Default hot water tank.

Hot water tank is in a poor placement. There is no room for mantenance. natural gas furnace in the same room. Maybe six by eight.

Tank right behind the natual gas furnce. A small inclosed furnice room.
The TPV leg is missing.


If the pipe is instaled it would be at a very poor location. 36 inches away from the furnace burner.

Question. Code on hot water tanks.
I could only find pans and the regular stuff.

#1 Can the be in a mechanical room with a natural gas furnace.

An inspection last year had hydro quebec move the tank outside the oil furnice room that was bigger than this one.
Thanks in advance.

What do you do when you run into the shaq (flip) from hell.
I am speeding countless hours and do not want to refer.
Can some one bring me a coffee.

I quite typically see the HWT and furnace in the same mechanical room. I know of no rules against it providing there is proper ventilation.

2009 IRC

"SECTION M1305
APPLIANCE ACCESS

M1305.1 Appliance access for inspection service, repair and
replacement. Appliances shall be accessible for inspection, service,
repair and replacement without removing permanent construction,
other appliances, or any other piping or ducts not
connected to the appliance being inspected, serviced, repaired
or replaced
. A level working space at least 30 inches deep and 30
inches wide (762 mm by 762 mm) shall be provided in front of
the control side to service an appliance. Installation of room heaters
shall be permitted with at least an 18-inch (457 mm) working
space. A platform shall not be required for room heaters.

Code commentary: Because mechanical equipment and appliances require
routine maintenance, repair and possible replacement,
access is required. Additionally, manufacturer’s
installation instructions usually contain access
recommendations or requirements. As a result, the
provisions stated herein supplement the manufacturer’s
installation instructions.

The provisions of this section specify that access
must be provided to components that require observation,
inspection, adjustment, servicing, repair or replacement.
Access is also necessary for operating
procedures such as startup or shutdown. The level
working space in front of the control side of the appliance
must be 30 inches (762 mm) wide and 30 inches
(762 mm) deep to provide adequate space for the
technician or inspector to safely perform the work.

The code states that “accessible” means “access
that might require the removal of an access panel or
similar removable obstruction.” An appliance or piece
of equipment is not accessible if any portion of the
structure’s permanent finish materials, such as drywall,
plaster, paneling, built-in furniture or cabinets or
any other similar permanently affixed building component,
must be removed before access is achieved. In
addition, removal of all or part of another appliance or
the piping or duct or serving other appliances must not
be necessary to perform the service, replacement or
inspection of an appliance. Such an installation could
result in unnecessarily high costs to the homeowner
and improper or unsafe reassembly of other appliance
and system components. This could also result in service
personnel having to perform disassembly and reassembly
of appliances and system components that
are not within the personnel’s area of expertise or licensed
work.

The intent is to provide access to all components
such as controls, gauges, burners, filters, blowers and
motors that require observation, inspection, adjustment,
servicing, repair or replacement."


"2009 IRC P2801.3 Location. Water heaters and storage tanks shall be
installed in accordance with Section M1305
and shall be
located and connected to provide access for observation, maintenance,
servicing and replacement."



“The things that will destroy America are peace at any price,
prosperity at any cost, safety first instead of duty first,
the love of soft living, and the get-rich-quick theory of life.”
Theodore Roosevelt

Thanks Joe.

Mechanical equipment needs maintenance therefor a reasonable amount of free room for qualified trades to work. I recommend a licensed professional evaluate the tanks work space installing the TPV leg.

I did not have that code.
In the vault.
Thanks everyone.

See manufacturer's installation instructions which is usually written on the appliance.

Its electric HWT.
As mentioned, a HI last year had Hydro Quebec installing the electric HWT out side in the garage due to an oil furnace in the small utility room.
#1 The TPV discharge had to be xx from gas and oil furnaces said the technician.
#2 Space for maintenance as Joe mentioned was another point of several codes they cited.
I'll try to get the scope in Quebec Marcel.

Water heaters requires little space on sides and rear (about 1 inch) a little more at front for servicing.

The furnace may need more space but then again clearance requirements are usually written on the furnace data plate.

I am not aware of any distance requirements for the TPR valve to furnace, only that it should terminate above floor about 8 inches.

As for installing the electric WH in the garage, I would be concerned if the garage isn't heated.
