INSTALLING HEATER
Continued
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 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 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. Copper tubing may be used in certain areas. Check your local codes. Use pipe that is 1/2" in diameter or greater to allow proper gas volume to heater. If pipe is too small, undue loss of pres- sure will occur.
The gas supply line to your heater must be 1/2 inch in diameter or larger. If the supply line branches to serve two or more heaters, the line from the branch back to the external regulator must be doubled or tripled, etc., in size (depending upon the number of heaters). Example for 1/2 inch diameter supply line: If the supply line branches to serve two heaters, the line diameter from the branch back to the external regulator must be at least 1 inch. If three heaters are served, the line diameter from the branch back to the external regulator must be at least 1 1/2 inches.
Note: If gas supply line total length exceeds forty feet, use a larger diameter pipe. Use pipe that is the next size larger than the heater control valve fitting.
