BLUE FLAME 10,000 BTU
PROPANE/LP GAS HEATER
CONNECTING TO GAS SUPPLY
NOTICE: A qualified service per- son must connect heater to gas supply. Follow all local codes.
CAUTION: Never connect heater directly to the propane/LP supply. This heater requires an external regulator (not supplied). Install the external regulator be- tween the heater and propane/LP supply.
Installation must include a manual shutoff valve, ground joint 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 13).
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.
Install sediment trap in supply line as shown in Figure 13. Locate sediment trap where it is within reach for cleaning. 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.
IMPORTANT: Hold pressure regulator with wrench when connecting it to gas piping and/or fittings.
The installer must supply an external regu- lator. The external regulator will reduce incoming gas pressure. You must reduce incoming gas pressure between 11 and 14 inches of water. If you do not reduce incom- ing gas pressure, heater regulator damage could occur. Install external regulator with the vent pointing down as shown in Figure
12.Pointing the vent down protects it from freezing rain or sleet.
