Desa FMH26TN 14 Connecting To Gas Supply, Extension Cord, Attaching Wood Base to Solid Floor

NATURAL GAS VENT-FREE FIREPLACE SYSTEM

INSTALLATION

Continued

Extension Cord

Use extension cord if needed. The cord must have a three-prong, grounding plug and a three-hole receptacle. Make sure cord is in good shape. It must be heavy enough to carry the current needed. An undersized cord will cause a drop in line voltage. This will result in loss of power and overheating. Use a No. 16 AWG cord for lengths less than 50 feet.

Attaching Wood Base to Solid Floor

For attaching base to solid floors (concrete or masonry)

Note: Floor anchors and mounting screws are in hardware package. The hardware package is provided with fireplace.

1.Drill holes at marked locations using 5/16" drill bit. For solid floors (con- crete or masonry), drill at least 1" deep.

2.Fold floor anchor as shown in Figure 22.

3.Insert floor anchor (wings first) into hole. Tap anchor flush to floor.

4.Insert mounting screws through base and into floor anchors.

5.Tighten screws until base is firmly fas- tened to floor.

CONNECTING TO GAS SUPPLY

WARNING: This appliance re- quires a 45° male flare fitting 5/8"- 18 UNF (Unified National Fine Thread) inlet connection and the flexible gas line provided.

WARNING: A qualified ser- vice person must connect fire- place to gas supply. Follow all local codes.

WARNING: Never connect fireplace to private (non-utility) gas wells. This gas is commonly known as wellhead gas.

IMPORTANT: Check gas line pressure be- fore connecting fireplace to gas line. Gas line pressure must be no greater than 14 inches of water. If gas line pressure is higher, fireplace regulator damage could occur.

CSA Design-Certified

Equipment Shutoff Valve

With 1/8" NPT Tap*

CAUTION:Use only new, black iron or steel pipe. Inter- nally-tinned copper tubing may be used in certain areas. Check your local codes. Use pipe of 1/2" or greater diameter to al- low proper gas volume to fire- place. If pipe is toovolume pres- sure will occur.

Installation must include an equipment shutoff valve, union, and plugged 1/8" NPT tap. Locate NPT tap within reach for test gauge hook up. NPT tap must be upstream from fireplace (see Figure 23).

IMPORTANT: Install main gas valve (equipment shutoff valve) in an accessible location. The main gas valve is for turning on or shutting off the gas to the appliance.

Check your building codes for any special requirements for locating equipment shutoff valve to fireplaces.

Apply pipe joint sealant lightly to male NPT threads. This will prevent excess sealant from going into pipe. Excess sealant in pipe could result in clogged fireplace valves.

CAUTION: Use pipe joint seal- ant that is resistant to liquid pe- troleum (LP) gas.

Sediment Trap

Figure 23 - Gas Connection

*Purchase the optional CSA design-certified equipment shutoff valve from your dealer. See Accessories, page 26.

We recommend that you install a sediment trap in supply line as shown in Figure 23. Locate sediment trap where it is within reach for cleaning. Install in piping system between fuel supply and heater. Locate sedi- ment trap where trapped matter is not likely to freeze. A sediment trap traps moisture and contaminants. This keeps them from going into fireplace controls. If sediment trap is not installed or is installed wrong, fireplace may not run properly.
