12.0 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 con-
trol compartment or on page 11).
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.

13.0 GAS PRESSURE CHECK

The pressure should be checked with the gas heater burning and the
control set to high flame.
The pressure test
Figure 5
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.
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
(mainfold test point
is located below the
left hand side of the
burner as shown in
figure 8.

tampering. If the
pressure is not as
specified
Appliance Data sec-
tion on page 2,
replace the regulator
with P/N H6063.
Replace the test
point screws after
pressure
measurement
ensuring no gas
leaks. All instructions
must be handed to
the
safekeeping.

14.0 SPARK GAP

The gap between the
spark electrode and the
pilot should be 1/8" to
3/16" to produce a good
Retaining clip spark. There should be no
need to adjust this. If
under any circumstances
the piezo electric spark
fails, the pilot cannot be lit
manually.

15.0 ASSEMBLY OF THE GLASS FACIA

1. Remove the glass panel from all packaging and lay face down on a
soft surface. Identify the top and bottom of the glass facia by
observing the orientation of the keyhole shaped slots in the facia
fixing brackets as shown in figure 10.
