Install Gas Piping - Carlin EZGas Pro Instruction Manual

Model EZGas Pro gas burner — Instruction manual
Where appliance instructions differ from this manual, follow the appliance instructions.
2. Install gas piping from meter to combination gas valve
Piping from meter to burner
Connect from the gas supply to the burner combination gas
valve inlet using new, clean black iron pipe and malleable iron
fittings only. Do not use copper, brass, cast iron or galvanized
pipe or fittings.
Provide support for gas piping. Do not rest weight of piping
on burner gas valve.
Apply pipe dope sparingly at all joints. Use only pipe dope listed
for use with propane gas. Do not use pipe sealing tape.
Do not hold gas valve with pipe wrench. Use crescent wrench
or other smooth-jawed device. Do not over-tighten.
Failure to comply with above could result in severe personal
injury, death or substantial property damage.
1. If possible, install a new gas line directly from the gas meter. If you
are using an existing gas line, verify it is clean and in good condition,
and verify it is large enough to handle the load of all connected appli-
ances.
2. When branching from a common gas line, do not tap off from the bottom
of horizontal sections — only from the side or top.
3. Install a main manual shutoff valve, sediment trap and ground joint
union near the burner combination gas valve connection as shown in
Figure 6.
4. If the burner is installed inside the appliance jacket, install the main
manual gas valve and sediment trap external to the jacket.
5. Size piping (or verify size) using Table 2. You will find additional informa-
tion on gas line sizing in the National Fuel Gas Code, ANSI Z223.1.
In the state of Massachusetts, when lever-type gas shutoffs
are used, they must be T-handle type only.

Gas supply pressure —
• Maximum supply pressure:
• Minimum supply pressure:
Do not expose the combination gas valve to gas pressure
in excess of 14 inches water column. Higher pressure could
damage the valve seat, resulting in potentially hazardous
condition. When pressure testing piping at higher pressures,
disconnect burner from gas line before testing.
If the gas supply pressure can exceed 14 inches water col-
umn at any time, you must install a lockup type gas pressure
regulator in the gas supply piping, ahead of the main manual
gas valve installed at the burner.
Test and purge gas line
Read WARNING above.
Pressure test and purge the line. Pressure testing should be done by the
gas supplier or utility, following all applicable codes.
