INSTALLATION

CONNECTING TO GAS SUPPLY

WARNING: A qualified service person must connect heater to gas supply. Follow all local codes.

WARNING: This appliance requires a 3/8

"

NPT (National

Pipe Thread) inlet connection to the pressure regulator.

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

Inlet Pipe From Natural

Gas Meter (7” W.C. to

10.5” W.C. Pressure)

IMPORTANT: Check your gas line pressure before connecting heater to gas line. Gas line pressure must be no greater than 10.5 inches of water. If gas line pressure is higher, heater regulator damage could occur.

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 large enough diameter to allow proper gas volume to heater. If pipe is too small, undue loss of pressure will occur.

Figure 13 -Gas Connection

*A CSA/AGA design-certified equipment shutoff valve with 1/8

"

NPT tap is an acceptable alternative to test gauge connection. Purchase the CSA/AGA design-certified equipment shutoff valve from your dealer.

Typical Inlet Pipe Diameters

All models up to 20,000 BTU’s use

3/8’’ or greater pipe;

All models 25,000 BTU’s and higher, use 1/2” or greater pipe.

Installation must include an equipment 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 Figure13).

IMPORTANT: Install an equipment shutoff valve in an accessible location. The equipment shutoff valve is for turning on or shutting off 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.

Install sediment trap in supply line as shown in Figure 13. Locate sediment trap where it is within r e a c h f o r c l e a n i n g . L o c a t e sediment 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 i n s t a l l e d w r o n g , h e a t e r m a y not run properly.

CAUTION: Use pipe joint sealant that is resistant to natural gas.

IMPORTANT: Hold pressure r e g u l a t o r w i t h w r e n c h w h e n connecting it to gas piping and/or fittings.
