CONNECTING | NOTICE |
TO GAS | A qualified service person must connect heater to gas supply. |
SUPPLY | Follow all local codes. |
| |
| |
| WARNING ICONG 001 CAUTION |
| Never connect heater directly to the propane supply. This heater |
| requires an external regulator (not supplied). Install the external |
| regulator between the heater and propane supply. |
|
|
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 the external regulator with the vent pointing down as shown in Figure 13. Pointing the vent down protects it from freezing rain or sleet.

| WARNING ICONG 001 CAUTION | |
| Use only new, black iron or steel pipe. | |
| tubing may be used in certain areas. Check your local codes. Use | |
| pipe of large enough diameter to allow proper gas volume to heater. | |
| If pipe is too small, undue loss of pressure will occur. | |
| Typical Inlet Pipe Diameters | |
| VP2000BTC | 3/8" or greater |
| VP2800BTC | 1/2" or greater |
| Installation must include a manual 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 14, page 15). |
|
| 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. | |
| WARNING ICONG 001 CAUTION | |
| Use pipe joint sealant that is resistant to liquid petroleum (LP) gas. | |
| Install sediment trap in supply line as shown in Figure 14, page 15. Locate sediment | |
| trap where it is within reach for cleaning. Locate sediment 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 | |
14 | installed wrong, heater may not run properly. | |
