SECTION 9: GAS PIPING

WARNING
Fire Hazard
Connect gas supply according to Figure 21.
Gas line moves during normal operation.
Gas can leak if not installed properly.
Failure to follow these instructions can result in death,
injury or property damage.
A gas meter is connected to the service pipe by the
Gas Supply Company. An existing meter should be
checked, preferably by the gas company, to ensure
that the meter is adequate for the rate of gas supply
required.

Figure 23: Gas Connection with Stainless Steel Flex Gas Connector

Shut-Off Valve must be parallel to burner gas inlet. The 50 mm
(2") displacement shown is for the cold condition. This displace-
ment may reduce when the system is fired.
Do not bend flexible gas connector sharply.
Installation pipes should be fitted in accordance with
National Standards. Pipe work from the meter to the
heater(s) must be of adequate size. Pipes of smaller
size than the heater inlet gas connection should not
be used.
Connect the heater to the gas supply using an
approved flexible gas hose of 1 m (39") length and a
shut-off valve. See Page 31, Figure 23.
IMPORTANT - the complete installation must be
tested for gas soundness and be purged in accor-
dance with local and national codes.
