Oven Construction
- 430 stainless steel exterior
- 304 stainless steel interior
- Powder coated steel legs
Theory of Operation
The HhC3240 conveyor oven uses two
independently-controlled blower motors to
precisely distribute impinged air into the cook
cavity from the top and bottom, creating a
highly-customizable cooking environment and
more throughput than any other oven its size.

Gas Setup
A digital manometer that will read 0.10” WC
(2.54 mmH
2
O, 0.249 mb) must be used to
properly set all pressures. If the minimum
pressure is not set correctly, the oven temperature
will slowly rise in stand-by mode and eventually
cause cooking issues as well as trip the high limit
temperature switch. Digital manometers (HHC-
3001) are available through TurboChef; call
800.90
TURBO (+1 214-379-6000) for pricing and
availability. For information on accessing the
burner control, see page 18.
Reading the Incoming Gas Pressure
(Static)
1. Ensure the oven and all the equipment in the
piping system are off (pilot lights are
acceptable).
2. Remove the burner compartment cover and
cooling fan tube (refer to page 1).
3. Remove the screw from the upper tap of the
gas valve.
4. Attach the digital manometer to the upper
tap of the gas valve (Figure 4). This tap will
show the incoming pressure before the
internal regulator of the gas valve.
5. The pressures must be no less than 6” W.C.
(152.4 mmH
2
O, 14.94 mb) and no more
than 14” W.C. (350.6 mmH
2
O, 34.87 mb).
Otherwise, severe damage to the equipment
can occur.
6. Reattach the screw to the upper tap of the
gas valve.
Reading the Gas Pressure at 100%
Flame
1. Ensure the oven is on.
2. Select a cooking profile.
3. Remove the screw from the lower tap of the
gas valve.
4. During warmup (both fan speeds are at 65%
and the oven is at 100% flame), attach the
manometer to the lower tap of the gas valve
(Figure 4).
5. Verify that the maximum operating pressure is
3.5” W.C. (88.9 mmH
2
O, 8.71 mb), unless
operating I
2L
gas.
NOTE: I
2L
gas requires a pressure of 4” W.C.
(101.6 mmH
2
O, 9.96 mb).
6. If not, use an 8mm nut driver to adjust the
8mm nut (Figure 4) until the manometer
reads 3.5” W.C. (88.9 mmH
2
O, 8.71 mb),
unless operating I
2L
gas, as noted above (turn
clockwise to increase the pressure, counterclockwise to decrease the pressure).
7. Reattach the screw to the lower tap of the
gas valve.

Reading the Gas Pressure at Minimum
Flame
1. Remove either the red or white wire
(Figure 4).
2. Attach the electric manometer to the lower
tap of the gas valve (Figure 4).
3. Verify that the minimum operating pressure is
0.10” W.C. (2.54 mmH2O, 0.249 mb).
4. If not, use a 5mm nut driver to adjust the
5mm nut until the electric manometer reads
0.10” W.C. (2.54 mmH2O, 0.249 mb) (turn
clockwise to increase the pressure, counterclockwise to decrease the pressure).
5. Reconnect the wire you removed.
6. If adjustments were made, re-check 100%
flame pressure (see adjacent procedure).
Reading the Operating Gas Pressure
1. Ensure the oven is on.
2. Select a cooking profile (page 10).
3. Remove the screw from the upper tap of the
gas valve.
4. During warmup (both fan speeds are at 65%
and the oven is at 100% flame), attach the
manometer to the upper tap of the gas valve
(Figure 4).
5. Ensure that the pressure is no less than 6”
W.C. (152.4 mmH2O, 14.94 mb)and no
more than 14” W.C. (350.6 mmH2O,
34.87 mb).
6. Reattach the screw to the upper tap of the
gas valve.
Confirming Proper Closure of all Taps
Additional testing may be required - always
adhere to local gas codes and required methods of
leakage testing in the immediate location (refer to
the regulations in force in the country in which
the appliance is being installed). The prevailing
authority is the local code (or regulations).
1. Turn on the gas supply.
2. Spray all gas connections with a soap
solution.
-If growing soap bubbles are observed, a leak
-is present. Immediately shut off the gas
-supply.
-If no growth occurs, the connections are
-intact. Turn off the gas supply.
