S | Testing for gas leaks with an open flame | |
H | or other sources of ignition may lead to a | |
| fire or explosion and cause serious injury | |
| or death. Test in accordance with NFPA or | |
| local codes. |
!WARNING
An approved connector, suitable for the environment of equipment usage, is
required. Visible or excessive swaying, flexing and vibration of the gas
connections must be avoided to prevent failure. Neither the gas pipe nor the connector shall be placed in the ‘flue discharge area’.
!CAUTION
The fittings (nuts) on the flexible connector must be connected to an adapter. They may not be directly connected to the gas supply pipe.
!CAUTION
In high moisture or corrosive environments, use gas supply lines and connectors suitable for the environment. Periodically inspect for signs of failure or leakage.
This heater must be installed and serviced by trained gas installation and service personnel only.
The installation of this heater must conform with local building codes or, in the absence of such codes, the National Fuel Code (NFPA 54).
The gas outlet must be in the same room as the appliance and accessible. It may not be concealed within or run through any wall, floor or partition.
1.Install a sediment trap / drip leg if condensation may occur at any point of the gas supply line. This will decrease the possibly of loose scale or dirt in the supply line entering the heater’s control system and causing a malfunction. Note: High pressure gas above 14 in. W.C.P. (water column pressure) requires a high pressure regulator and ball valve (field supplied).
2.Form the stainless steel flexible connector (field supplied) into a smooth
Figure 2.5.
3.Attach the ball valve (field supplied) to the gas supply pipe. Apply pipe compound to NPT adapter threads to seal the joint. Use only a pipe compound resistant to liquid petroleum. NOTE: Provide a 1/8 in. NPT plugged tapping accessible for test gauge connection immediately upstream of gas connection to the heater (provided on ball valve, when supplied).
4.Attach the flexible connector to the adapter and burner control box inlet. Seal the joints.
NOTE: Excessive torque on the manifold may misalign the orifice. Always use two wrenches to tighten mating pipe connections.
5.Final assembly must be tested for gas leaks.
