Big Maxx Horizontal Vent Kit

[Lantz]

I am hooking up my unit in Ontario and there is a door about two feet below where I want to put the exhaust exit. Is there a code issue with having the chimney over the door?

I rarely use the door if that matters.

My only other choice would be to go into the attic up a few feet and then through at the same point. I guess that I could also veer off at an angle to get it away from the door if it is still against code...but I really don't see it being an issue for a heater that will be used on occasion, but....

thanks

The book calls for:

"When horizontally vented, minimum clearance for termination
from any door, window, gravity air inlet, gas or electric meter,
regulators, and relief equipment is 4 ft."

Also if you are over a door you should also know that you have to watch the soffit:

Vent termination must be a minimum of 4' (1.2m) below or 4’
(1.2m) horizontally from any soffit vent or under-eave vent.

Along with living in Ontario I also have the same issue to deal with....question is do they mean diagonally for the door as well? They mention it for the soffit but not for the door.

thanks, I was thinking that it would be an issue. Is this an issue that the gas guy would have or is it a building code? Fortunately, I don't have the soffit issue as its a raised ranch with a pretty empty wall. I may have to go through my garage ceiling to get some more movement, but may just get someone in to tell me what to do.

I just noticed that the 45K can vent using a 3" pipe but the kit converts to a 4". I may take the kit back and swap it down depending on what I decide to do.

It'll be a gas code issue that your installer will deal with. Whether or not there's also building code issues depends on whether or not you pulled a permit for the work... regardless, your gas guy will do the work to the code he's obliged to comply with and should affix a tag on the unit with his installation and certification information.

Went through this for a wall heater installation a couple of years ago while also changing (propane) suppliers. My gas guy knew more about the code than the gas company.
