WARNING: DO NOT

attempt to convert this

water heater for use with

a different type of gas

other than the type shown

on the rating plate. Such

conversion could result in

hazardous operating

conditions.

Pressure Testing the Gas Supply System

The appliance and its individual shutoff

valve must be disconnected from the gas

supply piping system during any pressure

testing of that system at test pressures in

excess of 1/2 psi (3.5 kPa).

The appliance must be isolated from the

gas supply piping system by closing its

individual manual shutoff valve during

any pressure testing of the gas supply

piping system at test pressures equal to or

less than 1/2 psi (3.5 kPa).

Gas Supply

The branch gas supply line to the water

heater should be clean 1/2” black steel

pipe or other approved gas piping

material.

A ground joint union or ANSI design

certified semi-rigid or flexible gas

appliance connector should be installed

in the gas line close to the water heater.

The National Fuel Gas Code (NFGC)

mandates a manual gas shut-off valve: See

(NFGC) for complete instructions.

If flexible connectors are used, the

maximum length shall not exceed 36”.

Compound used on the threaded joints of

the gas piping must be of the type resistant

to the action of LP gas. Use compound

sparingly on male threads only.

Where a sediment trap is not incorporated

as part of the appliance, a sediment trap

shall be installed downstream of the

equipment shutoff valve as close to the

inlet of the appliance as practical at the

time of the appliance installation. The

sediment trap shall be either a tee fitting

with a capped nipple in the bottom outlet

or other device recognized as an effective

sediment trap. DO NOT use excessive

force (over 31.5 ft lbs.) in tightening the

pipe joint at the gas control (thermostat)

inlet, particularly if teflon pipe compound

is used, as the valve body may be

damaged.

The inlet gas pressure to the water heater

must not exceed 10.5” w.c. for natural gas,

or 14” w.c. for LP gas. For purposes of

input adjustment, the minimum inlet gas

pressure (with main burner on) is shown

on the water heater rating plate. If high or

low gas pressures are present, contact your

gas supplier for correction.

Leak Testing

The water heater and its gas connections

must be leak tested at normal operating

pressures before it is placed in operation.

Turn on the manual gas shut-off

valve near the water heater.

Use a soapy water solution to test for

leaks at all connections and fittings.

Bubbles indicate a gas leak that must

be corrected.

The factory connections to the gas

control (thermostat) should also be leak

tested after the water heater is placed in

operation.

WARNING: Never use

an open flame to test for

gas leaks, as property

damage, personal injury, or

death could result.

High Altitude

This water heater is certified for

installations up to 10,200 feet above sea

level.

!

WARNING: Installations above

10,200 feet are not authorized and may

result in improper and inefficient

operation of the appliance, producing

carbon monoxide gas in excess of

acceptable limits, which could result in

serious injury or death.

WARNING: Failure to

install a water heater

suitable for the altitude at

the location it is intended to

serve, can result in improper

operation of the appliance

resulting in property

damage and/or, producing

carbon monoxide gas, which

could result in personal

injury, or death.
