2. Remove gas valve:
Remove the burner orifice(s) from the spud
holder. When converting from Natural Gas to

from front) must be removed. In place of the
removed orifice, a blank orifice (Part No.
M400995) and a Burner Opening Cover (Part
No. M413099) must be installed.
3. Install the new, correct burner orifice(s). Refer to
Figure 9
and
Table 2

4. Reinstall spud holder assembly to gas valve,
making certain burner orifice(s) are in line with
burner tube opening. Refer to

3. Connect a “U”-tube manometer (or similar
pressure gauge) to the burner orifice (manifold)
pressure tap.
4. Start tumble dryer and note pressure once flame
