Bosch NGP745UC - 30"4 Burner Cooktop NGP Series Gas Installation Manual page 9

Connect Gas Supply
The gas inlet to the unit is located at the right rear of rough-in box. After installing
a gas shut-off valve in an easily accessible location under the unit, install the pres-
sure regulator (supplied) to manifold pipe using Teflon tape on threads of manifold
pipe. To prevent possible damage to the gas pressure regulator, install it after the
rough-in box is in its permanent position.

Connect the gas supply line to the unit pressure regulator using a 1/2" flex gas line

cedure in Figure 6.)

Secure regulator to cooktop gas inlet using approved Teflon tape. Turn to hand
tighten plus 1/4 turn, not exceeding 1 turn for alignment.
Check supply line connections for leaks using a soap solution. Do not use a flame
of any sort.
1) Turn on gas.
2. Apply a non-corrosive leak detection fluid to all joints and fittings in the gas
connection between the shut-off valve and the range. Include gas fittings and
joints in the range if connections may have been disturbed during installation.
Bubbles appearing around fittings and connections indicate a leak.
3. If a leak appears, turn off supply line gas shut-off valve and tighten connec-
tions.
4. Retest for leaks by turning on the supply line gas shut-off valve. When leak
check is complete (no bubbles appear), test is complete.
5. Wipe off all detection fluid residue.
