Installation Guide

CONNECTING TO GAS SUPPLY

WARNING: A qualied service technician must connect heater to gas supply. Follow all local

codes.

CAUTION: Never connect heater directly to the gas supply. This heater requires an external

regulator (not supplied). The external regulator between the gas supply and heater must be installed.

Gas supplier provides external regulator for natural gas.

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

as wellhead gas.

The installer must supply an external regulator for liquid propane. The external regulator is

provided by the gas supplier for natural gas. The external regulator will reduce incoming gas pres-

sure. You must reduce incoming gas pressure to between 11 and 14 in. of water column for propane

and between 6 and 14 in. of water column for natural gas. If you do not reduce incoming gas pres-

sure, heater regulator damage could occur. Install external regulator with the vent pointing down as

shown in Fig. 15. Pointing the vent down protects it from freezing rain or sleet.

* Purchase the optional equipment shuto valve from your local Home Center store.

INSTALLATION

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 ½ in. diameter

or greater to allow proper volume gas to heater. If pipe is too small, loss of pressure

will occur. Installation must include an equipment shuto valve, union, and plugged

1/8-in. NPT tap. Locate NPT tap within reach for test gauge hook up. NPT tap must

be upstream from heater (See Fig. 15).

IMPORTANT: Install equipment shuto valve in an accessible location. The equipment

shuto valve is for turning on or shutting o the gas to the appliance. 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.
