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 supply. This heater requires an external regulator (not supplied). Install the external regulator be- tween the heater and propane supply.

Installation Items Needed

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

external regulator (supplied by installer)

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. Pur-

chase the optional A.G.A. design-certified

manual shutoff valve from your dealer. See

WARNING: Never connect heater to private (non-utility) gas wells. This gas is commonly known as well-head gas.

CAUTION: Use only new, black iron or steel pipe. Inter- nally-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.

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).

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 14. 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.

CAUTION: Avoid damage to regulator. Hold gas 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 to 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

13.Pointing the vent down protects it from freezing rain or sleet.
