You have completed the installation. Now its time to make
sure everything works. Qualified electrical and mechanical
personnel should be available during the systems check and
the installation test.
Check all electrical connections
.
❒
Shut off power to the unit and verify that the GasTrac
and its burner controller are adequately grounded.
Inadequate grounding can cause controller error mes-
sages and nuisance alarms.
❒
With power off to the GasTrac and the host dryer, verify
that all terminal connections are tight and all new
wiring has adequate strain relief.
Check gas piping and ducting.
❒
Verify that the gas delivery piping is rigidly supported.
❒
Verify that exhaust gas ducting is secured, adequately
insulated and free of leaks.
Check the GasTrac fuel train for leaks.
Turn on the gas supply to the GasTrac. Open the primary
gas shutoff valve. Use a gas leak detection device or a
squirt bottle of soapy water to detect leaks around gas pipe
and fitting joints. Open the secondary gas shutoff valve,
and continue checking for leaks using the same procedure.
Start the host dryer.
Monitor the dryer during the first few minutes of operation
to verify that the start-up operating sequences are correct.
Turn on the gas supply to the GasTrac.
All manual shut-off valves in the gas supply line and the
GasTrac fuel train must be in the open position. Before
proceeding, use a detection device or soapy water to check
for gas leaks in the GasTrac fuel train.
Turn on main power to the GasTrac.
Turn the main disconnect dial to the
I
or ON
position.
If everything is installed correctly:
