9.0 MOUNTING THE APPLIANCE - continued
If a concealed gas connection is to be made ensure the gas supply pipe
is in it's final position and can enter the appliance in the correct position
when the appliance is hung on the wall.
Insert the wall mounting screws into the top wall plugs, taking care to
leave the screws
protruding
approximately 3/8"
from the wall. Now
hang the appliance
onto these screws
through
the
two
keyhole
shaped
holes in the back
panel
of
the
appliance.
Figure 7
Insert
the
lower
mounting screws into the lower wall plugs through the corresponding
holes in the lower part of the back panel. Do not tighten fully.
Before tightening the wall mounting screws fully, at this stage it is
recommended to check the horizontal alignment of the appliance with a
spirit level, as small adjustments can still be made if necessary. When
this has been checked, tighten all four fixing screws fully. To access the
upper fixing screws insert a screwdriver through the holes in the
deflector plates above the catalyst as shown in figure 7.
10.0 CHECKING THE BURNER
There are no imitation fuel bed components to install. The appliance
features a ribbon burner which is designed to produce a continuous
band of flame over its length. The burner should be visually inspected
to ensure it is free from any foreign matter. If it is necessary to clean or
dust off the burner then the glass door should be removed by removal
of the five retaining screws. Re-fit the glass door after cleaning or
inspection, ensuring a good seal.
11.0 CONNECTING A GAS LINE
IMPORTANT: HOLD HEATER REGULATOR WITH A
WRENCH TO PREVENT MOVEMENT WHEN CONNECTING
TO INLET PIPING.
A qualified gas appliance installer must connect the gas room heater to
the gas supply.
Consult all local codes. Route gas line using techniques and materials
prescribed by local and/or national codes. Only use pipe of 1/2" or
greater diameter to allow full gas volume to the gas fireplace. Undue
pressure loss will occur if the pipe is too small.
An ANSI approved manual shut-off valve and union must be installed
upstream of the heater within the fireplace cavity when rigid pipe is
used. Ensure that a sediment trap is installed upstream of the heater
(figure 8) within the structure's piping system to prevent moisture and
contaminants from passing through the pipe to the heater controls and
burner. Failure to do so could prevent the heater from operating reliably.
The heater gas inlet connection is 3/8" NPT at the regulator, located
below the burner, in the center of the heater. When tightening up the
joint to the regulator hold the regulator securely with a wrench to
prevent the regulator from moving.
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 10).
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
regulator on manual
models is preset and
locked
to
avoid
tampering. If the
pressure is not as
specified
in
the
Appliance Data sec-
tion on page 2,
Figure 9
replace the regulator
with P/N FT/F730031. Replace the test point screws after pressure
measurement ensuring no gas leaks. All instructions must be handed to
the user for safekeeping.
