NATURAL GAS pressures with all gas appliances
running (tumble dryers, water heaters, space heaters,
furnace, etc.):
Maximum gas pressure – 10.5 water column inches
(26.1 mbar, 2.61 kPa)
Recommended gas pressure – 6.5 water column inches
(16.2 mbar, 1.62 kPa)
Minimum gas pressure – 5 water column inches
(12.4 mbar, 1.24 kPa)
An in-line pressure regulator may be required if the
line pressure exceeds 10.5 water column inches
(26.1 mbar, 2.61 kPa) with all gas appliances running.
LIQUID PETROLEUM GAS (L.P.) pressures with all
gas appliances running (tumble dryers, water heaters,
space heaters, furnace, etc.):
Maximum gas pressure – 13 water column inches
(32.3 mbar, 3.23 kPa)
Recommended gas pressure – 11 water column inches
(27.4 mbar, 2.74 kPa)
Minimum gas pressure – 10 water column inches
(24.9 mbar, 2.49 kPa)
For converting Non-CE models from Natural Gas to
L.P. Gas:

030 Series - M4703P3
T30 Series - M4707P3
035 Series - M4711P3
T45 Series - M4880P3
055 Series - M4924P3
CE GASES refer to
Installing CE Gas Drying
Tumble Dryers
section, the above data does not apply
to the CE.
Turn on gas and check all pipe connections (internal
and external) for gas leaks with a non-corrosive leak
detection fluid. Purge air in gas service line by
operating the tumble dryers in the drying mode. If
burner does not light and unit goes into lockout, open
and close the door and restart. Repeat these steps until
burner ignites.
Use pipe compound, resistant to
actions of L.P. gas, on all pipe threads.

WARNING
Check all pipe connections, internal and
external, for gas leaks using a non-
corrosive leak detection fluid. To reduce
the risk of explosion or fire, DO NOT USE
AN OPEN FLAME TO CHECK FOR GAS
LEAKS! Gas connections should be
checked twice a year for leakage.
