Heater under a deck

[PoolGate]

Does anyone know the actual regulations regarding putting a gas heater under a deck? The deck is about 8 feet off the ground. Also does anyone know about putting it near a window for carbon monoxide emissions? PB was not much help.

I would think your building department for your city or county would have regulations for gas fired appliances in those cases.

I would not put it under a deck. Not sure about a window unless you leave it open alot.

Did you have to get a building permit for the pool and did the inspector pass this installation?

Take care.

Nothing is installed yet I am questioning the positioning of the pool equipment. Yes all permits are pulled but no work has been done to inspect.

I agree, talk to the permit department and inspectors.

Previous house my gas heater was near a bathroom window, but it was a fixed non-opening window so it was ok.

I doubt you can have the heater under the deck unless you are routing the exhaust gas up above the deck.

Pool heater should have clearances to windows and mechanical vents in the install instructions.
I don't think under the deck would be allowed by the national fuel gas code.

The heater installation guide shows the required clearances.

What exact heater did you get?

This is a great question. I am having the hardest time finding out exact models of what I am getting. It is Jandy 400k btu is all I know.

Agree, at least for Raypak heaters. The manual tells you what clearances the product requires.

I'm pretty sure that any heater needs to be at least 5 feet away from the pool. Definitely consult with your local permit office.

My PB said it should not be a problem under the deck as long as it has 5 feet of clearance. The bottom of the deck is a good 12 feet up. I asked about clearance on the sides as this is less than 5 feet (from the posts) and he didn't think this would be a problem. I wish heat pumps heated better this wouldn't be an issue then!

Thanks for the update.

Your building inspector will make sure the PB is up to code.

I would make sure to vent it correctly.

Personally, I wouldn't put it under a deck no matter what.

The plumber says it will be fine as long as we order the exhaust relocation kit. Check out my pics (sig line) to see how high the deck is. It is 7 feet above the top of the heater.

I read the manual too. The heater is rated for indoor use and outdoor use in a shelter. So it is fine where it is I am not sure it even needs the relocation kit.

 

[ps0303]

I would still check with local codes. Yes it is rated for indoor use and in a shelter with the proper vent.

DO NOT, under any circumstances, install the heater under ANY deck. -Pentair

Do not install the heater under a deck. -Jandy

9. Do not install under a deck. -Hayward

Don't install it under a deck.

A 400,000 btu/hr gas heater puts out a lot of hot exhaust, which might make people sick. Hot exhaust goes up.

 

[domct203]

You really need to consult with the building inspector. Ultimately it is up to them what is acceptable and what is not.

 

[JamesW]

It's important to follow the manufacturer's installation instructions in addition to any other applicable codes, laws, regulations etc.

If anything says don't do it, don't do it.

 

[PoolGate]

There is no inspection or code for this. It is the manufacturers instructions, which say it can be done. We'll see how it goes when running and add a remote chimney if needed.

 

[JamesW]

What installation manual are you using?

Jandy explicitly says don't put it under a deck.

Your first post says that the deck is 8 feet off the ground.

If the heater exhaust is 4 feet above the ground, then the exhaust is only 4 feet below the deck.

That's going to put a lot of very hot, toxic gas directly into an occupied area.

Actually it is under my Gazebo, which is 12 feet off the ground. The heater is 8 feet below the bottom of the Gazebo. See my pics.
