We recommend that the following tools be used to connect the gas
couplings:
- T022: Compact open-end wrench (open-ended spanner),
SW27
- WK001: Torque wrench (spanner) with ratchet adapter and

• Remove the protective caps from the gas couplings on the pole
columns and the gas piping.
• Lubricate O-ring (5) per L5 and slide it onto the sleeve (6) so that
it is centered.
