CONNECTING TO GAS SUPPLY
WARNING: A qualified service person must connect heater to gas supply. Follow all local codes.
CAUTION: Never connect heater directly to the propane/LP supply. This heater requires an ex- ternal regulator (not supplied). In- stall the external regulator between the heater and propane/LP supply.
Installation Items Needed
Before installing heater, make sure you have the items listed below.
• external regulator (supplied by installer) | |
• piping (check local codes) | |
• | sealant (resistant to propane/LP gas) |
• | equipment shutoff valve * |
The installer must supply an external regulator. The external regulator will reduce incoming gas pressure. You must reduce incoming gas pressure to between 11 and 14 inches of water. If you do not reduce incoming gas pressure, heater regulator damage could occur. Install external regulator with the vent pointing down as shown in Figure 6. Pointing the vent down protects it from freezing rain or sleet.
CAUTION: Use only new, black iron or steel pipe. Inter-
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 heater (see Figure 7).
IMPORTANT: Install equipment shutoff valve in an accessible location. The equip- ment shutoff valve is for turning on or shutting off the gas to the appliance.
Apply pipe joint sealant lightly to male threads. This will prevent excess sealant from going into pipe. Excess sealant in pipe could result in clogged heater valves.
CAUTION: Use pipe joint seal- ant that is resistant to liquid pe- troleum (LP) gas.
We recommend that you install a sediment trap in supply line as shown in Figure 7. 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 heater controls. If sediment trap is not installed or is installed wrong, heater may not run properly.
