CONNECTING TO GAS SUPPLY
NOTICE
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.
Installation Items Needed
Before installing heater, make sure you have the items listed below.
• external regulator (supplied by installer, see
Figure 12)
• piping (check local codes)
• sealant (resistant to LP gas)
• manual shutoff valve *
• test gauge connection *
• sediment trap
• tee joint
• pipe wrench
* An A.G.A. design-certified manual shutoff valve with 1/8" NPT tap is an acceptable alternative to test
gauge connection. Purchase the optional A.G.A. design-certified manual shutoff valve from your dealer.
See Accessories, page 30.
INSTALLING
Continued
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 12. Pointing the vent down protects it from freezing rain or sleet.

WARNING
Never connect heater to private (non-utility) gas wells. This gas is commonly known as
wellhead gas.
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" diameter or greater to allow proper
gas volume to heater. If pipe is too small, undue loss of pressure will occur.
