c. Vacuum burner where it enters combustion tube.

d. Return air shutter to original position and replace screw.

HOW TO CLEAN PILOT MODELS -

1. Check main burner orifice and pilot assembly for contamination

(dirt, spider webs, etc.).

2. Clean main burner tube with small brush.

3. Main burner adjustment - open air shutter 1/4 way.

4. Low pilot flame. Check for contamination - if clean have the pilot

orifice replaced.

HOW TO CLEAN ELECTRONIC IGNITION MODEL

1. Check main burner orifice.

2. Clean and adjust main burner.

3. Main burner and valve manifold must align with each other

4. Check electrode for cracked porcelain (

5. Check electrode for proper gap - 1/8" between electrode and

ground.

6. If module board functions intermittently, remove board and clean

terminal block with pencil eraser (

WATER HEATER TANK CARE

SCALDING INJURY

Turn off water heater and allow time for water to cool before

•

removing drain plug to flush tank.

WINTERIZING (FLUSHING) INSTRUCTIONS

To insure the best performance of your water heater and add to the life

of the tank, periodically drain and flush the water heater tank. Before

long term storage or freezing weather drain and flush the tank.

1. Turn off main water supply (the pump or water supply (the pump or

water hook up source).

2. Drain Water Heater Tank by removing the drain plug. If the water

flows sporadically or trickles instead of a steady stream of water, we

recommend the following action; first open the Pressure

Temperature Relief Valve to allow air into the tank and secondly,

take a small ga8uge wire or coat hanger and poke through the drain

opening to eliminate any obstructions.

3. After draining the tank, because of the placement of the Drain Plug,

approximately two quarts of water will remain in the tank. This water

contains most of the harmful corrosive particles. To remove these

harmful corrosive particles flush the tank with either air or water.

Whether using air or water pressure, it may be applied through the

inlet or outlet on the rear of the tank or the Pressure Temperature

Relief Valve. (If using the Pressure Temperature Relief Valve the

Support Flange must be removed). The pressure will force out the

remaining water and the corrosive particles.

If you use water pressure, pump fresh water into the tank with the

assistance of the on-board pump or use external water for 90

seconds to allow the fresh water to agitate the stagnant water on

the bottom of the tank and force deposits through the drain

opening. Continue repeating adding water and draining until the

particles have been cleared from the water remaining in the tank.

4. Replace the Drain Plug and close the Pressure Temperature Relieve

Valve. the approximately two quarts of water remining in the tank after

draining will not cause damage to the tank should freezing occur.

PRESSURE-TEMPERATURE RELIEF VALVE

EXPLOSION

Do not place a valve, plug or reducing coupling on outlet part of

•

pressure-temperature relief valve.

A Pressure Temperature Relief Valve, dripping while the water heater is

running, DOES NOT mean it is defective. During normal expansion of

water, as it is heated in the closed water system of a recreation

vehicle, the Pressure Temperature Relief Valve will sometimes drip. The

Atwood water heater tank is designed with an internal air gap at the

top of the tank to reduce the possibility of dripping. In time, the

expanding water will absorb this air and it must be restored.

WARNING

SCALDING INJURY

Turn off water heater before opening pressure-temperature relief

•

valve to establish air space. Storage water must be cool.

TO REPLACE THE AIR GAP FOLLOW THESE STEPS:

1. Turn off main water supply (the pump or water hook up source).

2. Let water cool or let run until cool.

3. Open the hot water faucet closest to the water heater.

4. Pull handle of pressure temperature relief valve straight out and

allow water to flow until it stops.

5. Allow pressure temperature relief valve to snap shut; close faucet;

turn on water supply.

6. Turn on water heater and test.

• At least once a year manually operate pressure-temperature relief

valve (

10 ).

FIG

When pressure-temperature relief valve discharges again, repeat above

procedure. For a permanent solution, we recommend one of the following:

• Install a pressure relief valve in cold water inlet line to water heater

and attach a drain line from valve to outside of coach. Set to relieve

at 100-125 PSI.

• Install a diaphragm-type expansion tank in cold water inlet line.

Tank should be sized to allow for expansion of approximately 15 oz.

of water and pre-charged to a pressure equal to water supply

pressure. These devices can be obtained from a plumbing

contractor or service center.

FLUSHING TO REMOVE UNPLEASANT ODOR

A rotten egg odor (hydrogen sulfied) may be produced when the electro

galvanic action of the cladding material releases hydrogen from the

ater. if sulfur is present in the water supply the two will combine and

produce an unpleasant smell.

1. Turn off main water supply. Drain the water heater tank and reinstall

drain plug. Remove the pressure-temperature relief valve. Mix

solution of 4 parts white vinegar to two parts water. With a funnel,

carefully pour solution into tank.

2. Cycle water heater with the above solution, letting it run under

normal operation 4-5 times.

3. Remove the drain plug and thoroughly drain all water from the tank.

Flush the water heater to remove any sediment. You may flush the

tank with air pressure or fresh water. pressure may be applied

through either the inlet or outlet valves on the rear of the tank or

through the pressure-temperature relief valve coupling located on the

front of the unit.

TO FLUSH TANK WITH AIR PRESSURE

Insert your air pressure through the pressure-temperature relief valve

coupling. With the drain valve open, the air pressure will force the

remaining water out of the unit.

To flush tank with water pressure:

Fresh water should be pumped into the tank with either the onboard

pump or external water pressure. Continue this flushing process for

approximately 5 minutes, allowing the fresh water to agitate the

stagnant water on the bottom of the tank and forcing the deposits

through the drain opening.

4. Replace drain plug and pressure-temperature relief valve.

5. Refill tank with fresh water that contains no sulphur.

The Atwood water heater is designed for use in a recreation vehicle. If

you use your vehicle frequently or for long periods of time, flushing the

water heater several times a eyar will prolong the life of the storage

tank.
