Residential duct humidifiers and Saddle Valves

[preetnep]

Hi
I m just wondering if one has to be 313 d licensed or G2 l8censed to install a humidifier ?

Regarding a gas furnace, technically you would need to be a G1, G2 or G3 as you will be modying the duct work which is by definition part of the appliance.  You would also be installing low voltage wiring inside the furnace.

From O. Reg 212/01,

Certificates required for various activities
6.  (1)  No person shall install, alter, purge, activate, repair, service or remove any appliance, equipment or other thing employed or to be employed in the handling or use of gas unless the person is the holder of a certificate for that purpose.  O. Reg. 212/01, s. 6 (1).

It means 313d can't do it.

I wonder with connection of the water supply line what we're allowed and not allowed to do. Since saddle valves are not allowed by building code (even tho 95% of all humidifiers are installed with one), I wonder if we need to be a plumber to then solder in a proper connection for the valve if one isn't already available?

Do you know where in the OBC it says that?  I have been looking and never could find anything about saddle valves.

Thank you!

7.2.10.5. Saddle Hubs
(1) Except as provided in Sentence (2), a saddle hub or fitting shall not be installed in drainage systems, venting systems or water systems.

(2) A saddle hub or saddle clamp may be installed in a building drain or building sewer of nominal diameter not less than 8 in. and that is in service provided that the connecting branch is at least two pipe sizes smaller than the run of the building drain or building sewer to which it is connected.

I bet only a plumber is certified to install a proper water valve.  I know in new construction the water valve is installed by them.

I don't think they're talking about the same thing when they say saddle hub.  saddle hubs are for water drainage, and not water supply.

I thought the same thing when I first looked through the OBC.  After Porcupinepuffer posted the Code reference, I re-read it and it does sound like it would apply to saddle valves.

Article 7.2.10.5(1) does refer to saddle fittings installed in water systems.

The Code defines a water system;

Water system means a water service pipe, a private water supply, a water distribution system, a fire service main or any part of any of them.
