Question about Williams 1403622 Gas Compact Heater

Open Question

My old williams model 300 direct vent gas heater has rusted out vent termination cap. if i could find a new cap with the same pipe dimensions i could make it work. even from new williams heater possibly. pipe dimensions are exhaust 4 3/8+ and intake 6 5/8-. my only other option would be to have the old rusted out part of the cap rebuilt if possible. would need a good sheet metal man for that. jerome hoffart.

SOURCE: The pilot light will not stay lit, I was told

Hi, this heater doesn't have a thermocouple, it uses a pilot generator which is more reliable so I doubt you need to change it out. First thing to check is that you have a clean "sharp" blue pilot, you should be able to hear it quietly roar. If it is yellow and appears "soft", the pilot need to be cleaned. The easiest way is to use a straw or tubing of some sort to blow into the pilot, gently tapping the pilot assembly. That should clean it up and heat the pilot generator properly. Tighten the the screw terminals at the control valve to assure good electrical connections and last but not least turn off the thermostat until you get a standing pilot. Good luck and stay warm.

SOURCE: I have a Williams Gas Space Heater Model#3501912.

I would suspect not. It's very, very rare for a control valve to go bad, unless someone tried to force it to urn with a pair of pliers or something similar.

If you have provided annual service to the heater, it's probably just residual gas remaining in the burners. To test this theory, turn the flames down to low and then turn the burner OFF. Do the burners and the pilot light go out? If it doesn't, you'll be that rare consumer that needs the Control Valve replaced.

Just to help you out a little bit more. I have provided a link to the Owners Manual for your heater. It's in a downloadable, printable, pdf format.

What is the minimum vertical vent distant from top of water heater to top of cap. Water heater is stand alone outside furnishing water for military force provider showers unit.


Generally 40 feet for ordinary atmospheric-vented household water heater...
Straight run to roof.
Atmospheric means no power vent... just hot air drafting upwards
Google search: gas vent height code

Atmospheric venting code depends on 4 basic factors:
Diameter of vent--- bigger vent, more draft
How many water heaters are connected to same vent
BTU per hour rating of water heater-- the more gas that is burned per hour, the bigger the vent needs to be
How straight the pipe is -- are there any horizontal or lateral runs

http://waterheatertimer.org/pdf/Bosch_Checking_the_draft.pdf
http://waterheatertimer.org/pdf/checking-the-draft2.pdf

Other factors can include
-wind conditions... higher wind across top of vent pipe on roof can reduce draft, and cause downdraft that blows deadly CO into same room as water heater
-vent termination near high walls, trees, high roof peak etc will reduce draft or cause downdraft
-amount of incoming air supply... if water heater is inside a closed room, then there is no air to draft up the pipe, burner will shut down or burn lazy yellow instead of clear blue
-stuff piled up around water heater that obstructs air intake
-dirty air intake screen that reduces air intake
-vent fans inside same room as water heater that pull air down the vent and cause reduction in water heater draft
-generally elbows reduce draft by 10%
-vent cannot terminate near any window door or air intake for another gas appliance
-bird build nest on top of vent pipe after vent termination falls off
-highly acidic gas by-product causes large amount of condensation inside pipe that burns hole in pipe or drips down and damages combustion parts...blower and inline condensate trap and drain might be required
-multiple water heaters installed on same vent line.

Gas water heater works fine but gas is detected with gas detection meter. We checked for all leaks with soap and water but found nothing. Where is the smell comming from?


It could be that the vent pipe is not drawing properly. It may be clogged with a nest of some sort. Also, look at the burner in side the water heater,. Is it completely lighting or just partially. It may need cleaning. Especially, if it appears to be rusted. That would cause incomplete combustion.

To check the "draw" of the vent pipe.Turn a hot water faucet ON and let it run, so that the water heater will fire up. Then take a stick match, light it and then blow it out. Quickly, before the smoke from the match disappears, place it next to the top of the heater where the vent pipe is connected. If it's functioning properly, it should quickly draw the smoke up the exhaust vent pipe. If it doesn't than the exhaust pipe may be partially clogged.

If the water heater is 10 or more years old, I highly recommend replacing it for a new one. The new models are more energy efficient. Plus, they're not overly expensive (approximately $300 depending on the capacity). Check with Lowe's and Home Depot.

Have a customer who has model # 1403622, when not in use the customer gets cold air coming inside from outside. suggestions?


This is a recurring problem with all Direct Vent Gas Appliances. Whether it be a Direct Vent Gas Fireplace or a Direct Vent Heater like you customer has. Not to mention, that they are very inefficient.

Unfortunately, there are only 2 solutions: Cover the direct vent outside when not in use. Of course, that means remembering to uncover it before each use. The other solution and the most efficient is replacing it with a properly sized Vent-Free Gas Heater or perhaps a Vent-free Gas Fireplace depending on what type and size room the present heater is in.

The following website as a lot of information o these types of products and how to properly size them.

My reliance sta-kleen 502 is leaking. The water is dripping on top of the pilot light, extinguishing the flame . Please advise me with step by step instructions to diagnose and attempt fix this myself....


