4.0 UNPACKING
When unpacking, caution should be exercised to see that the equipment is not handled roughly.
The crate must be removed carefully. The machine must not be used to pry against when
removing the crate. Gas-fired heaters are usually shipped completely assembled and require no
further attention prior to installation.
5.0 GENERAL INSPECTION
When the unit is unpacked, make a visual inspection looking for missing parts or damage, which
may have occurred during shipment. All electrical and mechanical connections should be checked
for tightness, as vibration during transit may cause them to loosen.
6.0 GAS LINE & FLUE INSTALLATION
Only qualified technicians familiar with local and national codes should install the gas line and the
flue.
The exhaust flue should be as short as possible. A typical installation would include a drip
leg.
Caution:
Check for gas leaks using appropriate devices.
7.0 ELECTRICAL INSTALLATION
Connect the proper power supply (check nameplate) through a main line disconnect (field supplied)
to terminal connections L1, L2, L3 and ground in the control cabinet. This is only power required as
the unit is completely pre-wired and supplied with a control voltage transformer to supply 110 volts
to the control circuit. Connect the interlock wiring from the desiccant dryer control panel to the gas
heater control panel as shown on the electrical schematics for each assembly. Verify the correct
rotation of the combustion blower assembly with the directional labels on the unit. Install the
process thermocouple in the hopper inlet duct.
Refer to the electrical wiring schematics for complete details.
