SECTION 9: GAS PIPE WORK

WARNING

Explosion Hazard

Leak test all components of gas pipe work before operation.

Gas can leak if pipe work is not installed properly.

Do not high pressure test gas pipe work with heater connected.

Failure to follow these instructions can result in death, injury or property damage.

It is important that the gas supply pipe and the electrical connections do not support any of the heater’s weight.

A gas meter is connected to the service pipe by the gas supply company. An existing meter should be checked, preferably by the company, to ensure that the meter is adequate for the rate of gas supply required.

Installation pipes must be fitted in accordance with local and national codes. Pipe work from the meter to the heater(s) must be of adequate size.

9.1 Connections

Connect the heater to the gas supply ensuring that the final connections are as follows:

Gas supply pipe work is run in medium or heavy gauge tubing in compliance with local and national codes.

The gas supply pipe is adequately sized to carry the total volume of gas for the complete installation.

An isolating valve and union connection should be used and fitted into the supply adjacent to the heater.

For suspended heaters, use an approved metal flexible connection between the isolating valve and the heater. To reduce pressure loss, use one pipe size larger than the heater gas connection.

IMPORTANT - The complete installation must be

purged and tested for gas soundness in accordance with local and national codes.

Check the pipe and tubing ends for leaks before placing heating equipment into ser- vice. When checking for gas leaks, use a soap and water solution; never use an open flame
