14.0 CHECKING THE GAS CONNECTIONS
Turn on gas supply and test for gas leaks using a gas leak test solution
(also referred to as bubble leak solution).
NOTE:
Using a soapy water solution (50% dish soap, 50% water) is
an effective leak test solution, but it is not recommended, because the
soap residue that is left on the pipes/fittings can result in corrosion
over time.
A.
Light the appliance (refer to the lighting instructions label in the control
compartment or on Page 14
)
.
B.
Brush all joints and connections with the gas leak test solution to
check for leaks. If bubbles are formed, or gas odor is detected, turn
the gas control knob (off/pilot/on) to the “OFF” position. Either tighten
or refasten the leaking connection, then retest as described above.
C.
When the gas lines are tested and leak free, be sure to rinse off the
leak testing solution.
D.
Observe the individual tongues of flame on the burner. Make sure all
ports are open and producing flame evenly across the burner. If any
ports are blocked, or partially blocked, clean out the ports.
15.0 GAS PRESSURE CHECK
The heater regulator controls the burner pressure which should be
checked at the pressure test points located on the control valve itself
(shown in Figure 7
)
for burner (manifold) and regulator (inlet) setting
pressures.
The pressure should be checked with the gas heater burning and the
control set to high flame.
The pressure test points are located on the gas valve. To access the
valve and the test points, firstly remove the control knob spindle from
the valve spindle by removing the retaining clip shown in Figure 5.
Burner (Manifold) Pressure
WARNING
Never use an open flame to check for leaks.
Withdraw the control knob and spindle from the heater, remove the
gas valve cover plate by removing the four retaining screws indicated
in Figure 6.
The pressure test points are located as shown in Figure 7. An alternative
burner (manifold test point is located below the left hand side of the
burner as shown in Figure 8
)
.
The pressure regulator on manual models is preset and locked to avoid
tampering. If the pressure is not as specified in Table 1 on Page 3,
replace the burner assembly (see Page 16 for ordering information).
Replace the test point screws after pressure measurement ensuring no
gas leaks. All instructions must be left in the possession of the user for
safekeeping.
