Gas Supply Line Requirements
The Installer/Owner is responsible for furnishing and installing gas supply lines, valves,
regulators, and accessories.
When installing gas supply lines and accessories, observe the following:
a.
Refer to Figure 3-2 for the recommended layout of the gas supply lines.
b.
Use non-hardening pipe thread sealant resistant to LP gas.
c.
The ¾” NPT gas inlet is on the bottom of the 24CGP10. See Figure 3-2
d.
Install main manual shut off valve between the gas supply and the appliance. See Figure 3-2.
This main manual shut off valve is called the “Main Manual Gas Valve.”
e.
Install a sediment trap (drip leg) in gas supply line. See Figure 3-2.
3.
Test Gas Supply Lines
a.
Check all connections for proper tightness.
b.
Remove the control side panel to inspect internal gas connections. Do not replace the panel
until installation is complete.
c.
Open the gas supply valves.
d.
Check all lines and connections for leaks, both inside and outside this appliance, with soap
and water solution.
e.
All leaks must be corrected before attempting to operate this appliance.
4.
Pressure Test Gas Supply Lines
If pressure testing is required, this appliance must be disconnected or isolated from the gas
supply piping system during pressure testing as follows:
•
The appliance and its individual shutoff valve (Main Manual Gas Valve) must be
disconnected
from the gas supply piping system during any pressure testing of that system
at test pressures in excess of 1/2 psi (14” water column or 3.45 kPa).
•
The appliance must be
isolated
from the gas supply piping system by closing its individual
manual shutoff valve (Main Manual Gas Valve) during any pressure testing of the gas supply
piping system at test pressures equal to or less than 1/2 psi (14” water column or 3.45 kPa).
