Installation
of
Manifold Plug
•
Remove
the
threaded hose
fitting,
turning
it
counter-clockwise with
a
wrench.
To
prevent
gas
leakage,
reapply sealant tape
to the
threads
of the
manifold
plug.
Then, screw
in
the
manifold plug
and
tighten with
a
wrench.
Note:
Do not
touch
the
combustion
chamber
nor
the
heat exchanger
to
avoid
the
risk
of

Check
of Gas
Leakage
Operate
the
GF3800/GF1800
at
high burner
mode,
and
check
for gas
leak from
the
manifold plug,
by
means
of
leak
test
solution (soap
and
water).
(See
Figure
B-1)
During combustion, check
for any gas
leakage
for
1
minute,
by
soap
and
water,
and
confirm
no
bubbles
on the
manifold plug.
•
If
bubbles
are
found,
it
indicates
gas
leakage.
Remove
the
manifold
plug
and
reapply sealant
tape
and
screw
it
back into
the gas
control
valve
and
repeat
the
leakage test.
•
After
the
leakage test
has
been completed,
press
the
[ON/OFF]
button
to
stop operation.
•
Wipe
