Installation
Continued
IMPORTANT: The appliance and its individual shutoff 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 psig. (3.5 kPa). The appliance must be isolated from the gas supply piping system by closing its individual equipment shutoff valve during any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 psig. (3.5 kPa).
CAUTION: Do not kink flex- ible gas line.
CAUTION: Compounds used on threaded joints of gas piping shall be resistant to the action of Liquefied Petroleum (LP or propane), and should be applied lightly to ensure excess sealant does not enter the gas line.
1.Install a sediment trap between the incoming gas line and the gas control valve (see Figure 40). The sediment trap should extend down the center of the pipe. Refer to your local codes.
2.Prepare incoming gas line and check with local codes regarding the use of teflon tape.
Complete your gas line installation by con- necting incoming gas line with flexible gas line. Secure tightly with a wrench, but Do
NOT Overtighten.

WARNING: All gas piping and connections must be tested for leaks after the installation is completed. After ensuring that the gas valve is open, ap- ply a soap and water solution to all connections and joints. If bubbles appear, leaks can be de- tected and corrected. Do not use an open flame for leak testing and do not operate any appliance if a leak is detected.
WARNING: Improper installa- tion, adjustment, alteration, ser- vice, or maintenance can cause injury or property damage. Refer to this manual. For assistance or additional information, consult a qualified installer, service agency, or gas supplier.
Gas Supply Testing
Note: This section is intended as a guide for qualified service technicians installing gas to the appliance.
CAUTION: Do not connect appliance before pressure test- ing gas piping. Damage to the gas valve may result and an un- safe condition may be caused.
The millivolt system with a manual HI/LO ap- plies only to the DVF36TCR, DVF36TCRP, DVF36TCL and DVF36TCLP models. The gas control valve is accessible from the lower control compartment. Two pressure taps are provided on the gas control valve for a pressure gauge connec- tion (see Figure 41, page 22).
The electronic system applies to the DVF36TCRE, DVF36TCRPE, DVF36TCLE and DVF36TCLPE models (see Figure 42, page 22).
