INSTALLATION
It is the responsibility of the purchaser to ensure the oven is
installed in a manner to meet all local codes . In the absence
of local codes, applicable national codes are referenced in this
booklet . In the case of discrepancy between the information
in this booklet and local codes, it is recommended you
consult your local inspector(s) . This appliance meets or
exceeds all applicable regulations and standards in effect on
its date of manufacture .
Location
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 . Installation must conform to local codes or, in
the absence of local codes, with the National Fuel Code, ANSI
Z223 .1, Natural Gas Installation Code, CAN/CGA-B149 .1, or the
Propane Installation Code, CAN/CGA-B149 .2, as applicable .
Wall Clearance
This oven, single or stacked, must be installed with adequate
clearance to combustible and non-combustible walls .
Sides: 1 inch [25 mm]
Back: 3 inches [76 mm] for gas ovens, and
6 inches [152 mm] for electric ovens .
Garland recommends that a one inch clearance be
maintained between this oven and any other cooking
appliance .
Garland recommends that this oven not be installed with a
broiler or open burner appliance immediately adjacent to the
right side .
Each appliance shall be located with respect to building
construction and other equipment so as to permit access to
the appliance . Such access and clearance may be necessary
for servicing and cleaning .
GAS CONNECTIONS
The type of gas for which the oven is equipped is stamped on
the data rating plate . It is located inside the lower front trim
cover . Connect an oven stamped “NAT” to natural gas only .
Connect an oven stamped “PRO” to propane gas only .
If the oven is being installed into a new location, have gas
authorities check the meter size and piping to assure the supply
line has a sufficient amount of gas pressure to operate the oven .
If the oven is a replacement or additional appliance to an
existing installation have gas authorities check the pressure
to ensure the existing meter and pressure will supply the
oven with no more than a 1/2” water column pressure drop .
Note: When checking the gas pressure make sure all other
appliances on the same gas line are turned on .
A pressure regulator is supplied with Garland convection
ovens . The regulator pressure is preset to deliver the gas
at the pressure shown on the rating plate . Do not install
an additional regulator where the unit connects to the
gas supply unless the gas pressure exceeds the maximum
recommended pressure .
The oven 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 .45 kPa) .
The oven must be isolated from the gas supply piping system
by closing its individual manual shut-off valve during any
pressure testing of the supply system at test pressures equal
to or less than1/2 PSI (3 .45 kPa) .
Prior to connecting to the building gas supply the lines
should be purged of all metal filings, pipe thread compound
or other debris .
The gas connection piping (3/4” for single ovens, 1” for
stacked ovens), must be considered when planning the
supply line . Undersized gas supply lines may restrict the
gas flow and affect performance . If other gas appliances are
supplied by the same supply line, it must be sized to carry
the combined volume required for all the appliances without
causing a more than 1/2” pressure drop at the manifold of
each appliance on line at full rate .
Recommended supply pressures are 7” ± 5% WC for natural
gas (NAT) and 11” ± 5% WC for propane (PRO) . The inlet
pressure for the supply line must not exceed 13 .8” WC natural
and 15”WC for propane .
Two ovens stacked may be supplied by a single gas line . The
minimum recommended size of a single supply line for two
stacked ovens is 1 inch .
Assemble the gas pipes and fittings provided in the stacking
kit as shown in the Figure 3 on page 7 . Use a pipe thread
compound that is intended for use on propane gas piping .
Be sure to check for leaks before finalizing the installation . Use
appropriate solutions or detection devices .
Installations in which a flexible gas connection hose is
used, require the supplied strain relief to be installed at the
lower left rear corner of the base . Install the strain relief in
accordance with applicable codes . The strain relief must limit
the movement of the oven to prevent unnecessary stress on
the flexible connector .
