Flame Pack Series 400 Operation and Service Manual
8.0: Filling the Fuel Cylinder
1.
Connect the refill assembly to a take of 40% hydrogen/60% nitrogen fuel (see Figure
6). Verify contents by checking the specification tag or sticker (see Section 20).
2.
Crack cylinder valve momentarily to blow dirt and/or water out of the refill assembly.
3.
Remove end cap from the Flame Pack’s check valve.
4.
Make sure the check valve connection is clean.
5.
Make sure the Flame Pack is not lit and the fuel valve is closed. Connect check valve
to refill assembly. Gently snug fitting. Do not over tighten.
6.
Ensure purge (“bleeder”) valve is closed (see Figure 6).
7.
Stand to the side of the gauge. This safety procedure is to protect personnel in the
unlikely event any loose components project. Open the cylinder valve slowly until the
pressure gauge reading stops increasing. Observe and note the reading on the
pressure gauge.
NOTE:
the FP tank may warm up with initially filled. This is normal as the temperature
of metal tanks rises slightly when pressurized.
CAUTION:
never tighten or loosen fittings under pressure.
8.
Close the cylinder valve.
9.
Open the purge (“bleeder”) valve to relieve pressure in the fill assembly, then close it
(see Figure 6).
10.
Disconnect the Flame Pack from the fill assembly.
11.
Reinstall end cap finger-tight. Slight force using the open-end wrench provided will
keep the end cap from coming off while surveying with the Flame Pack. Replace the
end cap if lost.
End caps serve two important functions: they protect threads on check valve, and they
prevent dirt and debris from entering Flame Pack.
12.
Remove intake assembly from FP and unscrew primary filter housing. Remove insert
side of QC body, spring, bronze filter, and washer.
13.
Place primary filter housing up to fill assembly, manually seal around housing, open
valve on fill tank for a quick one-second spray to blow dust and debris from intake
assembly.
14.
Replace filter.
NOTE:
To fully utilize fuel when filling the Flame Pack’s cylinder, a cascade fueling
system can be used on multiple tanks.
WARNING!
The hydrogen/nitrogen fuel mix is a high-pressure combustible gas. This fuel must be handled
with the proper care. Remember,
NO SMOKING
or
OPEN FLAMES
when fueling Flame Pack.
