Having problems with your Air Conditioners ?

Hi, I had a Cozy gas-fired room heater installed two years ago. It has only been used during the winter months. When it was installed , it passed the carbon monoxide test (0 parts per million). I had it checked today, and it failed the test, and the gas specialist said it might have to be condemned. Also, he said that 5 of 6 similar Cozy heaters that were fairly new failed testing this season. Have you heard about Cozy heaters having a similar problem? What can I do? Model: VC351A-H 3

Answers :

A very common problem with the unvented heaters is that they get dust and dirt in them and then they do not burn right. The pilot is especially bad and often that will make them burn bad failing the test.
Before throwing it out I would completely dismantle the heater and blow out everything with compressed air and then reassemble it. Take special care to blow everything out on the pilot assembly.
Also check the incoming pressure to the heater to make sure it is not too high. It should not be more then 7 In. WC for Nat. gas. If it is then have a regulator installed before the heater gas valve.

These things should get you to pass and be able to use your heater again.

My newly installed Valor Petrus HE gas fire keeps going out when I turn it to low heat. When I first light it I have it on high for approx 10 minutes before turning it down(fire has slide control) after a few minutes the fire goes out. My installer tested the chimney with smoke bombs and said it was OK, although he needed to remove the restrictor -I think that's what he said. Hoping you can advise what course of action to take next. Thank you.

I have a Lennox Gas Heater that will work for a while and then stop working (or fail to turn on when it cools down in the house). I changed the thermostat in the hallway about 6 months ago so I don't think its that. When the problem started about 2 months ago, flipping the breaker on and then off would kick the heater on and I wouldnt have the proboblem for about a few days and then the heater would fail to turn on again. Now flipping the breaker rarely works and the family is COLD! Please help

Rheem Power Vent gas water heater (only 2 years old) had electronic thermostat/gas valve fail. Received warranty replacement today but I can't get the old assembly out.

I have a Cozy one-sided gas wall heater. It is no longer lighting the burners when the wall thermostat reaches the temperature set point. The thermostat will "click" on, but the burners won't ignite in the heater. This has been an intermittent problem, but is growing steadily more frequent by the day. Sometimes when the burners won't ignite, I'll bang on the heater and then they ignite. But even that "temporary fix" is becoming less effective. What part on the wall heater needs to be replaced or

When we built our home 6 years ago, Airtron installed a Majestic NVBR36RN vented fireplace system. We had to turn our gas off a while back and never thought about the fireplace until now when we wanted to use it and realized the pilot wasn't lit. Airtron no longer installs fireplaces and was no help other than providing the model number they installed. I contacted a Majestic dealer and they showed me how to light the pilot on a model they had (said they weren't familiar with my model number).

It has a panel hidden under the white fiber hearth bricks at the front bottom of the unit. you need to clean the lava rock off of them, pull both of them up, and then you will see the hidden linear cover that allows you to access the valve and light. ... Air Conditioners
