INSTALLATION

CONNECTING TO GAS SUPPLY

WARNING: A qualified

service person must connect

heater 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.

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.

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.

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

" NPT tap is

an acceptable alternative to test gauge connection. Purchase the optional

CSA/AGA design-certified equipment shutoff valve from

your dealer. See Accessories, page 17.

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

reach for cleaning. Locate

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

installed wrong, heater may

not run properly.

IMPORTANT: Hold pressure

regulator with wrench when

connecting it to gas piping and/or

fittings.

CAUTION: Use pipe joint

sealant that is resistant to

natural gas.

Figure 13 -Gas Connection

Installation must include an equip-

ment shutoff valve, union, and

plugged 1/8

" NPT tap. Locate NPT

tap within reach for test gauge hook

up. NPT tap must be up stream from

heater (see Figure 13).
