I need to know safety clearances for a 30,000 BTU LP Gas Heater. I plan to wall mount it, and it is not vented.

Are unvented heaters allowed in your area? They aren’t alllowed in my area anymore. I have a second house with a unvented decorative gas fireplace/stove. Yes it has CO2 dectector but it is a mechanical device . The other point is this thing dumps a ton of moisture in the air, creating condensation issues and the it also seems to aggravate asthma problems. Personally you could not give me an unvented gas heater. If I move to that house I will be replacing it with a vented model.

Each manufacturer sets minimum clearance specs for its equipment and then (I believe) the building code requirement for clearance typically is to comply with the particular manufacturer's specs.

Your HVAC contractor should be able to help you.

The clearances required are in the installation manual. Mr Heater for example is against the wall on the supplied mount, xx inches from the floor, x inches from a side wall. That style of heater is illegal in some countries and some states in the US.

I checked the manual with the heater. No clearances are given. Seems silly not to include such important information.

The manufacturer may have a website and the instruction manual may be on that site.

Nothing on the website and you want to install this DYI. Probably a reason there is nothing on the website.

Hmm, not vented. I am suspect of this, even if it was in a garage. I believe they have a safety shutoff if too much CO2 is detected so you might be ok. Might want to check it has that first though.

Heater has a safety switch for CO2. Could not locate manual so looked on line. No information on line.

Every actually legit sellable combustible appliance has the clearance e requirements either in the manual or online. Even my cheapie from Northern in the barn had clearance instructions.

I’d be very very leery of some likely cheepchinesecrapola ventless product. There are many reasons that lots places do not allow them. If you move forward with this product, you need to buy several carbon monoxide detectors.

If you can find no information online or in print for this heater, what do you expect to do when it breaks? To keep it working correctly you need to know make, model number, and have access to a list of companies who can install and maintain it. Installing and maintaining a gas heater takes some knowledge and experience.
