INSTALLATION INSTRUCTIONS
GAS LEAKAGE INSPECTION
After connecting the piping, check the joints for gas leakage with gas leakage detector.
CAUTION
HOW TO CONNECT WIRING TO THE TERMINALS
A. For solid core wiring (or F-cable)(Fig.28A)
(1) Cut the wire with a wire cutter or wire-cutting pliers, then strip the insulation to about 25mm of the exposed solid wire.
(2) Using a screwdriver, remove the terminal screw(s) on the terminal board.
(3) Using pliers, bend the solid wire to form a loop suitable for the terminal screw.
(4) Shape the loop wire properly, place it on the terminal board and tighten securely with the terminal screw using a screw driver.
B. For strand wiring(Fig.28B)
(1) Cut the wire with a wire cutter or wire-cutting pliers, then strip the insulation to about 10mm of the exposed strand wiring.
(2) Using a screwdriver, remove the terminal screw(s)on the terminal board.
(3) Using a round terminal fastener or pliers, securely clamp a round terminal to each stripped wire end.
(4) Position the round terminal wire, and replace and tighten the terminal screw using a screw driver.

Item to the checked
5.5 Pay special care to the following and check after installation
Unproper installation may cause
Check
