Installation Items Needed

 

CAUTION: Avoid damage to gas control. Hold gas

Before installing heater, make sure you have the items listed below.

For propane/LP units, the installer must supply an external regula-

tor. 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 point- ing down as shown in Figure 15. Pointing the vent down protects it from freezing rain or sleet.

CAUTION: Use only new, black iron or steel pipe. Internally-tinned copper tubing may be used in certain areas. Check your local codes. Use pipe of 1/2" diam- eter or greater to allow proper gas volume to heater. If pipe is too small, undue loss of volume will occur.
