These sections have all been combined into a single cat­egory under Annex G in the new document. This has been done because many of the requirements within these sections were con­sidered to be subjective in nature, and difficult if not impossible to enforce. To reflect this, the words “shall” have been replaced with “should”.

While there are many arguments for and against the revisions to these sections, we urge members to do their best to comply with the recommendations posted within this annex. This will help to ensure WETT maintains a positive, professional reputation in the minds of the public.

Hazardous Locations This section can now be found under clause 4.3 in the new document. Language dealing with the installation height of appliances has been clarified. The wording now reads, “Any component representing a source of ignition, such as a blower or the bottom of the firebox, is at least 450 mm (18 inches) above floor level.” The old wording was open to much interpretation. It stipulated that the “appliance” must be mounted 18 inches above floor level.

To be sure, the height of the appliance’s pedestal or legs was being factored in as part of the appliance. This resulted in platforms that were taller than they needed to be to satisfy the intent. Even with the revision, installers will still need to check with their local-authority-having jurisdiction as to what they want to see to satisfy the requirement for protection against physical damage. Venting Flue Gases Tees are now required in certain liner applications. This new clause (6.2.7) stipulates that a tee is mandatory for a liner system connected to a free-standing space heater, or a hearth-mounted stove that is rear-vented. This does not apply to fireplace inserts or to hearth-mount appliances that are top-vented. Why the change?

It just makes good sense to use a tee in these applications as is it improves inspection and maintenance access. If you were already doing this anyway – good for you! Section 6.4.2 in the new code makes some subtle changes to the requirements for horizontal sections of single-wall flue pipe that should not be overlooked. The wording has been revised to ensure that effective lengths of elbows are factored in when determining the overall length of a horizontal flue pipe.

Before, it could be interpreted that 3 m (10 feet) of straight pipe was permitted along with up to 180 degrees of elbow. This was never the intent.

It is important to note that a 90 degree elbow is roughly equivalent to five feet of straight pipe in terms of resistance. Mxkey 35 rev 27 download. You would be at maximum hori­zontal flue pipe length with single-wall pipe if you used just two ninety degree elbows or four forty-five degree elbows.
