Pressure Regulations Adjustment - Wayne LC2300M Manual

H.5 ELECTRICAL CONNECTIONS:
The installation must be wired and grounded in accordance with local codes or in their absence,
with the National Electric Code ANSI/NFPA No. 70-2002 or latest edition.
In CANADA, all wiring shall be done in accordance with the Canadian Electrical Code.
H.6 SAFETY SYSTEM
The safety system (Including hatches, doors, water levels, pressure, and temperature systems)
must be installed according to current regulations. Power cables for the safety system must be
separated so incoming and outgoing signals do not cross within the same cable.
I. PRESSURE REGULATOR ADJUSTMENT
The pressure regulating gas valve (SKP25) is preset to 9 inches water column manifold pressure. This
may be field adjusted while the burner is in operation. Refer to Table 1 for pressure requirements.
When adjusting the (SKP25) regulator pressure according to that specified in Table 1, remove the
regulator cap for access to the slotted adjustment screw. Turning the screw counterclockwise reduces
burner inlet (manifold) pressure, clockwise increases the pressure. Reference Figure 9 for clarification.
