
The appliance must be isolated from the gas supply piping
system by closing its individual manual
shut-off 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).
NOTE: In Canada, the installation shall be in accordance with
CAN/CGA-B149.1 Natural Gas Installation Code or CAN/CGA-
B149.2 Propane Gas Installation Code and local codes where
applicable.
NOTE: Adequate clearance must be provided for servicing
and proper operation.
Gas Connections
The 1" NPT inlet at the rear must be considered in piping the
gas supply for double stack units or 3/4" NPT for individual
(or single deck) connections. Undersized gas supply line(s)
may restrict the gas supply and affect performance. If other
gas appliances are supplied by the same supply line, the
supply line must be sized to carry the combined volume
without causing more than 1/2" pressure drop at the
manifold of each appliance on the line at full rate.
Electrical Connections
A 15 AMP service must be provided for each oven. For 115
VAC usage, a cord and plug (NEMA #5-15P) is provided but
connection to the electrical service must be electrically
grounded in accordance with local codes, or in the absence
of local codes, with the National electrical code, ANSI/NFPA
70-1990 (or latest edition). Each oven is electrically equipped
with a three-prong which fits all standard 115V three prong
grounded receptacle.
Wiring diagram is attached to the rear of the unit.
WARNING: Electrical Grounding Instructions
All ovens, when installed, must be electrically grounded in
accordance with local codes, or in the absence of local codes
the National electrical code ANSI/NFPA 70-1990 (or the latest
edition).
This appliance 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 unit.
