WARNING

FIRE OR EXPLOSION HAZARD,
CAN CAUSE PROPERTY DAMAGE,
SEVERE INJURY OR DEATH.
1. Do not force the gas control knob on the appli-

ance. Use only your hand to turn the gas con-
trol knob. Never use any tools.

2. If the knob will not operate by hand, the con-

trol should be replaced by a qualified service
technician.

GAS CONTROL KNOB SETTINGS
Gas control knob settings are as follows:

OFF: Prevents main gas flow through the control.

ON: Permits gas to flow into the control body. Under

control of the thermostat and direct ignition module, gas
can flow to the main burner.

NOTE: Controls are shipped with the gas control knob in

the ON position.

PERFORM GAS LEAK TEST

WARNING

FIRE OR EXPLOSION HAZARD,
CAN CAUSE PROPERTY DAMAGE,
SEVERE INJURY OR DEATH.
Check for gas leaks with rich soap and water solu-
tion any time work is done on a gas system.

GAS LEAK TEST:

1. Paint pipe connections upstream of gas control with

rich soap and water solution. Bubbles indicate gas leak.

2. If leak is detected, tighten pipe connections.

3. Stand clear of main burner while lighting to prevent

injury caused from hidden leaks that could cause flashback
in the appliance vestibule. Light main burner.

4. With main burner in operation, paint pipe joints

(including adapters) and control inlet and outlet with a rich
soap and water solution.

5. If another leak is detected, tighten adapter screws,

joints, and pipe connections.

6. Replace part if leak cannot be stopped.

TURN ON SYSTEM

Rotate the gas control knob counterclockwise

to

ON.

TURN ON MAIN BURNER

Follow instructions provided by appliance manufacturer

or turn thermostat up to call for heat.

CHECK AND ADJUST GAS INPUT AND BURNER
IGNITION

CAUTION

1. Do not exceed input rating stamped on appli-

ance nameplate, or manufacturer recommended
burner orifice pressure for size orifice(s) used.
Make certain primary air supply to main burner
is properly adjusted for complete combustion.
Follow instructions of appliance manufacturer.

2. IF CHECKING GAS INPUT BY CLOCK-

ING GAS METER: Make certain there is no
gas flow through the meter other than to the
appliance being checked. Other appliances must
remain off with  their  pilots  extinguished  (or
their consumption must be deducted from the
meter reading). Convert flow rate to Btuh as
described in Gas  Controls  Handbook, form
70-2602, and compare to Btuh input rating on
appliance nameplate.

3. IF CHECKING GAS INPUT WITH MAN-

OMETER: Be sure gas control is in OFF posi-
tion before removing outlet pressure tap plug
to connect manometer  (pressure  gauge).  Also
turn gas control knob back to OFF when re-
moving gauge and replacing plug. Before re-
moving inlet pressure tap plug, shut off gas
supply at the manual valve in the gas piping to
the appliance or, for LP, at the tank. Also  shut
off  gas  supply  before  disconnecting manom-
eter and replacing plug. Repeat Gas Leak Test
at plug with main burner operating.

Standard Pressure Regulator

1. Check the manifold pressure listed on the appliance

nameplate. Gas control outlet pressure should match the
nameplate.

2. With the main burner operating, check the gas con-

trol flow rate using the meter clocking method or pressure
using a manometer connected to the outlet pressure tap on
the gas control. See Fig. 4.

3. If necessary, adjust the pressure regulator to match

the appliance rating. See Table 5 or 5A for factory-set
nominal outlet pressure and adjustment range.

a. Remove pressure regulator adjustment cap screw.
b. Using  a screwdriver,   turn  inner  adjustment

screw clockwise

to  increase or counter-

clockwise

to  decrease gas pressure to

burner.

c. Always replace cap screw and tighten firmly to

prevent gas leakage.

4. If desired outlet pressure or flow rate cannot be

achieved by adjusting the gas control, check gas control
inlet pressure using a manometer at the gas control inlet
pressure tap. If inlet pressure is in the normal range (see
Table 5 or 5A), replace gas control. Otherwise, take the
necessary steps to provide proper gas pressure on the
control.
