2. Remove stainless steel top trim strip from lower unit if not
already removed.
3. Tip upper unit backward. Remove vent patch at lower
rear if not if not already removed.
4. Place 1” x 4” x 65” (25mm x 100mm x 1650mm) long piece
of lumber across the rear top of oven to prevent stacks
from misarranging.
5. Place the flue connector on the lower unit with extended
part to the right of the unit. (Fig 1)
6. Raise the top oven section up and onto the lower oven
section.
7. Carefully remove piece of lumber ensuring lower section
flue connector inserts into upper section vent hole.
8. Assemble the interconnecting gas piping as shown and
connect to rear gas inlets.
Gas Connection
1. The appliance must be isolated from the gas supply
piping system by closing its manual shut-off valve during
any pressure testing of the gas supply piping system at
test pressure equal to or less that 1/2 psig. (3.45 kpa.).
2. The appliance and its 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 psig. (3.45 kpa.).
NOTE: The ovens should not be installed on the same line
with space heaters, broilers or other equipment with high
intermittent demand.
3. When making gas connections, uses a pipe joint
compound that is resistant to the action of liquefied
petroleum gases.
4. Each oven is supplied with two possible gas connection
locations. One is located on the right side and the other is
located on the right rear corner.
5. The right side connection is plugged with a 3/4 counter
sunken plug. If this connection is used, you must cap the
rear connection.
6. The gas pressure regulator is part of the combination
valve and is adjusted to yield a pressure of 6.0” water
column for natural gas and 10” water column for propane
gas.
7. A separate shut-off valve for each oven must be provided.
It should be as close as possible to the place where the
gas line goes into the oven. It must be located so that it is
easily accessible. A handle or wrench should be chained
to the valve where it will always be at hand.
8. For a stack of two ovens, two shut-off valves, one for each
oven must be provided.