If you have a leaking water heater there is a serious problem.
http://waterheatertimer.org/Water-heater-leaking.html
Page shows how to limp along on a leaking water heater if your water heater needs replacement.

One of three things is causing the water:
1) Loose water connection on top of tank that is dripping down inside tank >> check pipes on top of tank.

2) The vent is clogged or not working correctly causing condensation inside flue pipe.
Condensation water is dripping back down inside tank.
Problem means possible CO poisoning if gas is not venting.
Look at vent pipe to see if joints are corroded.
Use long fireplace match > light match and put into draft hood at top of tank and see if smoke goes up.
Put hand at draft hood opening when water heater turns on to see if vent gas enters home.
Do same test when furnace turns on to see if furnace vent is pushing back into water heater.
Does water heater vent inside same pipe as furnace? You may need to set up separate vent for water heater if furnace gasses are pushing back into home.
Check furnace vent for obstructions.
Look at vent stack top of home to see if hood is in place.
Check if bird nest is built inside warm vent pipe.
Improper flue is top priority for getting fixed so vent gasses properly escape home.
You may have to call a plumber.
Professional plumbing forum:
http://www.thetankatwaterheaterrescue.com/forums/forum3/

3) Your water heater is rusted out.
A rusted tank has to be replaced.
It cannot be repaired.
However, before replacing tank, you do not want a tank failure where tank ruptures and water runs inside home until water is shut off.
This will cause major damage.
Protect yourself first.
Turn off water valve above tank.
Move gas knob to 'pilot' so burner is not heating water.
Open tub spout on hot side to relieve pressure on tank so it will not rupture.

Now you're protected.
Link above shows how to limp along on failed tank until you can replace heater.

You need a new gas water heater from Lowes or Home Depot
Look at label on side of you tank for gallons and btu's of your water heater.
Measure height to flue pipe so you get same height water heater, so pipes don't have to be changed.
You need a pipe wrench and teflon tape which will be wrapped on each pipe thread when pipes are reassembled.

Step1) Drain water heater using valve at bottom of tank.
http://waterheatertimer.org/Water-heater-will-not-drain.html

2) Turn off gas valve going into heater.
When gas valve is perpendicular to gas line, then gas is off.
Dissemble gas line to water heater.

3) Disconnect flue pipe and support flue pipe with wire so it doesn't not fall down. Flue pipe joints should be held together at each joint with 3 screws.

4) Turn off water. Shut off valve is on COLD side.
Disconnect water pipes.

5) Move old water heater out of way.

6) Set new water heater in place. Put water heater in drip pan.

7) Connect water pipes >> cold goes to side marked cold.
Hot to hot.
Buy new flexible water connector pipes at home center for easy installation of water pipes.

8) Connect gas line exactly as it was connected before.
Home center sells flexible gas line connector for easy installation of gas line.
To test for gas leak after installation, mix liquid soap with water and put around gas line joints to see if there are bubbles.
Natural gas has less pressure than water lines, so gas pipes are easy to seal with ordinary wrench.

9) install TP pipe that runs to floor. Use old one off old heater.

10) Fill tank completely with water until water is coming out of tub spout.

11) Turn on gas, and light pilot as shown in manual.
New gas heater sometimes have small water leak when first fired up, so ignore a bit of water.

12) Save water heater manual like it is gold, and read everything in manual.

I have Wiiliams direct vent wall furnace. I smell gas only when pilot is on and burner is not on. It does not smell when it is fully running (burner is on)


Dear Alex191: I am shocked and amazed that the Williams heater company is STILL knowingly and willingly selling faulty direct vent gas heaters. My problems took place in 1988! I bought a 30,000 BTU Williams DIRECT VENT from The Home Depot. I took the time to remove window sashes and run gas line to the Williams heater that I had placed in the window aperture. I was glad to finally have heat and be able to heat the area of the house where I stayed. Then I began to smell gas when the Williams was OFF. I traced it to the area where the pilot light gas tubing entered the combustion chamber. I removed the Williams unit and replaced it with an identical make and model and the SAME THING HAPPENED!!! I sat on my bed and almost cried. I had the gas company come out and they labled the problem as a "fuzz leak". The warranty repairman came out and had no idea what to do. Tightening the retaining nut did nothing. I called Williams and even back then they said that they were aware of the problem. They called me back and wanted to send me a part and asked me, "Can you work on it?" I returned the Williams and bought a Perfection-Schwank CONSOL heater that burns the air in the room and vents horizontally to a 4 inch vertical gas vent and was very satisfied with it. When they went out of business I bought an "Empire" brand gas heater. I don't know if I'll ever buy another direct vent heater from anyone. I will be glad to write an affidavit should you decide to suit the Williams company.

Need to move the unit by dismantling


Remove the two screws on the side trim. Remove the two top screws from the filter panel. Reach behind the heater and pull the sock down on the vent pipe. unclip the two clamps holding the vent pipe together. Remove the plastic elbow off of the vent termination. Slide the heater to the left to slide the vent pipe off of the vent termination. Remove the gas line after shutting the gas off.
